The information about the rate of decay reaction relative to the concentration of oxygen is the reaction occurs more slowly when there is less oxygen.
What is decay reaction?
Radioactive decay reaction is that reaction in which the nucleus of an element emit radiation and energy and transformed into another nuclei with less mass and energy.
Thus, the correct option is C, the reaction occurs more slowly when there is less oxygen.

Consider the following diagram of a chemical reaction.
A series of four increasingly more complex chemical structures. The first diagram shows that when heat is applied to R single bond O single bond O single bond R, it creates 2 R single bond O with 1 electron dot. The next structure brings in more complex structures and other atoms, such as H and C. This process continues until the final molecule has a long chain of six starting with R O and ending with C with a single electron dot. There are four single side chains, 3 P h and 1 H.

Step 1: Given data
Concentration of the concentrated solution (C₁): 8.9 MVolume of the concentrated solution (V₁): 76 mLConcentration of the diluted solution (C₂): ?Volume of the diluted solution (V₂): 171 mLStep 2: Calculate the concentration of the diluted solution
We can calculate the concentration of the diluted solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂
C₂ = 8.9 M × 76 mL/171 mL = 3.96 M

There are 4.67 * 10 ^ 24 hydrogen gas molecules the react with 21.0 Liters of oxygen gas STP conditions to form water. How many grams of water will form? How many moles of the excess reactant will remain after the reaction is completed?
Answers
Answer:
I am almost done
Explanation:
21.0 L
↓
2H₂(g) + O₂(g) → 2H₂O(l)
↑
4.67 × 10²⁴ moles
[This is done so the equation is balanced and the reaction can occur]
[subscripts are the number of atoms, and the coefficients are the number of molecules]
______________
Since there are about 6.02 × 10²³ moles in one mol of a substance.
4.67 × 10²⁴ / 6.02 × 10²³ =
7.7547174437 mol.
Next, we must determine the grams per mole of each substance, this can be done with the periodic table.
Since hydrogen, and oxygen gas are diatomic, they will consist of two atoms each. So the atomic mass will be multiplied by 2 to get the molecular mass. Therefore H₂ will have a molecular mass of 1.00794 × 2 = 2.01588 g/mol.

In this case, since the frequency, velocity and wavelength are related via:

Whereas c is the velocity, lambda the wavelength and f the frequency. Thus, we plug in the given data to obtain:

Answers
Answer:
446 mmHg
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 871 mmHg
Partial pressure of He (Pₐ) = 281 mmHg
Partial pressure of N₂ (P₆) = 144 mmHg
Partial pressure of O₂ (P꜀) =?
The partial pressure of O₂ can be obtained as follow:
Pₜ = Pₐ + P₆ + P꜀
871 = 281 + 144 + P꜀
871 = 425 + P꜀
Collect like terms
P꜀ = 871 – 425
P꜀ = 446 mmHg
Therefore, the partial pressure of O₂ in the mixture is 446 mmHg
