Answer:
Scientific Law
Explanation: Earth will ALWAYS attract objects to the center of itself because of gravity. This will never be disproven.
Answer:
C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat
Explanation:
There are 6 carbon atoms in reactants to balance you put coefficient 6.
This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.
There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.
If u recheck: 6 C atoms in reactants, 6 C atoms in products.
10 H atoms in reactants, 10 H atoms in products.
17 O atoms in reactants, 17 O atoms in products.
Answer:
C) 11 g
Explanation:
first look to graph , you have x and y
x is mass of Fe
and y is mass of product
if the reaction consumes 2 g of Fe , ( look to x axis , look to 2 )
and go up until the black line touch the line of number 2
and go left and you will see the point become in the middle between 10 and 12
** 12 (11) 10 ***
Good Luck
Answer:
+3
Explanation:
The oxygen all have a -2 oxidation state. (peroxides are exceptions)
The chemical structure is symmetrical. Both carbon are equivalent.
2 (oxidation state of carbon) + 4 (oxidation state of oxygen) = charge of ion.
2 (oxidation state of carbon) + 4 (-2) = -2
oxidation state of carbon = +3
Let (CH2O)n be molecular formula,
(12+1+1+16)n=90.08
30n=90.08
n=3
molecular formula: (CH2O) 3= C3H6O3
