Answer:
25.11 g.
Explanation:
- It is clear from the balanced equation:
<em>Ag₂O + 2HCl → 2AgCl + H₂O.</em>
<em></em>
that 1.0 mole of Ag₂O reacts with 2.0 moles of HCl to produce 2.0 mole of AgCl and 1.0 moles of H₂O.
- 7.8 g of HCl reacts with excess Ag₂O. To calculate the no. of grams of Ag₂O that reacted, we should calculate the no. of moles of HCl:
<em>no. of moles of HCl = mass/atomic mass</em> = (7.9 g)/(36.46 g/mol) = <em>0.2167 mol.</em>
- From the balanced equation; every 1.0 mol of Ag₂O reacts with 2 moles of HCl.
∴ 0.2167 mol of HCl will react with (0.2617 mol / 2 = 0.1083 mol) of Ag₂O.
<em>∴ The mass of reacted Ag₂O = no. of moles x molar mas</em>s = (0.1083 mol)(231.735 g/mol) = <em>25.11 g.</em>
Answer:
Terms in this set (31) A reaction that involves the transfer of electrons from one molecule to another is referred to as. a redox reaction. During an oxidation reaction, the donor molecule loses an electron and becomes oxidized.

Answer:
40°C.
Explanation:
A calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water through 1 °C. In the same way, a kcal would be defined as the amount of energy needed to raise the temperature of 1 kilogram of water through 1 °C.
Based on this definition, 100kcal will increase the emperature of the water in:
100kcal / 2,5kg = <em>40°C</em>

Answer: C. Z is an intermediate.
Explanation: The given reaction is 
And the rate equation is rate = k [X_2][Y]
From this, we can imply that either the concentration of Z is very small in comparison tot he other reactants or the reactant Z is an intermediate which is available only for the given small amount of time.
There can be various steps in the mechanism for the proposed reaction and Z can also react in any of the steps. It is not necessary that it should react in a step other than the rate determining step.
This might be possible that the activation energy for Z to react is very low But since it has made a new kind of product that is XZ, then the former cannot be true.
Answer:
<h2>1.806 × 10²⁴ molecules</h2>
Explanation:
The number of molecules of silver nitrite can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 3 × 6.02 × 10²³
We have the final answer as
<h3>1.806 × 10²⁴ molecules</h3>
Hope this helps you
