Heat the solvent/solution with the solute over a Bunsen burner whilst mixing it with a glass storing rod or break up the solid into a powder to increase its surface area and then mix it with the solvent/solution.
Answer:
option b= 1.26 mol/L
Explanation:
Given data:
moles = 2.34 mol
volume = 1860 mL
Solution:
molarity = moles of solute/ volume in L
First of all we will convert the mL in L,
1860 mL / 1000 = 1.86 L
now we will put the values in formula,
molarity = 2.34 mol / 1.86 L
molarity = 1.26 mol/L
Answer:
negative
Explanation:
Exothermic reaction - energy is out of system, so energy of system becomes smaller, and ΔH<0.
One type of chemical process that can be either exothermic or endothermic is dissolving of salts in water. A salt is a compound made up of positively charged ions and negatively charged ions which are held together in a solid state because the positive and negative charges attract one another.
I think it’s C.Vinegar but not sure hope this helps
