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.

Answer:

The sickle cell gene is recessive to the normal gene

Please find the description below

Explanation:

Sickle cell is a blood disease inherited genetically from one's parents. The sickle cell is associated with the blood genotype of an individual. The allele for sickle cell trait is S, while that of the normal gene is A. In this gene, the allele for normal gene (A) is dominant over the allele for sickle cell (S).

Hence, people that have one sickle cell gene (S) and one normal gene (A) will have an AS genotype. The individual will have few defective cells and no symptoms because the phenotypic expression of the sickle cell allele has been masked by the normal one.

Answer:

80g=0.08kg

20cm=0.02m

density=m/v

= 0.08/0.02

=4kg/m^3

it is less than density of water so it floats

Answer:

Fe+CuSO4 ⇒ FeCu+SO4

Answer:

Fe + CuSO4 = Fe2 (SO4)3 + Cu - Chemical Equation Balancer

Explanation:

To balance Fe + CuSO4 = Cu + FeSO4 you'll need to be sure to count all of atoms on each side of the chemical equation. When we balance equations with polyatomic ions, like SO4 2- it is helpful to consider the SO4 as one item as long as there is a SO4 on both sides of the chemical equation.

Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation.

Important tips for balancing chemical equations like Cu + FeSO4 | Iron and Copper(II) Sulfate:

- Only change the numbers in front of compounds (the coefficients).

- Never change the numbers after atoms (the subscripts).

- The number of each atom on both sides of the equation must be the same for the equation to be balanced.

Explanation:

The neutral aluminium atom loses all 3 of its valence electrons to obtain a stable octet structure.

The aluminium ion has a positive charge of 3.

=> Al3+, Charge = +3.

Answer:

17 decrease

18 increase

19 increase

20 decrease

Explanation:

Answer: these are for questions 1,2,4,5,7

Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.

number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.

hope this helps :))

Answer:

Magnesium, calcium and sodium.

Explanation:

Magnesium, calcium, sodium, and other beneficial minerals are the substances present in drinking water. Different regions have different fluoride concentration in their water such as in sea water, fluoride level is 1.1 mg/L while in surface water, the concentration is 0.01–0.3 ppm. Yes, fluoride is soluble in water. No, fluoride should not be added to drinking water because it harm for health. All the questions can be answered by science because it is related to chemistry.

Answer A. The electronegativity of one atom is less than 1.7

Answer: its C

Explanation: i just got it wrong the right answer is c

Answer: Option (b) is the correct answer.

Explanation:

It is known that,

                   pH + pOH = 14

So, pOH = 14 - pH

As the given pH is 9.3. Hence, pOH for the given solution will be calculated as follows.

          pOH = 14 - 9.3

                   = 4.7

Therefore, pOH of the given solution is 4.7.

A chemical equation is said to be balanced if the quantity of each type of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the charge are both equal. P₄ + 4NaOH + 2H₂O → 2PH₃ + 2Na₂HPO₃.

A chemical equation is said to be balanced if the quantity of each type of atom in the reaction is the same on both the reactant and product sides. In a balanced chemical equation, the mass and the charge are both equal.

A chemical equation must balance according to the rule of conservation of mass. According to the rule, mass cannot be generated or removed during a chemical process.

Answer:

About 140 gallons?

Explanation:

The abundance of isotope 35 = 75%

The abundance of isotope 37 = 25%

Ratio isotope 35 :  isotope 37 = 3 : 1

Given

Ar Cl = 35.5

Two isotopes of mass number 35 and 37

Required

The ratio of each isotope

Solution

If the abundance of isotope 35 is x%, then the abundance of isotope 37 is (100-x)%

35.5 = x%.35 + (100-x)%.37

35.5 = 0.35x+0.37(100-x)

35.5=0.35x-0.37x+37

0.02x=1.5

x=75

464 g radioisotope was present when the sample was put in storage

Given

Sample waste of Co-60 = 14.5 g

26.5 years in storage

Required

Initial sample

Solution

General formulas used in decay:  

[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}[/tex]

t = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

Half-life of Co-60 = 5.3 years

Input the value :

[tex]\tt 14.5=No.\dfrac{1}{2}^{26.5/5.3}\\\\14.5=No.\dfrac{1}{2}^5\\\\No=\boxed{\bold{464~g}}[/tex]

Answer:

∴ Q = -7.52kCal

Explanation:

Using the formula for specific heat capacity:

Q = mcΔT

where ΔT = change in temperature (final - initial)  = (0 - 100)°C = -100°C

m = mass (g) = 75g

c = specific heat capacity = 4.2 J/g°C in water

⇒ Q = 75 × 4.2 × -100

= -31,500J

But 1J - 0.000239kCal

∴ Q = -7.52kCal
