Salt is added to water. You speed up dissolving by stirring the salt into the water. Then your teacher challenges you to separat

e the salt from the water. You know that the salt and water have formed a solution and that the salt is distributed throughout the glass of water. What would be the BEST way to separate the salt and the water?
A) Collect the slat as it floats in the water.
B) Heat the solution to boiling and evaporate off the water.
C) Spin the solution at a high speed to separate out the salt.
D) Pour the solution through filter paper to filter out the salt.

The chemistry of living things and living systems created a new combined field in science known as
Anastasy [175]

Answer:

Biochemistry.

Explanation:

Biochemistry can be defined as the branch of science that deals with the study of the chemical processes, physio-chemical reactions and various substances that are found in living organisms such as animals, plants, and microorganisms.

Simply stated, biochemistry is a field in science that combines both the elements of biology and chemistry in order to study living organisms.

For example, all living organisms have the ability to engage in respiration in other to breathe in oxygen to stay alive. Thus, biochemistry helps us to understand respiration as a physio-chemical process that converts glucose into a form of energy (Adenosine Triphosphate-ATP) that is beneficial to all living organisms.

Hence, the chemistry of living things and living systems created a new combined field in science known as biochemistry.

In an exothermic reaction, chlorine reacts with 2.0200g of hydrogen to form 72.926g of hydrogen chloride gas. how many grams of
Artemon [7]

Answer : 70.906 grams of chlorine reacted with hydrogen

Explanation :

Step 1 : Write balanced chemical equation.

The balanced chemical equation for the reaction between hydrogen and chlorine gas is given below.

H_{2} (g) + Cl_{2} (g) \rightarrow 2HCl(g)

Step 2 : Find moles of H₂ gas.

The moles of H₂ can be found as

mole = \frac{grams}{MolarMass}

We have 2.0200 g of H₂ and molar mass of H₂ is 2.02 g/mol.

Let us plug in these values to find moles of H₂.

mole =\frac{2.0200g}{2.02g/mol} = 1 mol

We have 1 mol of H₂.

Step 3 : Find moles of Cl₂ using mole ratio.

The mole ratio of H₂ and Cl₂ is 1 : 1.

The moles of Cl₂ can be calculated as

1 mol H_{2} \times\frac{1 mol Cl_{2}}{1 mol H_{2}} = 1 mol Cl_{2}

Step 4 : Find grams of Cl₂.

Molar mass of Cl₂ gas is 70.096 g/mol

Mass of Cl₂ = 1 mol Cl_{2} \times\frac{70.906g}{mol} = 70.906 g

We have 70.906 grams of Cl₂
