How many molecules of hydrogen (H2) and Oxygen (O2) are needed to make
eight water molecules with no leftovers?
Answer: 8 oxygen, 16 hydrogen
Explanation:
One oxygen mixed with two hydrogen makes water, which gives us the simple relation of 1:2 multiply by the variable at hand, in this case 8, which gives us 8 oxygen, 16 hydrogen
For this assignment, you will develop several models that show how light waves and mechanical waves
are reflected, absorbed, or transmitted through various materials. For each model, you will write a brief
description of the interaction between the wave and the material. You will also compose two typewritten
paragraphs. The first will compare and contrast light waves interacting with different materials. The
second will explain why materials with certain properties are well suited for particular functions.

Explanation:
In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
What needed to be present in marine mud to form fossil fuels?
Carbon and Hydrogen.
Answer:
Mostly decaying organisms are needed to present in marine mud to form fossil fuels.
Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

A sample of ice undergoes a physical change by being melted in a beaker. The ice cube had a mass of 30 grams. What will be the mass of the liquid water? How did you determine this?
Answer:
it would still be 30 grams.
Explanation:
it would still be 30 grams because you are not adding any more water to the beaker and you are not taking any of the melted water away
How does an atom change if all of its electrons are removed?
p.s. I'll mark the first answer the brainliest if it is correct! ;)
a. The atom’s volume increases.
b. The atom’s mass increases.
c. The atom becomes positively charged.
d. The atom becomes negatively charged.
c. The atom becomes positively charged
if the electrons are removed it means theres no longer a negative charge to balance the positive charge of the protons in the atom

Think about a stalk of corn. You can see it has roots, a stalk, and leaves. You know it reproduces with pollen from the tassels falling onto the silk of ears. You can’t see the cells in it without a microscope. What evidence could you gather just from the observation that a corn stalk is more likely to be made of eukaryotic cells and not prokaryotic cells?
Answer:
The cells of which the corn plant is made up of are eukaryotic cells.
EXPLANATION:
They have all the features such as nucleus and organelles such mitochondria and an endoplasmic reticulum. More primitive forms of life such as bacteria are prokaryotes and lack these things except they do have ribosomes like eukatyotes. Genetic information is processed differently in prokaryotes and eukaryotes but that is another question altogether.;)

C. It may slow down.
D. It may slow down or speed up.
E. It will stay stationary.
Answer:b
Explanation:
which of the following statements beast describe how the organelles cycle carbon through the biotic and abiotic factors of an ecosystem .
Answe: Biotic factors are the living things in an ecosystem so they do not recycle. Abiotic factors are the different physical and chemical components available like temperature, air, water, minerals, rocks,and PH. Not ll of them are recycled.
Answer: A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
