How do tidal power plants generate electricity? A barrage allows water to flow during high and low tide, this turn's the plant's turbines. A barrage holds back water during high tide. The force of the water against the barrage turns the plant's turbines. A barrage store water during high and low tide. When the water is released, it turns the plant's turbines. A barrage stops water from flowing out at low tide, creating a force that turns the plant's turbines.

What is the most stable monatomic ion formed from nitrogen

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
