D is the correct answer hope this helps
Answer:
Monosaccharides!
Explanation:
monosaccharies are the building blocks of all carbohydrates! Starch and glycogen are carbs that consist of multiple monos.
Answer:
Explanation:
Hello,
In this case, it is firstly necessary to compute the dissolved moles of hydrogen chloride into the water as shown below:
Thus, the molarity is computed as shown below:
Wherein no change in volume is considered, therefore the volume of the solution was the same volume of water.
Best regards.
Answer:
The number of moles of X2(g) present at equilibrium is 0.0981.
Explanation:
Being:
aA + bB ⇔ cC + dD
the reaction constant Kc is defined as:
That is, the constant Kc is equal to the multiplication of the concentrations of the products raised to their stoichiometric coefficients by the multiplication of the concentrations of the reactants also raised to their stoichiometric coefficients.
Being the balanced reaction:
H₂(g) + X₂(g) ⇔ 2 HX (g)
the constant Kc is:
In this case, Kc = 24.4 and being :
Replacing in the definition of the constant of Kc:
Solving:
[X₂]= 0.0327
Applying the definition of concentration , and the volume being 3 liters:
Solving:
number of moles of X₂= 0.0327* 3 liters
number of moles of X₂= 0.0981
<u><em>The number of moles of X2(g) present at equilibrium is 0.0981.</em></u>
Due to its higher oxygen content and based on its structure dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
<h3>What is the calorific value of a fuel?</h3>
The calorific value of a fuel is the amount of heat energy released from the combustion of the fuel under standard conditions.
Dietheylene glycol, isopropanol and paraffin wax are all used as fuels.
However, due to it higher oxygen content and based on its structure, diethethylene glycol has a higher calorific value than either isopropanol or paraffin wax.
Therefore, dietheylene glycol has a higher energy efficiency (cal/g) compared to isopropanol and paraffin wax.
