Vinegar is a liquid consisting of about 5–20% acetic acid(CH3COOH),

Sodium hydroxide is a strong base. In concentrated form its pH can go up to somewhere in the region of 13-14

The salts produced by the action of ammonia on acids are known as the ammonium salts and all contain the ammoniumion (NH4+). Although ammonia is well known as a weak base, it can also act as an extremely weak acid.

Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral. If the medium is ethanol (or any other solvent), water can be acidic, neutral or basic

What is the percent composition of hydrogen if a sample is found to contain 7 grams of hydrogen, 32 grams of nitrogen, and 7 gra

nata0808 [166]

Answer: The percent composition of hydrogen in the sample is 15.22 %

Explanation:

We are given:

Mass of hydrogen = 7 grams

Mass of nitrogen = 32 grams

Mass of carbon = 7 grams

Total mass of the sample = 7 + 32 + 7 = 46 grams

To calculate the percentage composition of hydrogen in sample, we use the equation:

$\%\text{ composition of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of sample}}\times 100$

Mass of sample = 46 g

Mass of hydrogen = 7 g

Putting values in above equation, we get:

$\%\text{ composition of hydrogen}=\frac{7g}{46g}\times 100=15.22\%$

Hence, the percent composition of hydrogen in the sample is 15.22 %

Determine the enthalpy of solution for a solid with δh values as described in each scenario.

IrinaVladis [17]

Answer : To determine enthalpy of solution for a solid with δH values.

One can use the equation as H (reaction) = H (products) - H (reactants)

If δH values are known one can simply substitute them in the above equation and get the enthalpy of the required solution.
