What is the maximum mass of s8 that can be produced by combining 89.0 g of each reactant?
lidiya [134]

Answer : We can produce 125.7 g of S_{8}.


Explanation : The reaction will be

8SO_{2} + 16H_{2}S -----> 3S_{8} + 16H_{2}O


The molecular mass of SO_{2} is 64.1 g/mol

and molecular mass of H_{2}S is 34.1 g/mol


For every mole of SO_{2} we would need twice of H_{2}S moles, so for every 3 moles of S_{8} we need 16 moles of H_{2}S


Now, we can calculate number of moles S_{8}

2.61 X (3/16) = 0.49 moles


Here, the molecular mass of S_{8} is 256.8 g


multiplying it with the number of 0.49 moles we get, 256.8 X 0.49 = 125.7 g of S_{8}.


Hence, 125.7 g of S_{8} will be produced.

Lonization Energy decreases as you go down a family (group or column). Explain why this pattern
Goryan [66]

Answer:

Explanation:

As you move down a group, first ionization energy decreases. WHY? Electrons are further from the nucleus and thus easier to remove the outermost one.

2. What was the primary reason in the 1850's driving the curiosity of atoms?
nalin [4]

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.
