1 is D - double-replacements do not make solid metals
2 is A - to have complete combustion the original compound must ONLY have C, H and O
3 is B - the elemental Mg replaces the H in the HCl

The first one is going to likely be A because this is what happens in a precipitation reaction, not in a double replacement reaction. The second one is A because that is Methane, which is a source of fuel. The complete combustion formula is Oxygen + fuel, resulting in CO2 and H2O. The final one is a single-replacement reaction. Hope this helps!

A frequency of 60 MHz is close to the lower end of the old VHF-TV band.


c = f λ ...... where c is the speed of light, f is the frequency and λ is the wavelength

λ = c / f = 3.00x10^8 m/s / 6.0x10^7 1/s

λ = 5.0 m

In bohr's atomic theory, when an electron moves from one energy level to another energy level more distant from the nucleus,
labwork [276]

Answer is: energy is absorbed.

According to the Bohr model of the atom:

1. Electrons orbit the nucleus in orbits that have a set size and energy.

2. Energy levels of electrons are discrete (certain discrete values of energy).

3. Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).
