Answer:
The answer is
<h2>0.34 cm³</h2>
Explanation:
The denisty of a substance can be found by using the formula
<h3>
![Density(\rho) = \frac{mass}{volume}](https://tex.z-dn.net/?f=Density%28%5Crho%29%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20)
</h3>
Making volume the subject we have
<h3>
![volume = \frac{mass}{Density}](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7BDensity%7D%20)
</h3>
From the question
mass = 4.62 g
Density = 13.5 g/cm³
Substitute the values into the above formula and solve for the volume
That's
<h3>
![volume = \frac{4.62}{13.5}](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B4.62%7D%7B13.5%7D%20)
</h3>
= 0.34222……
We have the final answer as
<h3>0.34 cm³</h3>

Answer: D
Explanation: cells are alive
Answer:
A. Precipitation
Explanation:
<u>Precipitation</u> is any form of water that falls to the Earth from the sky.
Examples of Precipitation are:
Answer:
Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces.
Explanation:
Different sources of energy are required in the formation of rocks. A source of energy like the sun is vital in the facilitation of processes pertaining to rock formation that occur on the surface of the earth. Some of these processes include; erosion and weathering.
The internal heat energy from the earth also facilitate rock formation processes that occur at the core of the earth. Some of them include; melting and subduction. So, energy from different sources result to different types of rocks.
The molarity of a solution equals to the mole number of the solute/the volume of the solution. For NH4Br, we know that the mole mass is 98. So the molarity is (14/98) mol /0.15 L=0.95 mol/L.
