Answer:

C. Reducing the air pressure allows the molecules to escape.

Explanation:

Lower air pressure can be found in the mountain or any high ground place. In this place, you will need less temperature to boil water or other liquid.

A liquid phase will change into gas when it reaches the vapor pressure of the surrounding air. At that point, the molecule can move freely as the gas phase. Since the atmospheric pressure is preventing the liquid to become gas, if the pressure is lower, the liquid can boil at a lower temperatures.

Which equilibrium system has HCO3- acting as a Brønsted-Lowry base?

IrinaVladis [17]

A Brønsted-Lowry base is a base is a proton acceptor.

In the only case where this is done is when HCO3- accepts a proton and becomes H2CO3.

In the other cases, HCO3- is donating a proton which makes it an acid.

Does water added to a flask containing chlorine gas and solid sodium react in the chemical reaction to make sodium chloride

Jet001 [13]

Answer:

Explanation:

Chemically, we can have a reaction between chlorine gas and solid sodium

This reaction is actually explosive and would produce fine powder of sodium chloride

We have the reaction as follows:

$2Na_{(s)}+Cl_{2(g)}\rightarrow2NaCl_{(s)}$

Essentally, what we can deduce from here is that we do not need to add water to the flask. Except for the reason that we would want the sodium chloride solid in the solution form, there is absolutely no reason to add water to the flask as the reaction would proceed normally

If a person looking at a poster sees green instead of yellow and doesn't see red at all, this person most likely has color blind

Inga [223]

<span>People with protanopia are unable to sense any ‘red’ light, people with deuteranopia do not sense ‘green’ light and people with tritanopia cannot sense ‘blue’ light. If a person perceives the color green, then the yellow sensitive nerves must work somewhat effectively since green is a combination of yellow and blue. Red-sensitive nerves are most likely not responding properly for this person. The answer is C.</span>

A 3.82L balloon filled with gas is warmed from 204.9K to 304.8 K.

likoan [24]

Given :

A 3.82L balloon filled with gas is warmed from 204.9K to 304.8 K.

To Find :

The volume of the gas after it is heated.

Solution :

Since, their is no information about pressure in the question statement let us assume that pressure is constant.

Now, we know by ideal gas equation at constant pressure :
