(A) Naoh + Hno3 == Nano3 + h20.
and it is acid based reaction.
(B) H + Br == Hbr. it is synthesis reaction
and it should be hydrogen gas with bromine gas if that was question then
H2 + Br2 == 2Hbr
(c) 3Agno3 + Alcl3 == Al (No3)3 + 3Agcl
it is double displacement. and we right the polyatomic ion in bracket that’s why no3 is in bracket.
please let me know if you need something

a. Sodium hydroxide reacts with nitric acid

Naoh + Hno3 == Nano3 + h20.

acid based reaction.

b. Hydrogen + bromine

H + Br == Hbr

H2 + Br2 == 2Hbr synthesis reaction

c. Silver nitrate + aluminum chloride

3Agno3 + Alcl3 == Al (No3)3 + 3Agcl double displacement.

<span>In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide. Balanced chemical equation for this reaction is given below. Na-sodium , H2o- water, H-hydrogen gas and NaOH- aqueous sodium hydroxide. Two atoms of Na react with two atoms of water and this reaction will give us H (hydrogen gas) and two atoms of NaOH (aqueous sodium hydroxide). 2Na + 2 H2o = H2 +2NaOH.</span>

During early research in nuclear energy, why were scientists surprised that the products from splitting a uranium nucleus had le
creativ13 [48]
Scientists expected that the law of conservation of mass would apply to nuclear fission in terms of the masses of the subatomic particles. In reality, the mass of an atom is not equal to the sum of the masses of the subatomic particles that make it up. This is because of the energy that binds the subatomic particles. This energy has mass and when the bond is broken, the mass of the energy of the bonds is lost resulting to what we now cal, a mass defect.
