The answer would be D. because when an acid and base mix the start to cancel each other out causing it to neutralize
Answer:
3.27 minutes
Explanation:
To solve this problem we will first convert miles/hour to km/min. For this purpose we will require following reference conversions as;
1 Mile = 1.60934 Km
And,
1 Hour = 60 min
Therefore,
As,
1 Mile = 1.60934 Km
Then,
74 Miles = X Km
Solving for X,
X = 74 miles × 1.60934 Km ÷ 1 mile
X = 119.10 Km
Therefore,
119.10 Km were travelled in = 60 min
So,
6.50 Km will be travelled in = X min
Solving for X,
X = 60 min × 6.50 Km ÷ 119.10 Km
X = 3.27 minutes
This is where something called Graham's Law applies. Grahams law says that the rate of effusion is inversely proportional to the square root of the molar mass of a gas. What that means is that the less the molar mass of a gas is, the less quickly the gas effuses (effusion being the rate at which a gas can travel through a small hole). A great way to think about this is that effusion is thought about as though the gas is traveling through a small hole, so smaller particles would be able to go through it with greater ease than would a large particle. I don't know what particular sentences the question asks for are, but the answer should be that gas A (molar mass 4) has the greatest effusion rate, gas B (molar mass 16) has the second fastest effusion rate, and gas C (molar mass 32) has the slowest effusion rate.
Acid rain is formed by chemicals let off into the atmosphere further introducing the nitrogen oxides which are attached to the water vapour and than mixed together further making acid rain which contains a pH scale of 6 a pale light acid though very much effective.
