Answer: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Therefore, a high value of specific heat would mean that more heat is needed in order for the temperature to increase. The correct answer would be water since it has the highest specific heat of the choices given.

What is the mass of arsenic that is contained in a 50.0 g sample if the concentration is 5 ppm?
faltersainse [42]

<u>Answer:</u> The mass of arsenic found in the sample is 0.25 mg

<u>Explanation:</u>

ppm is the amount of solute (in milligrams) present in kilogram of a solvent. It is also known as parts-per million.

To calculate the ppm of oxygen in sea water, we use the equation:

\text{ppm}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6

Both the masses are in grams.

We are given:

Concentration of arsenic = 5 ppm

Mass of sample = 50 g

Putting values in above equation, we get:

5=\frac{\text{Mass of arsenic}}{50g}\times 10^6\\\\\text{Mass of arsenic}=\frac{5\times 50}{10^6}=0.00025g=0.25mg

<u>Conversion factor used:</u>  1 g = 1000 mg

Hence, the mass of arsenic found in the sample is 0.25 mg

What is the oxidation number sulfur in H2S?
Nikolay [14]

The oxidation number sulfur in H₂S is -2.

A compound's total number of oxidations must be zero.

The two hydrogen atoms in the chemical hydrogen sulfide, H₂S, each have an oxidation number of +1, making a total of +2. As a result, the compound's sulfur has an oxidation number of -2, and the total number of oxidations is 0.

Assume that the sulfur atom in H₂S has an oxidation number of x.

S be x.

Now,

2+x=0

⇒x=−2

<h3>What is oxidation number?</h3>

The total number of electrons that an atom either receives or loses in order to create a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.

Depending on whether we are taking into account the electronegativity of the atoms or not, these phrases can occasionally have a distinct meaning. Coordination chemistry commonly makes use of the phrase "oxidation number."

<h3>What distinguishes an oxidation number from an oxidation state?</h3>

In contrast to the oxidation state, which indicates how oxidised an atom is in a molecule, the oxidation number describes the charge that the core metal atom will retain once all ligands have been removed.
