Answer:
Tetrahedral molecules are normally spy hybridized.
Explanation:
Answer:
6.76 moles.
Explanation:
2CO(g)+O2 (g) =2CO2(g)
When 2 CO mols were reacted with excess O2 then 2 mols of CO2 is created.
Therefore if 6.76 moles reacted, same number of CO2 will be created.
Chemical reactions can be identified when there is a change in color, energy is produced, change in odor, or if new substance forms.
Answer:
The correct option is;
X, W, Y, Z
Explanation:
The parameters given are;
Spring (S), Spring Constant (N/m)
W, 24
X, 35
Y, 22
Z, 15
The equation for elastic potential energy,
, is 
The above equation can also be written as 
Where:
k = The spring constant in (N/m)
x = The spring extension
Therefore, since the elastic potential energy,
, of the spring is directly proportional to the spring constant, k, we have the springs with higher spring constant will have higher elastic potential energy,
, therefore the correct order is as follows;
X > W > Y > Z
