Answer:
Balance the following equations. Enter 1 as a coefficient for reactants and products which have no coefficient.
(NH4)2Cr2O7(s) _> Cr2O3(s)+N2(g)+H2O(g)
Explanation:
Volume of a cube = mass/density
mass=100grams
density=1g/cm^3
volume is therefore= 100grams / 1gram/cm^3= 100cm^3
The answer is 0.57 atmospheres.
Answer:
B.
Explanation:
Some of the elements of the third-period and periods below can have expanded octet because they have d- sub-level.
