This kind of frog is an anaxyrus fowleri
Answer:
A. copper is highly water soluble. It will turn into 5 different hydrates as it absorbs more and more water.
b. Glycerol is easily soluble in water, due to the ability of the polyol groups to form hydrogen bonds with water molecules
c. octane is considered to be non-polar, it will not be soluble in water, since water is a polar solvent. This will happen because octane (hydrocarbons in general) contains neither ionic groups, nor polar functional groups that can interact with water molecules.
d. Nitric acid decomposes into water, nitrogen dioxide, and oxygen, forming a brownish yellow solution.
e. Barium carbonate is a white powder. It is insoluble in water and soluble in most acids
Explanation:
I'm pretty sure it's A, but then again I'm only in 8th grade. Sorry if this doesn't help:(
Given the mass percentage of HCl solution = 15.00 %
This means that 15.00 g HCl is present in 100 g solution
Moles of HCl = 
Density of the solution = 1.075 g/mL
Calculating the volume of solution from density and mass:

Converting volume from mL to L:

Calculating the molarity of HCl solution from moles and volume:

<h3><u>Answer;</u></h3>
A. the reactants and the products.
<h3><u>Explanation</u>;</h3>
- The enthalpy of a reaction is the heat released or absorbed by a reaction at constant pressure.
- Enthalpy is important as it tells us the amount of heat energy present in a system. In chemical reactions it tells us the amount of heat energy lost or gained.
- <em><u>Changes in enthalpy are determined as the reactants are converted into products. Therefore, enthalpy depends on the reactants and the products. In other words it depends on the heat of reactants and that of products.</u></em>
