Answer: Potassium perchlorate
Explanation:
Answer:
Reaction rates are not related to spontaneity
Explanation:
A spontaneous reaction is one which occurs on its own or on some activation. Non spontaneous reactions are those which do not occur on their own and thus constant energy must be supplied to make them happen.
Reaction rate is dependent on the amount of reactants and the activation energy and not on the spontaneity of the reaction. Reactions with high activation energy are slow and reactions with low activation energy are fast.
The substance is followed by H2O
Answer:
It is false :l
Explanation:
Pahoehoe is a smooth and continuous lava crust. Pahoehoe forms when the effusion rate is low and consequently the velocity of lava flow is slow. Pahoehoe lava flow is usually at least 10 times slower than typical aa lava flow.

Answer : The vapor pressure of water at 
is 1.01 atm.
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = ?
= final pressure = 750 torr = 0.987 atm (1 atm = 760 torr)
= initial volume = 1.95 L
= final volume = 2.00 L
Now put all the given values in the above equation, we get:
Therefore, the vapor pressure of water at is 1.01 atm.
