Answer:
Red.
Explanation:
- Methyl orange is an organic dye that used as an indicator in acid-base titrations because its color is changed according to the pH of the medium (acidic, neutral or basic).
- Methyl orange is red in acidic solutions, orange in neutral solutions, and yellow in basic solutions.
<em>Since, pH of the solution is 2, the solution is acidic, the color of the solution will be red.</em>

A calorimeter contains 500 g of water at 25°C.....
the temperature of the water inside the calorimeter is 39.4°C.....
The specific heat of water is 4.18 J/g-°C.
energy needed to heat the water = specific heat * mass * temp difference
= 4.18 J/g-°C * 500 g * (39.4°C - 25°C)
= 4.18*500*14.4
= 30096J
or approx. 30kJ

Answer:
Explanation:
Hello,
In this case, since we have grams of iron (III) oxide whose molar mass is 159.69 g/mol are able to compute the produced grams of iron by using its atomic mass that is 55.845 g/mol and their 2:4 molar ratio in the chemical reaction:
