Can someone explain the anatomy and physiology of the leopard eye and vision, or provide some journals describing

can someone please help me with these problems!

1.) What is the energy stored in a small battery if it can move 660 C through a potential difference of 1.10 V? ____KJ

2.) A 19-Ω resistor has a potential difference of 4 V across it. What current flows through the resistor? ____A

I am trying to balance this redox reaction, i balanced the half reactions but get stuck when i try to balance out the electron portion some please help!

Br03- + N2H4---> Br- + N2

I broke it up into half reactions and added H20 and H where needed.

6H+ + Br03- ---> Br- + 3H20 ( stuck on balancing charges and adding electrons here)

N2H4 ----> N2 + 4H+ + 4e-

Can someone please explain im am soo confused!!

Why the enzyme trypsin, chymotrypsin, and elastase are named serine proteases CAN SOMEONE PLEASE EXPLAIN!

I cannot seem to get the right anwser, I am unsure if i am plugging into the right spot.

1.) The activation energy of a reaction is 56.8 kJ/Mol and the frequency factor is 1.5x10^11/s. Calculate the rate constant of the reaction at 25 Celsius. PLEASE HELP!!!

How do Integrated rate laws allow the time dependence of reactant concentration to be used to determine the rate constant, reaction order, etc.?

Explain why, when we hold our breath, we are risking respiratory acidosis, and when we hyperventilate we risk respiratory alkalosis.

1.) What is True about bond energy?

a.) the individual atoms have more potential energy than the combined atoms

b.) Upon making the bond, energy is released by the reacting atoms to the surroundings

c.) bond energy is a fixed value for a given pair of reacting atoms

d.) all the above

2.) The change H of a reaction has the same value, with opposite ign, for both the forward and reverse reactions

a.) only when the system is in equilibrum

b.) because H is a state function

c.) Only under certain conditions

d.) because of the entropy factor

e.) all the above

3.) Entropy, S, is GREATER at?

a.) 55C than it is at 5C

b.) liquid than gaseous state

c.) high than low chemical concentration

d.) all of the above

I am really unsure how to set these problems up!!!

1.) The coefficient of linear expansion of brass is 1.9 x10^-5° C^−1. At 20.6° C, a hole in a sheet of brass has an area of 1.00 mm2. How much larger is the area of the hole at 31.0° C?

2.) A cylindrical brass container with a base of 60.0 cm2 and height of 20.0 cm is filled to the brim with water when the system is at 25.0° C. How much water overflows when the temperature of the water and the container is raised to 94.5° C? (The coefficient of volume expansion for water and brass are 2.07x10^-4 K^1 and 5.7x10^-5 K^−1, respectively.)
