Input device is a term used to explain <em>computer hardware that a user can utilize to provide the data that she or he wishes to put into the computers. </em>

From all the available options, the best answer to the first blank space would be keyboard, because keyboard is an input device you use to insert alphanumerical data into your computer. Based on this, the answer to the second blank space would be entering data.

A 1.17 g sample of an alkane hydrocarbon gas occupies a volume of 674 mL at 28°C and 741 mmHg. Alkanes are known to have the gen

Nina [5.8K]

Answer:

C3H8

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Mass of alkane = 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

Gas constant (R) = 0.08206 atm.L/Kmol

Step 2:

Conversion to appropriate unit.

For Volume:

1000mL = 1L

Therefore, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature (Kelvin) = Temperature (celsius) + 273

Temperature (celsius) = 28°C

Temperature (Kelvin) = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

Therefore, 741 mmHg = 741/760 = 0.975atm

Step 3:

Determination of the number of mole of the alkane..

The number of mole of the alkane can be obtained by using the ideal gas equation. This is illustrated below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

Gas constant (R) = 0.08206 atm.L/Kmol

Number of mole (n) =?

PV = nRT

n = PV /RT

n = (0.975 x 0.674)/(0.08206x301)

n = 0.0266 mole

Step 4:

Determination of the molar mass of the alkane.

Mass of alkane = 1.17g

Number of mole of the alkane = 0.0266mole

Molar Mass of the alkane =?

Number of mole = Mass/Molar Mass

Molar Mass = Mass/number of mole

Molar Mass of the alkane = 1.17/0.0266 = 44g/mol

Step 5:

Determination of the molecular formula of the alkane.

This is illustrated below:

The general formula for the alkane is CnH2n+2

To obtain the molecular formula for the alkane we shall assume n = 1, 2, 3 or more till we arrive at molar Mass of 44.

When n = 1

CnH2n+2 = CH4 = 12 + (4x1) = 16g/mol

When n = 2

CnH2n+2 = C2H6 = (12x2) + (6x1) = 30g/mol

When n = 3

CnH2n+2 = C3H8 = (12x3) + (8x1) = 44g/mol

We can see that when n is 3, the molar mass is 44g/mol.

Therefore, the molecular formula for the alkane is C3H8.

Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two

qaws [65]

Answer:

Se explaination

Explanation:

/Declaring variables

integer currentPrice

integer lastMonthPrice

integer changeLastMonth

float mortagage

//Reading input

currentPrice = Get next input

lastMonthPrice = Get next input

//Calculating price change

changeLastMonth = currentPrice - lastMonthPrice

//Calculating mortagage

mortagage = (currentPrice * 0.051) / 12

//Printing output

Put "This house is $" to output

Put currentPrice to output

Put "\nThe change is $" to output

Put changeLastMonth to output

Put " since last month." to output

Put "\nThe estimated monthly mortgage is $" to output

Put mortagage to output

Select the correct navigational path to freeze the top row of your worksheet. Select the panes you wish to freeze. Click the tab

Artemon [7]

Yeah, Your steps ar correct. Let's analyse those steps more easily by the following steps:

$\Large{ \boxed{ \bf{ \color{aqua}{Freeze \: panes:}}}}$

Freeze panes is a feature in spreadsheet applications, such as Microsoft Excel, LibreOffice Calc, and Google Sheets. It "freezes" a row or column, so that it is always displayed, even as you navigate the spreadsheet.

❍ Freezing panes is especially useful if your spreadsheet has a header row, that you want to always be visible.

Select the row below the row(s) you want to freeze. In our example, we want to freeze rows 1 and 2, so we'll select row.
Click the View tab on the Ribbon.
Select the Freeze Panes command, then choose Freeze
Panes from the drop-down menu. ...
The rows will be frozen in place, as indicated by the gray line.
