The mass of oxygen gas is released in the reaction of decomposition of magnesium oxide 6.4 grams
calculation
mass of oxygen=mass of magnesium oxide -mass of magnesium produced
that is 16.12-9.72=6.4 grams
Answer:
It won't work as well. You can try though, it won't hurt anything
Answer:
A, D,E
Explanation:
I think thats right. Cuz losing electrons makes you cation, gaining electron by a neutral atom makes you negative, and giving up electrons is synonymous to acting like a "metal"
Answer:
The answer to your question is: d
Explanation:
Electron configuration of Carbon.
Atomic number of carbon = 6
a) 1s²2s²2p¹ Number of electrons = 5, This is the electron configuration of Boron.
b) 1s²2s²2p⁴ Number of electrons = 8. This is the electron configuration of oxygen.
c) 1s²2s²p² Number of electrons = 6. This is the electron configuration of carbon. But I think is lacking a number two before p.
d) 1s²2s²2p² Number of electrons 6, This is the correct electron configuration of carbon.
<span>4.200 calories. The formula is rise in heat (H) = the specific heat capacity (c) * rise in heat in degrees Fahrenheit (T) and volume of liquid (m) . H= cTm. Water, the typical comparison, has a specific heat capacity of 1. So to raise the Fahrenheit temperature of 105 grams of water 40 degrees, you multiply 105 * 40 * 1 = 4,200.</span>
