Answer:
CH₄(g) + 2O₂(g) ---> 1CO₂(g) + 2H₂O(g)
Explanation:
any combustion of a hydrocarbon equation is in form:
CₓHₐ(g) + BO₂(g) ---> YCO₂(g) + ZH₂O(g), where x,a,b,y,z are all whole number positive integers
there will be 1 CO₂ to 2 H₂O, since there is 1 C to 4 H in CH₄; it is not 1:4 since 2 H is needed in H₂O
CH₄(g) + _O₂(g) ---> 1CO₂ + 2H₂O
there is 4 total O on products side, which can make 2O₂
CH₄(g) + 2O₂(g) ---> 1CO₂(g) + 2H₂O(g)
Answer:
B
Explanation:
Because a ball falling down is a good strong force
Answer:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
In order to answer this question we must look at the image which I have attached.
The red atoms refer to oxygen atoms, the grey atoms are carbon atoms and the blue atoms are nitrogen. Therefore, the equation from the image suggests:
2CO + 2NO → 2CO₂ + N₂
Looking closely at the options given, several of them could be eliminated immediately since they are not balanced equations like B, C and E. Therefore, only A or D could be the answers.
The answer is option

Subshell S is likely to be filled before the rest of the subshells
