Answer:

Ni^2+ is most likely

Ti^3+ is very unlikely

Explanation:

The Crystal Field Stabilization Energy almost always favors octahedral over tetrahedral in very many cases, but the degree of this favorability varies with the electronic configuration. In other words, for d1 there is only a small gap between the octahedral and tetrahedral lines, whereas at d3 and d8 is a very big gap. However, for d0, d5 high spin and d10, there is no crystal field stabilization energy difference between octahedral and tetrahedral. The ordering of favorability of octahedral over tetrahedral is:

d3, d8 > d4, d9> d2, d7 > d1, d6 > d0, d5, d10. This explains the answer choices above.

Ti^3+ being a d1 specie is least likely to exist in octahedral shape while Ni2+ a d8 specie is more likely to exist in octahedral shape.

Consider the balanced chemical equation that follows. You are asked to determine how many moles of water you can form from 4 mol

kodGreya [7K]

<u>Answer:</u> The correct answer is $4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O$

<u>Explanation:</u>

We are given:

Moles of hydrogen gas = 4 moles

As, oxygen is given in excess. Thus, is considered as an excess reagent and hydrogen is considered as a limiting reagent because it limits the formation of products.

For the given chemical equation:

$2H_2(g)+O_2(g)\rightarrow 2H_2O(l)$

By Stoichiometry of the reaction:

2 moles of hydrogen produces 2 moles of water molecule.

So, 4 moles of hydrogen will produce = $\frac{2molH_2O}{2molH_2}\times 4molH_2=4mol$ of water.

Hence, the correct answer is $4molH_2\times \frac{2molH_2O}{2molH_2}=4 molH_2O$

How many joules are required to heat 2 l of water in a pot from 20 ◦c to the boiling point of water? the specific heat of water

miss Akunina [59]

The joules required to heat 2L of water in a pot from 20 c to the boiling point of water is calculated using the following formula

Q= MC delta T
M = mass = density x volume( 2 x 1000= 2000ml)
M = 1g/ml x2000 ml = 2000g
C = specific heat capacity = 4.18 g/c
delta T = change in temperature = 100 c ( boiling point of water) - 20 c = 80 c
Q is therefore = 2000 g x 4.18 j/g c x 80c = 668800j
