Answer:
It's called a theory because it has not been proven yet. so we can not claim it to be a fact without proof.
Answer:
V = 11.2 L
Explanation:
Hello there!
In this case, according to the ideal gas equation:
It is possible to compute the volume as shown below:
Whereas the moles are computed are computed given the mass and molar mass of oxygen:
Now, since the STP stands for a temperature of 273.15 K and a pressure of 1 atm, the resulting volume is:
Best regards!
Weather is the temperature or climate over a short period of time.
Answer:
The anion of the compound is b CH3COO-
Explanation:
The compound cupric acetate Cu(CH3COO)2 undergo dissociation to form cupric ion Cu2+ and Acetate anion(CH3COO-)
Cu(CH3COO)2⇒ Cu2+ + CH3COO-
From the above equation it can be stated that the anion of Cu(CH3COO)2 is CH3COO-.
Answer:
See explanation
Explanation:
If the energy of the ground state E1 is known, then we need to measure the difference in energy between the energy levels E5 .and E1. We can obtain this by measuring the frequency or wavelength of a photon that is emitted when an electron moves from energy level E5 to E1.
From Bohr's model;
ΔE = E5 - E1
Hence;
E5 = ΔE + E1
