Consider the Van der Vaals equation of state: (????+????????????)(????−????)=???????????? where p is pressure, V is volume, n is
yanalaym [24]

Answer:

Units of a = \frac{atm\ L^2}{mol^2}

Units of b = \frac{L}{mol}

Explanation:

The Van der Waal's equation  is:-

\left(P+\frac{an^2}{V^2}\right)\left(V-nb\right)=nRT

Where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value

a and b are van der Waal's constant

If pressure is taken in atm and volume in L. So,

P+\frac{an^2}{V^2} represents the pressure correction term. Then,

Units of a = \frac{atm\ L^2}{mol^2}

V-nb represents the volume correction term. Then,

Units of b = \frac{L}{mol}

Cancer cells grow so rapidly thatthey have a higher rate of anaerobic metabolism than most body tissues, especially at the cente
kupik [55]

Answer:

No, you cannot

Explanation:

One of the major properties a cancer drug must have is that, it must be highly specific. If a drug that poisons enzymes of anaerobic metabolism is used on a cancer patient, it should be noted that the drug will not only kill cancer cells but will also kill under cells that make use of anaerobic metabolism. Hence, this drug is not a specific to cancer cells but will also affect other normal cells in the patient's body. Thus, it would be wrong to use such drugs to treat cancer.

Find the hydrogen ion and hydroxide ion concentration in 0.02M solution of tetraoxosulphate(vi) acid.
77julia77 [94]

Answer: 0.04M

Explanation:

Tetraoxosulphate(VI) acid has a formula of H2SO4.

The concentration of the whole acid is 0.02M, and there are 2 hydrogens in the formula. That means we multiply 0.02M * 2, giving the answer of 0.04M.

Another visual explanation...

H2SO4 = H2(2+) + SO4(2-)

There are two hydrogens, the double amount of concentration of H2SO4, giving the answer of 0.04M.
