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;
The mass of steam required is calculated as follows;
<em>heat lost by steam = heat absorbed by benzene</em>
<em />
Thus, the mass of steam required to raise the temperature of water is 3.5 g.

Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property. It is a chemical property.
C I’m pretty sure. I can explain just lmk
The HNO3 is considered to be a Bronsted - Lowry acid, when this substance 'HNO3', will donate a proton, then it will form another substance. It will form two substances when the proton is donated in the water molecule. The two substances that will be formed is a nitrate iron and a hydronium ion.
The only exception of calculating mechanical advantage is by multiplying resistance force by effort force. For example, in calculating the mechanical advantage of a lever, we consider its output and input forces. The equation would now be as follows:
Mechanical advantage = output force / input force
