IBSL Chemistry Questions & Answers

What will be the temperature change, T2, for a second experiment in which the amount of NaOH and the volume of 1.0 mol dm−3 HCl are each doubled? When 0.01 mol of solid NaOH is added to 100 cm3...
The correct answer to this question is A, T2=∆T1. Temperature changes are one of many ways an indication of a chemical change is occurring. Other signs include a change in color, an odor, and bubbles forming. These changes aren't able to be seen bu
What mass of hydrogen will be obtained if 100 cm^3 of 2.00 mol.dm^-3 HCl is added to 4.86g of magnesium? Magnesium reacts with hydrochloric acid according to the following equation: Mg(s) ...
The answer to this question is A. This is a type of limiting reactant problem wherein the acid is in deficiency. Half of the dihydrogen will evolve depending on the amount that will be placed. To determine the moles of magnesium, you need to divide t
Which statement(s) is/are true for a mixture of ice and water at equilibrium? I. The rates of melting and freezing are equal. II. The amounts of ice and water are equal. III. The same position of...
An equilibrium in science refers to the elements on all side of the situation are balanced. One element doesn’t overpower another item. They are all balanced and the same. There are times that a mixture of ice and water can reach an equilibrium
Which is not a true statement?
It is not true to say the one mole of hydrogen gas contains 6.02x 10^23 atoms of hydrogen. However, some true statements that involve hydrogen would be that one molecule of methane contains four moles of hydrogen atoms, one mole of carbon 12 has a ma
