What type of energy is stored in fuels such as gasoline and batteries
Answer:Chemical energy
Explanation:Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine.
The type of energy which is stored in fuels such as gasoline and batteries is chemical energy.
What is chemical energy?
Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.
Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.
It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.

Descibe how electronegativity and molecular shape determine the polarity of a molecule. Then describe why chemists consider relative electronegativity values and not absolute electronegativity values when determining the polarity of a bond. Also explain how a molecule with polar bonds can be non-polar overall.
Answer:
See explanation
Explanation:
Electronegativity is an idea put forward by Linus Pauling to explain the fact that in a molecule, one atom may attract the shared electrons of the bond closer to itself than the other.
Hence electronegativity is defined as the power of an atom in a molecule to attract electrons to itself.
Pauling originally described electronegativity as a relative quantity. It depends on the electronegativities of the atoms in the molecule. However, some methods have sought to measure the absolute electronegativity of a free atom.
A bond is polar when the atoms that make up the bond have a significant difference between the atoms of the molecule.
However, a molecule may possess polar bonds but may not have an overall dipole moment owing to the shape of the molecule.
For instance, CCl4 has four polar C-Cl bonds but the overall molecule is non polar because due to the fact that the molecule is tetrahedral in shape and highly symmetrical hence the individual dipoles cancel out.

Antonio and his friend found a piece of metal which they want to identify. Here is what they figure out so far: Mass of this metal is 20g Volume of this metal is 2.35cm3
Answer:
The density of beryllium copper is 8.5 g/cm³ thus given metal is beryllium copper.
Explanation:
Given data:
Mass of metal = 20 g
Volume of metal = 2.35 cm³
Which metal is this = ?
Solution:
we will apply density formula to solve this problem.
d = m/v
d = density
m = mass
v = volume
d = 20 g/ 2.35 cm³
d = 8.5 g/cm³
The density of beryllium copper is 8.5 g/cm³ thus given metal is beryllium copper.

how many grams of S are in 665 g of SO2
Answer: 111g S
Explanation:
SO2 you have = 665 g
SO2 molar mass = 64.066 g/mol
S molar mass = 32.065 g/mol
[tex]665g SO2*\frac{1 molSO2}{64.066gSO2} *\frac{1molS}{3molSO2} * \frac{32.065gS}{1molS} = 110.944... ~ 111gS[/tex]
There are 332.5 grams of S (sulfur) in 665 g of SO2 ( sulfur dioxide).
From the information given:
The atomic mass of sulfur = 32 g/mol
The atomic mass of oxygen = 16 g/mol
∴
The molar mass for SO2 = 32 + (16 × 2) g/molThe molar mass for SO2 = 64 g/molSince there are 665g of SO2;
If 1 mole of SO2 contains 1 mole of S
It implies that:
(1 × 64)g of SO2 will contain (1 × 32) g of S;
∴
665 g of SO2 will contain :
[tex]\mathbf{= \Big ( \dfrac{1 \times 32}{1 \times 64} \times 665 \Big )}[/tex]
= [tex]\mathbf{\Big 332.5 \ grams \ of \ S \Big}[/tex]
Therefore, we can conclude that there are 332.5 grams of S present in 665 g of SO2.

B) 8000 meters
C) 6000 meters
D) 1200 meters
Answer:
C) 6000 meters.
Explanation:
Hello.
In this case, since the speed is computed as the distance divided by the time to attain such displacement:
[tex]s=\frac{d}{t}[/tex]
Knowing that the speed is 1500 m/s and the required time is 4 s because is the half of the described travel, the distance is then:

A balance reads an object A to be 45.1 kg. The balance reads another object B to be 33.46 kg. What is the total weight of both objects
Answer:
The total weight of both object is 78.56 kg.
Explanation:
Given data:
Mass of object A = 45.1 kg
Mass of object B = 33.46 kg
Total weight of object = ?
Solution:
Total weight of both subject must be the sum of weight of object A and B.
Total weight of objects = weight of object A + weight of object B
Now we will put the values of mass of object A and B.
Total weight of objects = 45.1 kg + 33.46 kg
Total weight of objects =78.56 kg
Thus the total weight of both object is 78.56 kg.

B
cells are not a level of organization in a living organism.
C
cells alternate between being the highest and lowest level of organization in a living organism.
D
cells are the lowest level of organization in a living organism.
Answer: A
Explanation:
Robert Hooke discovered the cell. Cells are the highest level of organization in a living organism. so, option A is correct.
What is cell ?Cell is the smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. It is a small unit of organism containing nucleus.
The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates how substances enter and exit the cell.
After using a very early microscope to examine a piece of cork, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber." It is also claimed that he believed the rectangular chambers to resemble some monastic cells.
Thus, option A is correct.

Carbon combines with oxygen to form two compounds, carbon monoxide and carbon dioxide. Based on the law of multiple proportions, describe how the proportions of oxygen in the two compounds relate to each other.
Answer:
Their components
Explanation:
It's simple enough, the components in carbon dioxide and carbon monoxide both have at least one carbon and one oxygen atom. However, they differ because their amount in the molecules is different, and that is because of their covalent bonds. Carbon dioxide has to double electron bonds while carbon monoxide has a rare triple electron bond.

Answer:
Frequency =0.634×10¹⁵ s⁻¹
Explanation:
Given data:
Wavelength = 4.73×10⁻⁷ m
Frequency = ?
Solution:
Formula:
speed of light = wavelength× frequency
speed of light = 3×10⁸ m/s
Now we will put the values in formula.
3×10⁸ m/s = 4.73×10⁻⁷ m × frequency
Frequency = 3×10⁸ m/s /4.73×10⁻⁷ m
Frequency =0.634×10¹⁵ s⁻¹
s⁻¹ = Hz
Frequency =0.634×10¹⁵ Hz
