Answer:
Graduated cylinder
Explanation:
A tall skinny cylinder used to measure volumes. It is generally a more accurate way to measure volume than a typical beaker or flask. Mortar and pestle - A mortar and pestle are used to crush and grind solids into a powder. The mortar is a bowl and the pestle is a small club-shaped tool.
Not sure, but I believe it is... Sodium Nitrate?
Answer:
176 g of CO₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2C₂H₂ + 5O₂ —> 4CO₂ + 2H₂O
Next, we shall determine the mass of C₂H₂ that reacted and the mass of CO₂ produced from the balanced equation.
This is illustrated below:
Molar mass of C₂H₂ = (2×12) + (2×1)
= 24 + 2 = 26 g/mol
Mass of C₂H₂ from the balanced equation = 2 × 26 = 52 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32 = 44 g/mol
Mass of CO₂ from the balanced equation = 4 × 44 = 176 g
From the calculations made above,
52 g of C₂H₂ reacted to produce 176 g of CO₂.
