Answer:Flowing water creates energy that can be captured and turned into electricity. ... The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.

Answer:
Mass = 8.46 g
Explanation:
Given data Mass of water produced = ? Mass of glucose = 20 g Mass of oxygen = 15 g
Solution:
Chemical equation:
C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂
Number of moles of glucose:
Number of moles = mass/molar mass
Number of moles = 20 g/ 180.16 g/mol
Number of moles = 0.11 mol
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 15 g/ 32 g/mol
Number of moles = 0.47 mol
now we will compare the moles of water with oxygen and glucose.
C₆H₁₂O₆ : H₂O
1 : 6
0.11 : 6/1×0.11 = 0.66
O₂ : H₂O
6 : 6
0.47 : 0.47
Less number of moles of water are produced by oxygen thus it will limit the yield of water and act as limiting reactant.
Mass of water produced:
Mass = number of moles × molar mass
Mass = 0.47 mol ×18 g/mol
Mass = 8.46 g

Answer:
Si.
Explicación:
Sí, podemos predecir si una solución acuosa será un buen conductor de corriente eléctrica si conocemos el soluto que se disuelve en ese líquido y su concentración o cantidad. Hay algunas sustancias que se ionizan cuando se agregan en un líquido como el agua. Debido a esta ionización, será un buen conductor de electricidad. Por ejemplo, la adición de una gran cantidad de cloruro de sodio en agua ioniza y hace que el agua sea un buen medio conductor de electricidad.

Answer:
The correct answer is tetrahedral
Explanation:
Molecular geometry can be described as the three dimensional structure of atoms in a molecule. It is usually preferable to draw out the lewis dot structure of a compound before using that to determine the molecular geometry of the compound. The lewis dot structure and the tetrahedral structure of phosphoryl iodide (POI₃) are in the attachment below.
As it can be seen in the attachment, the molecular geometry of phosphoryl iodide is tetrahedral.
