True.
For example: Sodium oxide and Nitric acid; both compounds contain oxygen.
Answer:
sodium hydroxide is the limiting reactant
Explanation:
The first step is usually to put down the balanced reaction equation. This is the first thing to do when solving any problem related to stoichiometry. The balanced reaction equation serves as a guide during the solution.
2NBr3 + 3NaOH = N2 + 3NaBr + 3HOBr
Let us pick nitrogen gas as our product of interest. Any of the reactants that gives a lower number of moles of nitrogen gas is the limiting reactant.
For nitrogen tribromide
From the balanced reaction equation;
2 moles of nitrogen tribromide yields 1 mole of nitrogen gas
4.3 moles of nitrogen tribromide will yield 4.3 ×1/ 2 = 2.15 moles of nitrogen gas
For sodium hydroxide;
3 moles of sodium hydroxide yields 1 mole of nitrogen gas
5.9 moles of sodium hydroxide yields 5.9 × 1/ 3= 1.97 moles of nitrogen gas
Therefore, sodium hydroxide is the limiting reactant.
This is going to be a <em>phase </em>change!
Answer:
Acknowledge the source of relative weight of titanium.
Explanation:
Titanium is a chemical element which durable form of metal. Titanium is 45% lighter than steel. Titanium is made by combination of multiple elements. Titanium is very difficult to extract and this is the reason this element is considered expensive. The students examining the titanium must record the weight of titanium before exploring the characteristics and properties.
