Answer:
A. 2.30 x 10^2 kil
Explanation:
3/2 = 1.5 and 0.72/2 = 0.36
1.93 + 0.36 = 2.29
2.29 = about 2.30

Answer:
They both describe atoms as being made up of positive and negative matter.
Explanation:
In both Bohr's model and Thomson model, the atom consists of positively-charged matter and negatively-charged matter. However, the structure of the atom in the two models is totally different:
- in Thomson's model, the atom consists of a large sphere of uniform positive charge, and electrons (which are negatively charged) are scattered all around inside this sphere
- In Bohr's model, the atom consists of a small, positively charged nucleus, while the electrons (negatively charged) orbit around the nucleus in precise orbits.
1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity
Answer:
A compound is a pure substance made of two or more elements chemically combined in a set ratio. ... If a different ratio of carbon atoms and oxygen atoms are seen in a formula, you have a different compound. For example, carbon monoxide—a gas produced in car engines—has the formula CO.
