What is the relationship between the internal energy of a substance and its particle movement?

Chemistry
1 answer:
ss7ja [257]3 years ago
6 0

Answer: The closeness, arrangement and motion of the particles in a substance change when it changes state. Materials are a store of internal energy , due to the motion of particles and the chemical bonds between them. When a substance is heated, its internal energy increases: the movement of its particles increases.

Write the net ionic reaction that occurs upon the addition of hno3 to a solution which contains methylamine (ch3nh2) and methyla
ra1l [238]
Hello!

First, HNO₃ dissociates in the following way:

HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)

Next, there is a neutralization reaction with Methylamine:

H⁺(aq) + CH₃NH₂(aq) → CH₃NH₃⁺(aq)

Finally, the formed methylammonium ion weakly dissociates in the following way:

CH₃NH₃⁺(aq) + H₂O(l)  ⇄ H₃O⁺(aq) + CH₃NH₂ (aq)

From this sequence of reactions, we can see that the resulting solution would be slightly more acidic than the initial one, as the buffer solution resists the addition of strong acid.

Have a nice day!

What is the precent yield if the actual yield is 25g and 100g should have formed?
11Alexandr11 [23.1K]

Answer:

Percent yield is 25%

Explanation:

Information given is

Actual yield is 25 g

But the yield should be 100 g

The percent yield is defined as the ratio of the actual yield and the predicted yield it means that out of the predicted yield what percentage of the actual yield is obtained

∴ Percent yield = (Actual yield ÷ Predicted yield) ×  100

In case of the given problem the percent yield will be

(25÷100) × 100 = 25%

∴ Percent yield = 25%
