when a substance undergoes a change of color it is an indication that it was chemical
They release spores into the air, often carried by the wind. They allow spore bearing plants to replicate themselves in a form of cloning.
<h2>Steps:</h2>
- Remember that Density = mass/volume, or D = m/v
So firstly, we have to find the volume of the rock. To do this, we need to subtract the volume of water A from the volume of the water B. In this case:
- Water A = 30 mL
- Water B = 40 mL
- 40 mL - 30 mL = 10 mL
<u>The volume of the rock is 10 mL.</u>
Now that we have the volume, we can plug that and the density of the rock into the density equation to solve for the mass.

For this, multiply both sides by 10:

<h2>Answer:</h2>
<u>Rounding to the tenths place, the mass of the rock is 36.8 g, or C.</u>
Answer:
NaOH or sodium Hydroxide
Explanation:
The chief active ingredient in most over cleaners is NaOH or sodium hydroxide, also known as lye. Other common ingredients include butane (C4H10), Monoethanolamine (HOCH2CH2NH2) and Diethylene glycol monobutyl ether (C8H18O3).
