Select the most likely product for this reaction:
KOH(aq) + CO2(g) – ?
K2CO3(aq) + H2O(1)
K(s) + H2(g) + O2(g)
K(s) + CO3(9) +H2
Answer:
K2CO3(aq) + H2O(l)
Explanation:
Balance the equation
2KOH(aq) + CO2(g) ------ K2CO3(aq) + H2O(l)
Answer:
K2CO3(aq) + H2O(1)
Explanation:
KOH(aq) + CO2(g) is an acid-base reaction.
KOH is a known base and CO2 is a known acidic gas. It dissolves in water to give a solution whose pH is less than 7.
The normal products of a neutralization process is the salt and water. Hence, this neutralization process isn't any different. Salt, in the form of K2CO3, and water, H2O is the result of this reaction.

Among the following, which atom is most likely to form an ion with a charge of 2+?
Ca
Al
Na
O
Calcium (Ca) is the atom that most likely forms a 2+ ion, due to its position in group 2 of the periodic table, which defines it as an alkaline earth metal.
Among the following, the atom most likely to form an ion with a charge of 2+ is Ca (Calcium). Calcium belongs to the alkaline earth metals (group 2) in the periodic table and tends to lose two electrons to form a cation with a 2+ charge, becoming Ca2+. This ion has 20 protons and 18 electrons, having the same number of electrons as an atom of the preceding noble gas, argon.

5. What is the mass of 9.80 x 1023 formula units of zinc chlorate, Zn(CO3)2?
Answer:
[tex]\boxed{\text{378 g}}[/tex]
Explanation:
We must convert formula units of Zn(ClO₃)₂ to moles and then to grams of Zn(ClO₃)₂.
Step 1. Convert formula units to moles
[tex]\text{Moles of Zn(ClO$_{3}$)$_{2}$}\\\\= 9.80 \times10^{23}\text{ formula units Zn(ClO$_{3}$)$_{2}$} \times \dfrac{\text{1 mol Zn(ClO$_{3}$)$_{2}$}}{6.022 \times\ 10^{23} \text{ formula units Zn(ClO$_{3}$)$_{2}$}}\\\\= \text{1.627 mol Zn(ClO$_{3}$)$_{2}$}[/tex]
Step 2. Convert moles to grams
[tex]\text{Mass of Zn(ClO$_{3}$)$_{2}$}\\\\= \text{1.627 mol Zn(ClO$_{3}$)$_{2}$} \times \dfrac{\text{232.29 g Zn(ClO$_{3}$)$_{2}$}}{\text{1 mol Zn(ClO$_{3}$)$_{2}$}}\\\\= \text{378 g Zn(ClO$_{3}$)$_{2}$}\\\\\text{The mass of Zn(ClO$_{3}$)$_{2}$ is } \boxed{\textbf{378 g}}[/tex]
To find the mass of 9.80 x 10^23 formula units of zinc chlorate, the molar mass of the compound must be determined using atomic masses, then this mass is compared to Avogadro's number to find the proportionate mass.
Explanation:The mass of 9.80 x 1023 formula units of zinc chlorate can be calculated using Avogadro's number and the molar mass of zinc chlorate, Zn(CO3)2. First, we must find the molar mass of zinc chlorate by adding the atomic masses of the zinc atom, two chlorine atoms, and six oxygen atoms. Using the periodic table, we can determine this value (not provided in the question, so you will need to calculate it yourself). Then, to find the mass of 9.80 x 1023 formula units, we use the ratio of 1 mole being equivalent to 6.022 x 1023 formula units.
If 1 mole of zinc chlorate weighs the calculated molar mass and corresponds to 6.022 x 1023 formula units, we can set up a proportion to calculate the mass of 9.80 x 1023 formula units:
Molar mass of Zn(CO3)2 / 6.022 x 1023 = Desired mass / 9.80 x 1023
After cross-multiplying and solving the equation, we obtain the desired mass of zinc chlorate. It is important to note that the student should verify the molar mass of zinc chlorate themselves, as the information is not specified in the question's context.

If the pH of a solution is 7.6, what is the pOH?
Answer:
6.4
Explanation:
PH +POH=14
POH=14-7.6
=7.6
The pOH of a solution with a pH of 7.6 is 6.4, which indicates that the solution is slightly basic.
If the pH of a solution is 7.6, to find the pOH, we use the relationship:
pH + pOH = 14
Given that the pH is 7.6, we subtract this from 14 to find the pOH:
pOH = 14 - pH
pOH = 14 - 7.6
pOH = 6.4
Therefore, the pOH of the solution is 6.4, indicating that the solution is slightly basic, because a pOH of less than 7 signifies a basic solution.
