Answer:
Mass of hydrogen needed = 10 g
29.22 gram of sodium are required
Explanation:
1 )Given data:
Mass of oxygen = 80.0 g
Mass of hydrogen needed = ?
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 80 g/ 32 g/mol
Number of moles = 2.5 mol
now we will compare the moles of oxygen and hydrogen.
O₂ : H₂
1 : 2
2.5 : 2× 2.5 = 5 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 5 mol × 2 g/mol
Mass = 10 g
2 : Given data:
initial mass ration of chlorine and sodium react with each other = 1.54 g : 1.0 g
Mass of sodium required for 45 g of chlorine = ?
Solution:
Cl₂ : Na
1.54 : 1.0
45 : 1.0/1.54× 45 = 29.22 g
Thus, 29.22 gram of sodium are required.
Answer: Concentration of at equilibrium = 0.08 M
Concentration of at equilibrium =0.08 M
Concentration of = 0.64M
Explanation:
Moles of = 4.00 mole
Volume of solution = 5.00 L
Initial concentration of =
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the given chemical reaction:
Initial conc. 0.8 M 0 M 0 M
At eqm. conc. (0.8-2x) M (x) M (x) M
The expression for is written as:
Concentration of at equilibrium = x M = 0.08 M
Concentration of at equilibrium = x M = 0.08 M
Concentration of = (0.8-2x) =
Answer:
the answer is 18 atoms [your welcome]
That would be oxidation.
Oxidation is loss of electrons
Reduction is gain of electrons
Answer:
Explanation:
Explanation:
If Earth’s temperatures increase, it would likely have these effects:
The East Coast of the United States will face an increased risk of hurricanes as warmer waters increase evaporation.
The polar region will experience melting ice caps, which will cause sea levels to rise.
Warmer water in the Great Lakes will cause heavier lake-effect snows.
In the Pacific Ocean, heating of the water will cause a change in convection currents.
Hot, dry conditions will increase the risk of wildfires in the forests of California.
In the Himalayas, animal and plant life will migrate to higher ground to live.
The coastal regions of Europe will be at greater risk of flooding because of rising sea levels.
