Which one if the following are appropriate units for measuring volume

1 answer:

5 0

Volume is expressed in "cubic" as prefix of the material being measured.

In cement, it would be measured in cubic yards 
In liquids in can be liters, gallons, ounces etc.. 
That's my answer off the top.... 
Norm 

In SI, you use litres and derivatives (such as ml, kl, etc.) 
In Imperial and US, the units are ounces, cups, pints, quarts, and gallons.

Which of the following reactions below could be properly categorized as a synthesis reaction?

kari74 [83]

Answer:

A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic. An example of a synthesis reaction is the formation of water from hydrogen and oxygen.

A piece of metal with a mass of 159 g is placed in a 50 mL graduated cylinder. The water level rises from 20. mL to 41 mL. What

almond37 [142]

Volume of water displaced is equal to the volume of the metal. So 41 - 20 = 21 ml. Density = mass / volume so density = 159 / 21 = 7.57 g/ml

What is the free energy change if the ratio of the concentrations of the products to the concentrations of the reactants is 22.3

snow_lady [41]

The free energy change(Gibbs free energy-ΔG)=-8.698 kJ/mol

<h3>Further explanation</h3>

Given

Ratio of the concentrations of the products to the concentrations of the reactants is 22.3

Temperature = 37 C = 310 K

ΔG°=-16.7 kJ/mol

Required

the free energy change

Solution

Ratio of the concentration : equilbrium constant = K = 22.3

We can use Gibbs free energy :

ΔG = ΔG°+ RT ln K

R=8.314 .10⁻³ kJ/mol K

$\tt \Delta G=-16.7~kJ/mol+8.314.10^{-3}\times 310\times ln~22.3\\\\\Delta G=-8.698~kJ/mol$
