Answer:
1.33L of gas
Explanation:
1 mole of Baking soda (NaHCO₃) reacts with acetic acid producing 1 mole of CO₂, water and sodium acetate, thus:
NaHCO₃ + CH₃COOH → NaCH₃COO + H₂O + CO₂
5g of NaHCO₃ (Molar mass: 84g/mol) are:
5g × (1mol / 84g) = 0.0595 moles of NaHCO₃ that produce 0.0595 moles of CO₂ -Moles of gas-.
If 1 mole of gas occupies 22.4L, 0.0595 moles occupy:
0.0595 moles gas × (22.4L / mol) = <em>1.33L of gas</em>
Mixture. Mixtures can be both heterogeneous and homogeneous. Heterogeneous mixtures are mixtures that don't have a fixed composition, meaning that if you take smaller samples from two different parts of a larger sample, the ratios of the substances will differ.
Heat pumps most do work on a refrigerant in order to reverse the normal flow of thermal energy.
Answer: 20 + 1 + 3.8 + 2.4 +27 = 54.2
Explanation: 20 gallons plus 1 gallon plus 3.8 plus 2.4 plus 27 equals to a total number of 54.2 gallons for the propane.
So the mole number of 319 ml of 6.80 M HCl is 6.80*319*10^(-3)=2.17 mol. So the volume of 6.00 M HCl needed is 2.17/6.00=0.362 L=362 ml
