Answer:
Option 4) equal to
Explanation
When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant
The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by
For example, for the following reaction :
aA + bB ⇔ cC + dD
Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
Answer: It turns blue litmus red
Explanation:
I just got it right on edge
Conduction is the act of touching 2 solids where one transfers heat
Answer:
He.
Explanation:
- Graham's law states that the effusion rate is inversely proportional to the molecular weight. It means that the gas with the lowest molecular weight will have the highest effusion rate.
The molecular weights of the given gases are:
Cl₂ = 70.9 g/mol.
He = 2.0 g/mol.
O₂ = 32.0 g/mol.
Ne = 20.17 g/mol.
<em>Since He has the smallest molecular mass, so it will have the highest rate of effusion.</em>
