First part is polar, second part is non-polar. Use the saying "like dissolves like". Substances that are alike in polarity are more likely to dissolve one another.

Answer : Polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes.

Explanation :

According to the concept of “Like dissolves like”, the polar solvents dissolve polar solutes, and non-polar solvents dissolve non-polar solutes.

For example : In the ionic compounds, like sodium chloride are soluble in the water. And as we know that the water molecules are polar in nature. So, they interact with the sodium and chloride ions.

Hence, the polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes.

A CaCl2 solution is given to increase blood levels of calcium. If a patient receives 6.1 mL of a 12 % (m/v) CaCl2 solution, how

Yuliya22 [10]

Mass of CaCl₂ = 0.732 g

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

$\tt \%(m/v)\rightarrow 12\%=\dfrac{mass~CaCl_2}{volume~of~solution}\times 100\%\\\\mass~CaCl_2=12\%\times 6.1\div 100\%\\\\mass~CaCl_2=0.732~g$

An antacid tablet with an active ingredient of CaCO3 was dissolved in 50.0 mL of 0.300 M HCl. When this solution was titrated wi

yaroslaw [1]

Answer:

Explanation:

mole of HCl remaining after reaction with CaCO₃

= .3 M of NaOH of 32.47 mL

= .3 x .03247 moles

= .009741 moles

Initial HCl taken = .3 x .005 moles = .0015 moles

Moles of HCl reacted with CaCO₃

= .009741 - .0015 = .008241 moles

CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O .

1 mole 2 moles

2 moles of HCl reacts with 1 mole of CaCO₃

.008241 moles of HCl reacts with .5 x .008241 moles of CaCO₃

CaCO₃ reacted with HCl = .5 x .008241 = .00412 moles

the mass (in grams) of calcium carbonate in the tablet

= .00412 x 100 = .412 grams . ( molar mass of calcium carbonate = 100 )

In the process of eating, what kind of energy in food is transformed into heat energy by your body?

Rama09 [41]

Answer:The chemical energy

Explanation:because The chemical energy in the food you eat is changed into another kind of chemical energy that your body can use. Your body then uses that energy to give you the kinetic energy that you use in everything you do.
