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
Answer:
The correct answers are given below
Explanation:
1 An increase of one in atomic number and no change in the mass number.
2 All the above statements are correct.
3 A decrease of one in atomic number and a decrease of four in mass number.
4 Have a high neutron to proton ratio.
When a liquid is frozen, the atoms in the liquid slow their movement due to lack of energy so the substance becomes hard.
A short circuit is an easier path for electron flow
