Answer: B. a five-carbon chain with a three-carbon branch on the third carbon in the chain

Explanation:

The IUPAC nomenclature of alkanes are given as follows:

Select the longest possible carbon chain.

For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.

A suffix '-ane' is added at the end of the name if all the bonds are single.

If two or more similar alkyl groups are present, then the words 'di', 'tri' 'tetra' and so on are used to specify the number of times these alkyl groups appear in the chain.

Hence, the compound 3-propylpentane will have a five carbon chain as the longest chain and the third carbon bears a substituent with three carbon atoms.

When 24g of magnesium metal is heated in air, 40g of magnesium oxide is produced. What mass of magnesium would be needed in orde
inysia [295]

Answer: 6.1 g

Explanation:

between Mg and MgO theres a 1;1 MOLE RATIO

here's the balanced equation

2Mg + O2 ==> 2MgO

24g of magnesium is approximately 1 mole of magnesium so it produces 40 g of mgo which is also 1 mole of mgo thus 10/40 =0.25 moles of MgO so 0.25 moles of magnesium would be needed  which is approximately 6.1 g

borishaifa [10]

Answer:

cW = 4.2J/g.k

Explanation:

Heat gained = Heat lost

iron(mc∆€) = water(mc∆€)

mi= 100g

ci = 0.449

∆€i= 150-25 = 125

...

mw= 268.5g

cw = ?

∆€w=25-20 = 5

...

100×0.449×125= 268.5×cw×5

5612.5= 1342.5cw

cw = 5612.5/1342.5

cw= 4.18 ~ 4.2J/g.K
