Answer:
warm water is denser than cold water
Explanation:
Answer:
Me India is located in Asia and its capital name is New Delhi.
Answer:
Explanation:
Given data:
Mass of water used = 4.05 g
Mass of each product produced = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
Number of moles of water:
Number of moles = mass/ molar mass
Number of moles = 4.05 g/ 18 g/mol
Number of moles = 0.225 mol
Now we will compare the moles of water with hydrogen and oxygen.
H₂O : H₂
2 : 2
0.225 : 0.225
H₂O : O₂
2 : 1
0.225 : 1/2×0.225 = 0.113 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.225 × 2 g/mol
Mass = 0.45 g
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.113 mol × 32 g/mol
Mass = 3.616 g
Answer:
high, low
Explanation:
In simple diffusion, molecules move from an area of high concentration to an area of low concentration.
