How much heat is released when 75 g of octane is burned completely if the enthalpy of combustion is -5,500 kJ/mol C8H18
AnnyKZ [126]
<span>Enthalpy change is the total heat that is absorbed or evolved in a certain reaction that is being carried in a constant pressure system. It can be calculated by the product of the specific heat of the substance and the difference of the final temperature and the initial temperature. For this case, the enthalpy of combustion is given, so we simply multiply the amount of octane present to the enthalpy given to determine the total heat that is released. 

Heat = 75 g ( 1 mol / 114.23 g ) (- 5500 kJ / mol ) = - 3611.14 kJ

The negative sign in the calculated value represents that this heat is being released in the process.</span>

A dextrose/saline aqueaout solution doctors commonly use to replace fluids in the body contains 1.75g/L NaCl and 40.0g/L dextros
qwelly [4]

<em>Mixed molarity = 0.25 M</em>

<em>Osmotic pressure solution: 6.15 atm</em>

<h3><em>Further explanation</em></h3>

Osmotic pressure is the minimum pressure given to the solution so that there is no osmotic displacement from a more dilute solution to a more concentrated solution.

General formula:

\large{\boxed {\bold {\pi \: = \: M \: x \: R \: x \: T}}}

π = osmotic pressure (atm)

M = solution concentration (mol / l)

R = constant = 0.08205 L atm mol-1 K-1

T = Temperature (Kelvin)

Mixing solution

To find the molarity of the mixed solution we can use the following formula:

Vc. Mc = V1.M1 + V2.M2

where

Mc =Mixed molarity

Vc = mixed volume

Mr. NaCl = 58.5

Mr. Dextrose = C₆H₁₂O₆ = 180

mole NaCl = gram / Mr

mole NaCl = 1.75 / 58.5 = 0.03

Dextrose mole = 40/180 = 0.22

Assuming 1 liter of solution

M mixture = mole NaCl + mole dextrose / 1 liter

M mixture = 0.03 + 0.22 / 1 L

M mix = 0.25 M

T = 25 + 273 = 298 K

The osmosis pressure of the solution becomes:

π = 0.25. 0.0825. 298 = 6.15 atm

Difference between Solute and solvet​
Olin [163]

Answer:

When one substance dissolves into another, a solution is formed. The solute is the substance that is being dissolved, while the solvent is the dissolving medium. Solutions can be formed with many different types and forms of solutes and solvents.

WHAT’S A NEW DISCOVERY THAT MAKES IT EASIER TO USE BIOMASS AS AN ENERGY SOURCE?​
balandron [24]
Biomass is a renewable source of fuel to produceenergy because: waste residues will always exist – in terms of scrap wood, mill residuals and forest resources; and. properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops.<span>
