When iron metal reacts with sulfuric acid, it produces iron (III) sulfate and hydrogen gas. Balance the equation: Fe + H2SO4 → F
gavmur [86]
<h3>Answer:</h3>
  1. Balanced Equation; 2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
  2. Why balance?: To obey the law of conservation of mass
  3. Subscripts can not be changed, since they show the actual number of atoms of each element in a compound.
<h3>Explanation:</h3>
  • The balanced equation for the reaction between the iron metal and sulfuric acid to produces iron (III) sulfate and hydrogen gas is given by;

2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂

  • Balancing chemical equations ensures that they obey the law of conservation of mass which requires the mass of reactants and the mass of products to be equal.
  • Balancing is done by putting coefficients on reactants and products while not affecting the subscripts as subscripts show the actual number of atoms of an element in a compound.

In a laboratory, bunsen burner is used to increase the temperature of lime from 10 °C to 50 °C with the thermal energy of 80000
galina1969 [7]

Answer:

c = 100 J/g.°C

Explanation:

Given data:

Mass of lime = 20 g

Heat absorbed = 80,000 J

Initial temperature = 10°C

Final temperature = 50°C

Specific heat capacity of lime = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 50°C - 10°C

ΔT = 40°C

80,000 J = 20 g×c×40°C

80,000 J = 800°C×c

c = 80,000 J /800g.°C

c = 100 J/g.°C
