To answer this question, you need to know the chemical equation for making glucose. It should be look like this
C6H12O6<span>(s) + 6O2(g) -->6CO2(g) + 6H2O(g)
In the equation, the amount of glucose (</span>C6H12O6) is 1 and the amount of oxygen(O2) is 6. But the equation ratio is using moles as a unit. A mole of glucose will weight 180g but a mole of oxygen weight 32g.
Then, the amount of oxygen forms would be: 6/1 * (15.90g/180g) * 32g= 16.96 grams
Mass of carbon = 5.00 * 12.0 / (12.0 + 16.0*2)
= 1.36g
no. of moles of C = 1.36 * 12.0 = 16.3 moles
Answer:first one is chemical change and the second one is chemical reaction that sh be right.
Explanation:
Answer:-
If an element has 3 or more valence electrons then the element belongs to p block of the periodic table. For p block elements the group number is found out by adding the number of electrons in valence shell + 10.
The reason for this is because in the middle of the periodic table there are the d block elements ranging from group 3 to group 12 a total of 10 groups in between elements having 2 valence electrons and 3 valence electrons
Answer:
As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder. Relative sound intensities are often given in units named decibels (dB).
