due to there reactive rate?
Answer:
Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction. The mass ratios can be calculated by dividing each by the total in the whole reaction.
Explanation: Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products.
Answer:
the reaction is: Na2CO3 + 2HCl ===》 2NaCl + H2O + CO2(g)
Answer:
0.098 moles
Explanation:
Let y represent the number of moles present
1 mole of Ba(OH)₂ contains 2 moles of OH- ions.
Hence, 0.049 moles of Ba(OH)2 contains y moles of OH- ions.
To get the y moles, we then do cross multiplication
1 mole * y mole = 2 moles * 0.049 mole
y mole = 2 * 0.049 / 1
y mole = 0.098 moles of OH- ions.
1 mole of OH- can neutralize 1 mole of H+
Therefore, 0.098 moles of HNO₃ are present.
We know that density is a measure of mass per unit of volume:
Density = Mass / Volume
Therefore, we can calculate for the mass
Mass = Density * Volume
if the density of water is 1 g/cm^3:
Mass = Density * Volume
= (1 g/cm^3) * 94.60 cm^3
= 94.60 g
is named as hydroxide,
is named as sulfate and so on..
