Hey there! Hello!
Not sure if you still need the answer to this question, but I'd love to help out if you do.
So, the way to balance this equation is pretty simple. First, you need to keep in mind that molecules of hydrogen and oxygen do not come in single molecules, but in bonded pairs, represented by H2 and O2.

But, that's incorrect. The combination of 2 hydrogen molecules with 1 oxygen molecule yields water, but that leaves one oxygen molecule leftover. When broken down, this is how many of each molecule is on each side of the previously stated equation:
Left:
H: 2
O: 2
Right:
H: 2
O: 1
So we have to multiply H2O on the right side by 2 in order to get this:

Left:
H: 2
O: 2
Right:
H: 4
O: 2
The last step is to multiply H2 on the left by two to make it match up with the right side, balancing the equation:

Left:
H: 4
O: 2
Right:
H: 4
O: 2
That makes our equation balanced! I hope this helped you out, feel free to ask any additional questions if you need further clarification. :-)
CH2O2 formic acid I believe so
Explanation:
Adding a neutron will not affect the charge. The atom remains neutrally charged.
Since the charge of a neutron is neutral, or 0, the charge is not affected. Protons have a positive charge, whereas electrons have a negative charge. Since there are an equal number of protons and electrons, they cancel out.
Adding a neutron also increases the mass by 1. The mass of a neutron is 1 amu. The atomic mass is calculated by protons + neutrons.
Originally, the mass is 7 (because 3+4). The mass would now be 8 (because 3+5).
The correct answer would be: Atoms
I hope that this helps you!
Answer: ethylene glycol (molar mass = 62.07 g/mol)
Explanation:
Depression in freezing point :
Formula used for lowering in freezing point is,

or,

where,
= change in freezing point
= freezing point constant= 
m = molality
Given mass of solute = 0.807 g
Molar mass of solute=? g/mol
weight of solvent in kg= 11.6 g=0.0116 kg



Thus the solute is ethylene glycol which has same molecular mass as calculated, i.e 62.07 g/mol.
