Answer:
Mass = 6.79 g
Explanation:
Molarity = 0.155
Volume = 0.75L
Mass = ?
The relationship between these quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Volume * Molarity
Number of moles = 0.75 * 0.155 = 0.11625 moles
Number of moles = Mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 58.44277 g/mol * 0.11625 mol
Mass = 6.79 g
Answer:
0.464 L
Explanation:
Molarity (M) = number moles (n) ÷ volume (V)
According to the information given in this question:
number of moles (n) = 4.36 moles
Molarity = 9.4M
Volume = ?
Using M = n/V
9.4 = 4.36/V
9.4V = 4.36
V = 4.36/9.4
V = 0.464 L
Hence, 0.464L of water are needed the volume of water.
Answer:
Photosynthesis
Explanation:
Carbon cycle involves the exchange of components between the hydrosphere, biosphere and atmosphere. During carbon cycle, materials such as gases, minerals which are necessary for life are interchange. For example, animals pass out faeces on the soil which is rich in urea. Urea decomposes to provide nitrogen into the soil through bioactive bacterials. The nitrogen is used up by plants to grow. During photosynthesis, plants uses carbon dioxide and water to produce glucose and release oxygen for animals to use. It's like a purification system where one waste product from one organism is used by the other to survive.
Equation of photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
