The number of protons in an atom of krypton is 36.
<u>Explanation:</u>
The number written above the symbol of Kr in the periodic table represents the atomic number of the element . Then the number written in the below represents the mass number.
So the mass number of krypton is 84 and the atomic number of krypton is 36. As it is known that number of protons and electrons will be equal in a stable element. Thus, the krypton atom will be having 36 protons.
Answer:
50% ISOPROPANOL / H2O - 1
25% ISOPROPANOL / H2O - 2
Pure water - 4
ISOPROPANOL / H2O - 3
Explanation:
More Isopropanol concentration is least polar. When the isopropanol is mixed with water its polarity increases. Pure water is most polar. The polarity of a substance is dependent on its ability to bent and mold in the shape as required.
V(NaOH)*M(NaOH)=V(HCOOH)M(HCOOH)
35.43ml*0.1150m=20.00ml*M(HCOOH)
M(HCOOH)=0.2037m
The anode is the metal that is higher on the list because it is more easily oxidized.
Answer:
Charles' Law
Explanation:
Charles' law gives the relationship between the the volume of a fixed mass of a gas and the absolute temperature.
It states that, Provided the pressure of a fixed mass of a gas remains constant, the volume of a fixed mass of a gas is directly proportional to the absolute temperature.
V/T= constant
When one of the conditions either temperature of volume changes under the same pressure, then the relationship.
V1T2= V2T1 is true
