They filled 2s before 1s was filled.... 2p is innocent because you shouldn’t be left with an open space when you have a even number... and 3s comes before 2p
Carbon and tungsten are the most common heat resistant elements known. Their melting points are approximately 3400 to 3800 degrees Celsius. Ceramic materials as well are known to be heat resistant inorganic solids. Ceramics are made up of metallic and nonmetallic elements.
Answer:
Explanation:
Reaction of hydrazine is
N2H4 + O2 --> N2 + 2H2O
Mass of hydrazine mole = 14x2 + 1x4 = 32g/Mol
Mass of O2 mole = 16x2 = 32g/Mol
Number of moles in 2.29kg of hydrazine
2290/32=71.56Moles
1mol of hydrazine required to react with 1mol of O2
Amount of O2 required to react with hydrazine
71.56*32=2290
Required O2 amount is exactly the same.
Therefore limiting reactant is hydrazine and excess of 850g of O2 will be in excess.
