It is becoming less expensive to screen blood samples for DNA. Certain diseases have a genetic basis. What is a possible ethical

concern about the availability of inexpensive DNA testing?
people may be treated differently if certain genetic information is known about them.

DNA testing may be too slow to actually be useful to doctors.

Some diseases are not thought to have genetic causes.

Cures for diseases may be developed with help from DNA research.

NeTakaya

Answer:

7.5 × 10¹⁵ Hz

Explanation:

Given data

  • Wavelength of the radio waves (λ): 40 nm = 40 × 10⁻⁹ m = 4.0 × 10⁻⁸ m
  • Frequency of the radio waves (ν): ?
  • Speed of light (c): 3.00 × 10⁸ m/s

We can determine the frequency of the radio waves using the following expression.

c = λ × ν

ν = c/λ

ν = (3.00 × 10⁸ m/s)/4.0 × 10⁻⁸ m

ν = 7.5 × 10¹⁵ s⁻¹ = 7.5 × 10¹⁵ Hz

Given the reaction below, how will the concentration of D change if the concentration of B decreases by 0.045 M? 3A(g)+2B(g)⇋2C(
abruzzese [7]

Answer:

0.113 M

Explanation:

Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:

[D]=\frac{5}{2}(0.045 M)=0.113 M.

Potassium hydrogen phthalate, KHC8H5O4, or KHP, is used in many laboratories, including general chemistry laboratories, to stand
Mamont248 [21]

Answer:

Molarity of the sodium hydroxide solution is 0.04687 M.

Explanation:

Amount of potassium hydrogen phthalate = 0.3420 g

Moles of potassium hydrogen phthalate =\frac{0.3420 g}{204.2 g/mol}=0.001675 mol

KHC_8H_4O_4+NaOH\rightarrow NaKC_8H_4O_4+H_2O

According to reaction, 1 mole of potassium hydrogen phthalate reacts with 1 mole of sodium hydroxide, then 0.001675 moles pf potassium hydrogen phthalate will :

\frac{1}{1}\times 0.001675 mol=0.001675 mol of NaOH

Moles of sodium hydroxide = 0.001675 mol

Volume of sodium hydroxide solution =  35.73 mL = 0.03573 L  (1 mL = 0.001 L)

Molarity=\frac{Moles}{Volume (L)}  

Molarity of the sodium hydroxide solution :

=\frac{0.001675 mol}{0.03573 L}=0.04687 M
