Why is it essential for a calorimetry to be an insulated (closed) system?

Chemistry

aksik [14]2 years ago
5 0

Answer:

B.Thermal insulation minimizes energy loses to the atmosphere.

Explanation:

It is important because it helps to stop hit from transferring from the calorimeter to the environment. This would help to have an accurate measurement of the heat that was used in the chemical process. The greatest cause of error that happens in calorimetry is when heat is lost to the environment. To reduce this, you insulate the calorimeter and add a cover.

Leonard designed a parallel circuit to light two light bulbs. But his circuit doesn’t work. Which two items in the circuit must
klasskru [66]

Answer : When a parallel circuit is built the voltage across each of the components remains the same, also the total current passed is the equal to sum of the currents passing through each components in the circuits.


When 2 or more components are tried to be connected in parallel they maintain the same potential difference (in voltage) across their ends of the circuit.


The potential differences across the components are the observed to be same in magnitude, and they have identical polarities between them.


Then, this same voltage is applicable to all circuit components connected in parallel.


So, if each bulb is wired to the battery in a separate loop, the bulbs will be in parallel series.

What is the temperature of 1.2 moles of helium gas at 2.57 ATM if it occupies 15.5L of volume
agasfer [191]
We will assume helium to behave as an ideal gas and apply the ideal gas law:
PV = nRT
For pressure measured in atmospheres and volume measured in liters, the value of the molar gas constant is 0.082. Therefore:
T = PV / nR
T = (2.57 x 15.5) / (1.2 x 0.082)
T = 404.8 Kelvin

Summarize the five points of Dalton’s atomic theory, and explain at least one change that occurred to the atomic theory because
Umnica [9.8K]
The postulates of Dalton's theory were:
1) Elements are made of extremely small particles called atoms
2) <span>Atoms of a given element are identical in size, mass, and other properties
</span>3) <span>Atoms cannot be subdivided, created, or destroyed</span>
4) Atoms combine in whole number ratio to form compounds
5) Chemical reactions are the rearrangement of atoms
The third postulate has been disproved by modern science, in which the atom has been split and been subdivided into smaller parts such as the neutron, proton and electron, which are further subdivided into quarks, gluons, and kaons.
The second postulate was also disproved upon the discovery of isotopes.
