Explanation:
simile is a figure of speech that compares two different things in an interesting way. The object of a simile is to spark an interesting connection in a reader's or listener's mind. A simile is one of the most common forms of figurative language. Examples of similes can be found just about anywhere from poems to song lyrics and even in everyday conversations.
Similes and metaphors are often confused with one another. The main difference between a simile and metaphor is that a simile uses the words "like" or "as" to draw a comparison and a metaphor simply states the comparison without using "like" or "as".
An example of a simile is: She is as innocent as an angel. An example of a metaphor is: She is an angel. Do you see the difference? The simile makes a direct comparison, the metaphor's comparison is implied but not stated.

how many moles are in 1.02 x 10^23 atoms of argon gas
Answer:
0.17 mol
Explanation:
Given data:
Number of atoms of Ar gas = 1.02×10²³ atom
Number of moles = ?
Solution:
The given problem will solve by using Avogadro number.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
1.02×10²³ atom × 1 mol / 6.022 × 10²³ atoms
0.17 mol
Avogadro number:

Answer:
Balanced, Unbalanced, Unbalanced, Balanced, Unbalanced.
Explanation:
A student sitting at a desk has no kinetic energy, he/she/they are not moving or exerting force. A rocket taking off is in the process of releasing energy, pushing the rocket upward, attempting to balance the forces of gravity and downward force. A building collapsing has kinetic energy, as gravity has now become greater than that of the force pushing against it. A satellite has balanced force because nothing is acting upon it other than gravity, at which distance, by the fact that is orbiting, is not moving towards or away from the item which has put force on it. When you are in a car at a constant speed, you may move in it as if it is stationary, because the friction on the wheels and wind speed create balanced forces against the engine. From outside of the car, these forces are unbalanced, as the car is propelled, which is what I believe the question is asking.

Tin fluoride, SnF2, is used in some toothpastes. It is made by the reaction of tin with hydrogen fluoride according to the following equation: Sn(s) + 2HF(g) --> SnF2(s) +H2(g). If a toothpaste manufacturer reacts 30.00 of HF with enough tin, how many grams of SnF2 can they expect to get?
Please show your work or how you got the answer, I really need it.
Mass of SnF2 : 117.53 g
Further explanationGiven
Reaction
Sn(s) + 2HF(g) --> SnF2(s) +H2(g).
30 g of HF
Required
mass of SnF2
Solution
mol HF (MW= 20 g/mol) :
= mass : MW
= 30 : 20
= 1.5
From the equation, mol ratio of HF : SnF2 = 2 : 1, so mol SnF2 :
=1/2 x mol HF
= 1/2 x 1.5
= 0.75
mass SnF2(MW=156.71 g/mol) :
=mol x MW
= 0.75 x 156.71
= 117.53 g
What type of specialized cell in the eye is used for detecting low levels of light?
rod cell
cone cell
blood cell
stem cell
Answer:
Cone Cell
Explanation:
There are about six to seven million cones in a human eye and are most concentrated towards the macula. Cones are less sensitive to light than the rod cells in the retina (which support vision at low light levels), but allow the perception of color.

Plutonium is part of what series of elements?
Answer:
Plutonium is the second transuranium element of the actinide series.
The main fuel for a fast neutron reactor is plutonium, which is gradually created in any reactor from non-fissile U-238, which makes up more than 99% of natural uranium. The actinide series' second transuranium element is plutonium.
Pu is the atomic symbol for plutonium, which bears the numbers 94 and 244 in its atomic weight. On a periodic chart, plutonium is located in period 7, which is part of the actinides group.
With an atomic number of 94, plutonium is the second transuranic element and a member of the actinide group on the periodic table. Like its precursor, neptunium, which was named after the planet Neptune, Plutonium is named after the planet Pluto.

