Answer:

Explanation:
Hello!
In this case, for the reaction:

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

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:

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

Answer:
2,7,4,6
Explanation:
atoms at the left side should be equal to that of right for an equation to be balanced. so the answer is the final one
It is A Liquid not A solid.
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 ..
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
