Answer:
150
Explanation:
- C₄H₂OH + 6O2 → 4CO2 + 5H₂O
We can <u>find the equivalent number of O₂ molecules for 100 molecules of CO₂</u> using a <em>conversion factor containing the stoichiometric coefficients of the balanced reaction</em>, as follows:
- 100 molecules CO₂ *
= 150 molecules O₂
150 molecules of O₂ would produce 100 molecules of CO₂.
Answer:
-
Explanation:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
Answer:
mass of carbon-dioxide = 0.262 g
Explanation:
Firstly, write the chemical equation of the reaction and balance the equation accordingly.
2NaHCO3(aq) → CO2(g) + H2O(l) + Na2CO3(aq)
Calculate the molecular mass of baking soda
molar mass of baking soda = 23 + 1 + 12 + 48 = 84 g
2 moles of baking soda = 2 × 84 = 168 g
molar mass of CO2 = 12 + 32 = 44 g
if 168 g of baking soda produces 44 g of carbon-dioxide
1 g of baking soda will produce ? grams of carbon-dioxide
cross multiply
mass of carbon-dioxide = 44/168
mass of carbon-dioxide = 0.2619047619
mass of carbon-dioxide = 0.262 g
