Which unit conversion allows you to convert 21.0 gallons into milliliters?
Some English and English-metric unit relationships: 1 liter = 1.057 quarts, 1 gallon = 4 quarts
Answers
Answer:
Explanation:
we are given
there are in 0.073 gallons
we can see that there are two non-zero places after decimals
so, there are two siginificant figures
step-1: Change gallons to quarts
we know that
1 gallon = 4 quarts
so, we can write as
step-2: Change into liter
we know that
1 liter = 1.057 quarts
or
step-3: Change into millilitre
we know that
Since, it is asking for only two significant figures
so, we can also write as

O
O
O
C. The rate of the reaction begins to decrease as reactants are used
up
O
D. The rate of the reaction stays constant until the reactants are
gone.
Answers
The rate of the reaction depicts the speed at which the reaction occurs to produce the products. As the reactants get used up the reaction rate starts decreasing. Thus, option C is correct.
What are the factors affecting reaction rate?
The reaction rate of the chemical reaction gets affected by numerous factors that include temperature, the concentration of the reactants, catalyst, surface area, and physical state of the reactant.
The concentration of the reactant has a direct effect on the reaction rate as they are the deciding factor of the product formation. At the beginning of the reaction, the speed is fast compared to the end.
As the reactants start getting used up the reaction rate slows down as the molecules are not able to collide faster with other molecules to form the product.
Therefore, in option C. the reaction rate decreases with a decrease in concentration.

Why does the border between light and dark on the Moon change location?
Answers
We only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.
What is solar system?Solar system is defined as the Sun's orbiting objects are confined by gravity to one system. The Solar System is the only system in which a habitable planet has been observed, the only star we can observe up close, and the only planets we can explore with spacecraft. Understanding the creation and evolution of planets as well as the conditions required for life requires extensive investigation into the solar system.
The terminator is the line on the moon that divides day from night. The moon's surface is in a twilight state along the terminator line, which is where the twilight zone is frequently referred to as. The sun is either rising or setting on the moon along this line.
Thus, we only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.

The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.
What is reactivity series?Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.
According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au
So, zinc will replace the nickel atom from NiCl₂ solution.
Hence option (D) is correct.

Alcoholic fermentation
Anaerobic respiration
Lactic acid fermentation
The production of energy without the presence of oxygen
A process that converts sugars into cellular energy, ethanol, and carbon dioxide
A process that converts sugars into cellular energy, ethanol, and carbon dioxide
The breakdown of food to create energy in the presence of oxygen
Answers
Answer:
Aerobic respiration is metabolic process in which food ( glucose) is metabolized ( in presence of oxygen) to derive large amount of energy ( in the form of ATP) through a series of three stages that is glycolysis, kreb cycle, and electron transport chain.
Anaerobic respiration another from of cellular respiration where food is broken down to derive energy in the absence of oxygen.
Alcoholic fermentation is a metabolic process by which sugar is converted into cellular energy ( in the form of ATP), ethanol, and carbon dioxide.
Lactic acid fermentation is a metabolic process by which glucose is converted into cellular energy and lactic acid.
Thus, the correct match is-
Aerobic respiration- A) The breakdown of food to create energy in the presence of oxygen.
Alcoholic fermentation- C) A process that converts sugars into cellular energy, ethanol, and carbon dioxide.
Anaerobic respiration- B) The production of energy without the presence of oxygen.
Lactic acid fermentation- D) A process that converts glucose into cellular energy and lactic acid.
Explanation:
Answer:
Aerobic respiration – The breakdown of food to create energy in the presence of oxygen
Alcoholic fermentation – A process that converts sugars into cellular energy, ethanol, and carbon dioxide
Anaerobic respiration – The production of energy without the presence of oxygen
Lactic acid fermentation – A process that converts glucose into cellular energy and lactic acid

Answers
Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.
Explanation:
Option A is correct. The statement that best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".
The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".
The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).
In conclusion, the statement best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".

Answer:

Explanation:
The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:
In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge. What are Non-metals?Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.
In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.
The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.
Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.