Which Earth motion describes the wobbling of the Earth around its precessional axis and
could alter the amount of seasonal effects? *
Precession
Nutation
Barycenter
Revolution
Answer:
Nutation
Explanation:
The counterclockwise rotation of planet earth around its own axis is defined as the Earth Rotation. The earth rotates about the line called "the axis of rotation," it is an imaginary line that passes through the North and South Poles of the planet, which the earth rotates about.
Hence, earth rotates once in about 24 hours with respect to the Sun, from West to East and thus giving rise to;
a. Day and night
b. Seasons
The Earth motion which describes the wobbling of the Earth around its precessional axis and could alter the amount of seasonal effects is known as nutation.
Basically, nutation usually occurs when the precessional motion of a planetary body such as planet earth experience some form of irregularities when it is rotating.

what volume of carbon 4 oxide measured at STP will produce when 21 gram of sodium hydrogen carbonate for is completely decomposed accor. ding to the equation. (Na=23. H=1 C=12 O=16) molar vol =22.4dmcube. pleeeeeeeeeeese help
The volume of CO₂ at STP = 2.8 L
Further explanationGiven
21 gram of sodium hydrogen carbonate-NaHCO₃
Required
Volume of CO₂
Solution
The decomposition of sodium bicarbonate into sodium carbonate, carbon dioxide, and water :
2 NaHCO₃(s) → Na₂CO₃(s) + CO₂(g) + H₂O(g)
mol of NaHCO₃ :
= mass : MW NaHCO₃
= 21 g : 84 g/mol
= 0.25
From the equation, mol ratio of NaHCO₃(s) :CO₂(g) = 2 : 1, so mol CO₂ :
= 1/2 x mol NaHCO₃
= 1/2 x 0.25
= 0.125
At STP, 1 mol gas = 22.4 L, so for 0.125 mol :
= 0.125 x 22.4 L
= 2.8 L
What does the host mean when he says that the acid has "donated a proton" to the water?
A.
When hydrochloric acid is dissolved in water, a proton disappears in the chemical reaction.
B.
When hydrochloric acid dissociates, a positive hydrogen atom is accepted by water to form H₃O+.
C.
When hydrochloric acid dissociates, a negative hydrogen atom is accepted by water to form H₃O-.
Answer:
Option B
Explanation:
As Brønsted-Lowry theory states, acids are the ones that can donate protons.
When a proton is donated, it is released to become medium more acidic.
HCl is a strong acid.
HCl (l) + H₂O (l) → H₃O⁺ (aq) + Cl⁻(aq)
These always reffers to strong acid where the dissociation is 100% completed.
In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.
HA (l) + H₂O (l) ⇄ H₃O⁺ (aq) + A⁻(aq) Ka
If a container holds 5.00 moles of gas and the total pressure is 5.00 atm., what is the partial pressure for each mole of gas?
Answer:
1 atm
Explanation:
From the question given above, the following data were obtained:
Total mole = 5 moles
Total pressure = 5 atm
Partial pressure for each mole =.?
Next, we shall determine the mole fraction for each mole of the gas. This is illustrated below:
Since the container holds 5 moles of gas, then the mole fraction for each mole of the gas will be 1/5.
Finally, we shall determine the partial pressure for each mole of the gas as follow:
Mole fraction for each mole = 1/5
Total pressure = 5 atm
Partial pressure for each mole =.?
Partial pressure = mole fraction × total pressure
Partial pressure = 1/5 × 5
Partial pressure = 1 atm
Thus, the partial pressure for each mole of the gas is 1 atm.

Determine the number of milliliters of 0.00300 M phosphoric acid required to neutralize 40.00 mL of 0.00150 M calcium hydroxide.
The volume of H₃PO₄ : 13.33 ml
Further explanationGiven
0.003 M Phosphoric acid-H₃PO₄
40 ml of 0.00150 M Calcium hydroxide-Ca(OH)₂
Required
Volume of H₃PO₄
Solution
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence (amount of H⁺/OH⁻)
H₃PO₄⇒3H⁺ + PO₄³⁻ ⇒ 3 H⁺ = valence = 3
Ca(OH)₂⇒Ca²⁺ + 2OH⁻⇒ 2 OH⁻ = valence = 2
Input the value :
a = H₃PO₄, b = Ca(OH)₂
0.003 x Va x 3 = 0.0015 x 40 x 2
Va = 13.33 ml
