What is the correct formula for sulfur hexafluoride?
What is the correct formula for sulfur hexafluoride?
SF6
What is the molecular geometry of SBr6?
Octahedral Trigonal Bipyramidal Tetrahedral Bent Trigonal Pyramidal.
What does sulfur combine with?
It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements. Millions of tons of sulfur are produced each year, mostly for the manufacture of sulfuric acid, which is widely used in industry.
What is sulfur used for?
Elemental sulfur is used in black gunpowder, matches, and fireworks; in the vulcanization of rubber; as a fungicide, insecticide, and fumigant; in the manufacture of phosphate fertilizers; and in the treatment of certain skin diseases. The principal use of sulfur, however, is in the preparation of its compounds.
What elements does sulfur bond with?
Two hydrogen (H) atoms can bond with one sulfur (S) atom, making the formula H2S, also known as hydrogen sulfide. The same way that oxygen is happy when it has two extra electrons, sulfur likes to have two extras as well. See how the sulfur atom gets to share each of the electrons from the hydrogen atoms?
Why is sulfur so important?
Sulfur is essential to all living things. It is taken up as sulfate from the soil (or seawater) by plants and algae. It is used to make two of the essential amino acids needed to make proteins. It is also needed in some co-enzymes.

What happens when you mix sulfur and vinegar?
hydrogen sulphide, formula H2S. This compund forms by a chemical reaction between the vinegar (an acid) and small amounts of metal sulphides (= compounds of a metal and sulphur). It has the well-known rotten-egg odour. These metal sulphides may be present in the ashes or may be contaminations in iron ash trays.
What two chemicals should you never mix?
- Bleach and Ammonia = Toxic Chloramine Vapor. Bleach and ammonia are two common household cleaners that should never be mixed.
- Bleach and rubbing alcohol = Toxic chloroform.
- Bleach and vinegar = Toxic Chlorine Gas.
- Vinegar and Peroxide = Paracetic Acid.
- Peroxide and Henna Hair Dye = Hair Nightmare.
What are the most dangerous chemical reactions?
The top 10 most dangerous chemical reactions
- Making Hydrogen fluoride. Hydrogen fluoride is a colorless gas which has a rather acrid smell.
- Berthollet’s salt and red phosphorous.
- Pharaoh’s Serpent or the Kraken.
- Making phosphine.
- Cesium and water.
- Making nitrides.
- Making hydrochloric acid.
- Burning magnesium.
What are the 3 most important chemical reactions?
- Synthesis of ammonia.
- Combustion of hydrogen / Electrolysis of water.
- Combustion of methane (hydrocarbons)
- Photosynthesis.
- Synthesis of sulfuric acid.
- Equilibrium of carbonic acid and carbon dioxide gas.
- Biological formation of calcium carbonate.
- Rusting of iron.
What is the most important chemical on Earth?
Sulfuric acid is the world’s most important industrial chemical! In North America we produce about 50 million tons a year, mostly by burning sulfur to form sulfur dioxide which is then reacted with water. Why do we need all that sulfuric acid? Primarily to produce fertilizer.
What is the most important chemical reaction?
Photosynthesis
What are the 4 types of chemical reaction?
Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.
What are five general types of reactions?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
Is an explosion a chemical reaction?
Brilliant fireworks are exploding in the night sky. The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. Another words, the composition of the substance changes.
What causes a chemical reaction?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What are signs of chemical reaction?
There are five signs of a chemical change:
- Color Change.
- Production of an odor.
- Change of Temperature.
- Evolution of a gas (formation of bubbles)
- Precipitate (formation of a solid)
How do you classify a reaction?
Classifying Chemical Reactions
- Synthesis reactions. Two or more reactants combine to make 1 new product.
- Decomposition reactions. A single reactant breaks down to form 2 or more products.
- Single-replacement reactions. A single element replaces a similar element of an adjacent reactant compound.
- Double-replacement reactions.
- Combustion reactions.
What is chemical reaction explain with an example?
A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water. things burning or exploding.
What are the two types of chemical reactions?
Types of Chemical Reactions: Single- and Double-Displacement Reactions
- Recognize chemical reactions as single-replacement reactions and double-replacement reactions.
- Use the periodic table, an activity series, or solubility rules to predict whether single-replacement reactions or double-replacement reactions will occur.
What does chemical reaction mean?
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What happens during a chemical reaction?
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.
