Answer:
A compound is a pure substance that is composed of elements chemically bonded in definite proportions. A compound can be broken down into simpler substances only by chemical reactions, such as electrolysis. A solution is a homogeneous mixture, meaning that it is the same throughout.
Explanation:
.
Boyle's law gives the relationship between pressure and volume of gases.
it states that for a fixed amount of gas at constant temperature, pressure of gas is inversely proportional to volume.
PV = k
where P - pressure , V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting this equation
P x 0.5650 L = 715.1 bar x 1.204 L
P = 1 524 bar
Answer:
Using radiometric dating they SUPPORT the hypothesis on the origin of life on Earth
Explanation:
A fossil is a preserved remnant of a living organism from the past, this fossilization can be achieved by many processes including carbonization, recrystallization, permineralization, etc. These fossils can be used to obtain different information about the past and the origin of life on earth, for example,<em> chemical fossils are a kind of fossil found in rocks and fuels like coal or petroleum, they represent one of the oldest kind of fossils found and through the use of radiometric dating, where carbon isotopes are measured, their existence implies the presence of life as early as 4.1 billion years ago.</em>
I hope you find this information useful and interesting! Good luck!
