<span>The electrons in the outer shell of Xenon are much further away from the nucleus than the electrons in the outer shell of Neon. The Xenon electrons are much less bound to the atom than Neon, and a strong electronegative atom like fluorine succeeds in tearing off an electron.</span>
Your answer would be D, single replacement
Answer:
x = 0.324 M s⁻¹
Explanation:
Equation for the reaction can be represented as:
2 NO(g) + Cl₂ (g) ⇄ 2NOCl (g)
Rate = K [NO]² [Cl₂]
Concentration =
from the question; their number of moles are constant since the species are quite alike.
As such; if Concentration varies inversely proportional to the volume;
we have: Concentration ∝
Concentration =
Similarly; the Rate can now be expressed as:
Rate = K [NO]² [Cl₂]
Rate =
Rate =
We were also told that the in the reaction, the gaseous system has an initial volume of 3.00 L and rate of formation of 0.0120 Ms⁻¹
So we can have:
0.0120 =
0.0120 = -----Equation (1)
Now; the new rate of formation when the volume of the system decreased to 1.00 L can now be calculated as:
x =
x = 1 ------- Equation (2)
Dividing equation (2) with equation (1); we have:
=
=
x = 0.0120 × 27
x = 0.324 M s⁻¹
∴ the new rate of formation of NOCl = 0.324 M s⁻¹
If it takes 35.04ml of a 0.2455M NaOH solution to neutralize 25. 00ml of an unknown HCl solution, the molarity of the HCl solution is 0.34M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = molarity of acid
- C2 = molarity of base
- V1 = volume of acid
- V2 = volume of base
According to this question, it takes 35. 04ml of a 0. 2455M NaOH solution to neutralize 25.00ml of an unknown HCl solution. The molarity of the HCl can be calculated as follows:
35.04 × 0.2455 = 25.0 × V2
8.602 = 25C2
C2 = 8.6/25
C2 = 0.34M
As a result, the molarity of the HCl solution is 0.34M if it takes 35. 04ml of a 0.2455M NaOH solution to neutralize 25ml of an unknown HCl solution.

Answer:
Cells are the "building blocks for all living things." Without cells, we couldn't survive. Cells do many important things. Some of the things they can do are taking in food nutrients, frame our bodies, and change the food nutrients into energy.
