Hello!
I'm going to have to infer that you meant "grams" and not "gallons" :-)
Anyways, to find the density, you need to the divide mass over volume (d = m/V).
Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.
40.5 grams / 15.0 mL = 2.7 g/mL
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
Answer:
rising pressure and decreasing temperature
Explanation:
Reversible reactions have a bit practical interest, but in some cases the technological benefit or profitability of production requires a shift in the equilibrium of a reversible reaction.
Increasing pressure
With increasing pressure on this system, the concentration of substances increases. In this case, the balance will shift towards smaller volumes. On the left side of the equation, two volumes of nitrogen react with one volume of hydrogen. On the right side of the equation there are two volumes of ammonia, i.e. the number of volumes on the right side of the equilibrium reaction is less than on the left and, therefore, with increasing pressure, the reaction equilibrium will shift to the right.
Decreasing temperature
When the temperature rises, the equilibrium shifts towards the endothermic reaction, and when the temperature decreases, towards the exothermic reaction and the reaction given above is the exothermic.
Explanation:
(a) a functional group is a special group of atoms or bonds in a compound that is responsible for the chemical reactions, behavior, and characteristics of that compound. (b) Functional group is present in both the compound is alcohol (-OH).
Functional groups are specific groupings of atoms within molecules that have their own characteristic properties, regardless of the other atoms present in a molecule. Common examples are alcohols, amines, carboxylic acids, ketones, and ethers.
Key Points
Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it would have in its original form.
Functional groups will undergo the same type of reactions regardless of the compound of which they are a part; however, the presence of certain functional groups within close proximity can limit reactivity.
Functional groups can be used to distinguish similar compounds from each other.
Key Terms
functional group: A specific grouping of elements that is characteristic of a class of compounds, and determines some properties and reactions of that class.
functionalization: Addition of specific functional groups to afford the compound new, desirable properties.
I would actualy label it or put a little diagram below to show what part it is
