Answer:
4d orbital.
Explanation:
Hello!
In this case, since zirconium's atomic number is 40, we fill in the electron configuration up to 40 as shown below:
Thus, the orbital 4d is partially filled.
Best regards!
The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.
<h3>
What is volume?</h3>
Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.
Volume is measures in litres.
When water is added to dilute acid like HCl, they become more dilute.
When NaOH is added to HCl, a neutralization reaction occurs.
The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.
The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.

Answer:
Catalysts
Explanation:
Catalysts lower the aviation energy.
Answer:
Examples of substances insoluble in water: oil, acetone, ether
Explanation:
Such examples of substances are non-polar and do not dissolve in water (polar compound). The classic example is oil floating in water (this happens because oil has a lower density than water).
Answer:
The transition which is associated with the greatest energy change is from n=1 to n=3.
Explanation:
where,
= energy of orbit
n = number of orbit
Z = atomic number
Energy of n = 1 in an hydrogen like atom:
Energy of n = 2 in an hydrogen like atom:
Energy of n = 3 in an hydrogen like atom:
Energy of n = 5 in an hydrogen like atom:
1) Energy change transition from n = 1 to n = 3 occurs .
Let energy change be E.
(absorption)
2) Energy change transition from n = 2 to n = 1 occurs .
Let energy change be E.
(emission)
3) Energy change transition from n = 3 to n = 2 occurs .
Let energy change be E.
(emission)
4) Energy change transition from n = 3 to n = 5 occurs .
Let energy change be E.
(absorption)
Highest magnitude of energy corresponds to the greatest energy change.So,the transition which is associated with the greatest energy change is from n=1 to n=3.
