For waves:
speed = frequency x wavelength
speed = 3 x 10⁸
frequency = 9192631770 Hz
wavelength = 3 x 10⁸ / (9192631770)
wavelength = 0.033 meters
This wavelength lies in the region of microwaves.
Answer:
Sublimate
Explanation:
The solid obtained at the neck of a funnel in sublimation is called the sublimate.
This substance is a solid.
- Sublimation process is a phase change.
- In this process, a solid is directly changed to gas or gas changed to solid.
- Heat must be added to change the solid to gas and heat removed for the reverse process.
- Not all substances have this capability.
Atomic Number. (Or the number of protons in that element, same thing)
Answer:
it's atomic number reveals it's amount of electrons, each shell have a certain amount it could carry it's
2-8-8-18-18-32-32
It's called the octet rule.
Answer:
Option A. Double Replacement
Explanation:
A double displacement reaction is a kind of reaction in which there is an exchange of the ions of the two reactants to form a different products. In the equation, K in KOH displaces H in H3PO4 to form K3PO4 and also, the H combines with OH to form water.
H3PO4+3KOH -> K3PO4+3H20
