An example of a heterogeneous catalyst is a catalytic converter. A catalytic converter is an emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (oxydation or reduction).
Eight, since it has eight valence electrons.
Answer:
Explanation:
There are 118 different known <em>elements</em>.
Each element is identified by the number of protons and it is called the atomic number. For instance, the atomic number of hydrogen is 1, every hydrogen atom has one proton; the atomic number of oxygen is 8, every oxygen atom has 8 protons; the atomic number of carbon is 6, every carbon atom has 6 protons.
There are not two different elements with the same atomic number (number of protons).
The 118 known elements are listed in the periodict table in groups (columns) and periods (rows) in increasing order of atomic number (number of protons).
So, by counting the number of protons of an atom, chemists can tell the element to which the atom belong.
They have high electron affinity
Answer:
1C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l)
Explanation:
In general equation combustions where all carbon produce CO₂ and all hydrogen H₂O we must begin the balance with these two species:
_C₆H₁₂O₆(s) + _O₂(g) → _CO₂(g) + _H₂O(l)
If sugar is 1, CO₂ and H₂O must be:
1C₆H₁₂O₆(s) + _O₂(g) → 6CO₂(g) + 6H₂O(l)
Thus, C and H are balanced. In the right side we have 12 oxygen from CO₂ + 6 oxygen from H₂O = 18 oxygen
In the left there are 6, thus, O₂ must provide 12 oxygens, thus:
<h3>
1C₆H₁₂O₆(s) +
6O₂(g) →
6CO₂(g) +
6H₂O(l)</h3>
And this is the balanced reaction
