The pressure of sulfur dioxide in a container is 159 kpa. what is this pressure in atmospheres?

Titanium has five common isotopes: 46Ti (8.0%), 47Ti (7.8%), 48Ti (73.4%), 49Ti (5.5%), 50Ti (5.3%). What is the average atomic

NNADVOKAT [17]

Hey there!:

Isotopes : abundance :

46 Ti 8.0%

47 Ti 7.8 %

48 Ti 73.4 %

49 Ti 5.5 %

50 Ti 5.3 %

Weighted average = ∑ Wa * % / 100

Therefore:

( 46 * 8.0) + (47 * 7.8 ) + (48 * 73.4 ) + ( 49 * 5.5 ) + ( 50*5.3 ) / 100 =

4792.3 / 100

= 47.923 a.m.u

Hope that helps!

If three potatoes have a mass of 667 g, what will be the mass of 100 potatoes? A. 200 kg B. 22.2 kg C. 2223 g D. 20.0 kg

adell [148]

Answer: B- 22.2 kg

Explanation: If three potatoes have mass of 667 g that means that each potato weighs 667/3= 222.33 g (approx) so 100 potatoes must be 100*222.33= 22233 g which equals 22.2 kg because 1 g=1000 kg

During normal, relaxed respiration, about 500ml of air enters and leaves the lungs with each respiratory cycle. this is called t

Marianna [84]

During normal respiration, about 500ml of air enters and leaves the lungs with each respiratory cycle. This is called the<u> tidal volume</u>.

When a person is relaxed, the normal amount of air such a person breathes in and out is called the tidal volume. It is usually measured in millimeters. For the average adult male, it is 500ml, and the tidal volume of average adult female 400ml.

In order to regulate oxygen intake and expulsion of carbon dioxide, the lungs act as buffers in order to absorb the maximum amount of oxygen possible for respiration and other metabolic functions in the body.

When the tidal volume is above or below the 500ml mark, it could signal the presence of underlying pathological conditions like bronchitis, emphysema and asthma.

A substance with a high [H ] would likely have which additional characteristics? a high [OHĂ˘â‚¬"" ] and a high pOH a low [OHĂ˘â

viktelen [127]

The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.

The substance having high $\rm [H]$ will have:

Option B. A low $\rm [OH ^{-}]$ and a high $\rm pOH$

This characteristic can be explained as:

The concentrations of $\rm [H^{+}]$ and $\rm [OH ^{-}]$ are inversely dependent on each other so when the concentration of raises then the concentration of $\rm [OH ^{-}]$ drops and vice versa.

The pH of a solution or substance is calculated with the help of:

$\rm pH = \rm - log \rm [H^{+}]$

From the formula, it can be deduced that when the concentration of $\rm [H^{+}]$ is high then the pH has a low value and it means that the solution is acidic.

pH can also be written as:

$\rm pH + pOH &= 14 \\\\\rm pOH &= 14 - pH$

From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.

Therefore, when pOH is in high concentration then $\rm [OH ^{-}]$ is low.
