Option (a) Ca, Mn, Co are paramagnetic elements in the fourth period of the periodic table due to unpaired electrons.

A substance's electron configuration can be used to assess if it has magnetic properties: The material is paramagnetic if any of its electrons are unpaired, and it is diamagnetic if all of its electrons are paired.

Materials with hindered electrons that are drawn to magnetic fields are considered to be paramagnetic. In the absence of a magnetic field, they become less magnetic. The magnetic moment of the material and, consequently, the paramagnetism, increase with the number of unpaired electrons.

Mn^{2+} is the ion with the most paramagnetic behaviour because it has the most unpaired electrons when two electrons are lost.

In this instance, calcium is a paramagnetic element as well. This is an anomaly. Due to the ability of one of calcium's electrons in the S orbital to jump to the D orbital, the element is paramagnetic. Since calcium is in Period 4, its D orbital is unoccupied. D orbitals exist in elements with period 4. Thus, this provides that electron with a destination.

Three electrons are not paired in cobalt. It is hence paramagnetic. Three unpaired electrons are present in the outermost subshell.

suppose a student poured equal volumes of water and naoh in two different flasks. he forgets to label his flasks and is confused
ArbitrLikvidat [17]

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.

Convert 1.7 Kg to cg
Kipish [7]
To answer this lets first see how much 1 kg is equal to in cg.

1 kg = 100000 cg 

Now lets multiply:-

100000 × 1.7 =  <span>170000
</span>
So, 1.7 kg = <span>170000 cg
</span>
