Answer:
HCl is a polar covalent compound, because of electronegativity difference between Cl(3.5) and hydrogen (2). Hence in this way, the bond between HCl breaks and they formed ions in the polar solvent like water .
Answer:
Heyy Mason, I donʻt know if you got the answer already but I was also trying to find the answer haha and came across this. Might as well help you since I eventually stopped being lazy and did the calculations...The answer is 144 L.
Explanation:
Use Charles Law to solve this
V1 = 50.0L
T1 = 205K
V2 = ?
T2 = 590K
using V1/T1 = V2/T2 plug in the numbers
50.0L/205K = V2/590K
Switch it around so V2 is isolated
V2 = 590K(50.0L/205K)
cancel out the K
solve
you get 143.90243
round to 144
Answer:
13.2% Mg, 86.8% Br
Explanation:
Mg has a molar mass of 24.31g/mol.
Bromine has a molar mass of 79.90 g/mol.
There is one mole of Mg and two moles of Br in the compound:
79.90x2 + 24.31 = 184.11
So the total molar mass of MgBr2 is 184.11.
A percent tells us a part of a whole, so we will divide each part of the mass into the whole mass.
24.31g Mg / 184.11g MgBr2 = .132
159.8g Br / 184.11g MgBr2 = .868
Multiply these decimals by 100 to make them into a percent.
.132 x 100 = 13.2% Mg
.868 x 100 = 86.8% Br
Answer:
4.716x10^25
Explanation:
1 molecule of water is equivalent to 6.02x10^23
hence 78.34 is equivalent to 78.34x6.02x10^23
and the answer is 4.716x10^25
