Answer:
Ionul de hidroniu este un factor important atunci când avem de-a face cu reacții chimice care apar în soluții apoase. Concentrația sa în raport cu hidroxidul este o măsură directă a pH-ului unei soluții. Se poate forma atunci când un acid este prezent în apă sau pur și simplu în apă pură. Formula chimică este H3O +
Explanation:
The hydronium ion is an important factor when dealing with chemical reactions that occur in aqueous solutions. Its concentration relative to hydroxide is a direct measure of the pH of a solution. It can be formed when an acid is present in water or simply in pure water. It's chemical formula is H3O+

Answer:
0.208mole of CO2
Explanation:
First, let us calculate the number of mole of HC3H3O2 present.
Molarity of HC3H3O2 = 0.833 mol/L
Volume = 25 mL = 25/100 = 0.25L
Mole =?
Mole = Molarity x Volume
Mole = 0.833 x 0.25
Mole of HC3H3O2 = 0.208mole
Now, we can easily find the number of mole of CO2 produce by doing the following:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
From the equation,
1mole of HC2H3O2 produced 1 mole of CO2.
Therefore, 0.208mole of HC2H3O2 will also produce 0.208mole of CO2
Statement:
The best way to measure the mass of an orange is to use a balance. You put the orange and the mass pieces in the same cup on the balance and find out how many centimeters it is. The mass of my orange was 145.
Explanation:
Problem 1
The student has not done a good job in measuring the weight of the orange. In fact, the has complicated his simple problem.
Reasons:
- Using the mass pieces and the cup to find the weight of the orange is wrong approach.
He can easily place the orange on the balance and read off the weight.
- Centimeters is a unit of length. What length is he measuring and recording?
The unit of weight is in newtons(N).
- Mass is not read from a balance. A balance gives the weight of substance. Mass is different from weight.
Problem 2
Rewriting to paragraph to correct the errors:
The best way to measure the mass of an orange is to use a balance. You put the orange on the balance and find out how many newtons it is. The weight in newtons can be converted to mass in kilogram. The mass of my orange will be 145kg.
