Which sentence uses pasteurize correctly?
The painter must pasteurize the scene in pastel colors.
The cows were put in the field to pasteurize.
They pasteurize the juice to make it safe to drink.
We decided to pasteurize the documents for safekeeping
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.

In going across a row of the periodic table, protons and electrons are added and ionization energy generally increases. In going down a column of the periodic table, protons and electrons are also being added but ionization generally decreases. Explain.
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.

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
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

what is the molecular equation to AgNO3 (aq) + H2S(aq)?
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:
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.
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.

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
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
