The reaction of calcium and zinc carbonate yields calcium carbonate and zinc. To balance, we should remember that the number of atoms of each element in the reactants and products side should be equal. The balanced chemical reaction is written as follows:

Ca + ZnCO3 = CaCO3 + Zn

Answer : The balanced chemical reaction will be,

Ca+ZnCO_3\rightarrow CaCO_3+Zn

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

As per question, when calcium react with zinc carbonate then it react to give calcium carbonate and zinc as a product.

The balanced chemical reaction will be,

Ca+ZnCO_3\rightarrow CaCO_3+Zn

This reaction is a single replacement reaction in which the most reactive elements displaces the least reactive element from its solution.

Why is copper (i) sulfate Cu2So4^-2? not copper (ii)?
const2013 [10]
Copper (I) oxidation state is 1 Cu2So4
copper (II) oxidation state is +2 CuSo4
copper (i) also give up one electron so you need two of them to react with the sulfate ion (which has charge of -2)
and also all metallic ions have an multiple oxidation levels corresponding to the number of electrons they can exchange or loose

A speed time graph shows that a car moves at 20 m/s for 15s. The car's speed steadily decreases until it comes to a stop at 40s.
ladessa [460]
0s to 15s: constant speed/zero acceleration
15s to 40s: constant gradient, therefore constant deceleration

Answer: In Galileo’s time, what was considered the “center of everything”? The Earth! All of the planets and even the Sun went around “us”. Of course, when Galileo saw the moons of Jupiter passing in front of the planet, and disappearing to show up again, it was clear to him that these moons went around Jupiter like our moon goes ‘round the Earth.

That did not set well with the Beliefs of the day, and that is at least one answer!
