Answer:
Fluorine. This element has the greatest electronegativity value, so has the greatest attraction to electrons in a bond.
Explanation:
The atom of element with the strongest attraction for electrons in a chemical
bond from the options is Chlorine.
The element with the strongest attraction for electrons in a chemical bond is
the most electronegative element.
The electronegativity of an atom is the tendency of an atom to attract
bonding pairs of electrons.
Generally, electronegativity of an element increases across the period. The
electronegativity of an element also decreases down the group. The most
electronegative element is fluorine.
Halogen group are naturally electronegative.
Therefore, the most electronegative element in the option is chlorine and its
the element that has the strongest attraction for electrons in a chemical
bond.

Which of these expressions are correct variations of the Combined Gas Law?
Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
[tex]\frac{P_{1}V_{1} }{T_{1} }[/tex] = [tex]\frac{P_{2}V_{2} }{T_{2} }[/tex]
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ = [tex]T_{2} \frac{P_{1}V_{1} }{P_{2} V_{2} }[/tex]
Also;
V₂ = [tex]V_{1} \frac{P_{1} T_{2} }{P_{2} T_{1} }[/tex]
So from the choices both are correct
If an object has a 30 kg mass on Earth, what would be it's approximate weight on Earth?
Answer:
If something were to weigh 30 kgs on Earth, they would also weigh around 66 pounds on Earth.
Explanation:
1 pound = 2.20462 kilograms.
Next, multiply 2.20462 and 30 and you should get 66.1386, or 66 pounds.

Calculate the volume of a sample of aluminum that has a mass of 3.057 kg. The density of aluminum is 2.70 g/cm3 (taking into consideration the rounded to three significant figures)
Answer:
v = 1130 cm³
Explanation:
Given data:
Volume of sample = ?
Mass of Al sample = 3.057 Kg (3.057 Kg× 1000g/1 Kg = 3057g)
Density of Al sample = 2.70 g/cm³
Solution:
Formula:
d = m/v
d = density
m = mass
v= volume
by putting values
2.70 g/cm³ = 3057g /v
v = 3057g /2.70 g/cm³
v = 1130 cm³

A chloroplast converts energy from sunlight into organic matter.
Mitochondria change energy stored in organic compounds into a
usable form. the two statements are ways in which cells get nutrients.
Proteins embedded in the cellular membrane act as ushers. They help carry nutrients from the bloodstream into the cell. Glucose, amino acids, fats, and vitamins use carrier proteins to get inside cells.Onice through the membrane, nutrients play many important roles. Some cells, like muscle fibers, need minerals like calcium to flood the cell to move your arms and legs. Others, like nerve cells, need sodium and potassium to be pumped in and out so your brain can pick up sensory information.Cells use the glucose in your bloodstream to create energy by making ATP, the cellular energy currency. And amino acids are the building blocks for all DNA. When they’re brought into the cell, amino acids help transfer genetic information so cells can replicate.Learn more about cells get nutrients

Carbon powder and iron fillings are both black powders. When mixed together they look like one black powder. Which of these would be best to use to seperate the iron fillings from the carbon powder. A. a magnifying glass B. heat C. a magnet D. water
Answer:
C
Explanation:
The iron filings will be attracted to the magnet and will separate from the carbon powder.
The best method to be used to separate the iron fillings from the carbon powder is through the use of water.
The separation of carbon powder and iron fillings in powdered form can be achieved in a blast furnace flue dust. The blast furnace flue dust is usually combined with water to create a slurry that contains (50-70)% solids.
The slurry is fortified with a flotation agent as well as a frothing agent. The content in the slurry is stirred rapidly to cover the carbon particles completely with the flotation agent.
The carbon powdered particles float on top of the slurry, while the iron fillings are collected as a sink product.
