Answer: 0.374 mol CO2
Explanation:
We can calculate the number of moles of CO, n, required to produce the specified quantity of heat. This is done by dividing the required released heat, q, by the enthalpy of formation per unit mole of the substance, , based on the chemical equation, such that:
Therefore, 0.374 mol of CO2 must be reacted in order to produce 147 kJ of energy?
Answer:
Pencil is an element and a heterogeneous mixture
Explanation:
Extensive properties depend on the amount of substance. The volume of a sample is an extensive property: 1000 grams of water takes up more volume than 10 grams of water. Mass is also an extensive property.
The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.
<h3>What is radon gas?</h3>
