<u>Given</u> :
- Amount = 20 kg
- Heat energy absorbed = 237,000 J
- Temperature change = 15 °C
<u>Formula applied</u> :

- Q = absorbed heat
- m = mass
- c = specific heat capacity
- ΔT = temperature change
Let's solve for c !
⇒ 237,000 = 20 × c × 15
⇒ c = 237,000 ÷ 300
⇒ 
∴ The specific heat capacity of granite is <u>790 J kg⁻¹ K⁻¹</u>.
Water can only dissolve inorganic compounds is false
After 4-6 months but i'm happy for you
When [HClO]= 0.01 M & [ClO]^- = 0.03M & NaOH = 0.003 mol and
Ka = 3.5 x 10^-8
and the equation is:
HClO + NaOH → Na^+ + ClO^-
initial 0.01 0.003 0.03 0.03
-0.003 - 0.003 +0.003 + 0.003
Final 0.007 0 0.033 0.033
We can get the PH from this formula:
PH = Pka + ㏒[conjugent base/weak acid]
PH = -㏒Ka + ㏒[Na]/[HClO]
= - ㏒ 3.5x10^-8 + ㏒(0.033/0.007)
= 8.13
Answer:
Steam always has more thermal energy than ice.
