Barium Cynanide is the compound
<span>We can use the heat
equation,
Q = mcΔT </span>
<span>
Where Q is the amount of energy transferred (J), m is
the mass of the substance (kg), c is the specific heat (J g</span>⁻¹ °C⁻<span>¹) and ΔT is the temperature
difference (°C).</span>
According to the given data,
Q = 300 J
m = 267 g
<span>
c = ?
ΔT = 12 °C</span>
By applying the
formula,
<span>300 J = 267 g x c x
12 °C
c = 0.0936 J g</span>⁻¹ °C⁻<span>¹
Hence, specific heat of the given substance is </span>0.0936 J g⁻¹ °C⁻¹.
The answer is C. If the Fours were all the way on the left it would make all of the zeros Significant figures.
Among the choices above, I think the statement that best describes an intensive property of matter is letter B which is " It depends on how a substance was formed." <span>Intensive properties are those property which does not depend upon the amount of substance present in the system. Such as refractive-index, density etc </span>
