When naming acids the prefix hydro- is used when the name of the acid anion ends in___
Answer:
hydrochloric acid
Explanation:
These anions usually have the ending “-ide.” As acids, these compounds are named starting with the prefix “hydro-,” then adding the first syllable of the anion, then the suffix “-ic.” For example, HCl, which is hydrogen and chlorine, is called hydrochloric acid. More complex acids have oxygen in the compound.

paragraph on water cycle
Answer:
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... These areas are usually close to oceans or large bodies of water that allow more water to evaporate and form clouds.
Explanation:
Which of the following does not apply to water molecules?
Water molecules are polar
Water has cohesive properties
Water is less dense as a solid than a liquid
Water is not a very good solvent
Answer:
It is the last one.
Explanation:
Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.
A geologist was looking at a new
mineral they found. The mineral
sample was gray, non-metallic, had
density of 3.8 g/mL, and a volume
of 48.3 mL
Of the observed properties listed
below, which is considered to be an
extensive property?
A Gray
B Metallic
C Density
D Volume
Answer:
D. Volume
Explanation:
Properties mentioned in the question;
colour = gray
Nonmetallic
Density = 3.8 g/mL
Volume = 48.3 mL
Of the mentioned, which is extensive ?
Extensive properties are those properties that are proportional to the amount of substance present.
The correct option is D. Volume. The other properties do not change with increasing or decreasing amount of the mineral

State the number of degrees of longitude that separates New York City from Denver, Colorado between these two cities.
Answer:
The number of degrees of longitude that separates New York City from Denver, Colorado is 30.9843 degrees longitude
Explanation:
The longitude of New York City is 74.0060° W
The latitude of New York City is 40.7128° N
The longitude of Denver, Colorado is 104.9903°W
The latitude of Denver Colorado is 39.7392°N
Therefore, the difference the number of degrees of longitude that separates New York City from Denver, Colorado is 104.9903 - 74.0060 = 30.9843°.
Which method of heat transfer is the person in the picture below most worried about?
Radiation
Conduction
Convection
Answer:
Radiation ...........
[tex]\huge\boxed{Conduction}[/tex]
_____________________________________Conduction:Conduction is the transfer of heat when two things come in contact with each other. The energy transfer is from hotter body to the colder body.
x---------------------------------------------x
Fire Walking:There is a trick behind fire-walking. When the coal burns, after sometime there is a layer of ash on the surface of the coal which blocks the radiation. So the transfer of heat is not possible from radiation. Conduction is the only way possible. The person's feet and coal both are poor conductor of heat so if we walk quickly i.e. there is minimal time of contact with the coal, it will just feel a little warm. As the person start walking on the coal, It has to do it quickly, that way Person will feel its sole warming up but it is not that hot because of the layer of ash and poor conductance, after few steps the ash also sticks on to the sole of the person which makes kind of double layers of ash. So the only way for heat transfer is CONDUCTION.

There are 20.8 moles of propanol
Further explanationThe mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³

The previous question is an example of what type of chemical equation?
A.
Synthesis
B.
Decomposition
C.
Single Re-Placement
D.
Double Re-Placement
1, 3, 1, 3
Explanation:
Ga - one on both sides
F - three on both sides
CN - three on both sides
K - three on both sides
But remember that CN was being multiplied by 3 on the right side already, meaning GA(CN)3 didn't mean a coefficient.
Answer:
Double re-placement
The two metals switched dance partners, that means it's a double.

Help please If there are 10 moles of HCl gas occupying 15L at 350°C, what is the pressure? Be sure to show the setup and
the final answer and unit.
Show Your Work
Answer:
P = 34.1 L
Explanation:
Given data:
Number of moles = 10 mol
Volume occupy = 15 L
Temperature = 350°C
Pressure of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
350+273 = 623 K
by putting values,
P×15 L = 10 mol ×0.0821 atm.L/ mol.K ×623 K
P = 511.48atm.L/15L
P = 34.1 L
