Answer:
duplet-A set of two things or people
Octet-A group of 8 things or people
There are several differences between a physical and chemical change in matter or substances. A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
Answer:
DECREASE BY A FACTOR OF FOUR
Explanation:
Using pressure equation:
P 1 / T1 = P2 /T2 (at constant volume)
P1 = P
T1 =T
P2 = ?
T2 = 4 T
So therefore;
P2 = P1T1/ T2
P2 = P T/ 4 T
P2 = 1/4 P
The pressure is decreased by a factor of four, the new pressure is a quarter of the formal pressure of the gas.
Ozone depleting chemicals are most likely belong to <u>halogen </u>group on the periodic table.
<h3>Ozone depleting chemicals are most likely to belong to which group on the periodic table?</h3>
Ozone depleting chemicals are the halogen group on the periodic table. Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromo-fluorocarbons and methyl chloroform. Fluorine, chlorine, bromine, iodine, astatine and tennessine are the elements of halogen group elements. These elements greatly affected the ozone layer.
So we can conclude that Ozone depleting chemicals are most likely belong to halogen group on the periodic table.

The rcf (recipe conversion factor)= 0.6
<h3>What is the rcf (recipe conversion factor)?</h3>
- The conversion factor approach is the most typical technique for modifying recipes.
- Finding a conversion factor and multiplying the ingredients in the original recipe by that factor are the only two steps needed to do this.
- Remember that the conversion factor will be larger than 1 if you are raising your amounts to be sure you are finding it correctly.
- The factor will be less than 1 if your amounts are being decreased. Use the conversion factor approach if you come across a recipe that is written in a standard format.
- The production of phenolic monomers from lignin is effective and selective when done using reductive catalytic fractionation (RCF).
How this is calculated?
Conversion Factor = New Yield ÷ Old Yield
=80/134
=0.5970
=0.6(rounded to nearest tenth)
