Why nh4cl is used in dry cell? The ammonium ions move towards the carbon electrode where they reduce manganese dioxide to Mn2O3 with the formation of ammonia and water. The ammonia thus formed is not liberated as gas but it combines with zinc ions and chloride ions to form a complex salt. What is an […]
What changes wave period?
What changes wave period? The wave period is also dependent on the wavelength and the velocity. The higher the velocity, the lower the wave period, and the higher the wavelength, the higher the wave period. Do swell waves break? When swell finally reaches shallow water- whether that be a continental shelf, a reef system, or […]
Which one of the following has the largest lattice energy nabr?
Which one of the following has the largest lattice energy nabr? NaF Which of the following compounds will have the largest lattice energy? AlBr3 have the largest lattice energy. Because of the greater charge on Al3+ ions and Br− as lattice energy is directly proportional to the charges of the combing atoms. Why does mgcl2 […]
In which situation is a person doing work on an object?
In which situation is a person doing work on an object? Answer : When a person applies force and covers distance then the person is doing work on an object. What type of force causes a change in motion? Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the […]
How fast should a 15 year old throw?
Can adenine pair with itself?
Can adenine pair with itself? Adenine always pairs with thymine, and cytosine always pairs with guanine. The pairing nature of DNA is useful because it allows for easier replication. If you know one side of a DNA molecule, you can always recreate the other side. Each base has only one other base it can pair […]
Why is distracted driving so bad?
Why is distracted driving so bad? Distracted driving causes a large amount of physical damage and claims many lives each year. There is more to distracted driving than texting, such as grooming, eating, and more. These visual, manual, and cognitive tasks can wait for when you are not at the wheel. Why is texting a […]
What happens when a charge is placed inside a conducting shell?
What happens when a charge is placed inside a conducting shell? So if you place a point charge inside a conducting shell the inner side of the conducting shell will have same amount but opposite charge distributed so that a Gaussian surface in side the conducting material have zero enclosed charge, which is required to […]
Where do electrons go when they are lost?
Where do electrons go when they are lost? In other words, the electron does not ‘go’ anywhere – they are shared between the atoms; the loss of one is the gain of the other. How many electrons are gained or lost in oxygen? two electrons How many electrons will iodine? 53 electrons How many protons […]
