a. 661.23 m/s
b. the rate of effusion of Ammonia = 4.5 faster than Silicon tetra bromide

Given
T = 25 + 273 = 298 K
Required
a. the gas speed
b. The rate of effusion comparison
Solution
a.
Average velocities of gases can be expressed as root-mean-square averages. (V rms)
R = gas constant, T = temperature, Mm = molar mass of the gas particles
From the question
R = 8,314 J / mol K
T = temperature
Mm = molar mass, kg / mol
Molar mass of Ammonia = 17 g/mol = 0.017 kg/mol
b. the effusion rates of two gases = the square root of the inverse of their molar masses:
M₁ = molar mass Ammonia NH₃= 17
M₂ = molar mass Silicon tetra bromide SiBr₄= 348
the rate of effusion of Ammonia = 4.5 faster than Silicon tetra bromide
Answer: Environment
Explanation:
Organisms can be placed in an environment not like their own, but can learn to adapt by exploring and interacting with the new environment.
Answer:
B: it allow quick conversation to others
Agents that antagonize the effects of acetylcholine are called anticholinergic.
<span>Anticholinergic blocks this neurotransmitter acetylcholine within the nervous system, by deactivating nerve impulses as a result of the binding of this neurotransmitter so that it cannot reach its receptor in nerve cells.</span>
Answer:
The answer to your question is organic or non polar compound.
Explanation:
Acetone is an organic compound then it's organic and one characteristic of these compounds is that they are non polar.
Water, aqueous hydrochloric acid and aqueous sodium chloride are inorganic and they are polar, they dissolve compounds similar to them, inorganic and polar compounds.
