2.0 g of H2 gas reacts with 32 g of O2 gas to form water. Assuming the reaction goes to completion, how many grams of water will be produced?
Answers
Answer 1
Answer:
In order to solve this problem, the balanced chemical equation of the reaction must be used. This gives the equation:
2H2 + O2 --> 2H2O
Next, the moles of the reactants must be used in order to apply their stoichiometric relationships. Note that 1 mole of oxygen needs 2 moles of hydrogen for the reaction proceed. Since there is only 1 mole of H2, only 0.5 moles of oxygen are consumed.
True because they need charge in order to make a covalent bond I just learned that

What is the mass of 0.7891 mol of (fe2o3)?
Answers
Molar mass F₂O₃ = 159.69 g/mol
1 mole ------------------ 159.69 g 0.7891 moles ---------- ? g
mass = 0.7891 x 159.69 / 1
= 126.01 g
hope this helps!
How are the atoms in an object affected when the temperature of the object increase?
Answers
As the temperature is increased, the atoms displace their neighboring atoms and this chain goes continuously due to which energy is transferred from one atom to their neighbor atom like wise vibration and energy increases.
