Answer:
The limiting reactant is oxygen gas and the reaction would produce 3.932 x 10 ^ 7 moles of water
Explanation:
Step 1: Convert everything into moles
nH2(l) = 1.06 x 10^8 g / 2.016 g/mol = 5.26 x 10^7 mols
nO2(l) = 6.29 x 10^8 g / 32.00 g/ mol = 1.966 x 10^7 mols
Step 2: Find the limiting reagent
The limiting reagent would be oxygen gas from
the balanced equation because we have less moles of oxygen gas needed to fully combust with the hydrant gas
Step 3: Stoichiometry time
The mole ratio from oxygen gas to water is 1:2
This means that for every mole of oxygen gas two moles of water is produced
We need to multiply the moles of oxygen gas by two to find out how many moles of water has been produced
nH2O = nO2 x 2
nH2O = 1.966x10^7 x 2
nH2O = 3.932x10^7
Step 4: Therefore statement
Therefore the limiting reactant is oxygen gas and the reaction would produce 3.932 x 10 ^ 7 moles of water
Answer:
1. Sp^3; Sp.
2. Isomers.
3. Weaker.
4. Atomic; hybrid.
5. Pi.
6. Electronegativity.
7. Resonance structures.
8. Sigma.
Explanation:
1. A tetrahedral carbon is Sp^3 hybridized while a linear carbon is Sp hybridized. A tetrahedral carbon typically comprises of four bonds that are 109. 5° apart while a linear carbon atom comprises of two (2) bonds that are 180° apart.
2. Two different compounds that have the same molecular formula are known as isomer. For example Butane and Isobutane, Methoxyethane and Propanol have the same molecular formula (numbers of hydrogen and carbon atoms) but different structural formula.
3. Pi (π) bonds are generally weaker than sigma (σ) bonds. This is because the orbital paths of Pi bonds are parallel thereby causing an overlap.
4. Hybridization is the combination of two or more atomic orbitals to form the same number of hybrid orbitals, each having the same shape and energy.
5. A Pi bond is formed by side-by-side overlap of two p orbitals.
6. The electronegativity is a measure of an atom’s attraction for electrons in a bond and indicates how much a particular atom "wants" electrons.
7. Two Lewis structures that have the same atomic placement and σ structure but a different arrangement of π electrons are called resonance structures.
8. All single bonds are Sigma bonds.
Answer: I think you have to subtract the distances
Explanation:
Alkali metals impart characteristic colours to the flame due to low ionisation enthalpy, when an alkali metal or its salt is heated in a flame, the valence electrons are excited to higher energy level.
I think the answer is 47.1 . I'm not sure. Iv'e done it before but I haven't got my grade for the answer yet. Hope this right and hope it helps!
