Liquids Characteristics,<span> Liquid metal flows to fill the mold. As it cools, it solidifies. Once it is cool enough, it can be removed from the mold as a solid. The ability to flow is one characteristic that is different in solids than liquids. </span>
The answer is D hope this helps
Explanation:
An isotope is defined as the specie which contains same number of protons but different number of neutrons.
For example, and are isotopes.
In a neutral carbon atom, there are 6 protons and 6 neutrons.
As it is known that in a neutral atom the number of protons equal to the number of electrons.
This means that in a neutral carbon atom there are also 6 electrons.
Whereas is an isotope of carbon atom whose atomic number is 6 and atomic mass is 13.
Hence, calculate the number of neutrons in as follows.
Atomic mass = no. of protons + no. of neutrons
13 = 6 + no. of neutrons
no. of neutrons = 13 - 6
= 7
Hence, in a isotope of carbon atom there are 6 protons, 6 electrons and 7 neutrons.
This shows that change in number of neutrons take place according to the definition of an isotope.
Answer:
1.693 atm
Explanation:
According to Boyle's Law, an inverse relationship exists between pressure and volume. ... The relationship for Boyle's Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change under a constant temperature and ideal behaviour
P1V1 = P2V2
P1 = 5.08
V1= 1.19L
P2=?
V2= 3.57L
P1V1 = P2V2
5.08x 1.19 = P2(3.57L)
6.0452/3.57 = P2 = 1.693 atm
I think it’s going to be 8, which is my best guess. Good luck
