Answer:
5
Explanation:
(2n+1 C + N - H - O)÷2=(9×2+2-10)÷2=5
<span>It makes no difference which reactant is placed first, a strong acid combined stoichiometrically with a strong base will produce a neutral solution. Due to hydrolysis, a weak acid and strong base produce a basic solution when combined stoichiometrically, and a weak base and strong acid produce an acidic solution when combined stoichiometrically
Mark as brainlist please if correct! BTW have a blessed day!</span>
Answer:
C is the only one that is true
The Kelvin temperature K =℃ + 273.15. ℃ means centigrade temperature. So the centigrade temperature number between freezing point and boiling point is equal to the number of Kelvin. So the answer is 357-(-38)=395.
<span>There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. Therefore, the molarity of the given solute in the solution is:
Molarity = 5 moles / 2 L = 2.5 moles / L</span>
