Answer: 0.45 mole Fe
Explanation: solution
25 g Fe x 1 mole Fe / 56 g Fe
= 0.45 mole Fe
Cancel out grams of Fe.
Answer:
Explanation:
Convert the word equation to a chemical equation.
one atom magnesium + two atoms Cl form magnesium chloride
Mg + 2Cl ⟶ MgCl₂
Answer is: Keq = [CO₂].
Balanced chemical reaction: CaCO3(s) ⇄ CaO(s) + CO₂(g).
The equilibrium constant (Keq) is a ratio of the concentration of the products to the concentration of the reactants.
Pure liquids (shown in chemical reactions by appending (l) to the chemical formula) and solids (shown in chemical equations by appending (s) to the chemical formula) not go in to he equilibrium constant expression, only gas state (shown in chemical reactions by appending (g) to the chemical formula) reactants and products go in to the equilibrium constant expression.
Answer:
the correct option is c
Explanation:
Biological chemical reactions that provide energy are considered spontaneous, therefore the deltaG value would be negative.
B. elements
It's called the periodic table (of the elements)
