If you travel from the Earth to the moon, which of the following measurements would change? Mass

Weight

Density

Size

Answers

Assuming you are talking about the individual in space, Size and Weight changes in space due to the difference in gravity. Astronauts grow taller in space due to the micro-gravity they experience out of the earth's atmosphere.

It would not be:
Mass : Because mass is a measurement not dependent on gravity
Density : Astronauts do not blow out in bubbles once they leave the earth's atmosphere, therefore, we can deduct that density stays the same

Your weight - mass is the amount of matter you are made of, therefore that would not change. Weight takes into account the gravitational force of the planet you are on, and as the pull of gravity is different on earth to the moon, your weight would vary.

An experimental procedure requires 10 ml of acid to be dissolved into a beaker of water. An additional 5 ml of acid is added to the solution. Which statement best describes the new solution?

Answers

If we dissolve 10 mL of acid into a beaker of water. The acid will be diluted.
Since the number of moles of acid will not change, we can use this formula:
M1 V1 = M2 V2

Where M is the concentration of the acid in the solution
V1 = 10 mL
and
V2 = Vwater + 10

If we add an additional 5 mL of acid, the new concentration of the acid will be:
M = (M1 (5mL) + M2 (Vwater + 10mL)) / (5mL + Vwater + 10mL)

The concentration of acid in the new solution will increase.

Long story short, C is the answer.

How are science and technology related?A. Technology is a branch of natural science.
B. Science is a branch of technology.
C. Advances in science may lead to advances in technology and vice versa.
D. Science and technology are not related

Answers

It's not A because technology is a branch of applied science. It's not B because again, technology is a branch of science, not the other way around. It's not D because they are related with one being a branch of another. Therefore, it has to be C because scientific advances do lead to technological advances.

C. Advances in science may lead to advances in technology and vice versa is the correct answer~

Sodium's atomic number is 11. What does this tell you about an atom of sodium?

Answers

This tells us that an atom of sodium contains 11 electrons which is balanced by 11 protons. The atomic mass of the atom is then the sum of the protons and neutrons. If you know the atomic mass of sodium, you can subtract 11 (protons) to get the number of neutrons.

7 characteristics that can be used to describe minerals

Answers

Hardness, cleavage, fracture, color, streak, luster, and tenacity.
Hope this helps :)

Final answer:

Minerals can be described using 7 key characteristics: color, streak, luster, crystal form, hardness, cleavage, and density. These characteristics provide detailed information about a mineral's geological properties.

Explanation:

The characteristics used to describe minerals are generally located in the detail of their geological properties. These characteristics include:

Color: The appearance of the mineral in natural light.
Streak: The color of the mineral in powdered form.
Luster: The way a mineral reflects light, either metallic or non-metallic.
Crystal Form: The external shape of the mineral crystal.
Hardness: A measure of the mineral's resistance to being scratched.
Cleavage: The manner in which the mineral breaks along regular planes.
Density: The mass per unit volume of the mineral, measured by specific gravity.
