Inhibitor
Explanation:
Adding an inhibitor will slow down a chemical reaction. Inhibitors works like a negative catalyst.
The addition of a foreign body can influence the rate of a reaction.
- When a foreign body slows down a reaction, it is called an inhibitor.
- An inhibitor is a negative catalyst that will slow down a reaction.
- Such substances do not allow a reaction to proceed freely and very fast.
- They work in the opposite way a normal catalyst would.
- It is good to know conditions and chemicals that can inhibit a chemical reaction.

Hydrogen can be considered as a clean energy carrier similar to electricity. Hydrogen can be produced from various domestic resources such as renewable energy. ... Power generation,a hydrogen fuel cell generates electricity and gives off heat and water.
5.58 X
Litres is the volume, in liters, occupied by 0.015 molecules of oxygen at STP.
Explanation:
Data given:
molecules of oxygen = 0.015
number of moles of oxygen =?
temperature at STP = 273 K
Pressure at STP = 1 atm
volume = ?
R (gas constant) = 0.08201 L atm/mole K
to convert molecules to moles,
number of moles = 
number of moles = 2.49 x 
Applying the ideal gas law since the oxygen is at STP,
PV = nRT
rearranging the equation:
V = 
putting the values in the rearranged equation:
V = 
V = 5.58 X
Litres.
A solid, a liquid or a gas.
It is B nevermind I thought it was c but it wasn't.
