Mars to see if those environments can support life. Living organisms have needs in order to survive. One of those needs is the r

ight temperature range. Yeast, a type of living organism, will be used to represent life. When yeast is in a suitable environment, it grows and produces carbon dioxide (CO2). The CO2 production by the yeast will be measured by a balloon, which will be attached to a water bottle filled with different mixtures. As the colony size of the yeast increases, so does the rate of CO2 production, as long as there is an ample supply of nutrients. If the environment inside the bottle is conducive to yeast growth, the maximum rate of CO2 production will be high. If the environment is hostile to yeast, the maximum rate of CO2 production will be low. If carbon dioxide production is low, then that environment cannot sustain yeast, and therefore cannot sustain life.

Balance the following reaction. A coefficient of "1" is understood. Choose option "blank" for the correct answer if the
Vera_Pavlovna [14]

2NH₂ + O₂ → N₂ + 2H₂O

<u>Explanation:</u>

Balancing the equation means, the number of atoms on both sides of the equation must be the same.

In the case of the given equation, we have to find out whether it is balanced or not.

2NH₂ + O₂ →  N₂ + 2H₂O

Atoms       Number of atoms before balancing     after balancing

                 LHS                 RHS                                    LHS         RHS

N               1                        2                                            2              2

H               2                       2                                            4              4                        

O               2                       1                                            2                2

To balance the N atoms, we have to put 2 in front of NH₂, and then to balance the H, O atoms, we have to put 2 in front of H₂O, so that each atom in left hand as well as right hand side of the equation was balanced.

What is the mass of 7.675 x 1023 atoms C? Answer in units of g.
nalin [4]

Answer: 15.3 grams C

Explanation:  1 mole is 6.02x10^23 atoms.  We can find the moles of C in 7.675 x 10^23 atoms of C by dividing:

(7.675 x 10^23 atoms C)/(6.02x10^23 atoms C/mole) = 1.275 moles C

The molar mass of carbon is 12g/mole.  So the mass of 7.675 x 10^23 atoms is (1.275 moles C)*(12 g/mole C) = 15.3 grams.
