There are ________ mol of bromide ions in 0.700 L of a 0.400 M solution of AlBr

Chemistry
1 answer:
denis23 [38]2 years ago
5 0

Answer:

The number of moles of AlBr3 = Molarity × Volume

= 0.400 × 0.700

= 0.28 moles

1 mole of AlBr3 gives 3 moles of Br- ions

That is

AlBr3 = Al3+ + 3Br-

Therefore, 0.045 moles of AlBr3 will yield 3 × 0.28 = 0.84 moles

Thus; they are 0.84 moles of bromide ions

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()bao
just olya [345]

Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.

Given chemical reaction is:

BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄

Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.

Hence the required coefficients is 1.

Molecules can be either positively or negatively charged depending upon their elemental arrangement
Nuetrik [128]
They are positively or negatively charged based on their electrical configuration of electrons*
For example an electronic configuration of 2,8,3 would have a negative charge if +3 since it needs to lose 3 electrons to gain the electrical configuration of a noble gas
2,8,1 would have a charge of +1 for the same reason
2,8,6 would be -2 since it is easier to gain 2 electrons that lose 6 electrons

Hope this helped :))
