A Product is a new substance formed in a chemical reaction
Fossil fuel emissions can create acid rain, which in turn increases the pH of ocean water, harming the organisms in the ocean.<span />
Answer:
24 atoms of H or 1.4 x 10²⁵ hydrogen atoms
Explanation:
simple method
1 H₂O has atoms of hydrogen and 1 atom of oxygen
while 12H₂O will have 24 atoms of hydrogen and 12 atom of oxygen
by Avagadros number
molar mass of water H₂0=18.01528 g/mol
1 mole of H₂0 have 2 moles of Hydrogen
one mole of water= 6.02⋅10²³water molecules =1.2 x 10²⁴hydrogen atoms
12 mole of H₂O = 1.2 x 10²⁴ x 12= 1.4 x 10²⁵ hydrogen atoms
<u />
1.4 x 10²⁵ hydrogen atoms in 12 moles of H₂O
<u />
The first thing we need to remember is that:
We have 7.54g of CuCl2 so we need to express this amount in moles dividing by the molar mass of CuCl2.
This is:
And, also remember that 65.0mL equals 0.065L.
Now, replacing in the molarity equation:
Thus the answer is 0.862M.
Here you are! I hope it helps, and also for the ones I put a red ‘x’ it depends on how you round it.
