Answer:
2
Explanation:
Mass of water molecule = mass of hydrated salt - mass of anhydrous salt
Mass of water molecule = 5.00 - 4.26 = 0.74g of water molecule.
Number of moles = mass / molarmass
Molar mass of water = 18.015g/mol
No. of moles of water = 0.74 / 18.015 = 0.0411 moles.
Mass of BaCl2 present =?
1 mole of BaCl2 = 208.23 g
X mole of BaCl2 = 4.26 g
X = (4.26 * 1) / 208.23
X = 0.020
0.020 moles is present in 4.26g of BaCl2
Mole ratio between water and BaCl2 =
0.0411 / 0.020 = 2
Therefore 2 molecules of water is present the hydrated salt.
I’m not completely sure what you mean here but if your talking about charges in covalently bonded molecules then here is something:
Charges in covalent bonds are partial because the ions are shared when bonding.
The charges are no longer full and strong they are half charges, they are not as strong.
You might want to just google a little bit. :)
Hope that helps
Maybe because meiosis have more chromosomes than mitosis but don't put that on there but that maybe it it because in class we have not went over that yet
