Answer:
Zinc oxide is react with sulphuric acid to give zinc sulphate and water.
zinc oxide +sulphuric acid ⇒ zinc sulphate + water
Zno +H2So4 ⇒ZnSo4 + H2O
SULPHURIC ACID = H2SO4
ZINC SULPHATE =ZnO
Explanation:
The correct option is B. The alkali metals combine directly with halogens forming high melting point crystalline solids that have high negative enthalpies of formation. The entalphy of formation for lithium bromide is the highest and the values decrease down the group, thus, lithium is the most stable while cesium is the least stable.
They occur at the same temperature.
The electron affinity increases from left to right
Then <u>THE CAR WILL NOT MOVE!!</u>
