Explanation:
From the equation each mole calcium bromide makes 2 moles sodium bromide
1) 5 x 2 = 10 moles sodium bromide
2) 2 moles of calcium bromide will make 2 moles of calcium sulfate ( from the equation)
mole weight of calcium sulfate =
Ca = 40 S = 32 O4 = 64 total mole weight = 136 gm
two moles would weigh 272 gms
3) 845 gm of calcium sulfate is 845 gm / 136 gm/mole = 6.21 moles
6.21 moles of Ca Br2 will be needed
6 .21 ( 40 + 2 *79.9) = 1240.76 gm

The balanced equation shows how sodium chloride reacts with silver nitrate to form sodium nitrate and silver chloride. nacl agno3 right arrow. nano3 agcl if 4.00 g of nacl react with 10.00 g of agno3, what is the excess reactant? agcl nacl agno3 nano3
Answer:
The excess reactant is the NaCl.
Explanation:
NaCl(aq) + AgNO3 (aq) → NaNO₃(aq) + AgCl (s) ↓
This is a precipitation reaction.
We need to convert the mass of each reactant to moles:
4 g / 58.45 g/mol = 0.068 moles of NaCl
10 g / 169.87 g/mol = 0.059 moles of nitrate.
As stoichiometry is 1 by 1, 1 mol of chloride will react with 1 mol of nitrate.
If I have 0.059 moles of nitrate, I will need the same amount of chloride and I have 0.068 moles. I still have chloride, therefore the excess reactant is the NaCl.
0.068 mol - 0.059 mol = 0.009 moles are the moles of NaCl that remains after the reaction is complete
Answer:
NaCl

How many moles of Ca(NO) are there in a sample with a mass of 50.0 g?
a. 0.305 mol
b. 0.333 mol
c.
0.490 mol
d. 8200 mol
Answer:
0.305 mol
Explanation:
Ca(NO) is not a molecule. I think you meant to type Ca(NO3)2, which is calcium nitrate.
The moles of a compound is equal to is mass divided by its molar mass.
The molar mass of Ca(NO3)2 is 164.09 g/mol.
50.0 / 164.09 = 0.305

If a reactant is in excess, why do we not worry about the mole ratios involving that reactant?.
Answer: The limiting reactant will be used up first, meaning the reaction can no longer occur with only the excess reactant.
Explanation:
In a reaction the reactant which determines the yield of the reaction is called limiting reactant. Whereas, the reactant which is excess in amount does not itself lead the reaction after the limiting reactant is consumed.
What is excess reactant?In a reaction, the yield of the product depends on the number of moles of reactants. The reactants which is not sufficient in amount is determining the yield because as soon as this reactant is consumed, the production stopes.
The excess reactant on the other hand is excess in amount which can't lead the reaction alone after the consumption of the limiting reactant. Hence, we don't have to worry on the excess reactant.
The limiting reactant of a reaction can be determined by calculating the number of moles of each reactants participating in it.

The elements of a group have the same number of ___________________ in their ______________ shell
Answer:
Same amoung of electrons in their outer shell
Explanation:
elements in the same group have the same number of electrons in their outer shell this is why they are in the same group
The elements of a group have the same number of valence electrons in their outermost shell.
Why do the elements of the same group have similar chemical behavior?The chemical properties of elements are described by the number of valence electrons in their outermost shell. The chemical elements placed in the same group have the same number of valence electrons in their valence shell. Therefore, the chemical elements placed in the same group of the periodic table have similar chemical behavior.
The elements having identical valence electronic configurations in their atoms are arranged in the same group of the modern periodic table. These valence electrons are accountable for the chemical properties and reactivities of the elements.
For example, the chemical properties of all elements in group 1 are similar as they have only one electron in their valence shell. The chemical elements of group 17 have seven electrons in their valence shell they are halogens with similar chemical behavior.
