There are several types of surfactants, to name two: alkylbenzene sulfonates  or detergents; and lauryl sulfate or foaming agents. 

Alkylbenzene sulfonates are commonly used in the production of detergent soaps, these help clean the dirt from cloths and other materials, it also produces foam. 

Lauryl sulfate or foaming agents are commonly used in the production of dishwashing liquid or handwashing soap.

Which subatomic particles are located in MOST of the space within an atom? A. protons B. neutrons C. electrons
IRISSAK [1]

Answer: -

C. Electrons

Explanation: -

Most of the space in an atom is empty. Through this space the electrons revolve around the centrally placed nucleus.

Inside the nucleus are present the protons and the neutrons. The nucleus size is very small compared to the rest of the atom.

Electrons carry negative charge, protons are positive and neutrons are neutral.

If a container were to have 24 molecules of C5H12 and 24 molecules of O2 initially, how many total molecules (reactants plus pro
frutty [35]

Answer:

81 molecules

Explanation:

The reaction between C5H12 and O2 is a combustion reaction and is represented by the following equation;

C5H12 + 8O2 --> 5CO2 + 6H2O

The ratio of C5H12 to O2 from the above equation is 1 : 8.

Aplying the conditins of the question; 24 molecules each of C5H12 and O2 we have;

3C5H12 + 24O2 --> 15CO2 + 18H2O

This means we have 24 - 3 = 21 molecules of C5H12 that are unreacted.

Total molecules is given as;

3(C5H12) + 24(O2) + 15(CO2) + 18(H2O) + 21(Unreacted C5H12) = 81 molecules

An object has balanced forces acting on it. Which of the following describes the result these balanced forces have on the object
dexar [7]

Answer:

C.It remains at rest or moves at constant speed in the same direction.

Explanation:

First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.

Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at  rest while an object moving will continue to move at the same speed and same direction.

An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.
