Answer:
The missouri River is a Longesr tributary of the Mississippi River.
B.heterogeneous mixtures
Explanation:
A heterogeneous mixture is a substance containing combination of different ingredients in different ratios.
- Heterogeneous mixtures have their constituents in different phases unlike homogeneous mixtures.
- Solutions are homogeneous of solutes and solvents that are uniformly mixed.
Heterogeneous mixtures can be subdivided into:
Gas liquid mixtures e.g aerated drinks
Liquid- solid mixtures e.g sand-sugar solution
gas solid mixtures e.g smoky air

Answer: B) -4819 kJ
Explanation:
The balanced reaction for combustion of octane is:
To calculate the number of moles, we use the equation:
given mass of octane = 100.0 g
Molar mass of octane = 114.33 g/mol
Putting in the values we get:
According to stoichiometry:
2 moles of octane give heat = -11018 kJ
Thus 0.8747 moles of octane give =
Thus -4819 kJ of heat is released by 100.0 g of octane assuming complete combustion.
The false statement is that the reaction of 17 g of NH3 will produce 27 g of water. (Option D)
<h3>What is a balanced reaction equation?</h3>
A balanced reaction equation is one in which the number of atoms of each element on the right hand side of the equation is equal to the number of atoms of the same element on the left and side of the reaction equation.
The equation of the reaction is 4 NH3 + 5 O2 → 4 NO + 6 H₂O. The number of atoms of each element on both sides are equal.
Hence, the statement that is false from the reaction equation is; "the reaction of 17 g of NH3 will produce 27 g of water".
