Answer:
I interpret the answers as being nonmetallic and metallic.
Explanation:
Nonmetals are in groups 14 - 18. Electronegativity is referred to as the want to attract electrons to an atom. Noble gases (group 18) have eight valence electrons in their outer subshells and are therefore atomically stable. Elements with only 7 valence electrons are very electronegative because they desire to obtain an electron to reach stability more than a group 2 element would (they are more likely to drop electrons by giving away in order to reach atomic stability of a group 18 element). This coincides with electron configuration, which is a very lengthy topic to cover. You can conduct more research if you would need it.
Answer:
Final volume = V₂ = 8.2L
Explanation:
Given data:
Initial volume = 12.3 L
Initial pressure = 40.0 mmHg
Final volume = ?
Final pressure = 60.0 mmHg
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
40.0 mmHg × 12.3 L = 60.0 mmHg × V₂
V₂ = 40.0 mmHg × 12.3 L / 60.0 mmHg
V₂ = 492 mmHg. L / 60.0 mmHg
V₂ = 8.2L

Answer:
chymotrypsin, cleaves peptide bonds selectively on the carboxylterminal side of the large hydrophobic amino acids such as tryptophan, tyrosine, phenylalanine, and methionine
Under certain conditions butane reacts with oxygen to form butanone which can be easily hydrogenated to butanol. Butene is easily made from butanol by elimination of water.
Explanation:
These are for the first too
The molarity of the base ( ammonium hydroxide) is calculated as follows
find the moles of Nitric acid =molarity x volume
=29.5 x 0.175 =5.163 moles of nitric acid
write the equation for reaction
HNO3+ NH4OH =NH4NO3 +H2O
by use of mole ratio between HNO3 to NH4NO3 which is 1:1 the moles of NH4OH is also 5.163 moles
molarity =moles/volume
= 5.163 /50=0.103 M is the molarity of the base
