A loose, icy body with a long, narrow orbit is a comet
Answer:
C
Explanation:
This experiment by Rutherford involved the firing of alpha particles at gold foils. It is also. called the gold foil experiment.
He fired these alpha particles at different points. He noticed that at some points, there were deflections, while at some other points, there were no deflections. It is necessary to state that these alpha particles are positively charged. For there to be a deflection, there must have been a kind of repulsion between the gold foil and the alpha particles.
From the basic physics of like repels like, he knew for sure that there must be dense positive core in the atom that is causing the deflection of the alpha particles. This enabled him to come up with the theory that the atom contained a small dense positive core called the nucleus
Answer:because it isnt flammable
Explanation:water can not be burned
Answer:
38825.472 M
Explanation:
Using
C1V1=C2V2
To make solution B,
C1 = 25.527 M, V1 = 13 mL
C2 = 25.527 x 8 = 204.216 M
V2 = 13 X 12 = 156 mL
To make solution C'
C1 = 8 X 202.216 M = 1617.728
V1 = 8 X 156mL = 1248 mL
V2 = 4 X 13 = 52 mL
C2 = C1V1 / V2
=1617.728 X 1248 / 52
=38825.472 M
The identity of a metal that has a mass of 27.0g and a volume of 10.0cm is Aluminium. That is option B.
<h3>What is molar mass?</h3>
Molar mass is defined as the mass in grams of one mole of an element. This is measured in grams/mole of that substance.
The metal that is 27.0 g and a volume of 10.0 cm3 is aluminium because aluminium is 27 times heavier than 1/12th of the mass of carbon-12 atom.
Therefore, the identity of a metal that has a mass of 27.0g and a volume of 10.0cm is Aluminium.
