Answer:
A). Calcium chloride dihydrate (CaCl2 * 2H2O) slowly heated in a crucible to become calcium chloride (anhydrous).
Dehyration is a physical process
B). A hydrocarbon such as propane (C3H8) undergoes combustion to power a grill
Combustion is a chemical process.
C). A rock climber’s rope becomes frayed and turns the color of the rocks
This is physical process
D). A dog urinates on an air conditioner coil and the coil becomes corroded
Corrsion is a chemical process.
Explanation:
Answer:
Hexenes + Dioxygen = Carbon Dioxide + Water
The reaction type is combustion.
Its reactants are Hexenes - C6H12 and Dioxygen - O2
its products are Carbon Dioxide - CO2 and Water - H2O
Explanation: This was my yesterdays class
Answer:
Reactants are transformed into products
Explanation:
Chemical reactions are happening everywhere, it may be represented by the following equation:
A(aq) + B(s) ⇒ C(g) + D(l)
The left side represent the reactants that interact to get the products.
In the parenthetycal note is the state of the compound, in this case, aquose solution (aq), solid (s), gas (g), liquid (l)
b. False is the correct answer.
The standard unit for measuring mass is kilogram (kg), which is equal to 10^3 g. In chemistry, we use grams for measuring mass because we just usually use small amounts of stuff, so using grams is more sensible.
Hope this helps~
