If 209g of ethanol are used up in a combustion process, calculator the volume of oxygen used for the combustion at stp

SOVA2 [1]

Answer:

a) The volume of oxygen used for combustion at STP is approximately 305 dm³

b) The volume of gas released during combustion at STP is approximately 508 dm³

Explanation:

The given chemical reaction equation for the burning of ethanol in air, is presented as follows;

2CH₃CH₂OH (l) + 6O₂ (g) → 4CO₂ (g) + 6H₂O

The mass of ethanol used up in the combustion process, m = 209 g

The molar mass of ethanol, MM = 46.06844 g/mol∴

The number of moles of ethanol in the reaction, n = m/MM

∴ n = 209 g/(46.06844 g/mol) ≈ 4.537 moles

a) Given that 2 moles of ethanol, CH₃CH₂OH reacts with 6 moles of oxygen gas molecules, O₂, 4.54 moles of ethanol will react with (6/2) × 4.537 = 13.611 moles of oxygen

The volume occupied by one mole os gas at STP = 22.4 dm³

The volume occupied by the 13.611 moles of oxygen gas at STP, 'V', is given as follows;

V = 13.611 mol × 22.4 dm³/mole = 304.8864 dm³ ≈ 305 dm³

The volume occupied by the 13.611 moles of oxygen gas at STP, V = The volume of oxygen used for the combustion ≈ 305 dm³

b) The total number of moles of gases released in the reaction, is given as follows;

The total number of moles = (4.537/2) × (4 + 6) = 22.685 moles of gas

The total volume of gas released, $V_T$ = The volume of gas released during the combustion at STP = 22.685 moles × 22.4 dm³/mole = 508.144 dm³ ≈ 508 dm³

Prompt the user for a string that contains two strings separated by a comma. (1 pt)Examples of strings that can be accepted:Jill

Veronika [31]

Answer:

import java.util.Scanner;

public class ParseStrings {

public static void main(String[] args) {

/* Type your code here. */

Scanner sc= new Scanner(System.in);//to read inout from user

String sentence;//to hold user input

System.out.println("Enter input string");//asking user to input string reading into sentence

sentence=sc.nextLine();

while(!sentence.equals("q"))//continues untill user enters q

{

while(!sentence.contains(","))//loop ti eport error and continue till user enters valid string

{

System.out.println("No comma in string");

System.out.println("Enter input string");

sentence=sc.nextLine();

}

//extracting words from senetnece

String word1=sentence.substring(0, sentence.indexOf(',')).trim();

String word2=sentence.substring(sentence.indexOf(',')+1).trim();

System.out.println("First word:"+word1);

System.out.println("Second word:"+word2);

System.out.println("Enter input string");//asking user to input string reading into sentence

sentence=sc.nextLine();

}

return;

}

What framework provides a simple API for performing web tasks?

Kryger [21]

Answer:

Prototype is a framework that provides a simple API for performing web tasks.

Explanation:

Prototype is a JavaScript framework that aims to ease up the development of dynamic web applications. It basically take out the complexity out of the client-side programming.

Following are some salient features of Prototype:

1) Applies useful methods to extend DOM elements and built-in types.

2) Provides advance support for Event Management.

3) Provides powerful Ajax feature.

4) Built-in support for class-style OOP.

5) Not a complete application development framework

Need help with a program to search to sort elements in an array.(increasing or decreasing order)

astraxan [27]

This is for Python

numbers = [7, 3, 6, 9, 0]

print(numbers.sort())

Output: [0, 3, 6, 7, 9]

numbers = [7, 3, 6, 9, 0]

print(numbers.sort(reverse = True))

Output: [9, 7, 6, 3, 0]
