Pls help I'm marking brainliest for best answer Laundry Day Scientific Background
A chemistry student uses powdered laundry detergent, sodium carbonate (Na2CO3), when washing clothes. She accidentally poured epsom salt, magnesium sulfate (MgSO4), in the washing machine along with the laundry detergent. When both substances dissolved in the water, the student made observations.

Develop an argument explaining if the student observed a chemical reaction.
In your essay (3 paragraphs: one for each bullet) be sure to complete the following tasks:
- State whether or not a chemical reaction occurred and justify your claim using the student’s observations.
- Identify the reactants and products and explain what the (aq) and (s) represent in the equation.
- Determine the type of reaction that occurred in the washing machine and explain.

(Documents A through D are related to this Writing Task.)

Document A

Physical VS Chemical Changes

Document B

Observation #1
Epsom salt (MgSO4) and laundry detergent(Na2CO3) dissolved in the water
Observation #2
New tiny white solids formed at the bottom of the washing machine
Observation #3
The water feels hot when the epsom salt and laundry detergent solutions mix

Document C

MgSO4 (aq) + Na2CO3 (aq) → MgCO3 (s) + Na2SO4 (aq)

Document D

A + B → AB
AB → A + B
A + BC → B + AC
AB + CD → AD + CB
Hydrocarbon + O2 → CO2 + H2O
