Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Which of the following steps correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine?
A. Divide 6 by the atomic mass of fluorine.
B. Divide the atomic mass of fluorine by 6.
C. Subtract 6 from the atomic mass of fluorine.
D. Multiply the atomic mass of fluorine by 6.
Answers
Answer:
A
Explanation:
mole=mass of the element ÷ atomic mass of the element.
mole=6÷atomic mass of flourine.
The step at A correctly converts 6 grams of fluorine to an equivalent number of moles of fluorine. That is "Divide 6 by the atomic mass of fluorine".
What is one mole of a substance?A mole is defined as the mass of the substance which consists of an equal quantity of basic units.One mole of any substance is equal to the value of 6.023 x \(10^2^3\) (Avagadro number). It can be used to measure the products obtained from the chemical reaction. The unit is denoted by mol.The formula for the number of moles formula is expressed as the number of moles of the substance = mass of the substance/ mass of one mole of the substanceHow to calculate the number of moles of fluorine equivalent to 6 grams of fluorine?Given that,
The mass of fluorine = 6 grams
The atomic mass of one mole of fluorine = 18.99
So, the number of moles of 6 grams of fluorine= \(\frac{6}{18.99}\)
Therefore, the step is given in option A: "Divide 6 by the atomic mass of fluorine" is the correct step that converts the 6 grams of fluorine to an equivalent number of moles of fluorine.

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answers
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.
Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.

O needs a mechanical pump
O is heated by hot rocks or magma
Please only give a ONE answer.
i said/asked calmly
Answers
The statement that describes an attribute of an artesian well is B. Uses natural pressure.
Artesian wells rely on natural pressure by accessing an underground water source that is enclosed between layers of impermeable rock or clay. The water within the aquifer is naturally pressurized due to the weight of the overlying rock or the slope of the land.
When a well is drilled into the aquifer, this existing pressure allows the water to rise to the surface without the need for a mechanical pump.
This utilization of natural pressure distinguishes artesian wells from other types of wells, as they do not require artificial pumping mechanisms to extract water.

2. Based off the answer to the first question, by hitting the ping pong ball, momentum is transferred from the boy to the ball. Causing the ball to have more velocity/speed and gain more momentum.
3. Momentum before = momentum after

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
