It is an endothermic reaction because the products hAve more heat than the reactions so it was a gain of heat which makes the enthalpy Change positive !

Considering the definition of mass volume percentage, the percent concentration of dextrose is 45%.
<h3>Mass volume percentage</h3>
Mass volume percentage (% m/V) is a measure of concentration that indicates the number of grams of solute per 100 volume units of the solution. In other words, the volume percent of a component in the solution is defined as the ratio of the mass of the component to the volume of the solution, expressed as a percentage.
The mass volume percentage of a solution is determined by the following expression:

<h3>Percent concentration in this case</h3>
In this case, you know:
- mass of solute= 450 grams
- volume of solution= 1 L= 1000 mL
Replacing in the definition of mass volume percentage:

Solving:
<u><em>mass volume percentage= 45%</em></u>
Finally, the percent concentration of dextrose is 45%.

Answer:
Lipids.
Explanation:
Steroids are known as the type of lipid which consists of 4 rings of carbon atoms. All steroids have 1 five-sided carbon ring and a 3 six-sided carbon ring. They are works as a hormone in the body and secreted by the ovaries and testes.
Steroids differ in functional groups. When this functional group attached to the steroid ring it gives steroids with a different function. They are composed of largely carbon, and hydrogen atoms. They are insoluble in nature in water.
