The result is quikline or calcium oxide I think I'm not sure tho so I'd still double check
The weight of 98kg is 216.053 pounds.
C. Convection cells
<u>Explanation:</u>
<u></u>
Mantle convection is the moderate crawling movement of Earth's strong silicate mantle brought about by convection flows conveying heat from the inside to the planet's surface. Mantle convection, is a significant technique for heat transport inside the Earth. Mantle convection is the driving component for plate tectonics, which is the procedure eventually liable for delivering tremors, mountain ranges, and volcanoes on Earth. During the movement of warm and cooler mantle rocks, convention cells are created which acts as a pocket that creates force for the movement of tectonic plates.

<h2>Changes Occurs when a Barium Atom - Option 3 </h2>
When a barium atom loses two electrons it becomes a positive ion and its radius decreases. Barium (Ba) has atomic number 56 so it has 2 electrons in first shell of an atom to become stable according to duplet rule. Then other 52 electrons revolve in the shells according to octet rules.
Another 2 electrons are in the outermost shell. To become stable electrons lose to form barium ions (Ba+2). Hence, by losing 2 electrons the outermost shell will be diminished so its radius decreases and by losing electrons it becomes positive ions.
