Uh well Hydronium is H30+ soooo if Water is Neutral, then H30+ is an Acid, cause of the +? idk lol

a compound that produces hydrogen ions when dissolved in water. Chemical Formula usually HX(X = monatomic or polyatomic ion). Chemical formula = H+

This means its acid :D

Hope I help :3

Baking soda mixed with vinegar produces carbon dioxide and water. The best way to prove that no mass was lost during this reacti

lord [1]

Given what we know, we can confirm that the best way to prove that no mass was lost during the reaction would be to follow option C and determine the masses of all substances before and after the reaction.

<h3>Why is this the best method?</h3>

This method provides two sets of data in order to draw a comparison. The other option will either not produce comparable data, or do not take into account all of the elements being produced.

Therefore, by comparing the mass of baking soda and vinegar before the reaction to the mass of carbon dioxide and water after the reaction, we can analyze the differences if any, and confirm that no mass was lost during the reaction.

Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it

Answer: The equilibrium concentration of $COF_2$ is 0.332 M

Explanation:

We are given:

Initial concentration of $COF_2$ = 2.00 M

The given chemical equation follows:

$2COF_2(g)\rightleftharpoons CO_2(g)+CF_4(g)$

Initial: 2.00

At eqllm: 2.00-2x x x

The expression of $K_c$ for above equation follows:

$K_c=\frac{[CO_2][CF_4]}{[COF_2]^2}$

We are given:

$K_c=6.30$

Putting values in above expression, we get:

$6.30=\frac{x\times x}{(2.00-2x)^2}\\\\x=0.834,1.25$

Neglecting the value of x = 1.25 because equilibrium concentration of the reactant will becomes negative, which is not possible

So, equilibrium concentration of $COF_2=(2.00-2x)=[2.00-(2\times 0.834)]=0.332M$

Hence, the equilibrium concentration of $COF_2$ is 0.332 M

Bella observes that the gas-filled tire of her bicycle becomes a little deflated when she keeps the bicycle outside in cold weat

weqwewe [10]

The low temperature outside lowers the volume of the gas according to Charles' law because this law describes how a gas will behave at constant pressure. It shows that the volume of a given mass of a gas is directly proportional to the absolute temperature provided the pressure remains constant. An increase in temperature leads to an increase in volume while a decrease reduces the volume. This is due to the reduction in the distances traveled by the vibrating particles of the gas because of the lost kinetic energy.
