That looks like an Acacia tree on the savanna’s of Africa. Perennial plants live for many years. I think this tree survives for many years. Read about that type of tree to see if you come to that conclusion.

Which of these statements is not true about chemical reaction rates?
Sliva [168]
I think it is A. The reaction rates can change.
I think we all know that B. and C. are incorrect, but I took a science lesson about this and it specifically said that on a graph of a rate, a curved line is NOT constant, meaning it is possible to not be constant.

Help please. 15.0 moles of gas are in a 3.00L tank at 23.4∘C . Calculate the difference in pressure between methane and an ideal
CaHeK987 [17]
Using PV=nRT or the ideal gas equation, we substitute n= 15.0 moles of gas, V= 3.00L, R equal to 0.0821 L atm/ mol K and T= 296.55 K and get P equal to 121.73 atm. The Van der waals equation is (P + n^2a/V^2)*(V-nb) = nRT.  Substituting  a=2.300L2⋅atm/mol2 and b=0.0430 L/mol, P is equal to 97.57 atm. The difference is <span>121.73 atm- 97.57 atm equal to 24.16 atm.</span>
