The first part of two is heat, not temperature, once that is cleared up: starting from 3: temperature, concentration, collisions, catalytic converter, surface area
Answer:
900g
Explanation:
Given parameters:
Number of moles of Sc = 20moles
Unknown:
Mass of Sc = ?
Solution:
To find the mass of the scandium given, we use the expression below:
Mass = Number of moles x molar mass
Molar mass of Sc = 45g/mol
So;
Mass of Sc = 20 x 45 = 900g

<u>Individual lipid molecules are free to diffuse laterally in the surface of the bilayer</u> is a general feature of the lipid bilayer in all biological membranes
Explanation:
The inside of the bilipid layer of the cell membrane of cells is made of fatty acid chains and cholesterol which are nonpolar molecules. they are sandwiched between the polar (glycerol) ends of the chains because they are hydrophobic and cannot interact with the ‘watery’ extracellular fluids. Non-polar molecules like lipids can easily diffuse laterally, within this lipid layers of the membrane because non-polar molecules interact well with other nonpolar molecules.

<u>Explanation:</u>
Hydrocarbons are defined as organic compounds which are only made from carbon and hydrogen atoms.
There are mainly 3 types of hydrocarbons:
- Alkanes are the type of hydrocarbons where a single bond is present between the carbon atoms. The general formula for these is , where 'n' is the number of carbon atoms.
- Alkenes are the type of hydrocarbons where at least one double bond is present between the carbon atoms. The general formula for these is , where 'n' is the number of carbon atoms.
- Alkynes are the type of hydrocarbons where at least one triple bond is present between the carbon atoms. The general formula for these is [tex]C_nH_{2n-2}, where 'n' is the number of carbon atoms.
