Answer
4.0/5
4
Explanation:
The balanced chemical equation will be;
H2SO4 + 2NaOH → Na2SO4 + 2H2O
The equation for the reaction is balanced by using coefficients; 1,2,1,2
According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.
For the law of conservation of mass to be obeyed, chemical equations must always be balanced.
Answer:
The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants.
