In the laboratory, a quantity of I2 was reacted with excess H2 to give 1.26 moles of HI. It is also known that the percent yield
Anon25 [30]

Answer:

1.008moles of iodine

Explanation:

Hello,

This question requires us to calculate the theoretical yield of I₂ or number of moles that reacted.

Percent yield = (actual yield / estimated yield) × 100

Actual yield = 1.2moles

Estimated yield = ?

Percentage yield = 84%

84 / 100 = 1.2 / x

Cross multiply and solve for x

100x = 84 × 1.2

100x = 100.8

x = 100.8/100

x = 1.008moles

1.008 moles of I₂ reacted in excess of H₂ to give 1.2 moles of HI

How can a Hydrogen atom turn into a<br> Hydrogen ion (H+)?
Butoxors [25]

Answer:

By losing an electron

Explanation:

Electrons have a negative charge. So, losing one would give an element a more positive charge. You can usually find a hydrogen ion (H+) in substances like acids.

If the formula for a compound is represented by X3Y2 and the charge on the Y ion is -3, what is the charge in the X ion?
artcher [175]
I cannot fully remember but the charge of a compound always has to be the same.  However, I believe that the sign of the Y2 means that it is positive 2. 

so in my opinion it is in between b and c. use your best judgment.
