Answer:
9.9 ml of 0.200M NH₄OH(aq)
Explanation:
3NH₄OH(Iaq) + FeCl₃(aq) => NH₄Cl(aq) + Fe(OH)₃(s)
?ml of 0.200M NH₄OH(aq) reacts completely with 12ml of 0.550M FeCl₃(aq)
1 x Molarity NH₄OH x Volume Am-OH Solution(L) = 2 x Molarity FeCl₃ x Volume FeCl₃ Solution
1(0.200M)(Vol Am-OH Soln) = 3(0.550M)(0.012L)
=> Vol Am-OH Soln = 3(0.550M)(0.012L)/1(0.200M) = 0.0099 Liter = 9.9 milliliters
Answer: add up to eight
Explanation: NaO as one bond as it takes only one and seven to make eight. Leaving NaO with three lone pairs
Answer: The new volume of the balloon will be 4.45L
Explanation: We will solve this question through the concept of Charles's law. The law states that the volume of a gas is directly proportional to the absolute temperature, assuming the quantity of gas and pressure remain constant.
Answer:
47900 cm
General Formulas and Concepts:
<u>Chemistry</u>
- Base 10 Decimal System
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
0.479 km
<u>Step 2: Identify Conversions</u>
1 km = 1000 m
1 m = 100 cm
<u>Step 3: Convert</u>
<u />
= 47900. cm
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
47900. cm ≈ 47900 cm
