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.

B When the molecule contains polar bonds.

Explanation:

AP-EXpert

The shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

The polarization of a molecule greatly depends on the shape of the molecule. The net dipole moment occurs only due to the uneven distribution of electrons between the two atoms.

So we can conclude that the shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

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!)

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.

Answer:

Option d is correct = Negative ion

Explanation:

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg  and 1.674929×10⁻²⁷ Kg  respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The  umber of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.

When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion. For example,

Anion formation:

X + e⁻ → X⁻

Cation formation:

X → X⁺ + e⁻

Thus option d is correct option.

I don't understand what you are asking

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

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

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.

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.
