Answer:
Answer B is correct. Paying off your credit card bill will reduce the amount of debt you have and improve your credit score. Closing old credit cards only works if they are unused. As savings accounts are not included in a credit report, opening a new savings account will not have an effect, either negative or positive, on your credit score. Using up your credit limit will have the negative effect of lowering your credit score.

Answer:
0.153 moles of hydrogen.
B) Multiply 10 grams of Zn x (1 mol Zn/65.39 g)
Explanation:
Given data:
Mass of zinc = 10 g
Moles of hydrogen = ?
Solution:
Chemical equation:
Zn + 2HCl → ZnCl₂ + H₂
Number of moles of zinc:
Number of moles of zinc = mass/ molar mass
Number of moles of zinc = 10 g/ 65.4 g/mol
Number of moles of zinc = 0.153 mol
Now we will multiply the moles of Zn with hydrogen:
Zn : H₂
1 : 1
0.153 : 0.153
