Hydrogen peroxide can be prepared by the reaction of barium peroxide with sulfuric acid according to the reaction bao2(s)+h2so4(aq)⟶baso4(s)+h2o2(aq) how many milliliters of 4.00 m h2so4(aq) are needed to react completely with 32.7 g bao2(s)?

The answer to your question is: Volume = 15.2 ml

Explanation:

Data

H2SO4 4M  = ?

BaO2          = 32.7 g

                        BaO2(s)  +  H2SO4(aq)  ⟶  BaSO4(s)  +  H2O2(aq)

MW BaO2 = 137 + 32 = 169 g

MW H2SO4 = 2 + 32 + 64 = 98 g

                       169 g of BaO2  98 g of H2SO4

                        32.7 g of BaO2    x

                        x = (32.7 x 98)/ 169

                        x = 18.99 ≈ 19 g of H2SO4

Density of H2SO4 = 1.25 g/lml

Volume = mass / density

Volume = 19 g / 1.25 g/ml

Volume = 15.2 ml

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
