What is a chemical equation ?Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Considering the equation given from the question
H₂CO₃ —> H₂O + CO₂
Reactant
H = 2 atomsC = 1 atomO = 3 atomsProduct
H = 2 atomsC = 1 atomO = 3 atomsFrom the description of the reactant and product, w can see that the atoms in both reactant and product are the same. Hence the equation support the law of conservation of mass

Explanation:
Why is the use of the inquiry process (or scientific method) a practical way to approach science?
1. The inquiry process is a practical way to approach science because the inquiry process begins by asking questions and moving on from there.
2. In science it is important to investigate phenomena or certain subjects by posing questions that you would like to answer through the scientific method.
3. Therefore, the inquiry method is connected because to inquire on a subject requires raising questions which is an essential step in scientific discovery.
Why are scientific theories modified, but seldom discarded?
1. If a theory cannot explain new evidence or observations then the theory is revised or even thrown
out, but if the theory still explains a wide range of observations and evidence then it is revised
rather than discarded.
2. it will still hold some value as above as you learn more you tweak your hypothesis to fit the ever expanding amount of info and data you collect and assimilate
3. The only way they ever go away is if people stop working on them.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

In our experiment that will compare how long it will take for 100 ml distilled water to evaporate from a from a 5" diameter container. This will be the control group. For the experiment group, we will use 100 ml of distilled water and dissolve 10 grams of table salt in the water. We will use the same diameter dish for both samples so the same amount of water surface is exposed to the air.
What would a good hypothesis be?
When the salt water was almost evaporated, the higher concentration of salt might have slowed the evaporation process by blocking the air from the moisture.
We think that a pure water sample will dissolve faster than a salt water solution because salt adds more mass to equal quantities of liquids.
It took a total of 31hrs. 15 min. to evaporate the pure water and 32hrs. 10 min for the salt water.
We poured the water into each 5" dish and set the containers on a table. We noted the time: 8:00 a.m. Saturday.
Answers
Answer:The answer is C: How long does it take distilled water to evaporate from a 5” diameter container?
Explanation:
In the air, a salt solution will evaporate more slowly than pure water.
What is Evaporation?
The process by which a liquid transforms into a gas state is called evaporation. A surface phenomena, that is. The amount of evaporation depends on the humidity. If the air is humid, it is virtually saturated, which means that evaporation will occur at a much slower rate.
Since evaporation takes place on the liquid's surface, the salt molecules that are present on the water's surface prevent as much water from evaporating. As a result, salt water evaporates more slowly than pure water.
As a result, the salt solution will evaporate from the air more slowly than pure water.

Which of these statements best describes which traits are expressed by an organism? A. An organism expresses all the traits for which it carries genes.
B. An organism expresses only the traits whose genes are inherited from a parent.
C. An organism expresses only the traits whose genes it will pass on to its offspring.
D. An organism expresses some traits for which it carries genes while others are dominant
Answers
The statement that best describes which traits are expressed by an organism is A.
An organism expresses all the traits for which it carries genes. This is because an organism's traits are determined by the combination of genes it carries, which includes both dominant and recessive genes. Even if a trait is not expressed in an organism, it can still be carried in its genes and passed on to its offspring. Therefore, all the traits for which an organism carries genes have the potential to be expressed in either the organism or its offspring.
B-An organism expresses only the traits whose genes are inherited from a parent.

What is a mixture?A mixture is when two or more substances mix with each other without participating in a chemical change. The combining substance does not lose its properties or individuality in a mixture.
In other words, the components of a mixture each keep their original properties.
Since mixtures are chemically combined, they can be easily separated by physical means.

B. all the offspring of a set of parents have identical genes
C. Each parent passed all of it's genes to every offspring
D. Only one parent is required to produce offspring
Answers
Answer:
b
Explanation:
their genetics come from the same two parents so if their genetics looked different it would mean that a offspring wasnt one of the parents.
To solve this, we must know each and every concept behind reproduction. Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.
What is reproduction?The process through which organisms duplicate themselves is known as reproduction. In general, reproduction is among the most essential notions in biology: it involves creating a replica, a likeness, and so ensuring the survival of species.
Their genetics are derived from the exact two parents, thus if their genetics differed, it meant that an offspring was not one of the mom and dad. "All the offspring of a set of parents have identical genes" best describes this kind of reproduction.
Therefore, all the offspring of a set of parents have identical genes best describes this kind of reproduction. the correct option is option B.
