Chemical reactions occur when a substance either shares or donates electrons with another substance. They involve the breaking of old chemical bonds and the creation of new ones.Answer and Explanation: When chlorine reacts with hydrogen the product formed is hydrogen chloride(HCl). This compound is...
For example, chemistry is at work when water freezes into ice or metal rusts. Chemists explore these changes and try to understand why they happen. They study the properties of materials and how they react with one another. This knowledge helps create new products, medicines, and technologies ...
Why does HCl behave as an electrophile? What is the arrhenius definition of an acid? What is an example of a chemical property? What are the physical properties of carbonate minerals? What is the definition of a Lewis acid? What are some chemical properties of einsteinium?
a lot of energy is required to break the bonds between the atoms in a nitrogen molecule. This energy can come from lightning, which causes some nitrogen to combine with oxygen, forming nitrogen oxides. These can dissolve in rainwater to form very dilute nitric acid, which reacts...
“colleagues”, since all vitamins are essential. A whole series of essential minerals are also necessary, so it is not too difficult to understand that all these ingredients must be obtained by nutrition. The body cannot make vitamins or essential minerals. There is also some evidence that ...
Baking Soda test (non-scientific):After you have gotten up in the morning, and before eating or drinking, mix about 1/4 tsp baking soda in a cup of water and drink it down. Watch to see if you have burped in the next 2 – 3 minutes (stomach acid and baking soda react to form ...
Molarity is the most common way of expressing concentration when working with solutions and chemical reactions. The reason is that reactants (elements or compounds) combine in whole-number ratios when their amounts are expressed in units called "moles." For example, 2 moles of hydrogen gas ...
The most common white minerals in the calcite group react differently to cold and hot acid, as follows: Calcite (CaCO3): bubbles strongly in cold acid Magnesite (MgCO3): bubbles only in hot acid Siderite (FeCO3): bubbles only in hot acid ...
I have a great wardrobe I can't go anywhere near. It's all in tubs. If I put it in the closet I react to it from across the room! I'm living with minimal clothing to wear and it's become very difficult. I've tried those detergent strippers, washing them in tons of vinegar and...
it hydrates the concrete’s calcium oxide. The resulting calcium hydroxide reacts with carbon dioxide in the air, starting a process called autogenous healing, where microscopic calcium carbonate crystals form and gradually fill the gap. Unfortunately, these crystals can only do so much, healing cra...
