Answer:

Follows are the solution to this question:

Explanation:

Please find the image file of the chemical reaction in the attachment:

In a water medium, the CH3- type CH 3Li is a heavy nucleophile that attacks the carbonyl carbon atom to form the alkoxide ion, which will then be protonated to form alcohol.

If one gram of sulphur dioxide contains x molecules what will be the number of molecules in 1g of methane

evablogger [386]

The ratio of molecules in sulphur dioxide and methane will be the same as the ratio of their moles. So, first of all we should find out the number of moles of sulphur dioxide in 1 gram of sulphur dioxide in 1 gram of sulphur dioxide, and the number of moles of methane in 1 gram of methane. This can be done as follows :

(i) The molecular formula of sulphur dioxide is $SO_{2}$

So, $1$ mole of $SO_{2}$ = $Mass$ $of$ $2'O'$

$=32+2*16$

$= 64$ grams

Now, $64g$ of sulphur dioxide $= 1$ mole

So, $1g$ of sulphur dioxide = $\frac{1}{64}$ mole

Thus, we have $\frac{1}{64}$ mole of sulphur dioxide and it contains molecules in it. Now, since equal moles of all the substance contain equal number of molecules, therefore, $\frac{1}{64}$ mole of methane will also contain x molecules of methane.

(ii) Molecular formula of methan is $CH_{4}$

So, 1 mole of $CH_{4}$ = Mass of C + Mass of 4 H

$=12+4*12$

Now, 16g of methane = 1 mole

So, 1 g of mathane = $\frac{1}{16}$ mole

We know that:

$\frac{1}{64}$ mole of methane contains = x molecules

So, $\frac{1}{16}$ mole of contains will contain = $\frac{x*64}{16}$ molecules

= $4x$ molecules

A food company produces raspberry coulis as a topping for its best-selling line, double strength chocolate mousse pie. Fresh ras

rewona [7]

Answer:

5357.1429kg per week

2142.8571 kg per week

Explanation:

Given that :

Fresh Raspberries :

5% = seeds

20% = pulp solids

75% = water

Raspberry : Sugar = 3.5 : 1

Water content = 35%

Coulis produced per day = 0.5 tonnes

Mass of Raspberry produced per week :

Mass is measured in kg;

1 tonne = 1000kg

0.5 tonne = (1000/2) kg = 500kg

Mass of Coulis produced per week = 500kg * 7 = 3500kg

Coulis contains 35% water, Raspberry required 75% water :

(3500 / 35) * 75 = 7500kg

Raspberry : Sugar ratio = 3.5 : 1

Mass of Raspberry :

[7500 - (1 /3.5) * 7500]

7500 - 2142.8571

= 5357.1429kg per week

Sugar required per week:

(1/3.5) * 7500kg

= 2142.8571 kg per week

C.)

Sugar content in coulis :

If you pour equal amounts of scalding hot water into different metallic cups of equal temperature, which cup will heat up the mo

Zanzabum

Answer: The cup with the highest Thermal Conductivity will heat up the most.

Explanation:

The Thermal Conductivity of a metal is its capacity of transmitting heat from one point to other, under steady conditions . The higher the thermal conductivity, then, it better conducts it.
