Answer:
12 H, 18 O, 6 C
Explanation:
[tex]6H_{2} O + 6CO_{2} -- > C_{6}H_{12} + 6O_{2}\\[/tex]
___________________
first, we'll fo the h on the first equation: [tex]6H_{2}[/tex]
multiply the 6 and 2 to get twelve.
in the second equation, we see that there is [tex]H_{12}[/tex]
so, in both there are 12 H.
__________________
Now we'll do O.
in the first equation we have [tex]6O + 6O_{2}[/tex]
so we have 6 + (6*2) or 6 + 12, which gives us 18
in the second equation we have [tex]O_{6} + 6O_{2}[/tex]
it's basically the same thing, just written differently, so we have 18.
__________________
Finally, C.
In the first equation, we have [tex]6C[/tex]
in the second [tex]C_{6}[/tex], again, same thing expressed differently.
both have 6 C.

The correct equilibrium constant expression for the given chemical reaction is Keq = [Cu²⁺] / [Ag⁺]².
What is equilibrium constant?Equilibrium constant of any reaction at the equilibrium state will be define as the ratio of the concentration of products to the concentration of the reactants.
Given chemical reaction is:
Cu(s) + 2Ag⁺(aq) ⇄ Cu²⁺(aq) + 2Ag(s)

What is equilibrium?When the observable qualities, such as colour, pressure, temperature, concentration, etc. do not vary, the process is said to be in equilibrium. As "balance" is the definition of the word "equilibrium," it follows because a chemical reaction reflects a balance among the substances and outcomes involved in the reaction.
In some physical processes, such as the melting of ice at 0°C, where both the two substances are present at equilibrium, the equilibrium state can also be observed. Physical equilibrium refers to the equilibrium that results from physical processes like the melting of solids. [NOBr]2/[NO]2[Br2] is the equilibrium expression for 2NO+Br2⇌2NOBr.

if 66.38 g of potassium chloride reacts with fluorine and produces potassium fluoride and chlorine how many moles of chlorine can you get?
Answers
Taking into account the reaction stoichiometry, f 66.38 g of potassium chloride reacts with fluorine and produces potassium fluoride and chlorine, 0.4452 moles of chlorine is produced.
Reaction stoichiometryIn first place, the balanced reaction is:
2 KCl + F₂ → 2 KF + Cl₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
KCl: 2 moles F₂: 1 moleKF: 2 moles Cl₂: 1 moleThe molar mass of the compounds is:
KCl: 74.55 g/mole F₂: 38 g/moleKF: 58.1 g/moleCl₂: 70.9 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
KCl: 2 moles ×74.55 g/mole= 149.1 grams F₂: 1 mole ×38 g/mole= 38 gramsKF: 2 moles ×58.1 g/mole= 116.2 gramsCl₂: 1 mole ×70.9 g/mole= 70.9 gramsMoles of Cl₂ formedThe following rule of three can be applied: if by reaction stoichiometry 149.1 grams of KCl form 1 mole of Cl₂, 66.38 grams of KCl form how many moles of Cl₂?
[tex]amount of moles of Cl_{2} =\frac{66.38 grams of KClx1 mole of Cl_{2}}{149.1 grams of KCl}[/tex]

Explain in terms of atomic structure why barium has lower first ionization energy than magnesium
Answers
Answer:
Barium is lower in group 2 than magnesium, so number of shells increase. The valence electron is further from the nucleus making it easier to lose electrons.
Explanation:
Barium has more electrons shells than calcium, so the nuclear shielding is stronger, and the outmost electrons are further away from the nucleus. This results in a weaker attractive force between the electron and the nucleus, so a smaller energy is required to remove it.
Answer:
Barium has a greater radius than magnesium
Explanation:
Barium and magnesium are two elements which belong to the same group, group 2A. This means that the two elements have two valence electrons in their outer shell.
The difference is, however, since barium
is lower in group than magnesium, it has
more electron shells than magnesium and,
therefore, its radlus is greater. The attraction
force between the nucleus and the valence
electrons in barium is lower as a result, as force
is inversely proportional to distance. Hence, a
lower amount of energy is required to remove
the valence electrons from barium.
