Answer:

90g of Ca(OH)2

Explanation:

2HCl + Ca(OH)2 —> CaCl2 + 2H20

Molar Mass of Ca(OH)2 = 40 + 2( 16 + 1) = 40 + 2(17) = 40 + 34 = 74g/mol

Molar Mass of CaCl2 = 40 + (2 x 3.5) = 40 + 71 = 111g/mol

From the equation,

74g of Ca(OH)2 produced 111g of CaCl2.

Therefore, Xg of Ca(OH)2 will produce 135g of CaCl2 i.e

Xg of Ca(OH)2 = (74 x 135) / 111 = 90g.

Therefore, 90g of Ca(OH)2 are required to produce 135g of CaCl2

What is the final temperature of a 27.2-gram wooden block that starts at 23.4°C and loses 759 joules of energy? The specific hea
sattari [20]

T = final temperature  of the block

T₀ = initial temperature of the block = 23.4 °C

Q = energy lost  from the wooden block = - 759 J

c = specific heat capacity of wood = 1.716 J/(g  °C)

m = mass of the wooden block = 27.2 g

Heat lost from the block is given as

Q = m c (T - T₀)

inserting the values

- 759 = (27.2) (1.716) (T - 23.4)

T = 7.1 °C
