The correct answer is the octet rule.
Octet rule states that atoms tend to bond in order to have 8 electrons in their outer most electron orbit achieve stable configurations of noble gases.
When atoms form covalent bonds, they achieve the goal of having 8 electrons by sharing the electrons.
In ionic bond, atom either gain or lose an electron and form ions that have the stable configuration of 8 valence electrons.
Not all atoms follow the octet rule and there are many exceptions and variations.
Density is a ratio between the mass and the volume of a substance.It measures how much of a substance is packed into a set volume. Density increases when a larger amount of material is packed into a smaller volume. The same is true in opposite: density decreases when a smaller amount of a substance is packed into a larger volume.
To calculate density, we will take the total given mass of the substance and divide it by the total volume of its container.
In this problem, we have a mass of 86 grams and a volume of 25cm^3.
Density= mass/volume
Substitute the given values into the formula:
Density=86 grams/25 cm^3
Density=3.44 grams/cm^3
The density of the material is 3.44 g/cm^3.
Answer:
An oxidation reaction
Explanation:
Only one reaction happened and no reduction occurs.Hence, this the redox reaction does not happen.
Visible photon has more energy than a microwave photon. A microwave oven pumps out 1,000 watts of energy or more by generating a whole bunch of photons. Your conventional oven actually puts out even more energy (3,000 watts for an electric, 5,000 for gas). Most of that is infrared, which has less energy than visible light but more than a microwave.Thus the answer is <span>shorter than visible light.</span>
