2.34 moles titanium x (6.022 x 10^23)/1 mole titanium = 1.41 x 10^24
The balanced chemical reaction is:
<span>2H2O= 2H2 + O2
</span>
We are given the amount of oxygen to be produced in the reaction. The starting point for the calculations will be this amount.
50 g ( 1 mol O2 / 32 g O2 ) ( 2 mol H2O / 1 mol O2 ) ( 18.01 g H2O / 1 mol H2O) = 56.28 g of H2O is needed.
Therefore, the correct answer is the last option.
Answer:
I think the answer is d. Each substance in a mixture keeps most of its characteristic properties.
Answer:
approx 2.45g
Explanation:
2HCl + Na2SO4 → 2NaCl + H2SO4
2 : 1 : 2 : 1
0.05 0.025 (moles)
⇒ mH2SO4 = 0.025 × 98 = 2.45 g
