Use the image above to answer the question: Roger collected four rock samples and wrote a description of how each was formed. Which of the following rocks that Roger collected is a metamorphic rock?
A. Formed from magma that cooled slowly
B. Formed by pressure and heat over time
C. Formed from lava that cooled quickly
D. Formed by pieces of rock cemented together
Answers
Answer:
B
Explanation:
Cause metamorphic rock is formed by heat pressure overtime
The rock collected by Roger if it is metamorphic rock it is formed by pressure and heat over time. Hence, image image B represents a metamorphic rock.
What are metamorphic rocks ?Metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created.
These kinds of conditions can be found deep inside the Earth or where tectonic plates collide. The process of metamorphism changes the rocks into denser, more compact rocks rather than melting them.
Either by the rearranging of mineral constituents or through chemical reactions with fluids that enter the rocks, new minerals are produced. Even rocks that have already undergone metamorphosis might undergo changes due to pressure or temperature. Many metamorphic rocks are bent, smeared out, and compressed.
Therefore, option B is correct.

Answer:
Magnesium oxide
Explanation:
When magnesium reacts with oxygen, the magnesium atoms donate electrons to O2 molecules and thereby reduce the oxygen. Magnesium therefore acts as a reducing agent in this reaction. The O2 molecules, on the other hand, gain electrons from magnesium atoms and thereby oxidize the magnesium.

Photosynthesis is the process in which plants harness energy from the sun to make their own nutrition. The process converts light energy into chemical energy through cellular respiration.
Explanation:
Just to start you off. I hope it helps! (❛ ᴗ ❛)
Answer:
Photosynthesis is the process which a plant makes it's own food. The plant get energy from the sun and water from the soil. The plant lets the suns energy flow though so it touches all the parts that need it. When it get the water from the soil it goes into the stem and to the leaves. Photosynthesis is important because it benefits the air and us too. We can also help by put carbon dioxide. Photosynthesis is part the life cycle of a plant.

An advantage of using renewable energies is? 1.They are harmful to the environment 2.We have a limited supply of them 3.They allow us to take energy from natural processes
Answers
Answer:
3. They allow us to take energy from natural processes
Explanation:
There are two major sources of energy namely: renewable and non-renewable. Renewable sources of energy are those natural sources that gets replenished faster than they are utilized, which is contrary to non-renewable sources. Examples of renewable sources of energy are wind energy, solar energy, hydro (water) energy.
According to the question, one advantage or merit that renewable sources have over their counterparts is that they allow us to take energy from natural processes e.g. wind, sunlight etc.
6. How many molecules are in 2.7 moles of carbon dioxide

2.7×6.022×10^23
=16.594×10^23 moleclules
Explanation:
number of mol= 2.7
1 mol of any element=6.022×10^23
therefote 2.7 mol =2.7×6.022×10^23
=16.594×10^23
So, saying you have a mole of iron atoms is like saying you have 6.022 • 10 to the 23 power iron atoms
There for you have 1.63 • 10 to the 24 power

How many moles of Mg3(PO4)2 are in 350.00 grams of Mg3(PO4)2?
Answers
Answer:
1.3 moles/ 1.33150727 moles
Explanation:
350g x 1 mol/262.86g = 1.3 moles
The molar mass of Mg3(PO4)2 is 262.855 g/mol
Atomic weight of the parts:
Mg 24.3050 x 3 = 72.92
P 30.973762 x2 = 61.95
O 15.9994 x8 = 127.995
There are 262.855 grams in one mole, so
350.00 g x (262.855g/1 mole) = 1.33 moles Mg3(PO4)2
