Matter and energy, and both these things are made up of atoms
It is a good idea because when mercury heats up, the molecules spread farther apart. Therefore, making them look to have expanded. Thermometers that are digital use a sensor to, as you would say feel the temperature around it.
Answer:
100 g of water has the highest number of moles
Explanation:
Recall that the number of moles is obtained as given mass/formula weight
For HCl;
number of moles = 100g/36.5g/mol = 2.7 moles
For H2O;
number of moles = 100g/18g/mol = 5.5 moles
For MgCO3
number of moles = 100g/84.3 g/mol = 1.2 moles
For AlCl3
number of moles = 100g/133.3g/mol = 0.75 moles
For NaCl
number of moles = 100g/58.4 g/mol = 1.7 moles
Answer:
28.6
Explanation:
Step 1: Write the balanced reaction at equilibrium
CO(g) + Cl₂(g) ⟺ COCl₂(g)
Step 2: Calculate the equilibrium partial pressure (in atm) of phosgene?
We will use the expression for the pressure equilibrium constant (Kp)
Kp = pCOCl₂ / pCO × pCl₂
pCOCl₂ = Kp × pCO × pCl₂
pCOCl₂ = 1.49 × 10⁸ × 4.38 × 10⁻⁴ × 4.38 × 10⁻⁴ = 28.6
