Answer:
02 is a product
Explanation:
it doesnt take part in chemical reaction so its not reactant.02 doesnt alter rate of chemical reaction so it cannot be catalyst. it is gas it is not solid so it is a product.
To determine the empirical formula of the compound, we assume a basis of 100 g of this compound. We calculate as follows:
C = 68.75 g
H = 10.90 g
O = 20.35 g
We convert these mass to moles,
C = 68.75 g / 12.01 g/mol = 5.72 mol
H = 10.90 g / 1.01 g/mol = 10.79 mol
O = 20.35 g / 16 g/mol = 1.27 mol
C = 5.72 mol / 1.27 mol = 5
H = 10.79 mol / 1.27 mol = 8
O = 1.27 mol / 1.27 mol = 1

Temperature increase with altitude through the stratosphere because "<span>The ozone layer is found in the stratosphere".
Stratosphere is the second layer of the atmosphere of the Earth. 20% of the mass of the atmosphere is found in this layer.
</span><span>The temperature of the </span>stratosphere increases as the altitude increases due to the presence of the ozone layer in it as the ozone layer absorbs the ultraviolet radiations of the Sun which causes an increase in the temperature of this layer.
Answer:
C4H8
Explanation:
M(CF2) = M(C) + 2M(F) = 12.0 + 2*19.0 = 50.0 g/mol
M(unknown)/M(CF2) = 200.4 g/mol /50.0 g/mol = 4
So we need to take CF2 4 times.
