Answer:
Explanation:
Divide the mass by the density and the units of grams will cancel so youll end up with mL.
(52.757g)/(12.5g/mL) = 4.2mL
A carbon atom is capable of bonding with 4 atoms including carbon itself. So, when there is a double bond between two carbon atoms, each carbon atom has an extra 2 unoccupied bonds. <em>Thus, each carbon atom in a C=C bond is capable of bonding with two other hydrogen atoms.</em>
The cell is the most basic unit of <u><em>ALL</em></u> living things.

Answer:
I am pretty sure it is the first one: Melting, cooling and hardening
Explanation:
igneous rocks are made of molten lava and then they cool down and harden form into a rock. PLEASE correct me if i am wrong.
Answer:
6.52moles of H2O
Explanation:
First, let us calculate the number of moles of O2 containing 1.96x10^24 molecules. This is illustrated below:
1mole of O2 contains 6.02x10^23 molecules.
Therefore Xmol of O2 contain 1.96x10^24 molecules i.e
Xmol of O2 = 1.96x10^24/6.02x10^23 = 3.26moles
Now let us generate a balanced equation for the formation of water. This is illustrated below:
2H2 + O2 —> 2H2O
From the equation,
1mole of O2 produced 2moles of H2O.
Therefore, 3.26moles of O2 will produce = 3.26 x 2 = 6.52moles of H2O
