Answer:
one mole of oxygen will produce 
moles of water
Explanation:
The balanced chemical reaction is as follows -
2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O
As we can see in this reaction
5 mole of oxygen (on the reactant side) will produce 2 mole of water (on the product side)
Hence, one mole of oxygen will produce 
moles of water
Answer:
Explanation:
Equilibrium is the state in which the resultant of all forces acting on an object is zero. This implies that the object do not rotate or move, but well balanced at a point. Equilibrium can either be dynamic or static.
When two unbalanced forces act on an object, the object move in the direction of the greater force. This effect nullifies equilibrium of the object.
i. Tim versus Elena and Anne - Unbalanced balanced
⇒ 70 - (100 + 30) = -60N
ii. Elena versus Tim and Anne - Balanced
⇒ 100 - (70 + 30) = 0N
iii. Anne versus Tim and Elena - Unbalanced
⇒ 30 - (70 + 100) = -140N
It's (grams-of-Cl/total-grams)(100), so (35.45g/58.44g)(100) = 60.66% Cl. Hope this helps!
