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
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.
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.

D is the correct process to convert 36 yds to centimetres 2.54 cm = 1 in.
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.
