A chemical reaction occurs when chemicals combine to form new substances with new properties. Burning is a rapid type of chemical reaction that produces large amounts of heat and light. An example of a fast chemical reaction is an explosion, such as the exploding of fireworks or a bomb. An example of a slow chemical reaction is rusting (or oxidisation). One of the chemicals produced during burning is carbon dioxide, which we now refer to as a 'greenhouse gas'.
A round of applause, please, for the number one dog breed in the U.S.: The labrador retriever. The American Kennel Club announced 2015's most popular dog breeds in the U.S. on Monday with the beloved lab topping the list for the 25th consecutive year, the longest reign for any breed. The lab is a family dog, a great exercise companion and comes in three lovely colors, Gina DiNardo, Vice President at AKC said at the top breeds unveiling.
Meanwhile, the popular French Bulldog continues its quest for the number one spot, breaking into the top 10 for the first time in nearly 100 years this year at number nine. The Dachshund was knocked out of the top 10 this year for the first time since 1985, landing at number 11. âThe Lab truly is Americaâs dog,â said AKC Vice President Gina DiNardo, âbut the lovable Bulldog breeds are clamoring to dominate. Watch out for an upset next year.â.
