Calculate the mass of ethyl alcohol required to prepare 540 grams of C4H6, if the reaction follows the scheme:

kkurt [141]

Answer:

Explanation:

2C₂H₅OH = C₄H₆ + 2H₂O + H₂

2 mole 1 mole

molecular weight of ethyl alcohol

mol weight of C₂H₅OH = 46 gm

mol weight of C₄H₆ 54 gm

540 gm of C₄H₆ = 10 mole

10 mole of C₄H₆ will require 20 mol of ethyl alcohol .

20 mole of ethyl alcohol = 20 x 46

= 920 gm

ethyl alcohol required = 920 gm .

How many grams of lithium hypochlorite (LiClO) are there in 0.594 moles?

Flauer [41]

Answer : The mass of lithium hypochlorite are, 34.7 grams.

Explanation : Given,

Moles of $LiClO$ = 0.594 g

Molar mass of $LiClO$ = 58.4 g/mol

Expression used :

$\text{ Mass of }LiClO=\text{ Moles of }LiClO\times \text{ Molar mass of }LiClO$

Now put all the given values in this expression, we get:

$\text{ Mass of }LiClO=(0.594moles)\times (58.4g/mole)$

$\text{ Mass of }LiClO=34.7g$

Therefore, the mass of lithium hypochlorite are, 34.7 grams.

_______ is the classic structural formula for all the addictive narcotics

oee [108]

The answer to this statement is codein. Codein, or 3-Methylmorphine by its IUPAC name, is an opiate used as pain reliever and suppressor of coughs. Its structural formula is shown in the picture. The patient's dosage of these narcotics should be strictly prescribed by the doctor. When patients take this, they feel euphoria, hence, they tend to crave for that feeling once it's gone. Too much dosage of this drug would lead to addiction. Examples of drugs with this structural formula are Cotabflu, Nalex AC, T-Koff and Pediatuss.
