How will you describe the difference between heat and temperature?

Graphing is an important procedure used by scientist to display the data that is collected during a controlled experiment. There

astraxan [27]

Bar graph or bar chart displays data graphically using bars

The correct values are;

1. The independent variable is the month of the year

2. The dependent variable is the number of deer

3. The title is: The number of deer counted per month

The reason the above values are correct are as follows:

In a tabular form is given as follows;

$\begin{array}{|c|cc|}Month&&\# \ of \ deer \\Sept&&38\\Oct&&32\\Nov&&26\\Dec&&20\\ Jan &&15\\Feb&&12\end{array}\right]$

A. Please find attached the required bar graph (chart) created with a desktop application

1. In an investigation to assign the cause of an effect is the cause of an effect, the independent variable is the causal variable responsible for the observed effect, and it is not affected by the effect. It is the variable that is not measured

In the given data, the month of the year is not affected by the number of deer, and it is not counted, to see if there is a change, therefore, the independent variable is the month of the year

2. The dependent variable, is the effect variable that is measured, and it depends on the dependent variable, which is the month

Therefore, the dependent variable is the number of deer

3. An appropriate title is one that captures the information intended to be obtained from the Bar graph

An appropriate title for the bar graph is; The number of deer counted per month

Read the chemical equation.

Sladkaya [172]

Answer:- D. 1.8 moles of Fe and $2.7molCO_2$ .

Solution:- The balanced equation is:

$Fe_2O_3+3CO\rightarrow 2Fe+3CO_2$

let's first figure out the limiting reactant using the given moles and mol ratio:

$1.8molFe_2O_3(\frac{3molCO}{1molFe_2O_3})$

= 5.4 mol CO

From calculations, 5.4 moles of CO are required to react completely with 1.8 moles of Iron(III)oxide but only 2.7 moles of CO are available. It means CO is limiting reactant.

Products moles depends on limiting reactant. Let's calculate the moles of each reactant formed for given 2.7 moles of CO.

$2.7molCO(\frac{2molFe}{3molCO})$

= 1.8 mol Fe

$2.7molCO(\frac{3molCO_2}{3molCO})$

= $2.7molCO_2$

So, the correct choice is D. 1.8 moles of Fe and $2.7molCO_2$ are formed.

A 35 L tank of oxygen is at 315 K with an internal pressure of 190 atmospheres. How

nata0808 [166]

Answer:

600.7 moles

Explanation:

Applying,

PV = nRT................... Equation 1

Where P = Pressure of oxygen, V = Volume of oxygen, n = number of moles, R = molar gas constant, T = Temperature.

make n the subject of the equation

n = PV/RT............... Equation 2

From the question,

Given: P = 190 atm, V = 35 L, T = 135 K

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

n = (190×35)/(135×0.082)

n = 600.7 moles of xygen
