Answer:
The correct answer is C. None of the above.
Explanation:
To determine how long the black bear will run, the distance it will travel must first be determined. Thus, the proposed calculation must be solved.
1.95 x 10 ^ 4
1.95 x 10 x 10 x 10 x 10
19.5 x 10 x 10 x 10
195 x 10 x 10
1950 x 10
19500
Thus, the bear will run 19,500 miles, so, running at 35 mph, it will take about 557 hours to run that distance (19,500 / 35).

A deck of cards has dimensions 8.9cm x 5.72cm x 1.82 cm. What is the volume of the deck in cubic centimeters?
The volume of the deck having dimensions 8.9cm x 5.72cm x 1.82 cm is 92.65 cubic centimeters.
How to find the volume of the Cube ?The volume of a cube is obtained by multiplying its side three times. The formula of volume of the cube can thus be given as, Volume of cube = s³, where s is the side length of the cube.
Given ;
Length : 8.9cmBreadth : 5.72cmHeight : 1.82 cmFormula used ;
Volume = Length x Breadth x Height
= 8.9cm x 5.72cm x 1.82 cm.
= 92.65 cm³ i.e, 92.65 cubic centimeters

A deck of cards has dimensions 8.9cm x 5.72cm x 1.82 cm. What is the volume of the deck in cubic centimeters?
Answer:
92.65256 cm^3
Explanation:
To find this, we can simply multiply all three dimensions to get the answer in cubic centimeters, and we get the answer above. If you want to be more specific, we can go by the sigfig rule and the answer would be rounded to 93 cm^3.

Explanation:
Hot air rises, and land heats up first.
Answer:
Here are the answers:
1.) land
2.) water
3.) warmer
4.) rises
5.) sea
Explanation:
During a day at the beach, the land heats up faster than the water. Because of this, the air over land rises over the land and the cooler, more dense air, blows into the ocean, creating a sea breeze.

What are valence electrons? How do you quickly determine the number of valence electrons an
atom has?
Answer:
Electrons that arent electrons
Explanation:
I teach chem
Answer:
Valence electrons are the electrons found in the highest and main energy level of the atom, being these responsible for the interaction between atoms of different species or between atoms of the same species. You can quickly determine these by looking at a periodic table like this one... Which is where the roman numbers come in and show the valence electrons. (THIS TABLE IS IN SPANISH, I hope you still recognize the symbols.) :))

Calculate the number of molecules in 2.00 moles H2S.
Express your answer numerically in molecules.
Answer:
The answer is
1.204 × 10²⁴ moleculesExplanation:
The number of molecules can be found by using the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2 × 6.02 × 10²³
We have the final answer as
1.204 × 10²⁴ moleculesHope this helps you
In a certain chemical reaction, the bond energy of the products is 67 kJ and
that of the reactants is 52 kJ. Because energy is conserved, how much
potential energy does the system release or absorb?
O A. The reaction uses up 15 kJ of energy from the reaction system.
B. The reaction creates 15 kJ of energy when bonds form.
C. The reaction system absorbs 15 kJ of energy from the
surroundings.
O D. The surroundings absorb 15 kJ of potential energy.
D. The surroundings absorb 15 kJ of potential energy.
Further explanationChemical bonds = potential energy
ΔH reaction from bond energy is a breaking and forming reaction of the 2 reacting molecules
Can be formulated:
ΔH rxn = ∑ the energy of the reagent bonds broken - ∑ the energy of the bonds formed by the product
The bond energy of the products is 67 kJ and reactants 52 kJ
[tex]\tt \Delta H_{rxn}=52-67=-15~kJ[/tex]
ΔH = negative ⇒The reaction is exothermic(releases heat to surrounding)

Air masses that form over large bodies of water are moist. What process determines the amount of moisture in an air mass?
Answer:
I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

Write a balanced equation for each of the acid-base reaction given below.a. Aqueous sulfuric acid with aqueous potassium hydroxide.
Answer:
H2SO4 + 2KOH => K2SO4 + 2H2O
Explanation:
The acid-base reaction is a type of chemical reaction that involves the exchange of hydrogen ions.
The acid-base reaction between aqueous sulfuric acid ( H2SO4 ) and aqueous potassium hydroxide (KOH) is a neutralization reaction that results in potassium sulfate and water.
sulfuric acid + potassium hydroxide => potassium sulfate + water
So, the balanced equation for this reaction is as follows:
H2SO4 + 2KOH => K2SO4 + 2H2O
Hence, the correct answer is "H2SO4 + 2KOH => K2SO4 + 2H2O".
