• ### Which plant would be more likely to survive a drought: and Why?

A. One in soil depleted of bacterial and fungal associates or

B. one in soil with numerous, diverse bacterial and fungal species.

WHY!

• ### Determine the amount of heat (in kJ) associated with the production of 1.38x10^4g of NO2 according the following equation:?

2 NO(g) + O2(g)--> 2NO2(g)

ΔH = −114.6 kJ/mol.

• ### A gas expands and does PV work on its surroundings equal to 345 J. At the same time, it absorbs 141 J of heat from the surroundings.?

Calculate the change in energy of the gas. Note: PV work means work done by a changing volume against constant pressure.

IT IS NOT -204X10^2. IT SAYS IT IS WRONG. I KEEP GETTING THE SAME ANSWER.

• ### The atomic masses of 10B and 11B are 10.012938 and 11.009305amu. The average atomic mass of Boron is 10.811amu. Calculate the natural?

abundances of these two isotopes.

• • ### What is the value of ni for an electron that emits a photon of wavelength 92.38nm when it returns to the gourd state in the H atom?

6. I got a weird answer of like 7.9249.

• ### If you allow one pound of carbon dioxide to sublime (change from CO2(s) to CO2(g) at room conditions roughly 1 atm and 25C?

What volume would it occupy?

• ### The three top components of natural gas are Methane (CH4), ethane(C2H6)and propane (C3H8). Given your results for molar mass , which do you?

think is the most prevalent of the three compounds?

Oxidation:

Reduction:

• ### Sodium peroxide (Na2O2)is used to remove carbon dioxide from(and add oxygen to) the air supply in spacecrafts. It works by reaching CO2?

in the air to produce sodium carbonate(Na2CO3) and O2.

2Na2O2(s)+2 CO2(g)--> 2 Na2CO3(s)+O2(g).

What volume in liters of CO2 can be consumed at STP by 735g Na2O2?

• ### Use molecular orbital theory to determine whether F2^2+ is paramagnetic or diamagnetic and calculate it's bond order?

I have F2^2+ as paramagnetic, but I dont know how to calculate the bond order. Can someone help me
