The molar mass of Li->7g/mol
If 1mol of Li is 7g/mol
1.50mol of Li would be 10.5g/mol
Answer:
KOH
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
Element ratio of K.
K = 1
Because only potassium is present.
Element ratio of H₂O.
2 : 1
in water ratio of element is 2 : 1 because two hydrogen and one oxygen atom present.
Element ratio of KOH
1 : 1 : 1
in KOH elemental ratio is 1 : 1 : 1 because one potassium one hydrogen and one oxygen atom are present.
Element ratio of H₂.
2
Just two atoms of hydrogen are present.
C- Electron
A-Nucleus
B-Neutron
D-Protron

The substance that needs more energy to undergo an increase of 25°C will
have a higher specific heat, because energy depends directly on
specific heat.
Q = cm∆T
where c = specific heat of the substance,
m = mass
∆T = temperature difference </span>
