<span>It depends on what was being combusted.
Supposing the simplest case, where carbon is being burnt:
C + O2 → CO2
(9.0 mol O2) x (1 mol CO2 / 1 mol O2) = 9.0 mol CO2
The answer would be different if the fuel contained any oxygen atoms, for example, alcohol.</span><span>

Answer:
<h2>The answer is 39 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of iron = 5 cm³
density = 7.8 g/cm³
It's mass is
mass = 5 × 7.8
We have the final answer as
<h3>39 g</h3>
Hope this helps you
As a result of temperature regulation within the body of endothermic animals, human bodies are much exposed to the environment than any other endothermic animal which causes human to sweat through their sweat glands and dogs has no sweat glands like that of human
Answer:
7
Explanation:
(Note: for a strong acid and strong base titration the equivalence point is at a pH=7. This is because at this point you have equal moles of added base as acid in the original solution. Therefore at the equivalence point the solution has formed a neutral salt and the pH is 7).
<h3><u>Answer;</u></h3>
C) A convex lens has a thick center and thin edges; a concave lens has a thin center and thicker edges.
<h3><u>Explanation;</u></h3>
- Convex lens refers to the lens which merges the light rays at a particular point, that travels through it, while a concave lens can be identified as the lens which disperses the light rays around, that hits the lenses.
- A convex lens is thicker at the center, as compared to its edges, while a concave lens is thinner at the center as compared to its edges.
- A concave lens is thicker at the edges than in the middle and spreads light rays apart producing an image smaller than the actual object. A convex lens on the other hand, is thinner at the edges and thicker towards the center, that is they are bent towards a central point.
