A 0.2 M solution of NaCl contains ________ g of NaCl in 1 l of ________.
Maksim231197 [3]

Answer:

11.7 g in 1 L of water.

Explanation:

Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.

It is defined as mol/ L (number of moles per litre).

0,2 M means we have 0,2 mol/ L

In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol

\frac{1 mol NaCl}{58.443 g} = \frac{0.2 mol}{X g}

X= \frac{(0.2 mol x 58.433 g}{1 mol}

X= 11.69 g

The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.

Describe an environmental factor that could influence natural selection and decrease genetic diversity
pashok25 [27]

Answer:

Usually, Populations have a genetic variation among individuals, which is important to the population's ability to survive in different situations that have an effect on the natural selection. There are different factors which can increase or decrease the genetic diversity, and influencing natural selection.

These factors include an environmental factor, one of the major factors, which may cause changes in the genetic variation of a population and influence the natural selection. A famous and important example of environmental factors affecting natural selection was during the Industrial Revolution, when many more grey moths made up the moth population.

This was so that they could blend in with the soot from factories to avoid predators.

Based on the temperature data in the table which chemical reaction should the students use for their food carrier design
Sladkaya [172]

Answer:

Reaction 1

Explanation:

Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.
