335K would be expressed as 61.85 degrees Celsius
First there is a need to calculate the molar mass of Ba(NO₃)₂:
137.3 + 2 (14.0) + 6 (16) = 261.3 grams/mole
The molar mass, denoted by M in chemistry refers to a physical characteristic illustrated as the mass of a given component divided by the amount of the component. The molar masses are always denoted in grams/mole.
After finding the molar mass, the number of moles can be identified as:
432 grams / 261.3 g/mol = 1.65 moles of Ba(NO₃)₂.
Answer:
magnesium (Mg)
Explanation:
Both are in group 2 and because of that share the same chemical properties.
<u>Answer</u>:
Charlie adjust the coefficients to make the number of atoms in the reactants the same as the number of atoms in the
<u>Explanation</u>:
Stoichiometric coefficients are the number that appears before the symbol in each compound or element in the equation of a chemical reaction. By rule, it is positive for products and negative for reactants. Stoichiometric coefficients help in describing the stoichiometry of a chemical reaction.
According to "law of conservation of mass" that states "total reactant's mass equals the overall mass of obatined from the product". Thus, Charlie would adjust coefficients to equalise the number of atom in reactants and products.
