Answer: False
Explanation: The plate tectonics move due to convection currents of the mantle; the cooler upper mantle descends while the hotter lower mantles ascend. The heat that drives these convection currents emanated from the core of the earth (not the sun).
The carbon atom(s) of pyruvate is(are) first converted to carbon dioxide by pyruvate dehydrogenase complex is the second number of carbon of pyruvate goes to oxidation and convert it to CO2 in Krebs cycle.
<h3>what is Krebs cycle ?</h3>
Krebs cycle is also known as citric acid cycle it is the conversion of sugar to the direct energy in the form of ATP which further goes to mitochondria as it is the power house of the human cell.
Pyruvate molecule release second number carbon from the chain and undergoes oxidation to form the CO2.
Therefore, second number carbon atom will converts to carbon dioxide.

Characteristics of Liquids
Liquids have definite volume, but indefinite shape. They are free to form droplets and puddles when they are not inside a container. When a liquid is inside a container, it will take its shape. Unlike gases, a liquid will not change its volume to spread out and completely fill a container.

Answer:
26.899 g of Li
Solution:
The Balance Chemical Equation for given reaction is as follow;
6 Li + N₂ → 2 Li₃N
According to equation,
69.66 g (2 mol) Li₃N is produced by = 41.64 g (6 mol) of Li
So,
45.0 g of Li₃N will be produced by = X g of Li
Solving for X,
X = (45.0 g × 41.64 g) ÷ 69.66 g
X = 26.899 g of Li
Hence, 26.9 g of Lithium is required to produce 45.0 g of Lithium Nitride.
