Answer:
5.90 moles of ethane, C₂H₆, is burned in an excess of oxygen to produce 11.8 moles of CO₂.
Explanation:
To answer the question, we examine the chemical reaction as follows
2C₂H₆ ( g ) + 7O₂ ( g ) ⟶ 4CO₂ ( g ) + 6H₂O ( g )
From the chemical reaction it is seen that 2 moles of ethane, C₂H₆, is required to produce 4 moles of CO₂
This means that 1 mole of C₂H₆, is required to produce 2 moles of CO₂
Since we are asked to find out how many moles of CO 2 are produced when 5.90 moles of ethane is burned in an excess of oxygen and we already know that 1 mole of C₂H₆, is required to produce 2 moles of CO₂, we multiply both the 1 mole of C₂H₆ and the 2 moles of CO₂ by 5.90 to obtain;
(5.90 × 1 mole) of C₂H₆ is required to produce (5.90× 2 moles) of CO₂ or
5.90 moles of C₂H₆ is required to produce 11.8 moles of CO₂.
Answer:
energy that is transmitted in the form of electromagnetic waves.
Explanation:
Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum.
Sorry my guy no idea try googling
Answer:
Explanation:
If the fission is induced by two neutrons, the unbalanced equation is
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation .
Balancing the superscripts, we get
2 + 239 = 89 + 149 + x
241 = 238 + x
x = 3
The balanced nuclear equation is
