As the atmospheric pressure decreases, the temperature at which water will boil

1 answer:

4 0

As the atmospheric pressure decreases, the temperature at which water boils decreases too. An increase in pressure leads to an increase in boiling point while a decrease in pressure leads to a decrease in boiling point.

A high speed train travels 176 miles in 7 hours. What is the speed of the train

umka21 [38]

Answer:

25 mph

Explanation:

So we have to find the unit rate, or you could use the DTS triangle, but both say you have to divide, so our equation is:

176 ÷ 7 = 25.14

But I'm going to round that

So the train is traveling at 25 mph

hope this helps:/

which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?

NeTakaya

The given question is incomplete. The complete question is as follows.

Which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?

(a) at higher temperatures, high-energy collisions happen less frequently.

(b) at low temperatures, low-energy collisions happen more frequently.

(c) at higher temperatures, less-energy collisions happen less frequently.

(d) at higher temperatures, high-energy collisions happen more frequently

Explanation:

When we increase the temperature of a chemical reaction then molecules of the reactant species tend to gain kinetic energy. As a result, they come into motion which leads to more number of collisions within the molecules.

Therefore, chemical reaction will take less amount of time in order to reach its end point. This means that there will occur an increase in rate of reaction.

Thus, we can conclude that the statement at higher temperatures, high-energy collisions happen more frequently, best explains why an increase in temperature increases the rate of a chemical reaction.

What is the molecular geometry around each carbon atom in a saturated hydrocarbon?

Lelu [443]

Answer:
<span>Molecular geometry around each carbon atom in a saturated hydrocarbon is Tetrahedral.

Explanation:
</span> In saturated hydrocarbons (-CH₂-) the central atom (carbon) is bonded to either three or two hydrogen atoms and one or two carbon atoms. So, the central atom is having four electron pairs and all pairs are bonding pairs and lacks any lone pair of electron. According to Valence Shell Electron Pair Repulsion (VSEPR) Theory the central atom with four bonding pair electrons and zero lone pair electrons will attain a tetrahedral geometry with bond angles of 109°.
