Explanation:
hope this helps:)
According to the research, electrons are the part of the atom that is involved in chemical reactions.
What are electrons?It is a subatomic element that is located around the nucleus of the atom, formed by neutrons and protons and is the lightest essential particle that makes up an atom.
In chemical reactions reagents or reactants are involved, specifically in oxidation-reduction reactions electrons are transferred between chemical species, the oxidizing substance loses electrons and the other gains electrons.
Therefore, we can conclude that according to the research, electrons are the part of the atom that is involved in chemical reactions.

Which has the larger radius, F or F− ?
A. They have the same radius.
B. F
C. F−
D. It is impossible to tell.
Answer is B- F has a smaller radius than F− because an additional electron causes greater repulsion in F− is the correct choice and the nuclear charge the radius of the anion increases.
Explanation: I hoped that helped!
The one that have larger radius is F-. The correct option is C.
What is atomic radius?A chemical element's atomic radius is a measurement of the size of its atom, usually the mean or typical distance from the nucleus's center to the outermost isolated electron.
Because a boundary is not a well-defined physical entity, various non-equivalent definitions of atomic radius exist.
As the number of energy levels decreases down a group, the distance between the nucleus and the outermost orbital increases.
As a result, the atomic radius expands. The ionic radius is the distance between the nucleus and the ion's electron cloud's outer edge.
Because they have fewer shells, F and F- are both smaller than the rest. F- now has one more electron than F, causing the radius to increase.
Thus, the correct option is C.

Ammonia (NH3) is widely used as a fertilizer
and in many household cleaners. How much
ammonia is produced when 3.55 mol of hydrogen gas react with an excess of nitrogen
Answer:
Mass of ammonia produced = 40.29 g
Explanation:
Given data:
Number of moles of H₂ = 3.55 mol
Mass of ammonia produced = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Now we will compare the moles of ammonia with hydrogen
H₂ : NH₃
3 : 2
3.55 : 2/3×3.55 = 2.37 mol
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 2.37 mol × 17 g/mol
Mass = 40.29 g

What would you need to do to calculate the molality of 10 mol of NaCl in 200
mol of water?
A. Convert the 200 mol of water to kilograms of water.
B. Convert the 200 mol of water to liters of water.
C. Convert the 10 mol of NaCl to grams of NaCl.
O D. Convert the 10 mol of NaCl to kilograms of NaCl.
SUBMIT
Answer:
A. Convert the 200 mol of water to kilograms of water.
Explanation:
To find the molality of 10mol of NaCl in 200mol of water, convert the 200mol of water to kilograms of water.
Molality is one of the several ways of measuring concentration of a solute in a solvent;
Molality = [tex]\frac{number of moles of solute}{mass of solvent}[/tex]
To solve this problem, simply convert the 200mole to mass of water.how many moles of N2O5 are produces by reacting 10 moles of O2?
Answer:
4 moles of N₂O₅
Explanation:
Given parameters:
Number of moles of O₂ = 10moles
Unknown:
Number of moles of N₂O₅ produced = ?
Solution:
To solve this problem, we must write the reaction equation first,
2N₂ + 5O₂ → 2N₂O₅
IN the reaction above;
5 moles of O₂ will produce 2 moles of N₂O₅;
10 mole of O₂ will produce [tex]\frac{10 x 2}{5}[/tex] = 4 moles of N₂O₅

Answer:
C
Explanation:
Cyanide's formula can be found either on google on on a reference table at the "polyatomic ions" table. Hydrogen, H, has a charge of 1+ when bonded, and cyanide has a charge of 1- overall, so they will be in a one to one ratio while bonded. As such, the equation is HCN.
