Answer:
The percentage yield of water is 66.67%.
Explanation:
Mass of oxygen gas = 100 g
Moles of oxygen gas = 
According to reaction, 1 mole of oxygen gives 2 moles of water, then 3.125 moles of oxygen will give:
Mass of 6.25 moles of water :
6.25 mol × 18 g/mol = 112.5 g
Theoretical yield of water = 112.5 g
Experimental yield of water = 75 g
Percentage yield :
The percentage yield of water is 66.67%.
conduction : a spoon resting in a cup of tea gets hot
convection: water warming on the stove
Radiation: The sun warming the earth
Answer:
Alkenes, Markovnikov's, Alkenes, Alkyl halides, and less.
Explanation:
Alkenes must undergo addition because they have easily broken π bonds.
Markovnikov's rule states in the addition of HX to an unsymmetrical alkene, the H atom bonds to the less substituted carbon atom.
Alkenes are unsaturated hydrocarbons because they have fewer than the maximum number of hydrogen atoms per carbon.
Alkyl halides have good leaving groups and therefore readily undergo substitution and elimination reactions.
In hydroboration, the boron atom bonds to the less substituted carbon.
The answer for this one is a

Explanation:
- The products formed are chromic chloride and cobalt.
Chromium + Cobaltous Chloride = Chromic Chloride + Cobalt
- Type of reaction is Single Displacement (Substitution) which is there is a displacement of one atom.
Reactants used in the reaction are -
- Chromium
- Cobaltous Chloride
Products formed in the reaction are -
- Chromic Chloride
- Cobalt
Hence, the chemical reaction is as follows -
→
For balancing the above chemical equation we need to add a coefficient of 2 in front of chromium and of 3 in front of cobalt(II)chloride on right-hand-side while of 2 in front of chromium chloride and of 3 in front of carbon monoxide on left-hand-side of the equation.
Hence, the balanced equation is -
→
