Consider the chemical equation for the combustion of sugar. _C6H12O6(s) + _O2(g) Right arrow. _CO2(g) + _H2O(l) Which sequence of coefficients should be placed in the blanks to balance this equation?
a. 1,6,6,6
b. 6,1,6,1
c. 3,3,3,6
d. 1,3,3,6

c.

explanation:

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
