Vadim26 [7]2 years ago

Hey there!

We can tell from the information we are given that the sum of protons and neutrons is 13, there is 6 protons since it is a carbon atom, and there is no charge which means the number of protons is equal to the number of electrons.

6 + n = 13

n = 7

The number of protons is equal to the number of electrons, so there is 6 electrons.

The isotope 13C has 6 protons, 6 electrons, and 7 neutrons.

Hope this helps!

The process where bacteria takes nitrogen out of the air and makes it usable for other organisms is called
Likurg_2 [28]

Answer:

The process is called Nitrogen fixation

Explanation:

The nitrogen fixation is a process carried out by some prokaryotic microorganisms (bacteria), specifically those have the presence of the nitrogenase enzyme. The bacteria absorb the atmospheric nitrogen (N2) from the roots of plants, and the nitrogenase enzyme, with the help of two proteins that act as electron donors and acceptors (nitrogenase complex) reduce the nitrogen to ammonia (NH3), then the ammonia is ionized to NH4+ (ammonium). Followed by that, the ammonia is oxidated to nitrates and nitrites, which are finally absorbed again by plants.

A sample of gas exerts a pressure of 16 atm at a temperature of 340 K. What is the pressure of the gas in atm if the temperature
gavmur [86]

Answer:

P2 = 19.2atm

Explanation:

Initial pressure (P1) = 16atm

Initial temperature (T1) = 340K

Final temperature (T2) = 408K

Final pressure (P2) = ?

This question involves the use of pressure law

Pressure law states that the pressure of a fixed mass of gas is directly proportional to it's temperature provided that volume is kept constant.

Mathematically,

P = kT, k = P / T

Therefore,

P1 / T1 = P2 / T2 = P3 / T3 = ......=Pn / Tn

P1 / T1 = P2 / T2

We need to solve for P2

P2 = (P1 × T2) / T1

Now we can plug in the values and solve for P2

P2 = (16 × 408) / 340

P2 = 6528 / 340

P2 = 19.2atm

The final pressure (P2) of the gas is 19.2atm

How many liters of water can be formed if 1.65 liters of ethylene are consumed
alexandr1967 [171]
Ethylene Burns in the presence of O₂ to produce CO₂ and H₂O vapors;

                               C₂H₄  +  3 O₂   →   2 CO₂  +  2 H₂O

According to equation, 

22.4 L (1 mole) C₂H₄ reacts completely to produce  =  44.8 L (2 moles) of H₂O

So, 

1.65 L of C₂H₄ on complete reaction will produce  =  X L of H₂O

Solving for X,

                                  X  =  (1.65 L × 44.8 L) ÷ 22.4 L

                                  X  =  3.3 L of H₂O

Where did the mass of the forest tress come from? What happen to that mass when the forest burns?
mart [117]

Answer:

The mass of the forest comes from carbon and carbon is retrieved from carbon-dioxide that trees used during the process of photosynthesis. In the process of photosynthesis, carbon-dioxide is utilised from the atmosphere by trees and release oxygen and ATP.

When the forest burns the mass again releases to atmosphere in the form of carbon which causes air pollution and increases carbon content in the atmosphere.
