Explanation:

ATP provides a source of chemical energy that powers all cell functions.

Any process in the body that requires energy relies on the conversion of ATP to ADP and the associated release of chemical energy. Therefore, movement, growth, and development all use ATP to take place.

Answer : The cost of pennies to buy 125 L of gasoline would be, $71.92

Explanation :

As we are given that the cost to buy gasoline is $2.186/gallon.

Now we have to determine the cost to buy 125 L of gasoline.

First we have to convert 125 L into gallon.

Conversion used:

(1 gallon =  128 oz, 1 oz= 29.6 mL, 1 mL = 0.001 L)

As, 1 L = 1000 mL

So, 125 L = 125000 mL

and,

As, 29.6 mL = 1 oz

So, 125000 mL = [tex]\frac{125000mL}{29.6mL}\times 1oz=4222.9oz[/tex]

and,

As, 128 oz = 1 gallon

So, 4222.9 oz = [tex]\frac{4222.9oz}{128oz}\times 1\text{ gallon}=32.9\text{ gallon}[/tex]

Now we have to determine the cost to buy 125 L of gasoline.

As, the cost of 1 gallon of gasoline = $2.186

So, the cost of 32.9 gallon of gasoline = $2.186 × 32.9

                                                                = $71.92

Therefore, the cost of pennies to buy 125 L of gasoline would be, $71.92

Chemical formula

Explanation:

because chemical formulas use chemical elements , symbols , and numbers to present information about the chemical proportions.

Answer:

λ  = 3.0 × 10⁻¹² m

Explanation:

Speed of Light = Wavelength × frequency

c = λν

Step 1: Define

c = 3.0 × 10⁸ m/s

λ = unknown

ν = 1 × 10²⁰ Hz

Step 2: Substitute and Evaluate for λ

3.0 × 10⁸ m/s = λ · 1 × 10²⁰ Hz

λ = 3.0 × 10⁸ m/s ÷ 1 × 10²⁰ Hz

λ  = 3.0 × 10⁻¹² m

Answer: C

Explanation: They pasteurize the juice to make it safe to drink.

The sentence which uses pasteurization correctly is that they  pasteurize the juice to make it safe to drink.

Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process.

The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine.Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.

Answer:

sp2

Explanation:

Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.

C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is  sp2 hybridized.

Hence, the correct answer is "sp2".

The hybridization of the C atoms in C2Cl4 is sp² hybridized.

The concept of hybridization deals with the merging of atomic orbitals to produce fresh hybridized orbitals, which impact molecule geometry and bonding characteristics.

In the given compound, C2Cl4 (tetrachloroethene)

There is a substitution of all the hydrogen atoms attached to the organic compound ethene with chlorine to produce tetrachloroethene. The two carbon atoms are doubly bonded to each other with two chlorine attached to each of the carbon atoms diagonally given rise to a bond angle of 120°.  Thus, the resulting hybridization of the C atom is sp² hybridized.

Therefore, we can conclude that the hybridization of the C atoms in C2Cl4 is sp² hybridized.

Answer:

Newton's Second Law

Explanation:

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

(I'm going to assume this is an option, but please let me know if it's not!)

There are two forms of chemical equations

Ion equation: written in ion form (as separated ions) which forms the net ionic equation after removing an ion spectator

Molecular equation: written in molecular form

2AgNO₃(aq) + H₂S(aq) ⇒ Ag₂S(s) + 2HNO₃(aq)

The above reaction can be included in a double replacement reaction⇒ an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

It can be shown the existence of the precipitation reaction, which is the formation of insoluble Ag₂S (not dissolve)

Answer:

exactly 25 g​

Explanation:

The mass of an object is universally the same every where. Even in outer space.

This is because, mass is the amount of matter contained in a substance. Since there is no loss in the amount of matter, the mass of the body stays the same.

Mass accounts for every individual matter present in a substance.

When they remain the same, mass does not change. Only a change in the amount of matter in a body can cause variation in mass.

Therefore, at the bottom of the ocean, a body will have the same mass as on top and even at sea level.

Suspension

Explanation:

Answer:

1 cc=1 ml=0.001 liter

Explanation:

One cubic centimeter has the same volume as one milliliters. Both are equally used in analytical problems to express the volume of a substance.

Volume is a physical quantity that measures the total space occupied by a substance. Volume is an extensive quantity and thus depends on the amount of the substance.

The mass of a substance per unit volume is called its density. Volume is dependent on the intermolecular forces between the particles of the substance. The SI unit of volume is liter (L). Other units are ml, cm³, dm³ etc.

One cubic centimeter has the volume as one milliliters.

Hence, 1 cm³ = 1 ml

1000 m or 1000 cm³ is one liter of the substance.

Answer:

Explanation:

Ionization energy:

It is the minimum amount of energy required to remove the electron from isolated gaseous atom to make the ion.

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell.

When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.  Where as,

When we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
