Answer:
376.56
Explanation:
using the formula q=mcΔT, where m=15g, C=4.18J/g°C and ΔT=6.0°C
Answer:
one mole of HgO will give one mole of Hg.
Explanation:
Given data:
Moles of HgO = 1 mol
Moles of Hg = ?
Solution:
Chemical equation:
2HgO → 2Hg + O₂
Now we will compare the moles of Hg with HgO from balance chemical equation.
HgO : Hg
2 : 2
1 : 2/2×1 = 1 mol
So, one mole of HgO will give one mole of Hg.
Simple machines help reduce the amount of work being done, as they help by using a simple function. One disadvantage is that they do not help completely.

➷ It would depend on whether they would create an endothermic reaction or exothermic. For a hot pack, the chemicals would need to release energy (heat). However, a cold pack would need chemicals that need to draw heat from the surroundings to produce a cool sensation.
