The solubility of glucose at 30°c is 125 g/100 g water. A solution is made by adding 250 g of glucose to 100 ml of water at 30°c. Remember that 1 g water = 1 ml water. How would you classify this type of solution? heterogeneous saturated supersaturated unsaturated.
Answer:
C. Supersaturated
Explanation:
I know this is late but for others in the future who may need help.
Considering the definition of supersaturated solution, this type of solution is supersaturated.
Supersaturated solutionA solution is a supersaturated solution when it contains more solute than the amount supported under equilibrium conditions by the solvent at a given temperature.
In other words, supersaturated solutions are those in which more solute has been added than can be dissolved in the solvent. For this reason, it is observed that a part of the solute goes to the bottom of the container. That is, the observed solution is saturated (it contains the maximum amount of dissolved solute), and the excess settles at the bottom of the container.
This caseA solution is made by adding 250 g of glucose to 100 ml of water at 30°c. Remembering that 1 g water = 1 ml water, then a solution is made by adding 250 g of glucose to 100 g of water at 30°c.
The solubility of glucose at 30°c is 125 g/100 g water.
You can see that there is more solute than the solvent can incorporate (the solution can incorporate 125 g of glucose). Therefore the solution is supersaturated.

In (figure 1), what is the magnitude of the current in the wire above the junction?.
The magnitude of the current in the wire above the junction is;
5 A
Calculations using Kirchoff's Current Rule
From the image of the circuit attached, we see that;
For wire 1, current is flowing towards the junction and that;
Resistance; R₁ = 2Ω
Voltage; V₁ = 6V
For wire 2, current is flowing towards the junction and that;
Resistance; R₂ = 5 Ω
Voltage; V₂ = 10 V
Formula for current is;
I = V/R
Thus;
I₁ = V₁/R₁
I₁ = 6/2
I₁ = 3 A
I₂ = V₂/R₂
I₂ = 10/5
I₂ = 2 A
Now, kirchoff's current law or junction law states that the total current flowing into the junction is equal to the total current flowing out of the junction.
We see that the third wire which is above the junction has it's current flowing out of the junction. Thus;
I₁ + I₂ = I₃
3 + 2 = I₃
I₃ = 5 A

If a gas has a volume of 750 l at 298 k, what would the volume of the gas be at 328 k?.
Answer:
826 l
Explanation:
V1 = 750 l, T1 = 298 K
V2 = ?, T2 = 328 K
If the pressure is constant,
V1/T1 = V2/T2
so
V2 = V1 * (T2/T1) = 750 *(328/298) = 826 l

Isaac’s gross annual salary is $56,953. What is the maximum monthly rent he can afford? round to the nearest dollar.
The maximum monthly rent Isaac can afford is $1,329
What is gross salary?Gross salary is the total amount of money one receive annually.
We know that the maximum rent must be less than or equal to 28% of Gross Monthly Pay.
We will find out Isaac's Gross Monthly Pay by dividing Isaac's Gross Annual Pay by 12 (the number of months in a year)
= $56,953 / 12
= $4,746.08
Find out the maximum monthly rent he can afford
= 28%
= 28 / 100

Suppose a sugar cone is 10 centimeters deep and has a diameter of 4 centimeters. A spherical scoop of ice cream with a diameter of 4 centimeters rests on the top of the cone. (i) if all the ice cream melts into the cone, will the cone overflow? explain. (ii) if the cone does not overflow, what percent of the cone will be filled?.
Answer:
i)no as 42>33.5
ii)around 82 %
Explanation:
volume of the scoop - 4/3 pi r cube = ~33.5
volume of cone - 1/3 pi r square = ~42
Percent of cone will be filled is 81%
Volume base problem:Given that;
Length of sugar cone = 10cm
Diameter of sugar cone = 4 cm
Diameter of spherical scoop = 4 cm
Computation:
Diameter of sugar cone = 4 cm
Radius of sugar cone = 4/2 = 2 cm
Diameter of spherical scoop = 4 cm
Radius of spherical scoop = 4/2 = 2 cm
Volume of cone = [tex]\frac{1}{3}[\pi r^2h][/tex]
Volume of cone = [tex]\frac{1}{3}[(3.14) (2)^2(10)][/tex]

On a particular day, caroline decided to run two laps of a park of which each lap is 1. 2kms. She takes 12 minutes to run her first lap, and she runs her second lap at an average speed of 7 km/h. Determine her average speed over the two laps.
Answer:
6.46 km/h
Explanation:
Total distance d = 2 * 1.2 = 2.4 km
Total time t = 12 min + t' where t' is the time taken for second lap.
t' = 1.2 km/(7 km/h) = 1.2/7 hours
so t = 12/60 hours + 1.2/7 hours = 0.3714 hours
The average speed = d/t - 2.4/0.3714 = 6.46 km/h

In a multiple choice exam, there are 5 questions and 4 choices for each question (a, b, c, d). Nancy has not studied for the exam at all and decides to randomly guess the answers. What is the probability that:.
Using the binomial distribution, it is found that there is a 0.6836 = 68.36% probability that she guesses at least one right.
For each question, there are only two possible outcomes, either she gets it right or she does not get it right. The probability of getting a question right is independent of any other question, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are 5 questions, hence n = 5.For each question, she guesses one out of 4 options, hence p = 1/4 = 0.25.The probability that she guesses at least one right is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.25)^{0}.(0.75)^{4} = 0.3164[/tex]
Hence:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.3164 = 0.6836[/tex]
0.6836 = 68.36% probability that she guesses at least one right.
