which solute will result in a molecular solution?
a. HCN
b. Ba(OH)2
c. CH3COOH
d. CH3CH2OH
Answers
Answer:
d. CH3CH2OH
Explanation:
Molecular solution are solutions when a molecular compound is dissolved in them.
CH3CH2OH represents Ethanol or alcohol carrying "OH" group and is a molecule. CH3CH2OH or Ethanol forms a molecular solution in water.
The equation for Ethanol dissolving in water as follows:
CH3CH2OH(l) => CH3CH2OH(aq)
CH3CH2OH srays together as molecules. During dissolving, ethanol molecule fit into spaces between water molecules and completely mix with water.
While HCN, CH3COOH and Ba(OH)2 form ionic solution.
Hence, the correct option is d. CH3CH2OH.

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.

You have a board, wood blocks, and a toy car. Your goal is to build a ramp that sends the car as far across the floor as possible. What angle between the board and floor would be best? Explain your answer
Answers
Answer:
The board should be placed at about an 80-88 degrees angle.Explanation:
This will speed the car up and increase its speed as going down the ramp.
Potential and Kinetic Energy
Set up a basic ramp against a chair, on top of some books, or from a table to the floor. Hold the car at the top of the ramp, and release to demonstrate the two main kinds of energy. Potential energy is placed into the car when it's lifted from the floor, and that energy is released as the car rolls down the ramp. Ramps should be made of a solid, smooth and rigid material such as wood or plywood.
Friction
Using the ramp from earlier, you can make a more interesting experiment by placing some things at the bottom. Drop the car from the top of the ramp again, and measure how far it rolls this time. Now, place a sheet of cardstock at the bottom of the ramp, and let the car roll over that. Measure the distance it rolls. Place some sandpaper on top of the card stock, release the car, and measure that distance. Finally, try it with some carpet at the bottom. You've now learned something about friction: the card stock has a lot less friction than the carpet, so the car should be able to roll farther.
Inertia
Place a heavy stack of books a few feet from the end of the ramp, so that the car hits those books when it rolls from the top down. Demonstrate that once or twice, and then take a small ball of clay or putty. Place it on top of the car and pat it down slightly; don't squish it onto the car, but press it just enough so that it won't roll off. Roll the car down the ramp, and when it hits the books, the clay should fly off the front of the car. This happens because of Newton's first law of motion: anything moving is going to want to keep moving (until it crashes into a wall).
Angle
The optimal angle for the board is about 80⁰

Answer:
A. Palms and other small trees
Explanation:
Understory Layer
Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.

Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answers
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

Answers
Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .
Explanation:
Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .
Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

A student uses red litmus paper to test the pH value of different solutions. Which would result in a color change of the litmus paper?
soap
vinegar
lemon juice
antifreeze
Answers
The litmus paper shows red colour for acidic substances and blue colour for basic substances. Thus a red litmus paper will turn blue if it is dipped in an alkaline solution. Soap is alkaline and given blue color to litmus.
What is pH?pH of a substance is its measure of concentration of H+ ions in it. It is mathematically negative logarithm of H+ ion concentration. Thus, pH measures how much acidic or basic the solution is.
A pH of of 7 is neutral having no acidity or basicity. A pH less than 7 is acidic and pH greater than 7 is basic in nature. Vinegar is acetic acid and it shows less pH . Lemon juice also acidic since it contain citric acid whereas, soap is basic.
A litmus paper is used to identify whether a substance is acidic or basic. It shows red color for acidic solutions and blue for basic solutions. If the red litmus paper is dipped in acidic one, it shows no colour change if it is dipped in basic solution then it turns to blue.
Soap is highly alkaline and it changes red litmus paper to blue.
