Answer:
75.12 J
Explanation:
Applying,
Q = CΔT................ equation 1
Where Q = amount of heat, C = Heat capacity, ΔT = temperature rise.
From the question,
Given: C = 62.6 J/K, ΔT = 1.20°C
Substitute these values into equation 1
Q = 62.6(1.20)
Q = 75.12 J
Hence the amount of heat it absorbed is 75.12 J
The term that identifies the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius is Specific heat capacity.
<h3>
What is specific heat capacity?</h3>
Specific heat capacity is the quantity of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius. The unit of specific heat capacity is joule per gram per degree Celsius (J/g⁰C).
<h3>Difference between
heat capacity and
specific heat capacity</h3>
Specific heat capacity is heat required to raise the temperature of a unit mass of a substance while heat capacity is the quantity of heat required to raise the temperature an entire mass of a substance.
Heat capacity is measure in Joules (J) while specific heat capacity is measured in joule per gram per degree Celsius (J/g⁰C).
Thus, the term that identifies the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius is Specific heat capacity.

Reaction of combustion of butane is a as follows:
2 C₄H₁₀ + 13 O₂ --> 8 CO₂ + 10 H₂O:
As it can be seen from the equation that 2 mole of butane produce= 8 mole of butane produce
1 mole of butane produce= 4 mole of butane produce
1.60 g of butane=
= 0.027 mole of butane
0.027 mole of butane =
= 0.108 mole of CO₂.
Using ideal gas equation,
Here,
P denotes pressure
V denotes volume
n denotes number of moles of gas
R denotes gas constant
T denotes temperature
The values at STP will be:
P=1 atm
T=23+273 K = 296 K
R=0.0821 atm L mol ⁻¹
Number of moles of gas, n= 0.018
Putting all the values in the above equation,
V= 2.62 L
So the volume will be 2.62 L
Answer: Calcium
Explanation: The chemical element Calcium (Ca), atomic number 20, is the fifth element and the third most abundant <u><em>metal</em></u> in the earth's crust. The metal is trimorphic, harder than sodium, but softer than aluminium.
