Halogens are a collection of elements that are found in group 17 on the periodic table. Groups are columns on the periodic table and the halogens can be found in the second right most column.Answer and Explanation: Halogens are found in nature only as compounds because they are highly ...
Why do calcium carbonate and marble have the same chemical compound? How do you make ammonium bicarbonate? Why is the electronegativity of an element important? Why are halogens found in nature only in compounds? a) How many molecules are there in 17.031 \text{ g} of ammonia, \text{NH}_...
The alkali metals react with most non-metals to form hydrides, oxides, sulphides, carbides, phosphides and other compounds. The binary compounds of all alkali metals are ionic withM+cations. The alkali metals easily ionize and readily reduce hydrogen ions. They react with ammonia to evolve hydr...
A class of plant hormones (especially INDOLE-3-ACETIC ACID (IAA) and similar compounds) that control cell division, cell expansion and differentiation. Cambium A population of stem cells that sustain the production of vascular tissues in higher plants. They allow the stem and the root to increas...
The rape plant (in the mustard family) contains cyanide-containing compounds and wild animals and even insects avoid it in nature. The refining process of deodorizing and bleaching to become canola oil involves exposing rapeseed oil to high heat, which greatly reduces the omega 3 content (perhaps...
The scientists behind the new theory – outlined on January 13 in leading international journalNature Reviews Neuroscience –suggest that changes in our ability to access specific memories are based on environmental feedback and predictability. Rather than being a bug, forgetting may be a functional...
<p>To understand why alkanes do not dissolve in water but do dissolve in benzene, we can break down the explanation into a few key steps:</p><p><strong>Step 1: Understand the Nature of Alkanes</strong> Alkanes are hydrocarbons, which means they are compo
Examples of compounds with covalent bonds are water, sugar and carbon dioxide.Ionic BondsIonic bonding is the complete transfer of valence electron(s) between a metal and non-metal. This results in two oppositely charged ions which attract each other. In ionic bonds, the metal loses electrons ...
Proteins carry out specific functions within the cell such as catalyzing chemical reactions, receptors and offering structure in the form of collagen or elastin for example. 570 Words 3 Pages Decent Essays Read More Biology: DNA And Macromolecules Carbohydrates are compounds made up of carbon, ...
Why do metallic compounds conduct electricity as a solid? Why do metals only form ionic compounds while metalloids and nonmetals form ionic and covalent compounds? Why do ionic compounds conduct electricity in an aqueous solution or when molten, but do not conduct electricity when in the solid-st...
