A thermometer is placed in water in order to measure the water 's temperature. What would cause the liquid in the
thermometer to rise?
TUERE
40:
The molecules in the water move closer together.
The molecules in the thermometer's liquid spread apart.
The kinetic energy of the water molecules decreases.
The kinetic energy of the thermometer's liquid molecules decreases.

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.

What is the volume of 2.5 moles of nitrogen gas (n2)at standard temperature and pressure (stp)?
