Please Help! 100 Points! Look at the two thermometers.
Which statement explains which thermometer is more appropriate to measure the temperature of a liquid at 47 °C?

Thermometer C, because it measures accurately to the tens place.
Thermometer D, because it measures accurately to the tens place.
Thermometer C, because it measures accurately to the ones place.
Thermometer D, because it measures accurately to the ones place.

A

Explanation:

Accuracy : It is defined as the closeness of a measured value to a standard or known value.

For Example : If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by first person is more accurate.

Precision : It is defined as the closeness of two or more measurements to each other.

For Example : If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.

The level of precision is determined by the maximum number of decimal places.

As we are given that the measurement of the temperature of a liquid at .

From the given thermometer we conclude that, the thermometer A is more appropriate than the thermometer B because in thermometer A there are 10 divisions between the two temperature and the smallest division is, 0.1.

So, the temperature of liquid will be,

So, the temperature of liquid will be,

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
