Answer:
500 mL
Explanation:
Step 1: Find conversions
1 mL = 0.0338 oz
Step 2: Use Dimensional Analysis
= 500 mL
Explanation:
If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.
Substance 1,
Mass, m = 450 g, Volume, V = 90 mL
Density = mass/volume
So,

It will sink.
Substance 2,
Mass, m = 35 g, Volume, V = 70 mL
Density = mass/volume
So,

It will float.
Substance 3,
Mass, m = 24 g, Volume, V = 12 mL
Density = mass/volume
So,

It will sink.
Speed ; the rate at which someone or something is able to move or operate.
Motion; the action or process of moving or being moved
It’s decomposition. The compound is being broken apart into two different things aka decomposing.
Answer:
B.
Explanation:
When water separates into hydrogen and oxygen gas, a decomposition reaction is taking place (one substance breaking apart or breaking down into two or more substances).
The law of conservation of mass tells us that mass is not created or destroyed during a chemical reaction, so the total mass will remain the same. This is supported by the diagram on the page, which shows that in the reactants, there are four hydrogen atoms and two oxygen atoms, and this amount is the same on the product side.
