Given :

Two chemicals Cu_2O(s) and CuO(s) .

To Find :

Are these substances same or different explain.

Solution :

It might seem that the difference is none because the atoms used in the molecules are same but in different proportion .

But , their is a lot of difference between them .

The change in configuration impacts a lot in physical as well as chemical properties .

For ex :

Cu_2O is red powder while CuO is black powder .

Cu_2O is fungicide while CuO is used in batteries .

Hence , this the required solution .

What is the average kinetic energy of 1 mole of a gas at 125 kelvin? (R = 8.314 J/K-mol)
Nookie1986 [14]
The average kinetic energy of a mole of gas can be determined through the equation KE= 1.5 nRT where R is the gas constant equal to <span>8.314 J/K-mol and T is temperature, The temperature for this problem is 125 Kelvin and n is equal to 1 mole. KE then is equal to 1558.88 Joules.</span>

What is the maximum mass of s8 that can be produced by combining 87.0 g of each reactant? 8so2+16h2s=3s8+16h20?
zhenek [66]
The balanced chemical reaction is expressed as:

<span>8SO2 + 16H2S = 3S8 + 16H2O

We are given the initial amount of the reactants. From there, we determine the limiting reactant. We do as follows:

87.0 g SO2 ( 1 mol / 64.07 g ) = 1.36 mol SO2 ( 16 mol H2S / 8 mol SO2 ) = 2.72 mol H2S
87.0 g H2S ( 1 mol / 34.08 g ) = 2.55 mol H2S ( 8 mol SO2 / 16 mol H2S ) = 1.28 mol SO2

Therefore, the limiting reactant would be H2S. We calculate the maximum amount of S8 that can be produced from the amount of H2S.

2.55 mol H2S ( 3 mol S8 / 16 mol H2S ) ( 256.48 g / 1 mol ) = 122.63 g S8</span>

1. How many covalent bonds are expected to form from phosphorus in order to obey the octet rule?
Grace [21]
To satisfy the octet rule, there has to be eight electrons in phosphorus's outermost shell. Phosphorus has five electrons in its valence shell, fluorine has seven. This means that phosphorus would have to bond to three fluorine atoms in order to have eight electrons in its valence shell without breaking the octet rule in any one of the fluorine atoms.

Silicon has four electrons in its outer energy level. What type of bond is silicon mostly likely to form with other elements? Ex
RideAnS [48]
Since it has 4 electrons, it needs only 4 more to be stable. Therefore, it would share electrons, which is a covalent bond. 

Answer: Covalent bond
