What is oxidized in the reaction below? H2 + Cl2 → 2HCl

Chemistry
1 answer:
natima [27]2 years ago
3 0

Answer: Cl2 is acting as an oxidizing agent.

Explanation:

Hydrogen reacts with Chlorine to produce Hydrochloric Acid.

                                H2 + Cl2 ---> 2 HCl

Oxidation Reaction: Hydrogen's oxidation state in H2 is changing from 0 in H2 to +1 in HCl per atom. That means that it has lost one electron per atom and two electrons per molecule. Therefore, hydrogen is oxidized and has acted as a reducing agent.

                                H2 ---> 2 HCl + e-

Reduction Reaction: Chlorine's oxidation state in Cl2 is changing from 0 in Cl2 to -1 in HCl per atom. This means that it loses one electron per atom and two electrons per two atoms. Therefore, Chlorine is reduced and has acted as an oxidizing agent.

Identify the polynomial.<br><br> x3- y3 + z<br><br> monomial<br><br> binomial<br><br> trinomial
Firdavs [7]

Answer: Option (c) is the correct answer.

Explanation:

A monomial is defined as an algebraic expression in which there is only one term present.

For example, 3x is a monomial.

A binomial is defined as an expression where there will be two terms present. For example, (x^{2} + y^{2}) is a binomial.

A polynomial is defined as an algebraic expression which contains more than two terms.

For example, x^{3} - y^{3} + z is a polynomial.

Thus, we can conclude that the given expression x^{3} - y^{3} + z is a polynomial.

If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?
Darina [25.2K]

The question is incomplete, here is the complete question:

A bottle of rubbing alcohol having aqueous solution of alcohol contains 70% (v/v) alcohol. If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

<u>Answer:</u> The amount of water present in the given bottle of rubbing alcohol is 283.8 mL

<u>Explanation:</u>

We are given:

Volume of bottle of rubbing alcohol = 946 mL

70% (v/v) alcohol solution

This means that 70 mL of rubbing alcohol is present in 100 mL of solution

Amount of water present in solution = [100 - 70] = 30 mL

Applying unitary method:

In 100 mL of solution, the amount of water present is 30 mL

So, in 946 mL of solution, the amount of water present will be = \frac{30}{100}\times 946=283.8mL

Hence, the amount of water present in the given bottle of rubbing alcohol is 283.8 mL

The data showed that recently the alligator population has decreased. How could the decrease in the alligator
Marina CMI [18]

Answer:

Since the alligator population decreased, this means there are less predators for the gar. Less predators for the gar mean the gar population will increase.  More gar also means more competition for the diving duck in terms of animals that eat crabs, and thus the diving duck population will also decrease.

A block of gold is illuminated with UV light at a wavelength of 1.6x10-11 meters. What is the frequency of this light ?
irga5000 [103]

Answer:

f = 1.87 × 10¹⁹ s⁻¹

Explanation:

Given data:

Wavelength of light = 1.6 ×10⁻¹¹ m

Frequency of light = ?

Solution:

Formula:

speed of light = wavelength × frequency

Frequency = speed of light / wavelength

speed of light = 3× 10⁸ m/s

Now we will put the values in formula:

Frequency = speed of light / wavelength

f =  3× 10⁸ m/s / 1.6 ×10⁻¹¹ m

f = 1.87 × 10¹⁹ s⁻¹
