C. Trigonal planar
D. Linear
Answers
Answer:
A
Explanation:
Tetrahedral
The term that describes the molecular structure is Tetrahedral. The correct option is A.
What is molecular structure?The molecular structure is the structure of the molecular compounds. It tells the presence of ions and bonds in a compound. It is the arrangement of atoms, groups, or ions in a molecule, as well as the quantity and distribution of chemical bonds.
The use and importance of molecular structure are comprehending Nature's complex design principles and blueprints depend on understanding molecular structure.
Perhaps we can start to imitate her lovely items more cheaply and with less negative environmental effects if we can comprehend her plans and fundamental materials. The given compound is tetrahedral.
Thus, the correct option is A. Tetrahedral.

M(s) + 2 X2(g) → MX4(g) −98.7 kJ/mol
X2(g) → 2 X(g) +327.3 kJ/mol
M(g) → M(s) −20.1 kJ/mol
calculate the average bond energy for a single
M-X bond.
Answer in units of kJ/mol.
Answers
Answer:
Explanation:
M(s) → M (g ) + 20.1 kJ --- ( 1 )
X₂ ( g ) → 2X (g ) + 327.3 kJ ---- ( 2 )
M( s) + 2 X₂(g) → M X₄ (g ) - 98.7 kJ ----- ( 3 )
( 3 ) - 2 x ( 2 ) - ( 1 )
M( s) + 2 X₂(g) - 2 X₂ ( g ) - M(s) → M X₄ (g ) - 98.7 kJ - 2 [ 2X (g ) + 327.3 kJ ] - M (g ) - 20.1 kJ
0 = M X₄ (g ) - 4 X (g ) - M (g ) - 773.4 kJ
4 X (g ) + M (g ) = M X₄ (g ) - 773.4kJ
heat of formation of M X₄ (g ) is - 773.4 kJ
Bond energy of one M - X bond = 773.4 / 4 = 193.4 kJ / mole

calculate the oxidation number of s in S2O8^2-
Answers
Given problem:
S₂O₈²⁻
Find the oxidation number of S;
Oxidation number presents the extent of oxidation of each atom of elements a molecular formular or formula unit or an ionic radical.
For radicals:
"the algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to the charge on the ion "
S₂O₈²⁻; oxidation number of O is usually -2
2(S) + 8(-2) = -2
2S - 16 = -2
2S = -2 + 16
2S = 14
S = +7
The oxidation state of S in the radical is +7
Explain what happens if you change the number of protons in an element?
Plzzz helpppp!!!
Answers
Answer:
When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive. If you change the number of electrons in an atom, you will get an ion of the element.

A chemist burns 0.8 g of iron in oxygen.
The iron reacts to form 1.1 g of iron oxide.
Calculate the mass of oxygen that reacted with the iron.
Answers
Answer:
0.3g
Explanation:
1.1 - 0.8 = 0.3
Hope this helps
The mass of oxygen that reacted with the iron is 0.3g
The chemist burns 0.8g of iron in oxygen
the iron reacts to form 1.1g of iron oxide
Therefore the mass of oxygen can be calculated by subtracting the mass of iron in oxygen from the mass of iron
= 1.1 - 0.8
= 0.3g
Hence the mass of oxygen that reacted with the iron is 0.3g

How many moles do you have if you have 8.03 x 1023 atoms of oxygen?
Answers
Answer:
The answer is 1.33 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\ [/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{8.03 \times {10}^{23} }{6.02 \times {10}^{23} } \\ = 1.33388704...[/tex]
We have the final answer as
