Answer:
=0.475M
Explanation:
Molarity=(moles of solute))/(litres of solution)
So, molarity in this question:
=(0.19 moles of sodium carbonate)/(0.4 L of solution)
=0.475M

Light would be more consistent being made up of particles rather than waves.
Electric Potential is the work done per unit charge in order to bring the charge from infinity to a point in electric field while Electric potential difference is the Potential developed while moving a charge from one point to another in the field itself.
According to Le Chatelier's Principle, to increase the rate of the forward reaction we add more of the reactants to encourage more collisions and production of more products. If it is endothermic, more heat should be added. If it is endothermic, more heat should be released from the system.
Answer:
yes they are
Explanation:
if you are heating up glass i believe not, unless you want to break the glass. Making glass go from high to low or low to high tempuatures quickly will cause it to break. How ever metal will be stronger as long as you dont bend it.
