The answer is b. 4.2 mole. The balanced reaction formula is 2LiOH + H2SO4 -->Li2SO4 + 2H2O. And the ratio of mole number of the reactants is the same as the ratio of coefficients.
Molarity = moles of solute / liters of solution
M = 0.5 / 0.05
M = 10.0 mol/L⁻¹
hope this helps!
<span>According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of
products of chemical reaction increase, if:</span>
<span>1) increase temperature, because this endothermic reaction.</span>
<span>2) increase concentration of reactant.</span>
<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>

Answer:
The term conclusion best illustrates the given statement.
Explanation:
Conclusion refers to a decision or judgment that can be acquired by reasoning. From the observation mentioned in the given table:
1. The steel, aluminum, and bronze took 27, 45 and 80 seconds to dissolve small section of wax, this signifies that more time will be needed by them to transfer heat to the food while cooking. Thus, food will take more time to cook in them.
2. Copper consumed less time, that is, 15 seconds to melt the section of wax than the other metal pots, which signifies that it is a good conductor of heat than the others. Thus, the copper pot would be good for cooking food briskly.
After evaluating the results and observations in an experiment, the conclusion was made that pots made of copper are best for cooking foods.
Answer:
187.407g
Explanation:
Moles of solute = Molarity × Liters of solution
Multiply 0.60 M by 1.50L:
0.60 mol/ 1L×1.50L=0.9 mol
To obtain the mass of solute, we will need to the molar mass of BaCl2, which is 208.23g/mol:
Finally, multiply the number of moles by208.23g /mol
0.9mol×208.23g/1mol =187.407g
Boom, you have a mass of:
187.407g
