Answer:
Argon {Ar}
Explanation:
The noble gas used for a condensed electron configuration is the one before the element which you are configuring.
In this case, the element (Mn) is manganese
The noble gas that is before this element is Argon which is the row above it
so your configuration would be {Ar} 3d^5 4s^2
Answer:
Atomic number of this isotope = 77
Explanation:
Given that,
Mass number = 193
No of neutrons = 116
We need to find the atomic no of this isotope.
We know that,
Atomic mass = No of protons + No. of neutrons
Also, atomic no = no of protons
So,
Atomic mass = atomic no + No. of neutrons
⇒ Atomic no = Atomic mass - no of neutrons
Atomic no = 193 - 116
Atomic no = 77
Hence, 77 is the atomic no of the isotope.
A flowing water model has a flow pattern which is curved, narrow and branching
<h3>What is flowing water?</h3>
Flowing waters means fresh waters flowing unidirectionally down altitudinal gradients.
However, the water may or may not be confined in distinct channels.
Examples of fowing waters includes:
- streams,
- flowing springs,
- seeps,
- ditches,
- flumes.
<h3>Characteristics of water </h3>
Below are some few characteristics of water:
- Water is polar
- Water is an excellent solvent
- Water has high heat capacity
- Water has high heat of vaporization
- Water has cohesive and adhesive properties
- Water is less dense as a solid than as a liquid
So therefore, a flowing water model has a flow pattern which is curved, narrow and branching

I think the correct answer from the choices listed above is option C.
Calcium carbonate = CaCO3
sulfur dioxide = SO2
oxygen = O2
calcium sulfate = CaSO4
Carbon dioxide = CO2
The correct skeleton equation for the reaction would be CaCO3(s)+SO2(g)+O2(g) --> CaSO4(s)+ CO2(g).
