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:
A. Reactants
Explanation:
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
Answer:
2 L
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above, we can see clearly that 1 L of O₂ reacted to 2 L of H₂O.
This implies that 2 L of H₂O can be obtained by the reaction of 1 L of O₂.
Thus, option 3 gives the correct answer to the question.
Answer: s (solid), l (liquid), g (gas), aq (Aqueous)
