The right answer for the question that is being asked and shown above is that: "<span>2)A gas forms, and there is a change of color. " </span>During an experiment, a student observes the formation of a precipitate. a chemical reaction is likely occurring because <span>A gas forms, and there is a change of color.</span>
The answer is it shifts right. This could be explained by Le
Chatelier's principle. It states that that when a system experiences a commotion
(such as absorption, temperature, or heaviness variations), it will answer to reinstate
a new equilibrium state. This just means that if there is an energy added, the
reaction is trying to remove it again by going to the right.
Answer:
They are listed below
Explanation:
The 5 things that the periodic table includes are;
1. Name of the element
2. The symbol of the element
3. Atomic number of the element
4. Relative atomic mass
5. Electron configuration
Most transition metal form more than one cation but aluminum forms the Al3+ cation only.
The Lewis Structure of HCN is shown below,
Number of Bonding Electrons: In HCN Hydrogen is bonded to Carbon through single bond and Nitrogen is bonded to Carbon through Triple Bond. Single bond is formed by two bonding electrons, while, triple bond is formed by six bonding electrons, Hence,
Number of Bonding Electrons = 8
Number of Non-Bonding Electrons:
In HCN there is only one lone pair of electron present on Nitrogen atom which is not taking part in bonding. Hence,
Number of Non-Bonding Electrons = 2
Result: Number of Bonding Electrons = 8 Number of Non-Bonding Electrons = 2
