Carbohydrates, more commonly known as sugars, are made up of carbon, oxygen, and hydrogen atoms. the smallest unit of a carbohyd

rate is a monosaccharide. two monosaccharides make up a disaccharide, and many monosaccharides make up a polysaccharide. disaccharides and polysaccharides can be hydrolyzed back into the individual monosaccharide units.

Methanol can be produced by the following reaction: CO(g) 2 H2(g) CH3OH(g). How is the rate of disappearance of hydrogen gas rel
belka [17]

Answer:

r_{H_2}=-2r_{CH_3OH}

Explanation:

Hello!

In this case, for the reaction:

CO(g)+ 2 H_2(g) \rightarrow CH_3OH(g)

In such a way, via the rate proportions, that is written considering the stoichiometric coefficients, we obtain:

\frac{1}{-1} r_{CO}=\frac{1}{-2} r_{H_2}=\frac{1}{1} r_{CH_3OH}

Whereas the reactants, CO and H2 have negative stoichiometric coefficients; therefore the rate of disappearance of hydrogen gas is related to the rate of appearance of methanol as shown below:

\frac{1}{-2} r_{H_2}=\frac{1}{1} r_{CH_3OH}\\\\r_{H_2}=\frac{-2}{1} r_{CH_3OH}\\\\r_{H_2}=-2r_{CH_3OH}

Which means that the rate of disappearance of hydrogen gas is negative and the rate of appearance of methanol is positive.

Regards!

What is the ratio of carbon to oxygen in the following balanced equation: 2C + O2–&gt; 2CO
Morgarella [4.7K]

Answer:

The ratio is 2:1, that is 2mol C  / 1mol O2

Explanation:

First check to see if the equation is balanced. It is so now let's find the ratio.

The ratio is the stoichiomeric coefficient of the element or compound.

Carbon : Oxygen

2C : 1 O2   , so 2:1 ..

A box has dimensions of 14 inches long, 1.5 feet wide, and 7 inches high. What is the volume of the box?
Brilliant_brown [7]

Answer:

V = 4480.56 cm3

Explanation:

Data Given

Length “l” = 14 inches

Hight “h” = 7 inches

Width “w” = 1.5 feet

Volume= “V”

Solution:

Formula to Use

V= l . w. h

Note: here we have to values in the same unit

So the Length “l” and Hight “h” both are in inches but the width is in feet

So we changes the feet into inches

1 foot = 12 inches

1.5 feet = 12 x 1.5

1.5 feet = 18 inches

So width is 18 inches

Now putting the values in formula

V = l . w. h

V = 14 . 18 . 7

V = 1764 inch

You can convert inches to cm

1 inch = 2.54 cm

So 1764 inches = 2.54 x 1764

1764 inches = 4480.56 cm3

So

V = 4480.56 cm3
