Answer:

Le football est mon sport préféré. C'est aussi un sport célèbre dans le monde entier. En jouant au football, nous pouvons garder notre corps fort, en forme et flexible, jouer au football est un bon exercice et bon pour la santé. Il a besoin d'un terrain spacieux. Le nombre de joueurs nécessaires pour ce jeu est de vingt-deux. Il y a deux groupes. Chaque groupe compte onze joueurs. Chaque groupe a un gardien de but. Il y a un centre à partir duquel le jeu commence avec l'arbitre. Il a le pouvoir de commenter le bien ou le mal. Les joueurs doivent respecter les règles du sport. Si un joueur lui désobéit, il est disqualifié et sort du terrain de jeu. Lorsque le but est marqué des supporters, la joie n’a pas de limite. Des applaudissements passionnants sont visibles lorsqu'un but est marqué. Cette pièce est originaire d'Angleterre. Ensuite, il s'est répandu dans presque tous les coins et recoins du monde. Sa popularité augmente de jour en jour.

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.

Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentratio

velikii [3]

<u>Answer:</u> The amount of CO that is occupied in the room is $1.98\times 10^3L$

<u>Explanation:</u>

We are given:

Concentration of CO = $8.00\times 10^2ppm=800pm$ by volume

This means that $800\mu L\text{ or }800\times 10^{-6}$ of CO is present in 1 L of blood

To calculate the volume of cuboid, we use the equation:

$V=lbh$

where,

V = volume of cuboid

l = length of cuboid = 10.99 m

b = breadth of cuboid = 18.97 m

h = height of cuboid = 11.89 m

$V=10.99\times 18.97\times 11.89=2478.83m^3$

Converting this into liters, by using conversion factor:

$1m^3=1000L$

So, $2478.83m^3=2.479\times 10^6L$

Applying unitary method:

In 1 L of blood, the amount of CO present is $800\times 10^{-6}$

So, in $2.479\times 10^6L$ of blood, the amount of CO present will be = $\frac{800\times 10^{-6}}{1}\times 2.479\times 10^{6}=1983.2L=1.98\times 10^3L$

Hence, the amount of CO that is occupied in the room is $1.98\times 10^3L$

Highlight the examples of radiation in the passage

BartSMP [9]

Answer:

Heating of the liquid water in a microwave.

Explanation:

Radiation is a form of heat transfer process that does not require a material medium rather it travels through space or vacuum in the form of electromagnetic waves or radiation. Heat transfer by radiation occurs in the form of microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. Some common examples of heat transfer by radiation is the warming of the Earth by the Sun, the warmth one experiences while sitting by the campfire, or the heating up of foods in a microwave.

Black bodies or surfaces are good absorbers as well as emitters of radiation. On the other shiny or white surfaces are poor radiators of heat.

From the above discussion on radiation, it can be seen that when the chemist takes the liquid and heats it in a microwave, the heat absorbed by the liquid to change to gaseous state is transferred through radiation.
