Answer:
16 g Ag
General Formulas and Concepts:
<u>Chemistry - Stoichiometry</u>
- Using Dimensional Analysis
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
[RxN] Cu (s) + AgNO₃ (aq) → CuNO₃ (aq) + Ag (s)
[Given] 25 g AgNO₃
<u>Step 2: Identify Conversions</u>
[RxN] 1 mol AgNO₃ = 1 mol Ag
Molar Mass of Ag - 107.87 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of AgNO₃ - 107.87 + 14.01 + 3(16.00) = 169.88 g/mol
<u>Step 3: Stoichiometry</u>
<u /> = 15.8744 g Ag
<u>Step 4: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules and round.</em>
15.8744 g Ag ≈ 16 g Ag
Because you always take the second number from the group number and it gives you the charge amount.
The answer is D. milligram. Millimeter is for a length, Millisecond is for time, Mililiter is for water.
Answer:
On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.
