Given :
Initial concentration of nitric acid, 
.
Final concentration of nitric acid, 
.
Volume of 
, 
To Find :
Volume needed( 
).
Solution :
We know,
Hence, this is the required solution.
Endothermic reactions are reactions that require heat in the course of the process. The heat of reaction in this case is positive which means the energy of the products is greater than the energy of the reactants. In this case, the answer to this problem would have to be <span>1. must be greater than the required ΔH </span>
Answer:
One electron is present in 4p energy sublevel.
Explanation:
Gallium element has symbol Ga with atomic number 31.
It is placed in group 13 and fourth period in the modern periodic table.
The electronic configuration of the element, gallium is -
As seen, from the configuration,
<u>One electron is present in 4p energy sublevel.</u>
Hey there!
Compounds with ionic bonds have higher melting points because of the forces needed to break through the strong forces of attraction holding it together.
Compounds with covalent bonds have lower melting points because less energy is needed to break the weaker forces of attraction.
So, your answer is C. Compound 1 is ionic, and compound 2 is molecular.
Hope this helps!
Observation is acknowledging and noting some facts from the surroundings or the environment. Usually, observation is done using the five senses of human such as the sense of sight, sense of smell, sense of touch, sense of hearing and sense of tasting. It can also be qualitative and quantitative. Qualitative observations are those who use non-numeric forms in expressing the observation however quantitative uses numeric forms in presenting the observation. Inference on the other hand is the probable explanation or interpretation based on the observation given. Therefore, the statement "The container is filled to the 350 ml mark with water " is an observation.
