Answer:
Explanation:
Molar mass of NaCl = 58.44 g/mol
Mass of NaCl = 195 g
Volume of solution = 4.05 L
Molarity of solution is
The molarity of the solution is
Moles of NaCl = 4.63 mol
Volume is given by
The volume of the solution that contains the required amount NaCl is
Volume of solution = 
Moles of solution is given by
The number of moles of NaCl is .
Answer:
Boyle's Law is a relationship between pressure and volume. In this relationship, pressure and volume have an inverse relationship when temperature is held constant. If there is a decrease in the volume there is less space for molecules to move and therefore they collide more often, increasing the pressure.
Explanation:
Their outer most orbital has 2 (for helium) or 8 electrons, making it not need to bond with other atoms to become stable.
Answer:
1.3 moles of HNO₃ will be produced
Explanation:
Equation for the reaction:
3NO₂ + H₂O ----> 2HNO₃ + NO
From the equation of the reaction, 3 moles of NO₂ reacts with 1 mole of H₂O to produce 2 moles of HNO₃
Suppose there are 2 moles of NO₂ and 7.0 moles of H₂O in a reactor, the limiting reactant will be NO₂ and H₂O will be in excess since 3 moles of NO₂ reacts with every 1 mole of H₂O.
Since 3 moles of NO₂ reacts to produce 2 moles of HNO₃;
2 moles of NO₂ will react to produce 2/3 * 2 moles HNO₃ = 1.3 moles of HNO₃
Therefore, 1.3 moles of HNO₃ will be produced
Rubisco is a super important enzyme in plants that first captures CO2 to begin the process of the Calvin cycle. It's the most important enzyme by far because it starts the entire process of Carbon Fixation.
