Answer:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).
Explanation:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
2H₂O(g) → 2H₂O(l)
- To add the two equations: we omit H₂O(g) that is formed by 2 moles in the product side of the first equation and consumed by 2 moles from the reactants side in the second equation
- So, the overall chemical equation is obtained by combining these intermediate equations is:
<em>CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).</em>
<em></em>
The answer would be A. which says the emitter- base junction must be forward biased, and the collector- base junction must be reverse biased.
a) double-displacement
Explanation:
We have the following chemical reaction:
Na₂S (aq) + Cd(NO₃)₂ (aq) → CdS (s) + 2 NaNO₃ (aq)
where:
(aq) - aqueous
(s) - solid
This chemical reaction is a double-displacement reaction because the reactant exchange atoms or group of atoms between themselves. The reaction is driven to right by the formation of the precipitate. The general representation for this kind of reaction is: AB + CD → AC + BD
In a synthesis reaction two elements will combine to form a compound.
2 H₂ + O₂ → 2 H₂O
In a single-displacement reaction an atom or group of atoms from a compound is displaced by another atoms. The general representation for this kind of reaction is: A + BC → B + AC

Answer:
0.5 or .5
Explanation:
The answer to number 3 is 0.5 and here's why:
you have to divide the voltage by the resistance right so you would divide 1.5 by 3 to get 0.5
