Answer: It’s a bad conductor of electricity
Explanation:
The Answer is A
This is because sodium needs to give off one electron to be stable, form these options the only element that needs to take one electron to be stable is fluorine thus A is the answer
Answer:
empirical formula is C7H3NCl2
Explanation:
too much work too explain and im lazy
Answer:
Partial pressure of CO₂ is 406.9 mmHg
Explanation:
To solve the question we should apply the concept of the mole fraction.
Mole fraction = Moles of gas / Total moles
We have the total moles of the mixture, if we have the moles for each gas inside. (3.63 moles of O₂, 1.49 moles of N₂ and 4.49 moles of CO₂)
Total moles = 3.63 mol O₂ + 1.49 mol N₂ + 4.49 mol CO₂ = 9.61 moles
To determiine the partial pressure of CO₂ we apply
Mole fraction of CO₂ → mol of CO₂ / Total moles = P. pressure CO₂ / Total P
Partial pressure of CO₂ = (mol of CO₂ / Total moles) . Total pressure
We replace values: (4.49 moles / 9.61 moles) . 871 mmHg = 406.9 mmHg
Answer:
b. colloid
Explanation:
Colloids are solutions that are going to have a solute and a solvent, but the size of the particles are bigger than in a solution that is clear. that is the reason that it looks blurred because the particles are bigger.
In the other hand, these particles of the solute are big, but not so big and heavy as in a suspension, so they are not going to precipitate in the bottom.
The movement of the particles are called Brownian movement, and they are the responsible to avoid to settle down at the bottom of the recipient.
