The minerals in hard water react with soap and affect its cleaning capacity. It's still possible to use hard water when washing by using more soap. The additional soap will no longer be affected by the minerals in the water, so they can clean just as effectively, but you'll be wasting more soap this way.

Chlorine consists of two isotopes with masses of 35 and 37. If the average atomic mass of a sample of chlorine atoms is 35.5, wh
Elza [17]

Answer:

The ratio 35Cl/37Cl =  3/1

Explanation:

<u>Step 1:</u> Data given

Chlorine has 2 isotopes:

- mass = 35 g/mol

- mass = 37 g/mol

Average molar mass of chlorine = 35.5 grams

<u>Step 2: </u>Calculate the % of isotopes

35x + 37y = 35.5

x+y = 1 or x = 1-y

35(1-y) + 37y = 35.5

35-35y +37y = 35.5

0.5 = 2y

y = 0.25 = 37Cl

x = 1 - 0.25 = 0.75 = 35Cl

<u>Step 3: </u>

The ratio 35Cl/37Cl = 0.75/0.25 = 3/1

Identify each of the following mixtures as either homogeneous or heterogeneous and as a solution, a suspension, or a colloid.
Sergeeva-Olga [200]

Blood.

<span>Blood is heterogeneous because it has corpuscles (blood cells and platelets) physically suspended in blood plasma.   Blood plasma and the corpuscles have different properties and can be separated by methods such as centrifugation. Also, blood is considered a colloid suspension because it has the properties of both a colloid and a suspension. This is because the blood plasma acts as a colloid. More so, if blood was left to settle,then the blood cells would collect at the bottom hence taking the characteristic of a suspension. </span>

<span>Salad dressing.</span>

<span>Depending on the type of salad, it can either be a heterogeneous or homogeneous mixture. If the salad dressing is only of vinegar or any other oil, then it is a homogenous mixture. However, if it involves a mixture of vinegar and other oils, pepper, herbs, and etcetera, then it is a heterogeneous mixture</span>

The white tern is a seabird that catches fish by plunging into the water. What physical features of the bird likely make this fe
V125BC [204]

White tern catches fish including crustaceans, flying fish, squid, and others. Prior of plunging into water, it hovers initially over the water surface and then either dives or dips in the surface, without getting entirely submerged into water, and catches its target.  

The food or fish is captivated in its small, however, sharp black beak that is specific as it bent upwards and tapers to a sharp point. It also possesses a long slender body with tapering, long wings, all of which encourage its diving or dipping activity into the surface of the water.

This graph represents a population of molecules in a gas versus the distribution of the average velocity(speed) of its molecules
pshichka [43]

Answer:

Part A

Given that the graph is symmetrical and bell shaped, the average kinetic energy is given by the midline of graph, which corresponds to the common speed of the highest number of the population

Part B

The formula for the average kinetic energy, K.E. = (3/2)·(R/NA)·T

Therefore, the part of the graph that indicates the temperature of the sample is the average kinetic energy. K.E.

Part C

At a lower temperature, the heat is less evenly distributed and we have the distribution T2 higher than T1
