False. only valence electrons can bond with other atoms' electrons.
The partial pressure of the gas will be the total pressure minus the vapor pressure. 523.8-23.8=500mmHg. This makes sense due to the fact that the idea of partial pressures still works even with vapor pressure since vapor pressure is just the partial pressure of water vapor (23.8mmHg) in the container which is added to the partial pressure of hydrogen gas (500mmHg) to make a total pressure of 523.8mmHg.
I hope this helps. Let me know in the comments if anything is unclear.
Answer:
Two
Explanation:
In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products.
Answer:
digestion
Explanation:
he mouth. Digestion begins even before the food enters the mouth.
Answer:
The molality of the solution is 3.45 mol/kg
Explanation:
Molality is a type of concentration which shows the moles of solute contained in 1 kg of solvent.
Moles of salt (KCl) = 1.12 moles
Moles of solvent (H₂O) = 18 moles
Let's convert the moles of solvent to mass (mol . molar mass)
18 m . 18g/m = 324 grams
We convert grams to kg → 324 g / 1000 = 0.324 kg
Now we can reach molality
1.12mol / 0.324 kg = 3.45 m
