Carbon can form a maximum of 4 covalent bonds because it has 4 valence electrons i.e. 4 outer electrons.
Answer:
molecular weight of H2O2 or grams. This compound is also known as Hydrogen Peroxide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2O2, or 34.01468 grams.
1 grams H2O2 is equal to 0.029399071224542 mole.
1 grams H2O2 to mol = 0.0294 mol
10 grams H2O2 to mol = 0.29399 mol
20 grams H2O2 to mol = 0.58798 mol
30 grams H2O2 to mol = 0.88197 mol
40 grams H2O2 to mol = 1.17596 mol
50 grams H2O2 to mol = 1.46995 mol
100 grams H2O2 to mol = 2.93991 mol
200 grams H2O2 to mol = 5.87981 mol
Answer:
Explanation:
Mole = No. Of atom/Avogadro const
Avogadro constant= 6.02×10^23
Mass of Cu =22g
Molar mass of Cu =63.5g/mol
Mole = mass/molar mass
Mole = 22/63.5
Mole = 0.346
No. Of atom=mloe ×avogadro conts
No. Of atom = 0.346 × 6.02×10^23
No. Of atom = 2.09 × 10^23atoms
Answer:
Then pressure will double
Explanation:
PV = nRT
P = nRT / V
If all other variables are kept constant, P will be proportional to n i.e
P1 / n1 = P2 / n2
n = 1
P1 = P
n2 = 2
P2 =?
P1 / n1 = P2 / n2
P /1 = P2/2
Cross multiply
P2 = 2P
Therefore, if an additional 1mole of the gas is added, the pressure will double
The balanced equation is:
C3H8 + 5O2 > 3CO2 + 4H2O.
It takes 5 molecules of O2
