The state of butter has changed. it only melted, and no new substance is formed or mixed with another substance
Answer:
True
Explanation:
Sometimes you will need to convert from grams to moles, or moles to grams
That would be 1 becuase A is N while B has its own value, so if B is 2 and That equals C A would be 1
Answer is: 0,0095 mol of hydrogen gas will be produced in reaction.
Chemical reaction: Ca + 2HCl → CaCl₂ + H₂.
m(Ca) = 0,38 g.
n(H₂) = ?
n(Ca) = m(Ca) ÷ M(Ca).
n(Ca) = 0,38 g ÷ 40 g/mol
n(Ca) = 0,0095 mol.
from reaction: n(Ca) : n(H₂) = 1 : 1.
n(H₂) = n(Ca) = 0,0095 mol.
n - amount of substance.
Explanation:
A reversible reaction is a reaction which results in the formation of products which gives back reactants. Therefore, it is said that a reversible reaction occurs in both forward and backward direction.
Thus, it can be concluded that a reversible reaction is a reaction that takes place in the both directions . If the reaction were to equilibrium, the rate of the forward reaction would equal that of the reverse reaction.equilibrium.
