The one in the cupbard looses its CO2 first as its warmer so its solution has a lower solibility to the CO2 gas 

at lower temperatures the CO2 has less energy to escape from the solution of soda as CO2 in a solution is unstable it wants to be released 

hope that helps <span />

a 3.81 g sample of NaHCO3 was completely decomposed. After decomposition, Na2CO3 had mass of 2.86g. Determine mass of H2CO3 prod
qaws [65]

Answer:

1.67g H2CO3 are produced

Explanation:

Based on the reaction:

2NaHCO3 → Na2CO3 + H2CO3

<em>2 moles of NaHCO3 produce 1 mole of Na2CO3 and 1 mole of H2CO3</em>

To solve this question we need to find the moles of Na2CO3 = Moles of H2CO3. With their moles we can find the mass of H2CO3 as follows:

<em>Moles Na2CO3 -Molar mass: 105.99g/mol-</em>

2.86g Na2CO3 * (1mol/105.99g) = 0.02698 moles Na2CO3 = Moles H2CO3

<em>Mass H2CO3 -Molar mass: 62.03g/mol-</em>

0.02698 moles  * (62.03g/mol) =

<h3>1.67g H2CO3 are produced</h3>

Which statement illustrates the difference between a chemical reaction and a nuclear reaction?A nuclear reaction releases more e
denpristay [2]

According to the research, a nuclear reaction releases less energy per gram and appears to violate the law of conservation of mass.

<h3>What is a nuclear reaction?</h3>

It is a procedure that leads to combining and modifying the nuclei of atoms and subatomic particles and appears to violate the law of conservation of mass.

Through this kind of process, the nuclei can be combined or fragmented, absorbing or releasing particles and energy according to each case.

Therefore, we can conclude that according to the research, a nuclear reaction releases less energy per gram and appears to violate the law of conservation of mass.

ludmilkaskok [199]

Answer:

Subscript, or B

Explanation:

<em>AgS is the equation for the chemic reaction of Silver + Sulfur, since the subscript of 2 goes by the g in the equation, this would equal subscript.</em>

<em />

<em>Remember subscripts are located at the BOTTOM of a coefficient and superscripts are located at the TOP of a coefficient.</em>
