If an element is found in group 2 on the periodic table, you can infer that it has two valence electrons, it has a high reactivity (alkaline earth metals), and the oxidation number is 2+
Answer:
Hence, option B is correct. 1 and 2
Explanation:
NH 4 Cl is a weak base-strong acid salt.
NaCN is a salt of a strong base (NaOH) and weak acid (HCN).In water,
1. NH 4 Cl produces acidic solution
2. KHSO 4 produces acidic solution
because the neutral salt of strong base KOH and strong acid H 2 SO 4 is K 2 SO 4
3. NaCN produces basic solution
4. KNO
3 produces neutral solution
I think this is right but I hope its help ,ur welcome ♥️♥️
Answer:
9.52 kg/mL
Explanation:
Density = mass/ Volume
= 100 kg/ 10.5 mL
= 9.523809524 kg/mL
OR
100 kg = 100 × 10^3 g
》Density = 100 × 10^3 g/ 10.5 mL
= 9523.809524 g/mL
