The ph of body fluids must remain fairly constant for the body to maintain homeostasis.

Chemistry
1 answer:
andrew11 [14]3 years ago
4 0

Answer:

The answer is True

Explanation:

The Ph of bady fluids have different ranges but it should be nearly constant to maintain the health of the human, The PH of the human blood is from 7.35 to 7.45 and the other blood fluids have different ranges . The PH shouldn't drop below 6.9 because it is so dangerous for human health and result coma. if there is high value of PH this indicates high numbers of OH- and low value of PH  this indicates high numbers of H+

each organ has a certain PH value to do its function very well ,there is an organ needs acidic environment to work well and other organ needs an alkaline environment to do its work.

Select the correct answer. What is heat of vaporization? A. It is the heat required to change a substance’s temperature by 1°C.
Luba_88 [7]

D. It is the heat required to change a gram of substance from a liquid to a gas.

Explanation:

The heat of vaporization is the heat required to change a gram of substance from a liquid to a gas.

  • It is also known as the enthalpy of vaporization.
  • The heat of vaporization is the quantity of heat needed to change one gram of a substance from liquid to gas.
  • This heat of vaporization is dependent on the pressure conditions the process is taking place.
  • Different liquids have their heat of vaporization.

3. Find the wavelength if the energy of light is 3.36x10 to the -17th power J.
telo118 [61]
<h3>Answer:</h3>

1.52 × 10⁻¹⁶ nm

<h3>Explanation:</h3>

We are given,

Energy = 3.36 × 10⁻¹⁷ Joules

We are required to find the wavelength of light

We are going to use,

The formula, E = hλ/c

Where E is the energy, λ is the wavelength, h is the plank's constant and c is the speed of light.

h = 6.626 × 10^-34 J-s

c = 2.998 × 10^8 m/s

Working

From the formula;

Wavelength=\frac{Ec}{h}

 = (3.36 × 10⁻¹⁷ J)(2.998 × 10^8 m/s) ÷ 6.626 × 10^-34 J-s

= 1.52 × 10⁻²⁵ meters

Therefore, the wavelength in m is 1.52 × 10⁻²⁵ m

Conversion

We need to convert m to nm

Conversion factor is 10⁹

Therefore;

1.52 × 10⁻²⁵ m to nm

will be; 1.52 × 10⁻²⁵ m × 10⁹

  = 1.52 × 10⁻¹⁶ nm

Thus, the wavelength in nm is 1.52 × 10⁻¹⁶ nm

Is plastic a mixture, compound, or an element?
Drupady [299]
Plastic could not be considered an element because elements are pure substances,Plastic is best described as a compound because its elements cannot be separated like the elements in a mixture can, without undergoing a chemical reaction.
