Mass of CO₂ produced : 58.67 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
CS₂ + 3O₂ -------> CO₂ + 2SO₂
mol of CO₂ based on mol of O₂ as a limiting reactant(CS₂ as an excess reactant)
From the equation, mol ratio of mol CO₂ : mol O₂ = 1 : 3, so mol CO₂ :
mass CO₂ (MW= 44 g/mol) :
The correct answer is (2) density.
An intensive property of a substance is a property that will never change no matter what. Density is a constant and thus an intensive property.

Answer:
A voltaic cell
Explanation:
A voltaic cell is a device which converts chemical energy to electrical energy. The chemical reactions that take place inside the cell causes electrons to flow from anode to cathode hence, electricity is produced. A simple voltaic cell is made by placing two different metals in contact with an electrolyte separated by a salt bridge. The cathode is the negative electrode while the anode is the positive electrode. It is also called a galvanic cell.
In a voltaic cell having a copper/copper solution half cell, reduction occurs at the cathode. Hence, at the cathode copper II ions accept two electrons and become reduced to ordinary metallic copper. This causes the blue colour of the solution to become discharged (fade) as the cell continues to function.
Answer: Diagram C
Explanation:
When a body is under the influence of 2 or more forces, the effect of all forces may be replaced by a unique force (resulting force), with the same result as all original forces.
In case you have different forces with the same direction but different sense, all forces may be substituted by one resulting force, though the module of this resulting force will be equal to the absolute value of the substraction of the modules of the individual forces
For case C, you should check: 8 N (force with right sense) + 4 N (force with right sense) - 4 N (force with left sense) would give us a resulting force of 8 N (with right sense), which will accelerate the body to the right
Answer:
4.55 * 10^23 molecules
Explanation:
This is a conversion problem. We know that one mole has 6.022 *10^23 particles or molecules so we can use this as a conversion factor.
0.755 mol ( 6.022*10^23 molecules/ 1 mol)
=4.55*10^23 molecules
