Answer:
Water is polar covalent while isoporopanol is covalent
Explanation:
Water contains polar covalent bonds. Water has a high dipole moment and thus dissolves ionic substances easily such as sodium chloride. Water is also a good electrolyte. Water is not volatile. Water molecules are held together by hydrogen bonds. Isopropanol is a covalent compound. It is non polar and suitable for dissolving non polar substances such as campohor. It is volatile but dissolves in water due the the -OH group present in the molecule.
Answer : The concentration of are 0.127 ppm, 0.127 ppm and 0.254 ppm respectively.
Explanation : Given,
Mass of =
Volume of solution = 2.25 L
First we have to calculate the concentration in terms of g/L.
conversion used :
As we know that,
1 mg/L = 1 ppm
0.127 mg/L = 0.127 ppm
So, the concentration will be 0.127 ppm.
The concentration of in ppm is, 0.127 ppm.
Now we have to calculate the concentration of and .
We assume that, dissociates 100 % in the solution then the balanced reaction will be:
From the reaction we conclude that the mole ratio of is, 1 : 1 : 2. So,
The concentration of = 0.127 ppm
The concentration of = 2 × 0.127 ppm = 0.254 ppm
Answer:
The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN3 to decompose. The nitrogen gas that is generated then fills the airbag. hope that helps love!
