Answer:
Explanation:
525ml of 0.6550M MgCl₂ => 0.525L x 0.650M = 0.3413mole MgCl₂
0.3413mole MgCl₂ = 0.3413mole x 94 g/mole = 32.1g MgCl₂
Answer:
4
Explanation:
Since there are 3 carbons on the left side, make the coefficient of CO2 equal to 3.
Also, since there are 8 hydrogen on the left side, make the coefficient of H2O equal to 4.
This means there are 3(2)+4=10 oxygen atoms on the right, making the coefficient of O2 equal to 5.
Let us assume that this molecule is 100 percent ionic. In that case, the charges are distinguished by a bond length.
h = Q × r
= (160 × 10⁻¹⁹ c) (127 × 10⁻¹² m) (10 / 3.336 × 10⁻³⁰ cm)
= 6.09 D.
The actual dipole moment is = 1.08 D
Therefore, the percent ionic character is,
= 1.08 D / 6.09 D × 100
= 17.7 %.
Rough, tan, grainy, and scratchy are some
Answer:2
Explanation:because the compound is CaI2, Ca needs to lose 2 electrons and I needs to gain 1 electron to reach an octet and so there will be 2 I atoms therefore 2 electron transfer
