Answer:
<u>2</u> NaBr + <u>1</u> Ca(OH)2 ---> <u>1</u> CaBr2 + <u>2</u> NaOH
Explanation:
question 44
the number 35 of bromine represents the atomic number
question 45
29 protons,
27 electrons
29-27 = +2
the charge on the following particle is
+2
[OH⁻]=2*0.00043m=0.00086 m=8.6*10⁻⁴
[OH⁻]*[H⁺]=10⁻¹⁴
8.6*10⁻⁴*[H⁺]=10⁻¹⁴
[H⁺]=10⁻¹⁴/8.6*10⁻⁴=1.2*10⁻¹¹
