Answer:

The mass of N a H C O 3 present is 2.431 g

Explanation:

The sample contains 57.2 % N a H C O 3 by mass.

To find the mass of N a H C O 3 in the sample, we need to find what the equivalent of 57.2 %.

Mass of N a H C O 3 = Percentage Composition * Mass of sample

Mass of N a H C O 3 = 57.2 / 100 * 4.25

Mass of N a H C O 3 = 2.431 g

The mass of N a H C O 3 present is 2.431 g

Why are metals malleable,ductile,and good conductors

9966 [12]

The energy is transferred throughout the rest of the metal by the moving electrons. Metals are described as
malleable (can be beaten into sheets) and ductile (can be pulled out into wires). This is because of the ability of the atoms to roll over each other into new positions without breaking the metallic bond.

Answer:

$6.25\times 10^{-6}$ is the value of the equilibrium constant at this temperature.

Explanation:

Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power equal to their stoichiometric ratios. It is expressed as $K_{p}$
