During the phase change from solid ice to liquid water, which bonds/forces are being weakened?

1 answer:

5 0

INTERmolecular forces (such as dipoles and London dispersion forces).

The actually compound isn't changing (it's still H2O in solid or liquid form), so INTRAmolecular bonds aren't being affected. It's just the strength of attraction between separate molecules that is weakening.

Identify the reversible chemical reaction below. A. reactants=>products B. Products <=> reactants C. products => rea

Korvikt [17]

Answer:

Its B

Explanation:

Products <=> reactants; products can go back to reactant and reactants can form products, depending on the equilibrium position.

The equilibrium position, if it is on the left, and much of the product is formed. If the equilibrium position is not the right, then its the vice versa The equilibrium position is determined by ;

Temperature

If the reaction is endothermic, it will be favoured by increase in temperature and equilibrium position will shift to the right ( reactants )

If the reaction is exothermic, its the vice versa

NOTE: Only temperature affects the equilibrium position

A 49.48-mL sample of an ammonia solution is analyzed by titration with HCl. It took 38.73 mL of 0.0952 M HCl to titrate the ammo

Kryger [21]

Answer:

M₂ = 0.0745 M

Explanation:

In case of titration , the following formula can be used -

M₁V₁ = M₂V₂

where ,

M₁ = concentration of acid ,

V₁ = volume of acid ,

M₂ = concentration of base,

V₂ = volume of base .

from , the question ,

M₁ = 0.0952 M

V₁ = 38.73 mL

M₂ = ?

V₂ = 49.48 mL

Using the above formula , the molarity of ammonia , can be calculated as ,

M₁V₁ = M₂V₂

0.0952 M * 38.73 mL = M₂* 49.48 mL

M₂ = 0.0745 M

Calculate the answer. Express it in scientific notation. All answers should have the correct number of significant figures.

artcher [175]

To express the answer of (6.93 x 10¹) (2.0 x 10-4) in scientific notation, it should be 1.4 x 10^-2. To multiply two numbers expressed in scientific notation, simply multiply the numbers out front and add the exponents. I hope it helps.
