the element in each balloon?

Answer:

Oxygen

Explanation:

If two balloons are filled with hydrogen gas and helium gas respectively, then we want to identify what gas is in each balloon, we have to do so by exposing the both balloons to flame in an oxygen atmosphere.

Hydrogen combines with oxygen in the presence of a flame with quite a loud sound and the flame is sustained but when a flame is brought near helium gas in a balloon, the gas will only make a little sound when exposed to the flame and extinguish the flame.

The reason for the explosion of the gas in the hydrogen balloon is that combustion of hydrogen gas is exothermic. The heating up of surrounding air molecules leads to a sudden explosion.

However, the helium balloon makes a little sound when the balloon is ruptured releasing helium gas which extinguishes the flame.

This is going to take a while..

1. 2AgI + Na2S --> Ag2S + 2NaI

2. Na3PO4 + 3HCl --> 3NaCl + N3PO4

3. Ba3N2 + 6H2O --> 3Ba(OH)2 + 2NH3

4. TiCl4 + 2H2O --> TiO2 + 4HCl

5. 3CaCl2 + 2Na3PO4 --> Ca3(PO4)2 + 6NaCl

6. 2NaBr + Cl2 --> 2NaCl + Br2

7. Mg(OH)2 + 2HCl --> MgCl2 + 2H2O

Hopefully that helps.

When an oxidant is present, vitamin C can be converted to a product described as (5R)-5-[(1S)-1,2-dihydroxyethyl]-3,4-dihydroxy-
Step2247 [10]

Answer:

D) Vitamin C is oxidized to yield a furan ring with 3 carbonyl groups and no double bonds

Explanation:

We can tell that the compound " (5R)-5-[(1S)-1,2-dihydroxyethyl]-3,4-dihydroxy-furan-2,3,4(5H)-trione " has 3 carbonyl groups due to it having "trione" in the name (and it lacking other carbonyl group names, like amide or carboxylic acid).

As there is no "-ene" part of the name referencing a double bond, the only option left is option D).
