You observe your friend rub a balloon on their wool sweater and then stick it to the wall. To investigate, you set up an experiment to test whether other objects will respond in the same way when you rub them against a sweater. What is the test variable in your experiment?
A. The number of times you rubbed the object on the sweater
B. The observation that the object sticks to the wall
C. The sweater you use to rub against the objects
D. The type of objects you are testing in the experiment
Answer:
D
Explanation:
BEcause you are testing which objects will stick. Your control variable will be the sweater. And the number of times you rub the object on the sweter will not make it stick. It will make it stick for a longer period.
Answer:
D. The type of objects you are testing in the experiment
Compound Y dissolves in ethanol but not water what type of bond is Y ?
Covalent Bond.
Explanation: Covalent compound are soluble in organic solvents (non polar) but insoluble in water (polar).
Ethanol being both polar and non polar can dissolve covalent compound.
Find the percent by mass concentration if the solution was prepared by dissolving 25.0 g of sugar into 100 g of water.
Answer:
25%
Explanation:
Percent by mass is looking at the percentage of mass within a a solution. So since there's 100g of water and 25 grams of sugar, you divide 25 by 100 to get the ratio. Then multiply by 100 to get the percentage.
Imagine you are an astronaut and you travel to a planet with a much larger mass than Earth. How would this affect your weight? Explain your answer. (4 points)
Answer:
Explanation:
It may not make any difference. The information missing is the radius of the planet.
However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..
The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase. The question is done by a proportion.

Determine the pH of 7.53 x 10-4 mol/L calcium hydroxide solution
Answer:
pH = 11,17
Explanation:
[tex][OH^{-} ] = \frac{n_{OH^{-} } }{V} = \frac{2n_{Ca(OH)_{2} } }{V} = 2[ Ca(OH)_{2} ]\\[/tex]
[tex]Ca(OH)_{2}[/tex] → [tex]Ca^ {2+}[/tex] + [tex]2OH ^ -[/tex]
[tex]7,53.10^-4[/tex] → [tex]7,53.10^-4[/tex] → [tex]1,506^-3[/tex]
pOH = -log [[tex]OH^-[/tex]] = [tex]-log 1,506^{-3}[/tex] ≈ 2,822
pH = 14- pOH = 14-2,822 = 11,178
What is moisture in the atmosphere

Short definition of inclined plane
Answer:
inclined plane, a simple machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the incline is less than the weight being raised, discounting friction
Explanation:
The steeper the slope, or incline, the more nearly the required force approaches the actual weight. The steeper the slope, or incline, the more nearly the required force approaches the actual weight.

when does cells breakdown a sugar molecule completely to produce chemical energy ATP the cells need to the following materials
Answer:
sugar and carbon dioxide
Explanation:
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation. Cellular respiration requires oxygen, but fermenta- tion does not.

What is the change in oxidation number of bromine in the following re-dox reaction Cl 2 +2HBr 2HCl+Br 2 A -2;0 B) -1;0 C) 0: -1 D) 0;-2
Answer:
ANSWER
ANSWER: +1
EXPLANATION
What is the change in oxidation number of bromine in the following re-dox reaction Cl 2 +2HBr 2HCl+Br 2 A -2;0 B) -1;0 C) 0: -1 D) 0;-2
for Cl 2 +2HBr 2HCl+Br 2 , the Cl in Cl2 is reduced from "0" to
"-1" and the Br in HBr is oxidized from "-1" to "0"
So the change in oxidation number is +1
If a 22.4 L volume of a sample of gas has a density of 0.900 grams/L at 1.00 atm and 0.00°C. Given
the following gases, which could it be?
A. Ne
B. CO
C. CO2
D. Kr
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
How do the atoms aluminum and fluorine react to form the compound aluminum fluoride?
Answer:
Aluminum fluoride is an ionic compound. Meaning that the two elements form a ionic bond. In ionic bonding, atoms receive and donate electrons in order to become stable. In this case, aluminum donates its three outer electrons to three fluorine atoms. Aluminum forms a triple positive aluminium ion (Becomes a cation) and fluorine forms three single negative fluoride ions (Becomes a anion).
Aluminum (3+)Fluorine (1-)what is the differece between substance and matter?
Answer:
Anything that occupies space and has mass is matter but the matter that has specific composition and chemical characteristics is substance
Answer:
Substance: Something that has only 1 atom, for example; Water.
Matter: Made up of more than 1 atom, example; Humans
Explanation:
As said a substance is something that has only 1 atom like water or tin.
Matter is well almost everything in the universe, there's a reason some people say; This is Human Matter. I'm pretty sure it's somewhere in the bible too.

Which of the following are elements? (Select all that apply.)
KCl
Na
C
H2O
Answer:
Na(Sodium) and C(Carbon) only
Answer:
Na, C
Explanation:
1. KCl, or potassium chloride, is a combination of two elements- so it's a chemical compound.
2. Na, or sodium, can be found on the periodic table of elements. Therefore, it is an element.
3. C, or carbon, can also be found on the periodic table of elements. Therefore, it is an element.
4. H20, or water, is a combination of 2 hydrogen atoms that bonded into an oxygen atom. Combination of 2 or more elements is a chemical compound.
Therefore, the answers are Na and C.
2. Which of the following statements is true about covalent bonding?
A It is the attraction of atoms for an electron
B it involves the losing and gaining of electrons
Cit involves the sharing of electrons
Dit involves the moving of electrons between energy levels
Answer:
C. it involves the sharing of electrons
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Elements in the same period in the same periodic table have the same ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

Why must you continue to increase the temperature as you perform distillation ?
Answer:
It is possible to separate several distinct compounds according to their varying volatilities by altering the temperature of the distillation process. A nonvolatile solute, on the other hand, will always remain in the solution if you have a nonvolatile solute in your solution.
Explanation:
Hope it helps:)
Answer:
The reason for this is that the composition of the vapor that is distilling varies continuously during the distillation
