Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Next, we compute the reacting moles of each reactants:
Then, as magnesium and hydrohloric acid are in a 1:2 molar ratio 0.153 moles of magnesium will completely react with 0.306 moles of hydrochloric acid yet we only have 0.144 moles, therefore, limiting reactant is hydrochloric acid. Thus, we compute the produced moles of hydrogen:
Finally, we use the ideal gas equation with T=298K and 1atm (STP conditions) to compute the liters of hydrogen gas:
Best regards.
<span>A PRECIPITATE is a solid that forms inside of a mixture.
When we add lemon juice to milk, the lemon juice causes lumps to form inside of the milk. SOLID lumps.
We call them "curds." So, we end up with SOLID curds, formed inside of liquid whey.
if that doesn't help its B</span>
A process called fission which generates heat to produce steam, which is used by a turbine generator to generate electricity.
Exothermic reaction = the term exothermic process describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity,
Endothermic reaction = An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
