What is a mixture in which something is dissolved in a liquid ?

Answers

Answer 1

Answer: This mixture is called a solution. A solution is a homogeneous mixture that is liquid which a solute is uniformly distributed in a solvent. When the solvent is water, this is called an aqueous solution. Solutions may contain one or more solute.

A student investigated the rate of reaction between sodium thiosulphate and dilute hydrochloric acid the student placed a conical flask over a cross on a piece of paper
the student mixed the solutions in the flask
the solution went cloudy
the student timed how long it took until the cross could not be seen
the equation for the reaction is :
Na2 S2O3(aq) + 2HCl(aq) = 2NaCl(aq) + H2O(l) + SO2(g) + S(s)
explain why the solution goes cloudy

Answers

Na₂ S₂O₃ ( aq ) + 2HCl ( aq ) = 2NaCl ( aq ) + H₂O ( l ) + SO₂ ( g ) + S ( s ) this solution goes cloudy because the student placed a conical flask over a cross on a piece of paper.

What is rate of reaction ?

The speed at which a chemical reaction occurs is known as the reaction rate or rate of reaction. It is proportional to the rise in product concentration per unit time and the fall in reactant concentration per unit time. Reaction times might differ significantly.

The norm is to write reactant or product]to indicate the concentration of any reactant or product, respectively. Therefore, A's concentration may be represented as A, and B's concentration as [B]. Assume that the reaction starts at time t =0 , which is the start time.

Regarding Hcl, the reaction rate is zero-order. To get rid of the sulfur, empty the beakers and give them a good cleaning with paper towels.

Sulphur dioxide, sodium chloride, sulphur, and water are the products of the reaction between sodium thiosulphate and diluted hydrochloric acid. Sulfur dioxide is a gas with the capacity to entirely dissolve in aqueous solutions.

Thus, option A is correct.

What are centimetres?

A metric unit of length, equal to one-hundredth of a metre.

To convert a yard measurement to a centimetre measurement, multiply the length by the conversion ratio. The length in centimeters is equal to the yards multiplied by 91.44.

What do elements and compounds have in common? And how do they differ?I will mark brainliest for the best answer.

WARNING: DON'T PUT LINKS I WILL REPORT YOU!

Answers

elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances. Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.

What interacted directly with the photographic plates to cause images in Becquerel’s experiment?A...uranium salt

B...radiation

C...unstable nuclei

D...radioisotopes

Answers

Answer: A. uranium salt

Becquerel made a conclusion that it was the uranium that causes the images found in the photographic plates. Though his theory was disproved during the first time,he continued to develop it. Then, it is through this experiment that Becquerel discovered radioactivity.

C6H14 has a boiling point than C11H24.

Answers

The correct statement to complete the thought of the sentence is "lower boiling point". C6H14 or hexane has a lower boiling point than C11H24 since hexane has lower number of atoms than the latter. Lower number of atoms means less bond which results to lower bonds to break.

C6H14 has a lower boiling point than C11H24.
