Mia is disappointed with how her latest video games are playing on her computer; the images are slow

Answer:

C3H8

Explanation:

Step 1:

Relevant details from the question are noted below:

Mass of the alkane is 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

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

Step 2:

Convert to the appropriate units.

For Volume:

1000mL = 1L

So, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature in Kelvin = Temperature in Celsius + 273

Temperature in Celsius = 28°C

Temperature in Kelvin = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

So, 741 mmHg = 741/760 = 0.975atm

Step 3:

Calculate the moles of the alkane.

The moles of the alkane can be found using the ideal gas equation, presented below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

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

Number of moles (n) =?

PV = nRT

n = PV /RT

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

n = 0.0266 moles

Step 4:

Calculate the alkane’s molar mass.

Mass of alkane = 1.17g

Number of moles = 0.0266moles

Molar Mass =?

Number of moles = Mass/Molar Mass

Molar Mass = Mass/Number of moles

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

Step 5:

Determine the molecular formula of the alkane.

This is based on:

The general formula for alkanes is CnH2n+2

To find the molecular formula, we start with n = 1, 2, 3, etc., until we find the 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

It can be observed that for n equal to 3, the molar mass is 44g/mol.

Thus, the molecular formula of the alkane is C3H8.

Answer:

def mph_and_minutes_to_miles(hours_traveled, miles_traveled):

   hours_traveled = minutes_traveled / 60

   miles_traveled = hours_traveled * miles_per_hour

   print('Miles: %f' % miles_traveled)

Explanation:

This function, written in Python, specifies two input parameters (hours_traveled, miles_traveled)

When executed, the main function prompts the user for necessary data, calls this method, and passes the inputs as arguments. Refer to the complete code and output that follows.

The correct answer to this query is "Hard drive." Explanation: Given the context of the inquiry, it's suggested that the most likely cause of this issue is the improper connection of the video cable. An incorrectly connected video cable can lead to display disruptions, such as the screen flashing black. While overheating of the GPU could also be a potential cause, it typically results in visual artifacts rather than shifting displays. Therefore, "Hard drive" is indeed the right answer.

Answer:

//This method takes a parameter called myString of type String

public static boolean isEmailAddress (String myString){

//verifying if the @ character exists in the string

if (myString.indexOf("@")!= -1) {

  //ensuring that only a single instance of @ appears in the string

   if (myString.indexOf("@") == myString.lastIndexOf("@")) {

   //confirming absence of space characters

  if (myString.indexOf(" ") == -1) {

    //checking for the absence of newline characters in the string

    if (myString.indexOf("\n") == -1) {

      //checking for absence of tab characters in the string

      if (myString.indexOf("\t") == -1) {

          return true;

      }

    }

  }

}

}

 return false;

}

Explanation:

The method takes a string presumed to be an email address and verifies whether it is valid, returning true if it is valid and false otherwise. The method checks the following conditions:

->The presence of the "@" character

->Only one occurrence of "@" exists in the string

->No spaces present

->No newline characters present

->No tab characters present

Returning true only if all these conditions are met.
