The balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.
<h3>What are balanced chemical equations?</h3>
Balanced chemical equations are equations in wgich the moles of each species on both sides of the reaction are equal.
To balance chemical equations, numerical coefficients are placed in front of the species in the reaction.
The balanced equations of the reaction are as follows:
Therefore, the balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

If 0.380 mol of barium nitrate is allowed to react with an excess of phosphoric acid, 0.127 moles of barium phosphate could be formed.
<h3>How to calculate number of moles?</h3>
The number of moles of a compound can be calculated stoichiometrically as follows:
Based on this question, the following chemical equation is given:
Ba (NO3)2+ H3PO4 → Ba3(PO4)2+ HNO3
The balanced equation is as follows:
3Ba(NO3)2 + 2H3PO4 → Ba3(PO4)2 + 6HNO3
3 moles of barium nitrate produces 1 mole of barium phosphate
Therefore, 0.380 moles of barium nitrate will produce 0.380/3 = 0.127moles of barium phosphate.

Answer:
- Only the methyl ester of aspartame is sweet. True
- Amide bonds can be hydrolyzed under only acidic conditions. False
- The zwitterionic form of the amide bond is the most favored resonance form. True
- The phosphoric acid in soda hydrolyses the aspartame ester making it sweet. False
Explanation:
-
Aspartame is obtained by combining phenylalanine and aspartic acid. Its main impurity is dicetopiperazine, which does not possess sweetening properties.
- Amide bonds can be hydrolyzed both under basic and acidic conditions.
- The zwitterionic form of the amide bond is the most favored resonance form. A zwitterion is an electrically neutral chemical compound, but it has formal positive and negative charges on different atoms, presenting high stability
- Phosphoric acid creates an acidic medium that improves the absorption of carbon dioxide, reducing the pressure generated by carbon dioxide and thus allowing bottleneck. Phosphoric acid has a bitter taste that is offset by the addition of sugar

Answer:
The mole and atonmicity of both the gases are different, the number of atoms is not same.
Explanation:
The number of atoms in a molecule (compound) depends on mole number and atomicity.
↬ Mole of 100 g H₂ = 100g ÷ 2u = 50 mole
∴Number of atoms in 100 g H₂
= 2 x 50 x 6.022 × 10²³
= 6.022 x 10²⁴ atoms
↬ Mole of 100 g He = 100g ÷ 4u = 25 mole
∴ Number of atoms in 100 g He
= 1 × 25 × 6.022 × 10²³
= 150.55 × 10²³
= 1.5055 x 10²⁵ atoms
Thus, The mole and atonmicity of both the gases are different, the number of atoms is not same.

Answer:9.18 m/s
Explanation:
The average speed for the entire trip is found ......total distance/total time. Remember r*t=d, so divide both sides by t and get r = d/t.
So the cyclist went 800+500+1200 m = 2500 m for total distance.
10t =800 leads to t=80 sec
5t=500 leads to t=100 sec
13t = 1200 leads to t = 92.3 sec
total time is 272.3 sec
Average speed for the entire trip is 2500 / 272.3 = 9.18 m/s
