The effusion rate is 1.125 cm/sec for ammonia.
How to find effusion rate ?
Effusion rate (r1) HCl = 43.2 cm/min
Molar mass (m2) NH3 =17.04g/mole
Molar mass (m1) HCl =36.46g/mole
- Substitute the molar masses of the gases into Graham's law and solve for the ratio.
firstly convert 43.2 cm/min into cm/sec i.e., 0.72 cm/sec
Then,
0.72/r2 =√17.04/36.46
r2= 1.125 cm/sec
Hence, the rate of diffusion of ammonia is 1.125 times faster than the rate of diffusion of hydrogen chloride.

Answer:
The explanation is given below
Explanation:
Toxicity is a measure of how harmful a substance is on a living organism (causing illness, injury or even death). There are several factors that must be considered when evaluating toxicity:
- Dose of exposure: the amount of substance to which the organism has been exposed to;
- Frequency of exposure: how many times (and for how long) the individual has been exposed to the substance;
- Age and health condition of the individual exposed;
- Genetic makeup: the genetic backgroun of an organism will determine its response and degree of sensitivity to a given substance.
Moreover, there are five main characteristics of substances that determine its toxicity: Solubility (hidrophilic or lipophilic substances), persistence (for how long the substance remains the same and cause the same damage), bioaccumulation (when the substance is progresivelly incorporated in tissues), biomagnification (when the amount of substance rise along trophic levels) and other chemical interactions (different interactions with other chemicals can increase the degree of damage) .

Answer:
Yes
Explanation:
For example, let's take the case of Carbon Tetrachloride (CCl4). The individual carbon-chlorine bond is polar, however, the dipole moments of each bond cancel each other out to leave a nonpolar molecule.
