The pressure exerted by each individual gas in a mixture of gases is called its <u>partial </u>pressure this pressure is proportional to the <u>mole</u> fraction of the gas in the mixture

Pressure is defined as the force of all the gas particle of wall collisions divided by the area of the wall

The pressure exerted by an individual gas in a mixture is known as its partial pressure and assuming we have a mixture of ideal gases and we can use the ideal gas law to solve problems involving gases in a mixture and the ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components

Is NaBr+I2 -&gt; NaI+Br2 a single replacement
snow_lady [41]

Is not a single replacement

<h3>Further explanation</h3>

A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

Reactions

A+BC--> AC+B

Metal halogens can force metal halide ions in the order F> Cl> Br> I

Oxidation : F₂> Cl₂> Br₂> I₂

Reaction

NaBr+I₂ -> NaI+Br₂

Then the reaction will not occur because I₂ cannot oxidize Br, or the reaction is said to be non-spontaneous

Answer:

Q1: Bubbles (gas formation)

     Dissolving ( if solute is an ionic compound)

     Color change

Q2: Fire burning

      Salt dissolving

Q3: Bubbles (gas formation)  

       Color change

      Dissolving ( if solute is an ionic compound)

Explanation:

Bubbles (gas formation)

Gas formation is mostly taken as an indicator for a chemical reaction, mostly in acid base reactions. Because when acid and base reacts water and carbon dioxide produces.

Dissolving of salt

Dissolving of salt in water is an example of a chemical change. Because when we put salt (NaCl) in water it changes into its ions (Na⁺ Cl⁻) by losing or gaining electrons. These Ions have totally different properties from the parent salt. So it is a chemical change.

Color change

Mostly we take color change as an indicator of a chemical change but it is not necessary. For example when we add two colors in a beaker its changes into a 3rd color without any chemical reaction.

Fire burning

Fire burning is an example of a chemical change. For example during wood burning, a chemical reaction takes place which changes the into ash and CO₂. the reactants and products have totally different properties.

What is the electron geometry of CO2 ?
Lisa [10]

CO2 has a linear geometric shape due to the two sigma bonds between the carbon and oxygen valence electrons. Both oxygen molecules are sp2 hybridized meaning they both have one sigma bond and two pairs of un bonded electrons.

Which of the following explains why there are so many differences in the properties of peptides and proteins? a) Several amino a
MatroZZZ [7]
I think the answer is a). While though peptides and proteins are formed by amino acids. But the proteins have more complex structure than peptided and this leads to the higher function of proteins over peptides.
