<span>A bond between two atoms in which the shared electron or electrons are equally likely to be found near each atom is called a non Polar Covalent Bond.
Explanation:
As we know atoms react in order to gain stability. Now, the bonding is done by several ways. Among these ways one is the mutual sharing of electrons between two atoms. Neither one completely accepts nor donate the electron instead they share it equally. If this sharing is purely equal then the bond formed is non polar in nature (like bonds between similar atoms), on the other hand if this sharing is not equal then one atom will get partial positive (less electron density) and other will get partial negative (more electron density) charge like in HCl.</span>
Answer: -
4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O
Explanation: -
The given equation is
C₂H₅ + O₂ → CO₂ + H₂O
Balancing for H,
2C₂H₅ + O₂ → CO₂ + 5H₂O
Balancing for C
2C₂H₅ + O₂ → 4CO₂ + 5H₂O
Now right hand side we are getting 13 O which is an odd number.
In order to balance O, we first try to even out the number of O on right side by multiplying whole equation by 2.
4C₂H₅ + 2O₂ → 8CO₂ + 10H₂O
Now balancing for O
4C₂H₅ + 13 O₂ → 8 CO₂ + 10 H₂O
False, metamorphic rocks are formed under pressure, is crystals are then formed into layers
Using the ideal gas law PV =nRTPV=nRT , we find that the pressure will be P =\frac{nRT}{V}P=

nRT
. Then, we'll substitute and find the pressure, using T = -25 °C = 248.15 K and R = 0.0821 \frac{atm\cdot L}{mol \cdot K}

:
P =\frac{nRT}{V} = \frac{(0.33\,\cancel{mol})(0.0821\frac{atm\cdot \cancel{L}}{\cancel{mol \cdot K}})(248.15\,\cancel{K})}{15.0\,\cancel{L}} = 0.4482\,atmP=
