What does the number 8563 mean?
Its mean the number 8563 !
What does a negative number in brackets mean?
It means that you treat it as a negetive number instead of as "minus one".For example:3-1=2But:3(-2)=-6.
What is the mean of 7 8 8 2 10 8 7?
Take the sum of the numbers divided by the number of numbers. Mean = (7+8+8+2+10+8+7)/7 = 7.14

What is the chemical formula of magnesium and chloride?
Magnesium chloride has MgCl2 as its chemical formula. This ionic salt loves water, and will "suck it out of the air" to form MgCl2(H2O)x as it absorbs moisture. More can be found on this substance in the Wikipedia post, and a link is provided.

What does MgCl2 mean in the periodic table?
Magnesium Chloride
How many atoms are on one mole of MgCI?
To determine the number of atoms in one mole of MgCl2 (magnesium chloride), you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms/molecules per mole. First, you need to calculate the molar mass of MgCl2. Magnesium (Mg) has an atomic mass of approximately 24.31 g/mol. Chlorine (Cl) has an atomic mass of approximately 35.45 g/mol (rounded to two decimal places). Now, add the atomic masses of one magnesium atom and two chlorine atoms to find the molar mass of MgCl2: MgCl2 molar mass = (1 x Mg atomic mass) + (2 x Cl atomic mass) MgCl2 molar mass = (1 x 24.31 g/mol) + (2 x 35.45 g/mol) MgCl2 molar mass = 24.31 g/mol + 70.90 g/mol MgCl2 molar mass = 95.21 g/mol So, the molar mass of MgCl2 is approximately 95.21 g/mol. Now, using Avogadro's number, you can calculate the number of atoms in one mole of MgCl2: Number of atoms in 1 mole of MgCl2 = 6.022 x 10^23 atoms/molecules per mole Now, divide this by the molar mass of MgCl2 (95.21 g/mol): Number of atoms in 1 mole of MgCl2 = (6.022 x 10^23 atoms/mol) / (95.21 g/mol) Number of atoms in 1 mole of MgCl2 ≈ 6.32 x 10^21 atoms So, there are approximately 6.32 x 10^21 atoms in one mole of MgCl2.
What is the formula of a compound formed when mg plus 2 and cl- react?
MgCl2 is formed. Mg2+ + 2Cl- ----> MgCl2
If you have 45 grams of MgCl2 and dissolved it in 0.5 L. Find the molarity of MgCl2?
45 g MgCl2 x 1 mole MgCl2/95.2 g /0.5 L = 0.9045 moles/L = 0.90 M (to 2 significant figures)
