HELP- "During an investigation a scientist heated 27 g of mercuric oxide till it decomposed to leave a dry product. The total mass of the product formed was 25 g. Does the law of conservation of mass hold true in this case? Use complete sentences to justify your answer based on numerical calculations." WHATS THE ANSWER.
Answer:
, if we see we are considering this initial mass of this in this particular case, the initial mass of substantiated- or we can say, mercury oxide heated, it is, we can say, 27 grains. So this is the initial mass which is heated here. It is like this and what we can say we can consider this consent, passion of mass, so consummation of mass. We are looking here, the log, the conservation of the mass, so conservation of mass state at mass. It is always converted, but if it's not the case, we can also modify it it through mass and energy. They are combined converted or we can say, mass energy equivalence here so mass. It is confirmed in this case, so we can say, but here it is said that initially mass was 27 gram and finally mass was 25 gram. So but as we know, mass it is conserved mass, it is always conserved, so if the mass it is conserved, we should say this thing that the lost in the 2 gram weight must be due to the evaporation or we can say formation of the gases which Have been escaped, that is why it cannot be recorded, so we can say 2 gramos in the mass to the escape of the gas, or we can say evaporation. So.

List three evidences that show that the Bible is the Word of God.
Answer:1.God tells us that He is the Author (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))
1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)
3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.
Explanation:
Answer:
Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.
The Word of God: Evidence that Scripture is Divine
First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.
Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

Which of the following statements is correct with regard to convection currents?
A. Convection currents in magma are caused by color differences.
B. Convection currents in magma drive the movement of tectonic plates.
C. Convection currents in magma are a result of how the magma is formed.
D. Convection currents in magma play a role in the movement of Earth's inner core.
Answer:
A.convection currents in magma are caused by color differences
The thermal conduction we find that the correct answer is:
a) Convection currents in magma are caused by hot differences.
Thermal conduction occurs in three ways
Conduction. When two material are in thermal contact with different temperatures, energy flows from the hottest material to the coldest, in this there is no material movement Radiation. Due to the absorption of radiant energy between bodies with different temperatures, it does not need physical contact, which is why it is the form of transmission in a vacuum. Convention. This occurs when a mass of liquid or gas is in contact with another colder mass and the material of the hotter mass moves upward in the cold mass, this form of heat transfer includes the movement of material, it is very important in liquid and gases.
The magna of volcanoes is a quantity of matter in a liquid or plastic state due to the thermal energy of the interior of the earth, when this mass reaches a colder and fissured area, it can rise towards the coldest part, breaking and deritating. the materials in its path.
Let's annotate the different statements
a) True. According to the explanation, the temperature of the magna causes it to rise due to convection currents.
b) False. The cracks are those that help the convection currents, in general the movement of the plates creates cracks
c) False. The movement of the plates is independent of the convection of the magna which is approximately vertical
d) False. The core of the planet is very deep (> 4000 km) and the magna currents reach about 14 to 20 km
In conclusion using the forms of thermal conduction we find that the correct answer is:
a) Convection currents in magma are caused by hot differences.

Discuss one component of your school's recycling system that could be automated and predict the economic impact.
One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.
Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.
The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.
Answer:
Our school has color coded virtual trash cans. For example, a trash can for only paper will only accept paper items, if the item put inside is not paper, it will litter it out and all students have cleaning duties throughout the week so even if you or someone litters you’ll probably have to clean it up at some point anyways. I honestly think it’s very cool. (i wish this was true smh).

2. The angle if refraction is always less than the angle of incidence as shown in the table. If you were to calculate the averages of all 3 test, it would still be smaller than the angle of incidence.
3. The angle of refraction is always less than the angle of incidence because the light ray must be moving from a optical density than air hence the light ray could seem bended. This is because the the speed of a wave is determined by the medium through it is passing. When light speeds up as it passes from one material to another, the angle of refraction tends to be larger than the angle of incidence. An example of this would be when light passes from water to air or glass to water. This change also makes the image look shifted to the side.

Which of the following forces has not changed Earth's surface?
folding
erosion
weathering
gravity
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Answer:
(i did number 1) James Watt was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine. In 1762, he began studying steam engines. With his knowledge, in 1763, he repaired a "Newcomen" engine owned by the university. However, while repairing it, he was impressed by its waste of steam, and came upon a solution, the separate condenser. It was his first invention, and he created it in 1769. In 1765, he produced his first working model of the 'Watt' engine (with separate chambers for piston and steam). (i rly hope this helps no need to mark branliest if it doesnt)
