What happens if a solid changes the state of substance to liquid?

It would had to have melted in order to change the properties from a solid into a liquid. It also depends on the type of solid wheither a chemical or a ice cube. If it was a ice cube if would dilutte the liquid solution and changes the taste ot texture (feel) if it was a chemical the properties could change the liquid into a solid only depending on th type of chemical. EX..Liquid Nitrogen and a piece of raw chiken the outcome after putting the chicken in the nitrogen would be frozen. Because the chemical Nitrogen freezes the particles which makes the chicken frozen.

What is the concentration of NaCl in a solution if titration of 15.00 mL of the solution with 0.2503 M AgNO3 requires 20.22 mL o

Nina [5.8K]

Answer:

The concentration of NaCl = 0.3374 M

Explanation:

Given :

Molarity of AgNO₃ = 0.2503 M

Volume of AgNO₃ = 20.22 mL

The conversion of mL into L is shown below:

$1 mL= 10^{-3} L$

Thus, volume of the solution = 20.22×10⁻³ L

Molarity of a solution is the number of moles of solute present in 1 L of the solution.

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

The formula can be written for the calculation of moles as:

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

Thus,

$Moles\ of\ AgNO_3 =Molarity \times {Volume\ of\ the\ solution}$

$Moles\ of\ AgNO_3 =0.2503 \times {20.22\times 10^{-3}}\ moles$

$Moles\ of\ AgNO_3 = 5.0611 \times 10^{-3} moles$

The chemical reaction taking place:

$AgNO_3_(aq) + NaCl_(aq) \rightarrow AgCl_(s) + NaNO_3_(aq)$

According to reaction stoichiometry:

1 mole of AgNO₃ reacts with 1 mole of NaCl

Thus,

5.0611×10⁻³ moles of AgNO₃ reacts with 5.0611×10⁻³ moles of NaCl

Thus, moles of NaCl required = 5.0611×10⁻³ moles

Volume of NaCl required = 15.00 mL

The conversion of mL into L is shown below:

$1 mL= 10^{-3} L$

Thus, volume of the solution = 15.00×10⁻³ L

Applying in the formula of molarity as:

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

$Molarity\ of\ NaCl=\frac{5.0611\times 10^{-3}}{15.00\times 10^{-3}}$

$Molarity\ of\ NaCl= 0.3374 M$

Thus, the concentration of NaCl = 0.3374 M

The muscles on the run in transform chemical potential energy into_____

LekaFEV [45]

Mechanical Energy

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

Explanation:

Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.

In the muscles, to have movement, the chemical bonds in ATP is broken to enable the sliding action of the myosin and actin fibres of a sarcomere (the basic unit of muscle). This sliding action is responsible for contraction of muscle. The coordinated contractions and relaxations of sarcomeres on muscles result in movement which translates to mechanical energy.

This process is never 100% efficient with some energy lost as heat energy.
