It's kinda like a name!
3531.23 J is the energy used to heat tin when 229.2 g of tin was heated from 46.3 to 115.7°C.
<h3>What is specific heat capacity?</h3>
The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases by 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
Q=mcΔT
Give data:
m=229.2 g
c=0.222 J/g x °C
ΔT=115.7°C - 46.3°C
ΔT= 69.4 °C
Putting value in the equation:
Q=mcΔT
Q=229.2 g x 0.222 J/g°C x 69.4 °C
Q= 3531.23 J
Hence, 3531.23 J is the energy used to heat tin.

I think the correct answer from the list of choices above is option B. <span>The chemical combination of two or more different atoms in fixed amounts is called a compound. There are two type of compounds namely the ionic and covalent compounds.</span>
Answer: from multipliers of substances and real amount of moles you get an equation
For x = amount of ammonia in moles. X/4 = 2.75/6 and x = 11/6 = 1.83 mol
Explanation:
Physical Properties<span>: </span>Physical properties<span> can be observed or measured without changing the composition of matter. </span>Physical properties<span> are used to observe and describe matter. so physical changes are the change in temperature of the land and the evaporation of water and change humidity of the air. chemical change is the ripening of the orange</span>
