Answer:
2Rb(s) + Sr^+(aq) → 2Rb^+ (aq) + Sr(s)
Explanation:
Rubidium has a more negative reduction potential (-2.98 V) compared to strontium (-2.89 V).
Hence, in a redox reaction involving rubidium and strontium, rubidium will be oxidized while strontium is reduced.
The balanced redox reaction equation is obtained from;
Oxidation half equation;
2Rb(s) ---->2Rb^+(aq) + 2e
Reduction half equation;
Sr^2+(aq) + 2e ----> Sr(s)
Overall reaction equation;
2Rb(s) + Sr^+(aq) → 2Rb^+ (aq) + Sr(s)

Answer:
D. 27.099 x 10²³.
Explanation:
- It is known that every 1.0 mole of an atom contains Avogadro's no. (6.022 x 10²³) atoms.
<em>So, 4.5 mol of Hg will contain:</em>
(4.5 mol)(6.022 x 10²³) = 27.099 x 10²³ atoms.
<em>So, the right choice is: D. 27.099 x 10²³.</em>
Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>

8:24 = 0.333(3) pints is one percent
0.333(3)* 100=33.333(3) pints will be 24% mixture with the water
33.3333-8=25.333 pints of water is required for producing 24% mixture
25.3333 pints of pure water and 8 pints of juce.
