6,022 x 1023 atoms/mole. Calcium nitrate = Ca(NO3)2 .
There are 1 mole of calcium making 6,022 x 1023 atoms of calcium.
There are 2 moles of nitrate-ions and each nitrate-ion is made up of 1 mole nitrogen, and 3 moles of oxygen. Thath means that the nitrate ion in calcium nitrate has 6 moles oxygen and 2 moles of nitrate:
Atoms of nitrogen: 6,022 x 1023 moles-1 x 2 moles = 1,2044 x 1024 atoms
Atoms of oxygen: 6,022 x 1023 moles-1 x 6 moles = 3,6132 x 1024 atoms
there are three oxygen atoms in calcium nitrate
9 atoms :) Your soo welcome, i had to ask around my school to find the answer. :) im also in 8th grade.
Calcium nitrate contain two nitrogen atoms in the formula unit.
6022 x1024
Ca (NO3)2 So the number of Ca atoms will just be Avogadro's constant, L
Magnesium nitrate is MgNO3 and there are one magnesium atom one nitrogen atom three oxygen atoms no potassium atoms
Calcium sulfide (CaS) has two atoms.
francium ceasium Potassium Sodium Lithium These metals could react with calcium nitrate in a displacement reaction as they are more reactive. e.g. pottasium + calcium nitrate -> calcium + pottasium nitrate.
61,5 g calcium contain 9,241.10e23 atoms.
Calcium nitrate has 9 atoms.
Calcium nitrate has 9 atoms.
Calcium ions have a charge of +2 and nitrate ions (NO3) have a charge of -1. Because compounds are neutral, you need two nitrate ions to cancel out one calcium ion. Thus the formula for calcium nitrate is Ca(NO3)2. Nitrate has four atoms (one nitrogen and three oxygen). But there are two nitrate ions, so that makes eight atoms. Then you add on the one calcium atom for a total of nineatoms.
Ca (NO3)2 So the number of Ca atoms will just be Avogadro's constant, L
This compound is calcium nitrate. Each formula unit will contain 9 atoms.
This compound is calcium nitrate. Each formula unit will contain 9 atoms.
Calcium Nitrtae is Ca(NO3)2 and so there are two moles of nitrate per mole of calcium nitrate. Thus there are 2 x 2.50 = 5.0 moles of nitrate present.
there are 20 atoms in calcium
The calcium ion is Ca2+ and the nitrate ion is NO3- and together they form Ca(NO3)2
Magnesium nitrate is MgNO3 and there are one magnesium atom one nitrogen atom three oxygen atoms no potassium atoms
No. Calcium nitrate is an ionically bonded salt.
Calcium sulfide (CaS) has two atoms.
