Answer:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
Answer:
Mass = 217.30 g
Solution:
Mass and moles are related to each other as,
Moles = Mass / M.mass ---- (1)
Where;
Moles = 3.42
M.Mass = 63.54 g.mol⁻¹
Solving eq. 1 for Mass,
Mass = Moles × M.mass
Putting Values,
Mass = 3.42 mol × 63.54 g.mol⁻¹
Mass = 217.30 g
The answer is the fourth choice, or Have membrane-bound organelles. Hope this helps you!

In the equation given above, there is conservation of MASS, CHARGE AND ENERGY.
These three parameters are usually conserved during the course of chemical reactions. When any of these parameter experience a reduction during the course of chemical reaction, such loss is always gained by other elements involved in the same reaction, so that at the end of the day, they are not considered as lost.
The volume at STP : 9.856 L

Given
Mass of ethane : 13.21 g
Required
The volume at STP
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
mol ethane(C2H6) :
= mass : molar mass
= 13.21 g : 30 g/mol
= 0.44
Volume at STP :
= 0.44 x 22.4 L
= 9.856 L
