What is the Lewis structure for H2Se

Chemistry
1 answer:
S_A_V [24]3 years ago
6 0
Basically since there’s 2 hydrogen’s there will be two H’s on either side of your other element. And Se is in group 6 which means it has 6 valence electrons. When you combine 6 and 2 from the hydrogen you get 8. You then should place 8 dots around Se two on each side.

So something like H Se(with 8 dogs around it) H

The graph shows the distribution of energy in the particles of two gas samples at different temperatures, T1 and T2. A, B, and C
soldi70 [24.7K]

Based on the information given regarding the energy, the true statement is C.  "The number of particles able to undergo a chemical reaction is less than the number that is not able to."

<h3>What is energy?</h3>

It should be noted that energy is the quantitative property that must be transferred to a body to perform work on the body.

In this case, the graph is shown with two inverted graph curves running close to each other, and one of the curves labeled T1 is slightly more spread out than the other labeled T2.

Here, T1 is the only sample with a particle able to react. Particle B is more likely to participate in the reaction than particle A and the number of particles able to undergo a chemical reaction is less than the number that is not able to.

2_PCl3 + __Cl2 →<br> __PCL5<br> What is the answer
bekas [8.4K]

Answer: 2 PCl3 + 2 Cl2 > 2 PCl5

Explanation: The factors will be 2 moles of PCl3 reacted to 2 moles of chlorine gas Cl2 and the reaction will produce 2 moles of Phosphorous pentachloride PCl5.

For the reactants 2PCl3 +2 Cl2 there will be 2P, Cl (2x3) +

(2x2) so chlorine will have 10. In the product side 2PCl5. 2 P and Cl will have (5x2)=10.

The chemical reaction will have a balance chemical equation.
