Answer:
Option A.
Lower air pressure results in a lower boiling point
Explanation:
This is because in an open system, the lower the pressure the lesser the energy that will be required for boiling point. The is little or no collision of air molecules with the surface of the liquid
But if there is increase in pressure, more energy will be required to get to boiling point because there will be strong collision between air molecules and surface of the liquid.
Answer:
A solution labeled "0.105 M NaOH" would contain 0.105 moles of NaOH in each liter of solution.
Explanation:
The concentration of a solution in Molarity (M) stands for the number of moles of that substance contained in 1 L of solution.
Molarity = Concentration in mol/L = (Number of moles of solute) ÷ (Volume of solution in L)
Molarity = Concentration in mol/L = 0.105 M = 0.105 mol/L
Number of moles of solute = ?
Volume of solution in L = 1 L
0.105 = Number of moles of solute × 1
Number of moles of solute = 0.105 mole
Hence, a solution labeled "0.105 M NaOH" would contain 0.105 moles of NaOH in each liter of solution.
Hope this Helps!!!
Genetic: an organism uses energy for cellular respiration, and has all the genes necessary to make the proteins to accomplish it.
The compound that ontains the most deactivated aromatic ring is the one called Nitrogen dioxide also knwon as NO2. Let me explain a little bit more about the aromatic rings. These rings are simple aromatics, or arenes, that consist of a conjugated planar ring system. Nitrogen generally is a simple aromatic ring that can be heterocyclic because containsnon-carbon ring atoms. The rings of the nitrogen can be separated into basic aromatic rings and that is why this ompound is also refered as a deactivated aromatic ring.
