The circumstance which is it appropriate to ignore a data point when drawing the best line through data to make a graph is when there is the presence of the outliers.

<h3>What is a Graph?</h3>

This is defined as the pictorial representation of data or variables in an organized manner.

The graph when plotted contain a lot of points in which a line is drawn to pass the majority of them. In situations whereby some of the data point don't follow the line drawn then it must be ignored.

This is because they don't usually reflect the trend of the data which is why this particular scenario was chosen as the most appropriate choice.

What object is being acted on by balanced forces?
tamaranim1 [39]

Answer: D . A car that moves at a constant speed in one direction.

Explanation: D is the answer because a car moving in a constant speed represents a balance force because the speed is constant and the forces are balanced or , when a car travels at a constant speed, the driving force from the engine is balanced by resistive forces such as air resistance and friction in the car's moving parts.

8. If 0.795 moles of ammonia gas occupies 42.5 L at 670 torr, what is the Celsius temperature?
maksim [4K]

<u>Answer:</u> The temperature in degree Celsius is 301.31°C

<u>Explanation:</u>

To calculate the temperature, we use the equation given by ideal gas, which is:

PV=nRT

P = pressure of the gas = 670 torr = 0.882 atm   (Conversion factor: 1 atm = 760 torr)

V = volume of gas = 42.5 L

n = number of moles of gas = 0.795 mol

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of gas

Putting values in above equation, we get:

0.882atm\times 42.5L=0.795mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times T\\\\T=574.31K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

574.31=T(^oC)+273\\T(^oC)=301.31^oC

Hence, the temperature in degree Celsius is 301.31°C

87 g of oxygen gas would occupy how many liters of volume at stp
loris [4]
Number of mole : mass/ molar mass

87g/ (2 x 16) = 2.719 mol

volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L
