How many grams of steam at 100 °C would be required to raise the temperature

Chemistry
1 answer:
Alex777 [14]2 years ago
3 0

The mass of steam required to raise the temperature of water is 3.5 g.

The given parameters;

  • <em>mass of the benzene, = 47.6</em>
  • <em>initial temperature of the benzene, = 5.5 ⁰C</em>
  • <em>final temperature of the benzene = 30 ⁰C</em>

The molar mass of Benzene = 78.11 g/mol

The molar mass of water = 18 g/mol

The number of moles of the Benzene is calculated as follows;

n = \frac{47.6}{78.11} = 0.61 \ mole

The mass of steam required is calculated as follows;

<em>heat lost by steam = heat absorbed by benzene</em>

<em />

\frac{m}{18} \times 40.7 \times 10^3 = 47.6(1.63)(30-5.5) \ + \ 0.61 \times 9.87 \times 10^3\\\\2261.11 m = 7921.61\\\\m = \frac{7921.61}{2261.11} \\\\m = 3.5 \ g

Thus, the mass of steam required to raise the temperature of water is 3.5 g.

How is primary selection different from secondary succession?
PIT_PIT [208]

Answer:

Explanation:

Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.

Hope this helped :)
