The answer is A. PCl15 because a covalent bond is formed by two nonmetals bonding.
Answer:
1.3 meters
Explanation: use newton third law equation.
To solve the amount heat that was added or lost in the surrounding, use the formula:
q = m cp dt
where q is the heat
m is the mass of the substance
cp is the specific heat of the subtance
dt is the change in temperature ( t2 - t1 )
just substitute the given value
Answer:
hydrogen bonds between water molecules
Explanation:
The hydrogen bonds between water molecules conditions the bulk of its physical property most especially its relatively high boiling point. The hydrogen bond results from the attraction between the oxygen of a water molecule and the hydrogen of another water molecule. The more electronegative oxygen atom causes a distortion and the attraction leads to a strong intermolecular bond between atoms of the water molecules.
Hydrogen bond is a very strong bond and it is responsible for the physical properties of water.
the rate law should be k[S2O8^-2]
