Answer:

Endothermic and Exothermic Reactions

Many familiar chemical reactions, such as the burning of coal, rusting and exploding gunpowder, give off heat; chemists call these reactions exothermic. Because reactions liberate heat, they increase the ambient temperature.

How many moles of LiOH are needed to react completely with 25.5 g of CO2

LekaFEV [45]

Answer:

3.18 mol

Explanation:

$2LiOH+CO_{2}-> Li_{2}CO_{3} +H_{2}O$

n(CO2) = mass/ Mr.

= 25.5 / 16

= 1.59 mol

As per the equation above,

n(LiOH) : n(CO2)

2 : 1

∴ 3.18 : 1.59
