Answer:
Ionic bonding involves the transfer of electrons from a metal atom to a non-metal atom until the outer shells of their resultant atoms are similar to that of a noble gas. The metals lose electrons and form cations while the non-metals accept the electrons and form anions.
When a chemical bond forms between metal and nonmetal atoms, the nonmetal atom accepts electrons from the metal atom to reach a stable state.
A bond that forms between metal and nonmetal atoms is called an ionic bond. In ionic bonding, the metal atom, the cation, donates electrons to the nonmetal atom, the anion.
Thus, both electron donor and acceptor are able to reach an octet state through donation/acceptance of electrons and an ionic bond is formed as a result.

carbon dioxide and water vapor are variable gases because
Answer:
Their amount is not consistent at all parts of the atmosphere
Explanation:
Carbon dioxide and water vapor exists as variable gases in the atmosphere because their amount varies from one part to the other.
The abundance of variable gases is influenced strongly by activities from the surface. This variability occurs a result of the contribution from from life activities on the surface. Also, due to properties of the gases, they are not evenly distributed. At certain altitudes, the amount of water vapor can be low.Carbon dioxide and water vapor are variable gases because their amount is not consistent at all parts of the atmosphere.
Surface activities have a significant impact on the abundance of variable gases.This variation arises as a result of the input of surface life activities.They are also not uniformly dispersed due to the characteristics of the gases.Water vapor levels might be low at particular heights.Carbon dioxide and water vapor are variable gases because their amount is not consistent at all parts of the atmosphere.For more information:

An unknown gas has a volume of 20L at 140K. What is its volume at STP? Be sure to show the setup and the final
answer and unit.
Show Your Work
Answer:
v₂ = 39L
Explanation:
Given parameters:
Initial volume of gas = 20L
Initial temperature = 140K
Unknown:
Final volume = ?
Solution:
Since the standard temperature of any gas is 273K, the final temperature is this 273K;
Applying Charles's law:
[tex]\frac{v_{1} }{T_{1} }[/tex] = [tex]\frac{v_{2} }{T_{2} }[/tex]
v and T are volume and Temperature
[tex]\frac{20}{140}[/tex] = [tex]\frac{v_{2} }{273}[/tex]
v₂ x 140 = 20 x 273
v₂ = 39L

In the decomposition reaction, what does the
Δ
symbol represent?
Explanation:
44 gm mass of carbon dioxide is produced by the decomposition.
What is meant by Decomposition reaction?
Chemical species disintegrate into more straightforward components during decomposition events. Energy input is typically required for decomposition reactions.
For instance, the thermal breakdown of potassium chlorate (KClO3) is a typical method for creating oxygen gas in laboratories.
Calculations:
CaCO3 → CO2 + CaO
depending on the conservation of mass
mass of the product = mass of the reactant
100 g = ( X + 56 )
mass of CO2 = 100 - 56
= 44 g
Thus, 44 gm mass of carbon dioxide is produced by the decomposition.

Which statement correctly describes a reaction in dynamic equilibrium? At dynamic equilibrium, the reactions stop and the amounts of reactants and products do not change. At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change. At dynamic equilibrium, the reactions stop but the amounts of reactants and products are changing. At dynamic equilibrium, the reactions continue and the amounts of reactants and products are changing.
Answer:
At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
Explanation:
At dynamic equilibrium, the reactions continue but according to the law of conservation of mass, the amounts of reactants and products don't change.
At dynamic equilibrium, the reactions takes place, however, the amount of reactants and products do not change.
• Dynamic equilibrium prevails once a reversible reaction takes place.
• In this the transition of the substances between the reactants and products takes place at equivalent rates, thus, there is no net change.
• The formation of products and reactants takes place at such a rate that the concentration of both stays the same.
• It is an illustration of a system in steady state, like in a closed system when reactions do take place, however, at such a rate that the composition of the mixture does not varies with time.
Thus, the statement, that is, at dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change is relevant.

Given the speed of light as 3.0 ✕ 108 m/s, calculate the wavelength of the electromagnetic radiation whose frequency is 6.700 ✕ 1012 Hz.
Answer:
Wavelength = [tex]4.48*10^{-5}m[/tex]
Explanation:
Given the following data;
Speed of light, V = 3 * 10^{8}m/s
Frequency, F = 6.700 * 10^{12}Hz.
To find the wavelength
We know that that the speed of light is given by the formula;
[tex] Speed of light, V = wavelength * frequency [/tex]
Making wavelength the subject of formula, we have;
[tex] Wavelength = \frac {speed \; of \; light}{frequency} [/tex]
Substituting into the equation, we have;
[tex] Wavelength = \frac {3 *10^{8}}{6.700 ✕ 10^{12}} [/tex]
Simplifying the equation, we have;
Wavelength = 4.48*10^{-5} m
Therefore, the wavelength of the electromagnetic radiation is [tex]4.48*10^{-5} meters[/tex]

18 g of oxygen reacts completely with 4 g of hydrogen we would expect how many grams of water
A. Less than 22 grams
B. More than 22 grams
C. 22 grams because mass cannot be created or destroyed
D. There is no way to tell by this information
Answer:
C. 22 grams because mass cannot be created or destroyed
Explanation:
In this reaction and in any chemical reaction, mass is expected to always be conserved.
According to the law of conservation of matter "in a chemical reaction, matter is neither created nor destroyed but can be changed from one form to another".
Based on this law, the mass of reactants and products must be the same in a chemical reaction. So, the sum of the mass of the reactants must be equal to the mass of the product.Question 3 of 10
The bonds of the products store 22 kJ more energy than the bonds of the
reactants. How is energy conserved during this reaction?
A. The surroundings absorb 22 kJ of energy from the reaction
system.
B. The reaction uses up 22 kJ of energy when bonds break.
C. The reaction system absorbs 22 kJ of energy from the
surroundings.
D. The reaction creates 22 kJ of energy when bonds form.
Answer: The answer is C. The reaction system absorbs 22 kJ of energy from the surroundings.
Explanation: I just took the quiz and it said I got it right.
As per the law of conservation of energy:
C. The reaction system absorbs 22 kJ of energy from the surroundings
Law of conservation of energy:This law of energy states that the energy remains conserved its neither created nor destroyed. It remains conserved throughout the reaction.
when an amount of heat gets absorbed during the reaction from the surroundings this type of reaction is known as an endothermic reaction.
So, for fulfilling law of conservation, same amount of energy must be asborbed.
Thus, option C is correct.
