Answer:

1) Condensation.

2) See below.

Explanation:

1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.

2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.

For each mole of glucose (C6H12O6) completely oxidized by cellular respiration, how many moles of CO2 are released in the citric
topjm [15]

Answer:

4  

Step-by-step explanation:

The reactions are:

Glycolysis:                      1 glucose ⟶ 2 pyruvate

Link reaction:         2 × [1 pyruvate ⟶ 1 acetyl CoA]

Citric acid cycle: 2 × [1 AcetylCoA ⟶ 2 CO₂]

Now, add the reactions, cancelling species that occur on both sides of the reaction arrow,

             1 glucose ⟶ <u>2 pyruvate </u>

           <u>2 pyruvate</u> ⟶ <u>2 acetyl CoA </u>

        <u>2 AcetylCoA </u>⟶ 4 CO₂

<em>Overall</em> : 1 glucose ⟶ 4 CO₂

For each mole of glucose, four molecules of CO₂ are released in the citric acid cycle.

Neon atoms are known to produce a mass spectrum that consists of three peaks at m/z values of 20, 21 and 22, with the relative a
wel

Answer:

Explanation:

m / z = 20 , 21 , 22

m / 1 = 20 , 21 , 22

m = 20 , 21 , 22 .

ratio of isotopes = 112 : 0.21 : 11.1

Average atomic mass = (112 x 20 + .21 x 21 + 11.1 x 22) / (112 + .21 + 11.1 )

=  (2240 + 4.41 + 244.2) / 123.31

= 2488.61 / 123.31

= 20.18
