How in the world will you solve for x in the equation 2^x=5?

ok so there are following three steps
A+F ---> AF Activation energy: +2 KJ/mol Heat of Rx= -.1 KJ/mol
AF+H -> AFM+ TM Activation E: +10KJ/mol Heat of Rx= +5.2 "
AFM+ F->AF+ TM Activation E: +15 " Heat of Rx= -6 "
I have to find which one is the rate-determining step : one thats slowest. This stuff is from the beginning of equlibrium. And for potential energy diagram which step should I use?

To measure the static friction coefficient between a 1.9 kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 470 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.053 m, what is the coefficient of static friction?

When the rubber band in a slingshot is stretched, it obeys Hooke's law. Suppose that the "spring constant" for the rubber band is k = 54 N/m. When the rubber band is pulled back with a force of 7.9 N, how far does it stretch? (answer in meters)

I just read about a planned missin that will be sending Seven Astronauts and a monkey to the sun. My question is this. Will the mission be safer if they go at night when it's dark and not as hot?

I need to find these items but I dont know what they are! Thanks.

1) a monocot leaf
2) a slice of break with black bread mold (is that just the normal mold that grows on old bread or a special kind?)
3) an example of an angiosperm organ that anchors, absorbs water and minerals, and stores food for the plant.
4) an organism from phylum tracheophyta, subphylum pteropsida.
5) a food made with the assistance of lactobacillus.
6) seeds from class angiospermae subclass monocotyledonae.
7) a swollen and maturated ovary sample of an organism from class angiophyta subclass dicotyledonae.

I have been searching forever and can not find any of these ones. Some help please?

The hierchy of arithmatic operators, addition, subtraction, multiplication, division and brackets when trying to solve simplification like (3+7)-76*122/77. The memory aid is BODMAS. I want to know the full form of BODMAS.
