Answer: Hope This Helps

Explanation:

1: The nephrons contain a filter called the glomerulus. The fluid that is filtered from the blood then travels down through a tubule. The tubule adjusts the level of wastes that will leave the body in the urine.

(I dont know the second part so hope this half answer helps a little bit. Sorry.)

✍ 1. ➺ Nephrons have filters known as glomerulus (they are a cluster of very thin-walled blood capillaries). Glomerulus filters our blood & then removes any unwanted waste materials. Now, this filtrate which is removed out from the blood gets collected & filtered again in the Bowman's Capsule & tubules from where nephrons remove glucose, amino acids & a major amount of water. The urine forming in each kidney now enters a long tube (ureter) where urine passes & gets stored in the urinary bladder. Urine gets passed out of the body through the urethra.

The cell potential of a redox reaction occurring in an electrochemical cell under any set of temperature and concentration condi

avanturin [10]

Answer : The actual cell potential of the cell is 0.47 V

Explanation:

Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given redox reaction is :

$Ni^{2+}(aq)+Zn(s)\rightarrow Ni(s)+Zn^{2+}(aq)$

The balanced two-half reactions will be,

Oxidation half reaction : $Zn\rightarrow Zn^{2+}+2e^-$

Reduction half reaction : $Ni^{2+}+2e^-\rightarrow Ni$

The expression for reaction quotient will be :

$Q=\frac{[Zn^{2+}]}{[Ni^{2+}]}$

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

Now put all the given values in this expression, we get

$Q=\frac{(0.0141)}{(0.00104)}=13.6$

The value of the reaction quotient, Q, for the cell is, 13.6

Now we have to calculate the actual cell potential of the cell.

Using Nernst equation :

$E_{cell}=E^o_{cell}-\frac{RT}{nF}\ln Q$

where,

F = Faraday constant = 96500 C

R = gas constant = 8.314 J/mol.K

T = room temperature = 316 K

n = number of electrons in oxidation-reduction reaction = 2 mole

$E^o_{cell}$ = standard electrode potential of the cell = 0.51 V

$E_{cell}$ = actual cell potential of the cell = ?

Q = reaction quotient = 13.6

Now put all the given values in the above equation, we get:

$E_{cell}=0.51-\frac{(8.314)\times (316)}{2\times 96500}\ln (13.6)$

$E_{cell}=0.47V$

Therefore, the actual cell potential of the cell is 0.47 V

amm1812

Nuclear Fusion is when two atoms (usually Hydrogen and helium because they are very light and abundant) are smashed together to form heavier elements and in the process releases massive amounts of energy. Nuclear Fission on the other hand is when a heavier atom is split apart at the nucleus and releases large amounts of energy and free neutrons and photons. (in the form of gamma rays)

Explain how chemicals and chemical reactions are an important part of our lives.

Zielflug [23.3K]

Chemical reaction is the basis of life for living organisms; no organism can remain alive without the occurrence of chemical reactions.
Chemical reactions that occur in the living organisms are called biochemical reactions, these reactions are needed for the organism to grow, develop, survive and remain alive; when the chemical reactions stop the organism die.
For instance, to remain alive one has to eat. The food eaten can not be useful to the body if the digestive enzymes do not carry out chemical reactions on it and convert it to a form that can easily enter the blood where it is needed.
