Ques: Q: In what state do ionic compounds best conduct electricity? Read this paragraph and choose the correct option from the provided answers: Solid ionic compounds are poor conductors of electricity. The strong bonds between ions lock them into place in the crystal. However, in the liquid state, ionic compounds are good conductors of electricity. Most ionic compounds dissolve easily in water. When they dissolve, they separate into individual ions. The ions can move freely, so they are good conductors of electricity. Dissolved ionic compounds are called electrolytes. Choices: - gas - solid - plasma - liquid A:
Ans: liquid

Q: The fuel that burns in a combustion reaction in many fossil fuels such as natural gas that consists of carbon hydrogen is known as what? Read this paragraph and choose the correct option from the provided answers: The fuel that burns in a combustion reaction is often a substance called a hydrocarbon. A hydrocarbon is a compound that contains only carbon (C) and hydrogen (H). Fossil fuels, such as natural gas, consist of hydrocarbons. Natural gas is a fuel that is commonly used in home furnaces and gas stoves (see Figure below ). The main component of natural gas is the hydrocarbon called methane (CH 4 ).
