They pasteurize the juice to make it safe to drink.

We decided to pasteurize the documents for safekeeping

Answers

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.

What is pasteurization?

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.

What is the hybridization of the C atoms in C2Cl4 ?

Answers

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.

at the bottom of the ocean a rock has a mass 25 g. At sea level the same rock wilk have a mass of:
less than 25 g
more than 25 g
exactly 25 g​

Answers

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.

It is weight that is subjected to changes with the value of gravity. Weight differs from places to places. A place with higher gravity will have a higher value of weight for any given mass.

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:

c. exactly 25 g

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

What is the effect on polarity?

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.

At $2.186/gallon, how many pennies would it cost to buy 125 L of gasoline? (1 gallon =
128 oz, 1 oz= 29.6 mL)


PLS HELPPPP

Answers

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

Which describes an atom that has fewer neutrons than protons and more electrons than protons?

0negative compound
0positive compound
0positive ion
0negative ion

Answers

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.

A gamma ray has a frequency of 1 x 10^20 Hz and has a speed of c. What is the

Answers

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

Answers

Answer:

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.

What is volume ?

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.

Please help hurry!! This is due in 30 minutes and I need help with domain and range. Explain the differences between a partnership and a corporation The following disclosures (excerpted) are from the September 2, 2018, annual report of Costco Wholesale Corporation.The Company generally recognizes sales, net of returns, at the time the member takes possession of merchandise or receives services. When the Company collects payments from members prior to the transfer of ownership of merchandise or the performance of services, the amounts received are generally recorded as deferred sales, included in other current liabilities in the consolidated balance sheets, until the sale or service is completed. The Company reserves for estimated sales returns based on historical trends in merchandise returns and reduces sales and merchandise costs accordingly. The Company accounts for membership fee revenue, net of refunds, on a deferred basis, ratably over the one-year membership.The Companys Executive members qualify for a 2% reward on qualified purchases (up to a maximum reward of approximately $1,000 per year), which can be redeemed only at Costco warehouses. The Company accounts for this reward as a reduction in sales. The sales reduction and corresponding liability (classified as accrued member rewards in the consolidated balance sheets) are computed after giving effect to the estimated impact of non-redemptions, based on historical data.
