Answer:
Not all conflicts are harmful to an organization
Explanation:
Not all conflicts in an organization are harmful to that organization.
Conflicts can be good for an organization. Even though conflicts may always seem difficult, they could bring about growth and changes which are good for all organizations.
Conflict may have positive or negative results when they occur. How these conflicts are approached is what determines the result.
Positive conflict can be constructive, it births new ideas, gives opportunities for creativity and skills expansion and can solve continuous problems.
1p is not possible because it goes like this 1s2 2s2 2p6
The answer is the mass will change by 2 grams with the ballon on top
Answer 1) Option D) 3 moles.
Explanation : In the reaction we can see that the number of moles of hydrogen are equal to the number of water molecules formed. Also, oxygen is found t o be the limiting reactant as equal number of moles are not produced in the reaction.
Here when we use 3 moles of hydrogen then 3 moles of water will be produced. As we are ignoring the moles of oxygen here as that is a limiting reactant.
Answer 2) Option A) 9 moles of reactants chemically change in to 11 moles of product.
Explanation : We can see that 1 mole of pentane reacts with 8 moles of oxygen to produce 5 moles of carbon dioxide and 6 moles of water. So when we add the reactants side we get 1 + 8 = 9 moles and in products it has 5 + 6 = 11 moles.
Hence, 9 moles of reactants produce 11 moles of products.
Answer 3) Option A) 0.62 moles.
Explanation : Here, the number of moles of Cu reacts with 2 moles of silver nitrate and gives 1 mole of copper nitrate and 2 moles of silver.
So, the ratio is 1 : 2 in the reactants side, Now, when we have 1.23 moles of silver nitrate then to calculate the number of Cu.
we can simply cross multiply and get the answer as 1.23 / 2 = 0.615 = ~ 0.62 moles.
