In order to show other chemists the voltage generated by the reaction, the student would most likely record information in the Standard Reduction Potentials in Aqueous Solution at 25 degrees Celsius. This is a list of ions in the solution at standard temperature and pressure.
No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise
Hope this helped

Answer:
The urinary system's function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
Explanation:
B:Mintu should have decreased the time he touches the two metals
C:Mintu should have chosen a material with a lower specific heat
D:Mintu should have chosen a material the same temperature as the iron.
Answer: Option (C) is the correct answer.
Explanation:
The amount of heat necessary to raise the temperature of 1 gram of a substance by is known as specific heat of a substance.
Mathematically, q =
where, q = Heat energy
C = specific heat
= change in temperature
Hence, smaller is the amount of heat required by a substance to raise the temperature of its 1 g by more readily it will get hot.
Therefore, out of the given options specific heat of copper is small. So, copper will heat up quickly.
Thus, we can conclude that Mintu's error is that Mintu should have chosen a material with a lower specific heat.
Answer:
C - Mintu should have chosen a material with a lower specific heat.

Question:
Which of the following statements correctly describe(s) the driving forces for diffusion of Na+ and K+ ions through their respective channels? Select all that apply.
A)The diffusion of Na+ ions into the cell is facilitated by the Na+ concentration gradient across the plasma membrane.
B)The diffusion of Na+ ions into the cell is impeded by the electrical gradient across the plasma membrane.
C)The diffusion of K+ ions out of the cell is impeded by the K+ concentration gradient across the plasma membrane.
D)The diffusion of K+ ions out of the cell is impeded by the electrical gradient across the plasma membrane. The electrochemical gradient is larger for Na+ than for K+.
Answer:
"The concentration gradient and the electro-chemical gradient" describes the driving forces for diffusion of Na+ and K+ ions through their respective channels
Explanation:
The Na ions diffusion inside the cell is facilitated by the concentration gradient of the Na ions which is present across the plasma membrane. Hence, the diffusion of the K ions which is present outside the cell and will be impeded due to the electrical gradient which is present near the plasma membrane. Thus, the electro-chemical gradient is greater as compared to the Na ion than that of the K ion.

Explanation:
1 mol of helium contains 6.022 × 10²³ atoms
The balloon contains .
69.253 helium particles are in the balloon.
Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution to the Schrodinger equation for the helium atom has not been found.
A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution.
Helium is the element which you can find on the upper right side of the periodic table with atomic number 2. It comes first amongst the family of the noble gases. Helium falls under inert gas since its outermost electron orbital is full with two electrons.
The answer is 69.253.
