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.

A block of wood has a volume of 60 cm^3 and a mass of 240 grams calculate its density.
AlekseyPX

Answer:

4 g/cm³

Explanation:

Volume(V) = 60 cm³

mass (m) = 240 gm

density (d) = ?

We know density is defined as mass per unit volume so

d = m / v

= 240 / 60

= 4 g/cm³

Ammonium nitrate, a common fertilizer, is used as an explosive in fireworks and by terrorists. It was the material used in the t
Tamiku [17]

Answer:

The explosive decomposition of 98.4 kg of ammonium nitrate produces 58498.8 L of nitrogen, 29249.4 L of oxygen and 116997.6 L of water vapor.

Explanation:

To find how many liters of gas are formed from the explosive decomposition of ammonium nitrate it is necessary to follow these steps (check the attachment for better understanding):

1st) Balance the equation:

Write the decomposition equation and then find the correct coefficients to make sure that it goes according to the "Law of conservation of mass" (the mass of the reactants side must be equal to the mass of the products side). So, 2 moles of ammonium nitrate produces 2 moles of nitrogen, 1 mole of oxygen and 4 moles of water vapor.

2nd) Find the Ammonium nitrate molar mass:

The ammonium nitrate mass it is calculated by adding de molar mass of each atom that forms the ammonium nitrate molecule. You can find the elements molar mass in the Periodic Table.

In this example I decided to round the number to simplify tha calculus, for example: the oxygen molar mass in the periodic table is 15.9994 but I use 16. You can use the complete number if you want.

By doing this, the ammonium nitrate molar mass is 80 g/mol.

The statement says that there is 98.4 kg of ammonium nitrate. In ordder to use the same units in all the calculus sometimes it is usefull to convert the kg to g, so it is the same as 98400g. You can do it the other way around if you prefer (g to kg).

3rd) Find the number of moles of each gases and aqua vapor formed:

It is important to know the amount of each compound formed by the decomposition reaction, that's why we need to pay attention to the coefficients of the balanced reaction.

The amount of each compound is easily found by using the "rule of three".

To use the rule of three we need to think using the balanced reaction so:

If 160g (2 moles) of ammonium nitrate produces 2 moles of nitrogen gas, the 98400g that we have of ammonium nitrate will produce an X amount of nitrogen gas. With this information we multiply 98400g by 2 moles and then we divide the result by 160g. The final result it is 1230 moles of nitrogen.

In the same way we use the rule of three to calculate the number of moles of oxygen and water.  

4th) Find the liters (volume) of each gas and aqua vapor formed:

Finally, to find the liters from the number of moles, it is necessary to apply the "Ideal gases law", that relates the pressure (atm), volume (L), moles number and temperature (Kelvin) with the R gas constant in the formula:

PxV = nxRxT

It is important to use the correct units because the R gas constant is equal to 0.082 atm.L/mol.K.

As we need to calculate the liters (volume) we pass the pressure dividing to the other side and then we just have to replace the information:

V = (nxRxT)/P

As you can see in the attachment, doing this last step for each compound, we can find the liters produced of them.

Identify the gas law that applies to the following scenario: A 36.5 liter balloon holding 2.9 moles of carbon dioxide leaks. If
jarptica [38.1K]

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are <u>inversely</u> related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are <u>proportional</u>. We see this in the formula \frac{V1}{T1} = \frac{V2}{T2}.

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are <u>proportional</u>. We see this in the formula \frac{P1}{T1} = \frac{P2}{T2}.

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula \frac{V1}{n1} = \frac{V2}{n2}.

Plugging in the values based on Avogadro's Law, we'll have:

\frac{36.5}{2.9} = \frac{V2}{1.2}

12.6 = \frac{V2}{1.2}

12.6 x 1.2 = V2

15.1L =V2
