Question

pls help me its urgent​

Answer 1

Step-by-step explanation:

Given that:-

$Length \: of \: the \: wall = 10m = 1000 cm \\ Height \: of \: the \: wall = 4cm \\ Width \: of \: the \: wall \: = 24cm \\ Volume \: of \: the \: wall =Length × Width × Height \\ = 1000 \times 24 \times 49 \\ = 96000 {cm}^{3} \\ \\ Volume \: of \: each \: brick =24 \times 10 \times 8 \\ = 1920 {cm}^{3} \\ \\ No. \: of \: bricks \: required = \frac{Volume \: of \: the \: wall}{Volume \: of \: each \: brick} \\ = \frac{96000}{1920} \\ = 50 \\ \\ Since, the \: brick \: is \: to \: be \: taken \: as \: a \: whole, so \: to \: build \: the \: wall \: 50 \: bricks \: are \: required.$

Answer 2

Step-by-step explanation:

A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Precipitation reactions can help determine the presence of various ions in solution.
