1. Cl electron configuration: 1s^2 2s^2 2p^6 3s^2 3p^5
Ag electron configuration: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^9
2. It will be easier to remove beryllium's valence electrons. Beryllium has two valence electrons, while oxygen has six valence electrons. This means that oxygen has a greater attraction on its electrons because the protons and electrons are closer together. Moreover, during bonding, beryllium is more likely to form the cation Be^2+ and oxygen is more likely to form the anion O^2-. This shows that due to beryllium's weaker attraction, it is more likely to get its electrons taken away than oxygen is.
Explanation:
1. Complete each of the orbitals up to each of the desired elements. Look up a diagram showing the electron shells of the periodic table and count the electrons of each element to be able to solve any configuration problem.
Another way of writing the answer would be in noble gas configuration. This would change the answer to:
Cl: [Ne] 3s^2 3p^5
Ag: [Kr] 5s^2 4d^9
But both answers (the extended electron configuration and the noble gas configuration) mean the same thing.

Work = Force X Distance A dog pulls a ball with 5N of force for 4 m. How
much work did the dog do?*
Answers
Answer:
W = 20 J
Explanation:
Given that,
The force acting on the dog, F = 5 N
Distance covered, d = 4 m
We need to find the work done by the dog. The work done by an object is given by :
W = Fd
Put all the values,
W = 5 N × 4 m
W = 20 J
So, 20 J of work is done by the dog.

Based on Avogadro's principle, the coefficients in chemical equations involving only gases
represent two types of quantities. Name the two quantities.
Explanation:
Answer: Molar ratio is the quantity which will correctly convert between two different substances.
Answer: Option B
Explanation:
Molar ratio is used to determine the number of moles of reactants required to convert to desired number of moles of the products and vice versa. As moles are the coefficient written in any chemical equation. The ratio of the number of moles of the reactants to the number of moles of the products will help to determine the molar ratio.
This molar ratio is used as the conversion factor to determine number of moles required in the reactant side for the reactants to form a desired product of desired moles. We can also determine the number of moles utilized from the reactants from the moles obtained in the products using this molar ratio conversion factor.

1) What volume of 0.25M lithium fluoride solution can be made by dissolving 5.0 g lithium fluoride, LiF?
Answers
Answer:
0.7712 L
Explanation:
Molarity = 0.25M
Volume = ?
Mass = 5.0 g
The relationship between these quantities is given as;
Molarity = Number of moles / Volume
Volume = Number of moles / Molarity
Number of moles = Mass / Molar mass
Molar mass of LiF = 25.939 g/mol
Number of moles = 5 / 25.939 = 0.1928 mol
Volume = 0.1928 / 0.25 = 0.7712 L

2. How many grams of methane must be burned to produce 2.05 grams of water in the complete combustion reaction?
The unbalanced equation for the reaction is: _CH418) + _ 0218) ►_CO2(8) +_ H2O(8)
Answers
Answer:
0.88 g
Explanation:
The balanced reaction equation is;
CH4(g) + 2O2(g) ----------> CO2(g) + 2H2O(l)
Number of moles in 2.05g of water = 2.05g/18g/mol = 0.11 moles
If 1 mole of CH4 yields 2 moles of water
x moles of CH4 yields 0.11 moles of water
2x = 0.11
x = 0.11/2
x= 0.055 moles
Molar mass of methane = 16 g/mol
Mass of methane = 16 g/mol * 0.055 moles
Mass of methane =0.88 g

Which has a lower electronegativity and why? N or P? Use 'force of attraction' in your answer
Answers
Answer:
The electron sets divided among two particles are not really shared similarly. For instance, while the common electron sets are shared similarly in the covalent security in Cl2, in NaCl the 3s electron is taken from the Na iota and is fused into the electronic design of the Cl molecule - and the compound is most precisely portrayed as comprising of individual Na+ and Cl− particles (ionic holding). For most covalent substances, their bond character falls between these two limits. We showed beneath, the bond extremity is a helpful idea for portraying the sharing of electrons between molecules inside a covalent bond:
A nonpolar covalent bond is one in which the electrons are shared similarly between two particles.
A polar covalent bond is one in which one iota has a more noteworthy fascination for the electrons than the other molecule. On the off chance that this overall fascination is sufficiently incredible, the bond is an ionic bond.

A large piece of iron was reacted with an acid. What would happen to the rate of the reaction had the large piece been finely divided into smaller pieces? (1 point)
It will decrease because the reactant particles are moved farther apart.
It will increase because the reactant particles are brought closer together.
It will decrease because larger particles provide more surface area to react.
It will increase because smaller particles provide more surface area to react.
Answers
Answer:
D: It will increase because smaller particles provide more surface area to react.
Explanation:
When the large iron is broken up into smaller pieces, there are more places for the iron to react (meaning there's more surface area). Think of it like taking the surface area of a big cube compared to the surface area of a bunch of small cubes. The sum of the surface areas of the small cubes will be greater than that of the large cube. As a result, more places for the iron to react will cause for a greater reaction.
Answer: D It will increase because smaller particles provide more surface area to react.
