Try this solution:
if given m=0.15 kg; t₁=20 °C; t₂=100 °C; c=4190 J/(kg*C); q=226*10⁴ J/kg., then
Q=Q₁+Q₂,
where Q₁=cm(t₂-t₁) and Q₂=q*m.
Finally,
Q=cm(t₂-t₁)+qm;
Q=4190*0.15*80+2240000*0.15=386280 J=<u>386.28 kJ</u>.
Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. ... Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.

I think the correct answer from the choices listed above is the third option. The magnetic quantum number of an electron (m) designates the orientation in space of the orbital (electron cloud). <span>This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell. </span>
