Oxygen is 16 times more massive.
Hydrogens atomic mass = 1.001 g/mol
Oxygen atomic mass = 15.999 g/mol

An oxygen atom is 16x more massive than a hydrogen atom.

You can figure this out by comparing the atomic masses of the two elements: oxygen has an atomic mass number of 16, and hydrogen has an atomic mass number of 1. Thus, an oxygen atom is 16 times more massive than a hydrogen atom.

How many carbon dioxide molecules must be added to rubp to make a single molecule of glucose?
Pani-rosa [81]

Answer:

6 carbon dioxide molecules

Explanation:

The Calvin cycle generates the necessary reactions for the fixation of carbon in a solid structure for the formation of glucose and, in turn, regenerates the molecules for the continuation of the cycle.

The Calvin cycle is also known as the dark phase of photosynthesis or also called the carbon fixation phase. It is known as the dark phase because it is not light dependent as is the first phase or light phase .

This second stage of photosynthesis fixes the carbon of the absorbed carbon dioxide and generates the precise number of biochemical elements and processes necessary to produce sugar and recycle the remaining material for continuous production.

The Calvin cycle uses the energy produced in the light phase of photosynthesis to fix the carbon dioxide (CO2) carbon in a solid structure such as glucose, in order to generate energy.

The glucose molecule composed of a six-carbon main structure will be further processed in glycolysis for the preparatory phase of the Krebs cycle, both part of the cellular respiration.

The Calvin cycle produces in six turns a six-carbon glucose molecule and regenerates three RuBP that will be catalyzed again by the RuBisCo enzyme with CO2 molecules for the restart of the Calvin cycle.

The Calvin cycle requires six molecules of CO2, 18 ATP and 12 NADPH produced in the light phase of photosynthesis to produce a glucose molecule and regenerate three RuBP molecules.

Phosgene is a highly toxic gas made up of carbon, oxygen, and chlorine atoms. Its density at 1.05 atm and 258C is 4.24 g/L. (a)
VikaD [51]

Answer:

Molar mass = 99 g/mol

Explanation:

Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2

The molar mass is given as the sum off the individual atomic mass of the elements in the compound.

Molar mass = C + O + 2Cl

Molar mass = 12 + 16 + 2(35.5)

Molar mass = 99 g/mol

Which concept can explain the acidic character of Carbon dioxide?​
Mamont248 [21]

Answer:

The concept of lewis acids and bases can explain the acidic nature of CO2. A lewis acid is a compound which can accept an electron pair whereas a lewis base is a compound which can donate an electron pair. CO2 acts as a lewis acid.
