The time taken for the concentration of N2O to decrease to 32% of its initial concentration is calculated as follows
In(A1/A0)=-Kt
A1= final concentration = 32/100=0.32
A0= initial concentration =100/1000=1
K= constant= 0.76 per sec
time is therefore calculated as follows
In(0.32/1)= -0.76 t
-1.1394 =-0.76t divide both sid3es by -0.76
t is therefore= 1.5 s
The balanced reaction that describes the reaction between butane and oxygen to produce carbon dioxide and water is expressed <span>2C4H10(g)+13O2(g)→10H2O(g)+8CO2(g). For 7.36 g of butane, 11. 4 grams of water is produced. When 72.7 grams of CO2 is produced, 23.9 grams of butane is needed.</span>
Answer:
In an ionic bonds, the metal loses electrons to become a positively charged cation, In which the nonmetal accepts those electrons to become a negatively charged anion.
Explanation:
Explanation:
When fluorine gas reacts with calcium metal at high temperatures then it results into the formation of calcium fluoride.
Since, calcium has 2 extra electrons as its electronic distribution is 2, 8, 8, 2. Whereas each fluorine atom needs one electron to complete its octet.
Therefore, the chemical reaction equation will be as follows.
Answer:
Phosphorus
Explanation:
Lewis Dot Structure is a structural representation of a molecule that shows valence electrons of a molecule.
The element in group 15, period 3 is Phosphorus (P). Phosphorus has an atomic number 15 and valence electrons are 5. So, the lewis structure will show 5 dots around P atom.
