Answer:
24.305 to the nearest thousandth.
Explanation:
That is 0.7899*23.985 + 0.10* 24.985+0.1101*25.9825
= 24.305.
Answer:
Aluminum Reacts With Hydrochloric Acid To Produce Aluminum Chloride And Hydrogen Gas. 2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)What Mass Of H2(g) Is Required From The Reaction Of 0.75 G Of Al(s) With Excess Hydrochloric
Answer:
Mg(s)+2HCl(aq)→MgCL2(aq)+H2(g), what mass of hydrogen will be obtained if 100 cm3 of 2.00 mol dm−3 HCl are added to 4.86 g of magnesium?
Explanation:
Moles of metal, = 4.86⋅g24.305⋅g⋅mol−1 = 0.200 mol.
Moles of HCl = 100⋅cm−3×2.00⋅mol⋅dm−3 = 0.200 mol
Clearly, the acid is in deficiency ; i.e. it is the limiting reagent, because the equation above specifies that that 2 equiv of HCl are required for each equiv of metal.
So if 0.200 mol acid react, then (by the stoichiometry), 1/2 this quantity, i.e. 0.100 mol of dihydrogen will evolve.
So, 0.100 mol dihydrogen are evolved; this has a mass of 0.100⋅mol×2.00⋅g⋅mol−1 = ??g.
If 1 mol dihydrogen gas occupies 24.5 dm3 at room temperature and pressure, what will be the VOLUME of gas evolved?

Because the density of the egg is higher than the density of tap water, so it sinks.
Answer:
The p- nitrophenol is more acidic than phenol because the deactivating nature of nitro group and after loosing the protons it makes more resonance stabilization as nitro group is having strong deactivating nature so it attracts electrons towards it.
