Luciana explains to Eric how electricity flows in a circuit. Which sentences are a part of her explanation? Select all that apply.
A. Without a resistor, electricity cannot flow in a circuit.
B. Without a switch, electricity cannot flow in a circuit.
C. For electricity to flow in a circuit, the circuit must be complete.
D. An insulator such as plastic is needed for electricity to flow in a circuit.
E. A conductor is needed for electricity to flow in a circuit.
Answer:
E. A conductor is needed for electricity to flow in a circuit.
Explanation:
Electric current can flow without a resistor, as in short circuit.
A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.
Without a switch, electricity can flow in a circuit, switch is only used to close or open the circuit.
Thus, the only correct option is E
E. A conductor is needed for electricity to flow in a circuit.

Contains elements carbon, hydrogen and oxygen, the empirical formula of butanedion is C2H3O and its molar mass is 86.09% find its empirical formula
Answer:
Molecular formula = C₄H₆O₂
Explanation:
Given data:
Empirical formula of butanedion = C₂H₃O
Molar mass of butanedion = 86.09 g/mol
Molecular formula butanedion = ?
Solution:
Formula:
Molecular formula = n(empirical formula)
n = molar mass of compound / empirical formula mass
empirical formula mass = 2×12 +1.008×3 +1×16 = 43.024
n = 86.09 / 43.024
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₂H₃O)
Molecular formula = C₄H₆O₂
A dark blue beaker labeled 100 millimeters Y has an arrow leading to a pale blue beaker labeled 99 millimeters H subscript 2 O. This has an arrow leading to a white beaker labeled 99 millimeters H subscript 2 O. Each arrow has a label 1 milliliter over it. The dark blue beaker has a box below it labeled Beaker number 1. The pale blue beaker has a box below it labeled Beaker number 2. The white beaker has a box below it labeled beaker number 3.
Does taking 1 mL of solution Y (pure bleach) out of the first beaker change the solution’s concentration?
What would the concentration of the second beaker be?
If Beaker #2 is a 1% solution of Y, and Beaker #3 is 1/100th of that in the final solution, what percentage solution would Beaker #3 be?

Convert each measurement into scientific notation. For example, 8.73 Ms is the same as 8.73 x 106 because the “M” stands for 106
107pg
(I'm assuming I have to convert the 107pg but I am unsure of how to answer this)
Answer:
[tex]107pg = 107 \times {10}^{ - 12}g =1.07 \times {10}^{ - 10} g\\ because \: pico, \: p = {10}^{ - 12} .[/tex]

a sample of alcohol has a density 0.82 g/ml.what is the mass of 5500 mL of the alcohol
Answer:
The answer is 4510 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density = 0.82 g/mL
volume = 5500 mL
We have
mass = 0.82 × 5500
We have the final answer as
4510 gHope this helps you
Explain the difference between potential energy and kinetic energy.
Sentence Starters
"Potential Energy is. . "
"Kinetic Energy is. . "
"The difference between potential energy and kinetic energy is. . ."
Answer:
Potential energy is the stored energy in an object or thing, while kinetic energy is the energy which an object contains because of a particular motion.
Explanation:
Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.
The difference is that potential is stored and kinetic is moving energy.
What colors are the fireworks in the photo? How do you
think the matter and energy of fireworks of different colors are similar and
different?
Answer:
Shortly after, the electron will fall back down to a lower energy level, releasing energy in the form of light. Therein lies the key to colorful fireworks!
The matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage.
What is Matter?Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.
When the electrons move from the ground stage to the excitatory stage, they require a significant amount of energy in any form. But when they fall back to the ground stage from the excitatory stage, they liberates energy.
The same principle is applied in the colorful observation of fireworks. The stored energy is released and different colors of fireworks become visible.
Therefore, the matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage and vice-versa.

Mr. Bullis wants to know if he gives teachers candy, it will make them smile more. He gives half the teachers candy and the other half get nothing. He then records the number of times the teachers smiled.
Experimental Group:
Control Group:
Answer:
the experimental group would be the teachers who recieved the candy
control group would be the teachers who dont get any candy
Explanation:
experimental group is the group that receives the test variable being tested in this case the variable being the candy
and the control group is the group who doesn't receive the variable
purpose of having a control is to rule out other factors which may influence the results of an experiment.

explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps
The balance of chemical equation : 2KClO₃ ⟶ 2KCl + 3O₂
Further explanationEqualization (balance) of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc. 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product 3. Select the coefficient of the substance with the most complex chemical formula equal to 1Reaction
[tex]\tt KClO_3\Rightarrow KCl+O_2[/tex]
1. Coefficient
KClO₃ ⟶ aKCl + bO₂
2. Equation
K ⇒ left =1, right=a ⇒a=1
Cl⇒ left =1, right=a ⇒a=1
O ⇒ left = 3, right = 2b ⇒3=2b, b = 1.5
The equation turns into :
KClO₃ ⟶ KCl + 1.5O₂
multiplied by 2
2KClO₃ ⟶ 2KCl + 3O₂
Why do acids and bases neutralize eachother?
Answer:
Explanation:
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
