Explanation:

Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5. The pentahydrate (x = 5) is the most common form. Older names for this compound include blue vitriol, bluestone,[9] vitriol of copper,[10] and Roman vitriol.[11]

What is the reaction type of 3ZnS+ 2AlP = 1Zn3P2 + 1Al2S3 ?

adelina 88 [10]

Answer: double displacement

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The balanced chemical equation is:

$3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3$

Thus as ions get exchanged , it is double displacement reaction.

The heat of combustion of butane is 2877.5 kJ/mol how much heat in calories will be produced in the combustion of 100.0 g of but

Oliga [24]

Answer:

The answer is 1,185,000 cal or 1,185 kcal

Explanation:

We convert the weight of butane (C₄H₁₀, MW = 58) to mole

n = m/M = 100.0 / 58 = 1.724 mol

The heat of combustion of 100.0 g or 1.724 mol of butane is

H(kJ) = 1.724 mol x 2,877.5 kJ/mol = 4,960.8 kJ

Then we convert the unit to calories

H(cal) = 4,960.8 kJ / 4.184 kJ/kcal = 1,185 kcal = 1,185,000 cal

How many lithium ions are present in 30.0 ml of 0.600 m li2co3 solution?

Nikolay [14]

First; use the relationship of molarity and moles/liter to find the moles of the solution.
so 0.600M ×0.030L = 0.018 moles
Then use the mole to mole ratio of lithium to lithium carbonate
0.18 × (2 Li ÷1 Li2CO3) = 0.036
and then multiply by Avogadro's number to find the ions of lithium
0.036 moles × (6.022×10^{23} ) = 2.167 ×10∧22 ions Li

What does a mole of iron weigh

r-ruslan [8.4K]

As the atomic mass of iron is 55.847u

We say that it is the mass of one mole of iron.

By formula it can be find by

No.of mole=mass in g/molar mass

Mass in gram = no.of mole x molar mass

No.of mole =1

Molar mass = 55.847g

Mass in gram = 1x55.847

= 55.847g of Fe
