Answer:
Where can you find most of Earth's liquid freshwater?
Explanation:
Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
Hope that helped, i also have snap if you need me.
Over 68 per cent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 per cent is found in groundwater. Only about 0.3 per cent of our freshwater is found in the surface water of lakes, and rivers.
What is the per cent of the water on this earth?The Earth is a watery place. About 71 per cent of the Earth's surface is water-covered, and the oceans hold about 96.5 per cent of all Earth's water.
The majority of Earth’s fresh water is stored in underground aquifers.
Aquifers are layers of sedimentary formations such as sandstone and fractured hard rocks where water after infiltration from soil reaches and fill the interstitial spaces.
Aquifers are huge in size in basins and contain a huge amount of underground water of fresh quality.
So, over 68 per cent of the freshwater is present on Earth.

Which of the following correctly
states the difference between
elements and compounds?
Elements and compounds are the
same because they are both made of
atoms,
An element is made of two or more
types of atoms combined, while a
compound is made of one type of
stom,
An element is made of one type of
tcom, while a compound is two or
more types of stoms combined.
Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.
Explanation:
An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.
Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.
There are over a hundred elements known to date. Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek Examples are copper, gold, ironThe properties of a compound are distinct and different from those of the individual elements that are combined in its make up. There are several millions of compounds known. They are usually represented by chemical formulae.As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.

E. Give evidence to support or dispute: "In nature, the chance of finding one isotope
of an element is the same for all elements." (this objective is completed by
responding to question 2 below)
Answer:
This question appears incomplete
Explanation:
However, the chance of finding one isotope of an element is not the same for all elements because some elements/isotopes are more in abundance than some other elements/isotopes; for example the most abundant element on earth is nitrogen-14, hence the chances of finding nitrogen-14 in nature is higher the chances of finding any isotope of Xenon.
Also, while isotopes occur naturally, some do not. Hence, the chances of finding a naturally occurring isotopes (no matter how rare like Xenon-126) is higher than the chances of finding artificial radioisotopes like technetium-95 and promethium-146 (whose chances are zero because they cannot be found naturally occurring).

Use the PhET simulation to identify what happens to the concentrations of a dilute Drink mix mixture or a pure Drink mix solution for the following scenarios. A pure Drink mix solution can be obtained by draining all the mixture, then adding Drink mix to the container as a Solution (radio button in the upper right area of the simulation). Note that the Concentration meter can be placed toward the bottom of the container or in the stream of the Drink mix. Drag the appropriate items to their respective bins.

which of the following is NOT a characteristic of minerals
A. Occur in gaseous and liquid state
B. Formed by inorganic processes
C. naturally occurring
D. definite chemical composition
Answer:
A. Occur in gaseous and liquid state
Explanation:
The choice that is not a characteristic of minerals is that minerals occur in gaseous and liquid state.
All minerals are solid inorganic compounds.
A mineral is an inorganic compound that is formed naturally. They have a definite and specific chemical composition. Minerals are the building blocks of rocks. When minerals aggregates together, they form different rock types. There is no known mineral that is in fluid state. All minerals are solids. Examples are quartz, kaolinite, gypsum e.t.cFor a reaction Y → X with a very high equilibrium constant, K, which of the following is true? You can refer to the following two equations in formulating your answer.$$$$Choose one:A. The standard free-energy change is large and positive.B. The amount of product and substrate are equal at equilibrium.C. The forward reaction rate greatly exceeds the reverse reaction rate at equilibrium.D. The amount of product will be higher than the amount of substrate at equilibrium.
Answer:The amount of product will be higher than the amount of substrate at equilibrium
Explanation:
Recall that the equilibrium constant K depends on the amounts of reactants and products present in the system at equilibrium.
Considering the equation; K = [X]/[Y], as the concentration of X increases above that of Y, the equilibrium constant K becomes very high, hence the answer above.

Why is Cobalt (Co) placed before Nickel (Ni) on the Periodic Table of the Elements even though it has a higher average atomic mass than nickel?
Nickel has fewer electrons.
Cobalt has a lower density.
Cobalt was discovered first.
Nickel has one more proton.
Answer: Nickel has one more proton.
Explanation:
The Periodic table orders elements based on their atomic number not by their atomic mass even though this order usually coincides with the atomic masses of the elements. Occasionally however, this is not the case as is proven by Cobalt and Nickel.
The atomic number of an element refers to the number of protons that the element has in its nucleus. Cobalt has 27 protons whilst Nickel has one more proton at 28 which is why it comes after Cobalt.
Answer:
lower density
Explanation:

write the molecular formula for the following compound.
Answer : The molecular formula of the compound is, [tex]C_8H_9O_3N[/tex]
Explanation :
Molecular formula : It is the representation of substance by the symbols and it denotes the number of atoms of each element present in the compound.
Now count the number of carbon, hydrogen, nitrogen and oxygen atoms present in the given compound.
As we see that in the given compound, there are 8 atoms of carbon element, 3 atoms of oxygen element, 1 atom of nitrogen element, 9 atoms of hydrogen element.
Thus, the molecular formula of the compound will be [tex]C_8H_9O_3N[/tex]
