The order of strongest to weakest bond type:
Ionic bond > Polar covalent bond > non polar covalent bond
Explanation:
Ionic bonds are chemicals bonds in which the complete transfer of electrons takes place between a highly electronegative atom and the least electronegative atom.In an ionic bond, there is a strong electrostatic force of attraction due to the formation of two oppositely charged ions.Covalent bonds are chemicals bonds in which the sharing of electrons takes place between atoms with a slight or nil difference in their electronegativities.There are two types of covalent bonds: polar covalent and nonpolar covalent.In polar covalent bonds, due to unequal sharing of electrons partial positive and negative charges are generated.These partial charges give rise to a temporary attractive force of attraction between atoms in polar covalent bonds.In non-polar covalent bonds, equal sharing of electrons between atoms of the same or similar electronegativities.The order from strongest to weakest chemical bond:Strong electrostatic force> temporary attractive force> no force of attraction
Ionic bond > Polar covalent bond > non polar covalent bond
So, from this, we can conclude that the order of ionic bond is the strongest followed by a polar covalent bond and then a nonpolar covalent bond.

3. Nicole plans an investigation to determine the Sun's role in the water cycle. She
places a tomato plant in the sunshine and one in a darkened room. She puts a clear
plastic bag around a leaf on both plants. She waters the plants daily with the same
amount of water. After two days, she notices that there are water droplets on the
inside of the plastic bag on the plant that is in the sunshine. What part of the water
cycle does her experiment show?
A.
B.
It shows how sunlight triggers infiltration in the plant.
It shows how sunlight triggers evaporation in the plant.
It shows how sunlight triggers precipitation in the plant.
It shows how sunlight triggers transpiration in the plant.
C.
D.
Answer:
It shows how sunlight triggers transpiration in the plant.
Explanation:
The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves are known as transpiration.

Three common gaseous compounds of nitrogen and oxygen of different elementary composition are known: (A) laughing gas containing 63.65% nitrogen, (B) a colorless gas containing 46.68% nitrogen, and (C) a brown toxic gas containing 30.45% nitrogen. Show how these data illustrate the law of multiple proportions.
Answer:
Please find how these data prove the law of multiple proportions below
Explanation:
The law of multiple proportions was proposed by an English chemist called John Dalton. The law states that when two elements combine and to form more than one compound. The weights/masses of the second element in the two compounds, which combines with a fixed ratio of the first element, is in a simple whole number ratio.
In this question, Nitrogen is said to combine with oxygen to give three different compounds as follows:
A) laughing gas containing 63.65% nitrogen i.e. 0.6365g
This means that the mass of oxygen will be (1-0.6365) = 0.3635g
B) colorless gas containing 46.68% nitrogen i.e. 0.4668g
This means that the mass of oxygen will be 0.5332g
C) brown toxic gas containing 30.45% nitrogen i.e. 0.3045g
This means that the mass of oxygen will be 0.6955g
The ratios of oxygen in the three compounds is therefore:
0.3635: 0.5332: 0.6955
Divide this ratio by the smallest number (0.3635)
0.3635/0.3635 = 1
0.5332/0.3635 = 1.467
0.6955/0.3635 = 1.913
Multiply this ratio by 2, we have:
2: 2.9 : 3.8
Hence, the simple whole number ratio is 2:3:4.
This proves the law of multiple proportions that oxygen is in simple whole number ratio in the three different compounds.

In a 5.609g of H20, how many molecules H20
arc
present?
Answer:
1.88 x 10²³molecules of H₂O
Explanation:
Given parameters:
Mass of H₂O = 5.609g
Unknown:
Number of molecules of H₂O = ?
Solution:
To solve this problem, we need to find the number of moles of given compound first.
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Number of moles = [tex]\frac{5.609}{18}[/tex] = 0.31mole
From mole concept;
1 mole of a substance contains 6.02 x 10²³molecules
0.31 mole of H₂O will therefore contain 0.31 x 6.02 x 10²³molecules
= 1.88 x 10²³molecules of H₂O

If 4 moles of O2 and 8 moles of N2 occupy a 12 L
container at a pressure of 6 atm, what is the partial
pressure of N2?
Answer:
P(N₂) = 4.02 atm
Explanation:
Number of moles of O₂ = 4 mol
Number of moles of N₂ = 8 mol
Total pressure = 6 atm
Partial pressure of N₂ = ?
Solution:
We will calculate the partial pressure by using mole friction.
P(N₂) = X(N₂)P(total)
X(N₂) = mol friction = moles of N₂ / total number of moles
X(N₂) = 8 mol / 12 mol = 0.67
Partial pressure of N₂:
P(N₂) = X(N₂)P(total)
P(N₂) = 0.67 × 6 atm
P(N₂) = 4.02 atm
