Answer: D
Explanation:
Balanced force is when 2 equal forces are acting on each other, summing force isn’t a thing, unbalanced force is when 2 unequal forces are acting on each other, and net force is the total amount of forces acting on an object. Hope this helps!
CH4+ 2O2---> CO2+ 2H2O I believe would be correct.
Explanation:
1.
Sodium, or Na, is 57.47% of the composition,
Hydrogen, or H, is 2.520% of the composition,
and Oxygen, or O, is 40.001% of the composition.
This is because mass% = mass/total mass x 100%.
2. For every 1 mole of C6H12O6, you need 6 moles of water. Multiply the 5.2 moles you are trying to make by the 6 moles of water you need, and you will need 31.2 moles.
3. x = 7.2 x 4 / 2 = 14.4 mol
Answer:
A. Up
B. Out
C. Out
D. To equilibrum
Explanation:
a. The reaction in an exothermic reaction so this means heat is given off. If the cylinder is thin enough heat will transfer to the water bath
b. Since the products will create heat which will increase pressure, the piston in an attempt to maintaining a constant pressure will move up to accommodate building pressure.
c. Heat will flow out of the gaseous mixture as this reaction creates heat as a product as well
d. Heat will flow out in the capacity to create an equilibrium with the water bath that it is in.
