Answer:

i just had a test on this with 2 attempts and got it wrong on both but i do know that the answer is not...

the steepness of the models hillside

or

the rate of erosion on the hills

so the answer is either...

the amount of water sprayed on the hills

or

the type of material used to construct the model hills

but i think its the amount of water sprayed on the hills...i hope i helped a lil ;)

A sample of gas occupies 7.80 liters at 425°C? What will be the volume of the gas at 35°C if the pressure does not change?
Ksenya-84 [330]
V₁/T₁=V₂/T₂

T₁=425+273.15=698.15 K
T₂=35+273.15=308.15 K

V₂=V₁T₂/T₁

V₂=7.80*308.15/698.15=3.44 L

3.44 liters

How does the number of valence electrons determine the type and number of bonds an element forms?​
Advocard [28]
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... Nonmetals tend to attract additional valence electrons to form either ionic or covalent bonds.

Each atom consists of a central nucleus and several shells that contain electrons. The outermost electrons are called valence el
Eduardwww [97]

Explanation:

Not only did outermost electron determine the valence electron, but also <em>periodic</em><em> </em><em>table</em><em>.</em><em> </em>whatever group they fall into in periodic table each valence electrons present in a particular atom e.g K and Ca belong to group 1 and 2 respectively and k has 1 and Ca have 2 in each outermost electron

Besides hydrogen and oxygen what is required to produce the chemical reaction that yields water
timurjin [86]
Hey there! Hello!

In order for water to be formed, or for any reaction to occur, there needs to be something that splits the current bonds of hydrogen and oxygen up. In this case, some sort of activation energy is required. 

Hydrogen and oxygen are not found as single molecules in nature. They're found as 2 molecules linked together, as H2 and O2. An activation energy, such as heat, or some sort of catalyst needs to be used in order to split the two molecules up and make them link with one another. 

What happens afterwards is a chemical reaction that involves the valence electrons of oxygen (which has 6 on the outermost shell) and hydrogen (which has two on the outermost shell). The oxygen wants to have an octet (8 valence electrons) total, so it shares with the hydrogen, which is already satisfied with it's two valence electrons (according to the nature of hydrogen). 

But because there has to be a total of four molecules involved, two molecules of water are going to be produced as a result. 

2H+2O=2H20

Hope this helped you out! Feel free to ask me any additional questions if you need further clarification. :-)
