The answer is (2) gains 12 moles of electrons. In every chemical reaction, the electrons will not be destroyed or created, it will only transfer. So the Al loses electrons, the oxygen needs to gain the same amount of electrons.

Convert 732.0 mmHg to atm
enot [183]

Answer:

The answer is

<h2>0.95 atm</h2>

Explanation:

To solve the question we use the following conversion

That's

1 mmHg \cong 0.0013 atm

So we have

If 1 mmHg \cong 0.0013 atm

Then 732 mmHg will be

732 × 0.0013 atm

We have the final answer as

<h3>0.95 atm</h3>

Hope this helps you

2 grams of a substance was dissolved in 75.0 g of water resulting in a temperature decrease from 23.1 ⁰C to 18.7 ⁰C. The specifi
RUDIKE [14]
<h3>Answer:</h3>

1379.4 Joules

<h3>Explanation:</h3>
  • The quantity of heat is calculated multiplying the mass of a substance by heat capacity and the change in temperature.

Therefore;

Quantity of heat = Mass × specific heat capacity × Change in temperature

Q = mcΔT

In this case;

The substance dissolved in water gained heat while water lost heat energy.

Thus, Heat gained by the substance = heat lost by water

Heat associated with the water  

Mass of water = 75 g

Change in temperature = 4.4°C

Specific heat capacity =  4.18 J/g·⁰C

Heat = mcΔT

        = 75 g × 4.18 J/g·⁰C × 4.4 °C

        =1379.4 Joules
