I'm really sorry but I am not from India.
Answer:
1,620 J.
Explanation:
- The amount of heat added to a substance (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat released from ethanol cooling,
m is the mass of ethanol (m = 60.0 g),
c is the specific heat of ethanol in the liquid phase, since the T is cooled below the boiling point and above the melting point (c = 1.0 J/g °C),
ΔT is the temperature difference (final T - initial T) (ΔT = 43.0 °C – 70.0 °C = - 27.0 °C).
<em>∴ Q = m.c.ΔT</em> = (60.0 g)(1.0 J/g °C)(- 27.0 °C) = - 1620 J.
<em>The system releases 1620 J.</em>

Equation:
N2(g) + 3H2(g) → 2NH3(g)
Check for limiting reactant
Molar mass N2 = 28g/mol
mol N2 in 31,500g = 31,500/28 = 1,125 mol N2
This will require 1,125*3 = 3,375 mol H2
Molar mass H2 = 2g/mol
Mol H2 in 5,220g = 5,220/2 = 2,610 mol H2
The H2 is limiting
From the equation:
3 mol H2 will produce 2mol NH3
2610 mol H2 will produce 2610*2/3 = 1,740 mol NH3
Molar mass NH3 = 17g/mol
Mass of 1740 mol NH3 = 1740*17 = 29,580g NH3 produced
Mass of NH3 produced = 29.6kg</span>
Answer:
Lewis acid is a substance that donates a lone-pair of electrons.
Explanation:
What is said in the statement corresponds to a Lewis base, not an acid. For example, NH3 is a Lewis base, since it is capable of donating its pair of electrons. Trimethylborane (Me3B) is a Lewis acid, since it is capable of accepting a solitary pair.
Answer:
C7H603 + CH3OH --> C8H803 + H2O
Balanced equation with corresponding stoichiometric numbers.
Explanation:
the salicylic acid, also called aspirin, when reacting with methanol produced an irreversible reaction giving methyl salicylate and water
