What is the limiting reactant when 2.5 moles of Na reacts with 1.5 moles of Br2? 2Na(s) + Br2(g) arrow 2NaBr(s) For the reaction: 4NH_3 + 5O_2 ---> 4NO + 6H_2O; 15.0 g of NH_3 and 27.5 g of O_2 were reacted. a. Which is the limiting reactant? b. How many ...
If 691.1 g (NH4)2SO4 is reacted with excess NaNO3 and produces 732.3 g NH4NO3, what is the percent yield?Percent Yield:The theoretical yield of products that can be formed for a given chemical synthesis is not often reached. The amount formed in the react...
The past tense and -ed participle of bring is brought. My secretary brought my mail to the house. I've brought you a present. If you ask someone to bring you something, you are asking them to carry or move it to the place where you are. Can you bring me some water? 2. 'take'...
Temperature is another major driver in reaction kinetics, since increasing temperature increases the number of molecular collisions. In addition, the amount of energy needed to start a reaction is the activation energy. This energy is required to form the transition state, which occurs when reactant...
First, it is highly resistant to rust; iron, a major component of steel, reacts very easily with oxygen and moisture and will eventually disintegrate. The layer of zinc on the surface prevents those elements from reaching the steel so quickly. It also develops a patina — a layer of zinc...
That’s where a soldering iron, flux, and a little know-how come in handy. The solder and know-how make sense, but why do you need flux to solder? Read on to learn what it is, why you need it, and if you can use any alternatives for your project. Table of Contents [hide] ...
What is produced when a base reacts with water? What happens when iron (Fe) reacts with copper sulfate (CuSo4)? What will happen, if any, precipitate forms when aqueous solutions of silver nitrate (AgNO_3) and potassium carbonate are mixed? How to prepare 15 w% NaOH? What does the re...
Steel alloy in its simplest form is a basic mixture of Iron and Carbon and by varying the carbon content, the rate of cooling and the addition of impurities like Chromium for high corrosion resistance, we are able to derive alloys of different mechanical properties such as stainless steel and...
Triethanolamine,or TEA is a viscous, colourless/pale yellow liquid with a weak ammoniacal odour. Triethanolamine is incompatible with copper, copper alloys, galvanised iron, acids, and oxidisers. TEA is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approx...
Iron is a pure metallic element, while steel is an alloy made primarily of iron combined with carbon and sometimes other elements.
