Answer:

1:   38

2:  39

3:  40

4:  41

Explanation:

The mass in amu is the weight of the neutrons and protons in the element.  The mass number is the number neutrons and protons you have in an element.  Both neutrons and protons have a weight of 1 amu.  Since you can't have a decimal of a subatomic particle, you have to round to the nearest whole number.

An inverse relationship can be represented by:<br> a straight line<br> a bar chart
kolezko [41]

Answer:

An inverse relationship can neither be represented by a straight line nor by a bar chart. But it can be represented by "xy = k"

Explanation:

                   Inverse relation is used for the values which are inversely related to each other. For example: Let suppose you have a value x and y. Then an increase in the value of x will result in the decrease of value y. Mathematically it is represented as,

                                                         x  ∝  1 / y

Where;

              ∝ = proportionality

Replacing the proportionality sign by a constant value "k" the relation becomes,

                                                         x  =  k / y

Solving for k,

                                                         x y  =  k

Conclusion:

                  Hence, an inverse relationship can be represented by "xy = k"

What is the partial pressure of C?<br> atm C
s344n2d4d5 [400]

The partial pressure of carbon is 45 mm Hg.

Explanation:

  • The partial pressure of carbon dioxide is referred as the amount of carbon dioxide present in venous or arterial blood. It acts as a ventilation in the lungs.
  • There is a formula for measuring partial pressure . As we know total pressure means summation of the pressure of all the gases included .
  • To find partial pressure we need- total pressure* fraction of mole of that gas. The partial pressure of CO2 is more because it carries deoxygenated blood from the whole body towards the lungs.
