Answer:

The product of this reaction is the hydrochloric acid

Explanation:

The compounds required to perform a reaction are the reactants, in this case there are two: hydrogen and chlorine.

The resultant compound is denominated the product. In this case, the hydrochloric acid.

The reaction is:

$Cl_2 + H_2 \longrightarrow 2 HCl$

11. if the ph of a solution increases from 2.0 to 4.0, the h3o^ ion concentration o a decreases by a factor of 2. b. decreases b

Wittaler [7]

Option (B) is the right answer.

Hydronium ion ( $H_{3}O^{+}$ ) concentration decreases by the factor of 100, if the pH of a solution increases from 2.0 to 4.0.

The hydrogen ion concentration in water is expressed by pH. Specific to aqueous solutions, pH is the negative logarithm of the hydrogen ion (H+) concentration (mol/L) : $pH = -log_{10}[H_{3}O^{+} ]$

Acidic solutions are those with a pH under 7, and basic solutions are those with a pH over 7. At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.

<h3>Given: </h3>

pH1( initial pH) = 2.0

pH2( initial pH) = 4.0

[H3O+] = initial hydronium concentration

[H3O+]* = final hydronium concentration

<h3>Formula used : </h3>

$pH = -log_{10}[H_{3}O^{+}]$

<h3>Solution: </h3>

$pH = - log_{10}[H_{3}O^{+}] \\\\= > 10^{-pH} = [H_{3}O^{+}] \\\\similarly, \\\\10^{-pH} = [H_{3}O^{+}]*\\\\ = > 10^{-4} = [H_{3}O^{+}]*\\\\Now, \frac{[H_{3}O^{+}]*}{[H_{3}O^{+}]} = 10^{-2}$

Thus , the concentration of hydronium ion decreases by 100.

When a chemical reaction take place new atom or new element are formed true or false

Andreas93 [3]

In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change. A chemical reaction is a mechanism that takes place when two or more molecules interact to produce new products. A reaction between two atoms or ions or molecules may take place and a new bond is formed and no atom is destroyed or created, but reactants form a new substance.

I am a subatomic particle that is positively charged what am I?

lions [1.4K]

The right answer is Proton.

Additional Information:

There are three types of subatomic particles. They are:

Proton
Electron
Neutron

Proton is a positively charged particle,Electron is negatively charged particle and Neutron is charge less.

Hope it will be helpful to you...

What is relative velocity expalin with an examle

Nikitich [7]

Answer:

Explanation:For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east. ... Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”
