Human blood has a pH between 7.35 and 7.45. Which of the following best describes human blood?
uysha [10]

Answer:

C. slightly basic

Explanation:

0-7 = acidic

7 = neutral

7-14 = basic

- Since the pH is just over 7, the answer would be slightly basic.

- Hope this helps! Please let me know if you need a further explanation.

An acetylene tank has a volume of 390.0 L. It is stored at a temperature of 23.5 °C and has a
xeze [42]

Considering the ideal gas law,  there are 279.42 moles of acetylene in the tank.

<h3>Definition of ideal gas</h3>

Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.

<h3>Ideal gas law</h3>

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:

P×V = n×R×T

<h3>Moles of acetylene</h3>

In this case, you know:

  • P= 1765 kPa= 17.4192 atm (being 101.325 kPa= 1 atm)
  • V= 390 L
  • n= ?
  • R= 0.082 \frac{atmL}{molK}
  • T= 23.5 °C= 296.5 K (being 0 °C= 273 K)

Replacing in the ideal gas law:

17.4192 atm× 390 L = n×0.082 \frac{atmL}{molK}× 296.5 K

Solving:

n=\frac{17.4192 atmx 390 L}{0.082 \frac{atmL}{molK}x296.5 L}

<u><em>n= 279.42 moles</em></u>

Finally, there are 279.42 moles of acetylene in the tank.

A different element has chemical properties that are similar to the properties of sodium. Which of the following statements abou
Ganezh [65]

Answer:I think it's in the same column as a sodium on the periodic table because chemical properties are based on their electron structure and the columns called groups are elements with the same shell structure which increases in mass as you go down the column, therefore the elements which are similar to sodium must be in the same group.
