Explanation:
A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. Many double displacement reactions occur between ionic compounds that are dissolved in water. A double replacement reaction is represented by the general equation.
1.23x10^2
So there should be one number to the left at all times, even a zero when it comes to decimals and negative scientific numbers. Also 10 is raised to the power by how many you need to move the decimal for the original number.
Answer: 11.0 g of calcium will react with 10.0 grams of water.
Explanation:
To calculate the moles, we use the equation:
moles of
The balanced chemical equation is:
According to stoichiometry :
2 moles of
require = 1 mole of
Thus 0.55 moles of
require=
of
Mass of
Thus 11.0 g of calcium will react with 10.0 grams of water.
Answer:
2 moles
Explanation:
From periodic table , mole weight of CH4 = 16 gm/mole
32 gm / 16 gm/mole = 2 moles
