Glycolysis--The breakdown of a glucose molecule into two three-carbon pieces called pyruvate. You will notice that very little ATP is produced in this step and no oxygen is required. ... This step is also where other molecules besides glucose may be fed into the cell respiration<span> process, especially lipids.</span>
Answer:
= <em>3</em><em>7</em><em> </em><em>g</em>
Explanation:
H₂SO₄ + 2NaOH ----> Na₂SO₄ + 2H₂O
2 moles of NaOH react with 1 mole of H₂SO₄
0.75 moles of NaOH will react with (0.75 / 2)×1
= 0.375 moles of H₂SO₄.
Formular mass of H₂SO₄ = (1×2)+32+(16×4) = 98g
1 mole of H₂SO₄ weighs 98g
0.375 moles of H₂SO₄ will weigh ( 0.375×98)g
= 36.7g = 37g of H₂SO₄
Answer:
d.the gases x and y are elements
Explanation:
Since it is impossible to further break down the gases produced during this electrolytic process, we can conclude that the gases x and y are elements.
An element is a distinct substance that cannot be split up into simpler substances. Such substances are made up of only one kind of atom.
It is impossible through chemical reactions split an element into simpler units.

Answer:
find heat released by the burn:
(2 g) (19.4 kJ/g) = 38.8 kJ released
find heat gained by the water:
dH = m C dT
dH = (2250 g) (4.184 J/g-C) (+ 3.17 C)
dH = 29,842 Joules
aka
dH water = + 29.8 kJ
find the missing heat given to the calorimeter
(38.8 kJ released) - (29.8 kJ given to water) = 9.0 kJ given to calorimeter
What is the heat capacity of the empty bomb calorimeter
(9.0 kJ given to calorimeter) / (3.17 C rise in temp) = 2.84 kJ / C
