Answer:
The answer is C. rolling
Explanation:
I know this bc its the only reasonable answer since friction occurs when dealing with with solids and what is food? a solid
lol jp i dont know if this is right.
Answer:
Change in plate tectonic leads to change in earth surfaces.
Plate tectonics have changed Earth’s surface over time because the earth surface is placed on these plate tectonics. Earth's outer surface is divided into various plates that slowly move over the mantle which changes Earth's surface over time by merging and separating of landmasses that turn into continents.
The movement of tectonic plates is responsible for the creation of landforms such as volcanoes and ridges. Some volcanoes are formed when the tectonic plates pull apart from one another whereas some volcanoes are produced when a tectonic plate slides over one another so we can conclude that change in plate tectonic leads to change in earth land forms.

Answer:
Explanation:
Given that:-
Mass of the hydrated salt = 7.028 g
Mass of the anhydrous salt = 3.100 g
Mass of water eliminated = Mass of the hydrated salt - Mass of the anhydrous salt = 7.028 - 3.100 g = 3.928 g
<u>Moles of water:
</u>
Mass of water = 3.928 g
Molar mass of 
= 18 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
<u>Moles of anhydrous salt:
</u>
Amount = 3.100 g
Molar mass of 
= 142.04 g/mol
Thus, moles are:
The simplest ratio of the two are:
=0.02182 : 0.2212 = 1 : 10
<u>Hence, the formula for hydrate is:- </u>
A precipitate will form since BaSO₄ is insoluble in water.
