we know that,
W = mL + mcθ
W= 10(336+ 4.2(50))= 5460 kJ
so quantity of heat required is 5460 J

<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:
b. reduces pain and fever
The strength of an acid relates to the number of free ions in solution while the concentration of an acid relates to the number of ions that it contributes to a solution.
Answer:
No of moles of carbon = 9.63 mol
Explanation:
No of atoms of carbon = 5.8 × 10²⁴
Avogadro's no. = 6.022 × 10²³
No. of moles = No. of atoms / Avogadro's no.
N = 5.8 × 10²⁴ / 6.022 × 10²³
N = 9.63 mol
∴ No of moles of carbon = 9.63 mol
