How much copper (solid) can be made by the reaction of 0.47 moles of sodium with 26g of copper (II) Nitrates?
How much copper (Solid) can be made by the reaction of 0.47 moles of sodium with 26g of copper (II) nitrate? 2Na (s) + Cu (NO3) 2 -> 2NaNO3 Cu + (s)
This is a very silly question, since it is composed by a person who does not know their chemistry! If you mix copper nitrate and solid sodium crystals, nothing will happen to unless they leave at some point. After copper nitrate, to be deliquescent absorb water and begin to dissolve. Some of the sodium reacts with water. If you try to heat solids together, copper nitrate dissolved in the water of crystallization before decomposition and again partly sodium reacts with water. If the copper nitrate is in solution, the sodium reacts to a high percentage of water instead of shifting to copper metal the copper nitrate solution. 2Na (s) + 2H2O (l) —> 2NaOH (aq) + H2 (g) below, Cu2 + (aq) + 2OH-(aq) —> Cu (OH) 2 (s) Next, the copper nitrate is precipitated as copper (II ) hydroxide This type of displacement reaction works well with other metals such as iron and iron filings, and you can do a lab in it, but this is stupid ask a question based on misleading chemistry! At most only some of the displace sodium copper. You can make a calculation assuming that the works .. but what is where the chemistry is correct? What do you teach?

When it comes to decorating your home, sometimes it’s little things that get noticed. One interesting and well-organized stress can give your home a completely new look. If you want to update the look without breaking the bank, then why not try to add to your dome roof? This small accessory can be of great importance in terms of style and functionality, and provides many opportunities for creativity. Read on to learn more about them.
Domes are small structures emphasizing the upper roof or dome. They are designed to look like miniature houses and are often used on bowers and pavilions. But although they are mainly decorative, they canbeso very functional: they air circulation around the house, and in the daytime, to provide an inexpensive source of light.
Word of the dome from Latin and means “small cupo”, which means a small dome. Most modern domes are made of wood or vinyl cupolas and shingles or copper roof. They may also have small blinds for light and ventilation. Because of their combination of style and functionality, domes have long been used in homes and public buildings as well.
The domes were first used in Islamic buildings (in particular, mosques) around the beginning of the 8th century. They reached the tower and were large enough to be used as prayer rooms. For the spread of Islam in Europe, the dome has been integrated in many churches, the most striking example is the top of the dome church of Saint-Petersburg, Russia. After the domes reached English shores, it was not long before the Americans also raised.
The Indians were the first to use domes for homes. Seeing their practical benefits, they made a smaller version, from three to four feet in diameter, which can be used for domestic dwellings. In the end, the dome has become a miniature and a stylized decorative become the main structure it is today.
Wood remains the most preferred material because of its natural, earthy look and a fair resistance to weather. He also does not retain heat, so hot air passes through the windows or blinds. The most commonly used woods of pine, mahogany, poplar, cedar. Wood cupolas are usually topped with a metal roof.
Metal domes give you much more opportunity for style and usually last longer than wood. Among the styles that you can choose from are the Victorian, Squire, Lodge, and modern. Copper finial is far from metal choice for the majority, because it is naturally attractive and can be left treated or untreated. Lead-coated copper retains its color, but the untreated copper will patina, Dark Green, which many people find attractive.
Vinyl cupolas highly weather, but do not offer much in terms of aesthetics. There are not many options for color, and in any case, the colors tend to fade with constant heat and rain effects. However, they require virtually no maintenance and will last for years if properly. Many of the new domes are made of fiberglass, which are the most solid yet. They come in almost any size and shape, and can withstand strong winds and bad weather. The only drawback is that they are more expensive, but if you’re after beauty and quality, it is certainly worth a try.
