Answer:

Cranberry Juice is a Homogeneous Solution.

Explanation:

A Homogeneous solution is identifiable as a solution that looks like it is one single fluid.

A heterogeneous solution would be categorized as a solution that is obviously two different compounds, like oil and water.

A colloid is similar to the way a homogeneous solution is identified, however, colloids have particles suspended in them that are 1 nanometer to 1 micrometer in length (If particles are smaller than 1 nanometer it is considered a homogeneous solution). Colloids can be identified by shining a flashlight into them. If the beam disperses, it's a colloid. If it goes straight through without dispersing, it's a homogeneous solution. A colloid example is Milk.

A Suspension is similar to a colloid, however, the particles in a suspension are larger than 1 micrometer. Particles in a suspension can often be seen with the naked eye, whereas Colloid particles cannot. A suspension's particles will often separate from the base solution in time. A suspension example would be shaking glitter up in a bottle of water.

Why pie bond are not perticipate in hybridaization​
DedPeter [7]
The first bond between two atoms is always a sigma bond and the other bonds are always pi bonds and a hybridized orbital cannot be involved in a pi bond. Thus we need to leave one electron (in case of Carbon double bond) to let the Carbon have the second bond as a pi bond.

what is the concentration of hydroxide ions after 50.0 ml of 0.250 m naoh is added to 120 ml of 0.200 m na2so4? please show all
Galina-37 [17]

The concentration of the hydroxide ions after 50 ml of 0.250M NaOH is added to 120ml of 0.200M Na2SO4 is 7.35 x 10^-2 M.

What is meant by concentration?

Concentration is the total amount of solute present in the given volume of solution. this is expressed in terms of molarity, molality, mole fraction, normality etc. The term concentration mostly refers to the solvents and solutes present in the solution.

Concentration of hydroxide ions can be calculated by,

M (OH^-) = V (NaOH) x M (NaOH) / V (total) = 50ml x 0.250M / 50ml + 120ml = 0.0735M = 7.35 x 10^-2 M.

where M (OH^-) = concentration of hydroxide ions, V(NaOH) = volume of NaOH, M(NaOH) = concentration of NaOH.

Therefore, the concentration of the hydroxide ions after 50 ml of 0.250M NaOH is added to 120ml of 0.200M Na2SO4 is 7.35 x 10^-2 M.

Why bromine is a ring deactivator as it is ortho-Para directing group??
Anettt [7]

Answer:

here you go

Explanation:

Halogens are very electronegative. This means that inductively they are electron withdrawing. However, because of their ability to donate a lone pair of electrons in resonance forms, they are activators and ortho/para directing. Electron withdrawing groups are meta directors and they are deactivators.

Calculate the concentration in mol/L, M, of an aqueous sugar solution with a concentration of 23.5% (w/w) and density of 1.005 g
Temka [501]

Answer:

The concentration in mol/L is 0.683M

Explanation:

23.5% (w/w)

This data means that in 100 g of solution, we have 23.5 grams of solute.

From this point, we can calculate the moles of sugar.

Moles = Mass / Molar mass

Moles = 23.5 g /342.30 g/m

Moles = 0.068 moles

Density data make us know, the volume of our solution.

solution δ = solution mass / solution volume

δ = 1.005 g/mL = 100 g /  solution volume

solution volume = 100g / 1.005 g/ml

solution volume = 99.5 mL

In conclusion, 0.068 moles are in 99.5 mL

Molarity (M) is mol/L

Let's convert 99.5 mL in L

99.5 mL / 1000 = 0.0995 L

0.068 m / 0.0995L = 0.683

<em>If we convert moles in mmoles, we can also get Molarity (M)</em>

<em>mmoles / mL = M</em>

<em>0.068 moles . 1000 = 68 mmoles</em>

<em>68 mmmoles / 99.5mL = 0.683</em>

Which substances corrode copper?​
DiKsa [7]
The presence of oxidizing acids; heavy-metal salts, sulfur, and ammonia; and a number of sulfur and ammonia compounds can cause corrosion to set in. Water that comes from a well is much more likely to contain these materials and put copper lines in jeopardy—but it can occur in the civic water system as well.

Copper corrodes at insignificant rates when used in areas with unpolluted air, non-oxidizing acids, and water. However, it happens more rapidly with the presence of road salt, ammonia, sulfur, oxidizing acids

Acidic substances react with the surface of copper, causing it to tarnish and corrode almost instantly. This corrosion is highly soluble, leading to the presence of toxic copper salts in the food. This is why it is not recommended to use copper vessels for foods high in acidity, such as milk, wine, or vinegar.
