Write a balanced chemical equation based on the following description: solid CH1,0 is burned with oxygen gas to produce gaseous carbon dioxide and water vapor

Write a balanced chemical equation based on the following description: solid cesium reacts with solid cesium nitrite to form cesium oxide and nitrogen gas.

Balance the following chemical equation (if necessary): Si,H_(s) + O,(g) → SiO,(g) + H̟O(g)

Write balanced chemical equations for the following chemical reactions.       a Lime (calcium oxide) when reacts with water and produces slaked lime (calcium hydroxide).

A solution is formed by dissolving 2.000 kg of sugar (sucrose, density = 1587 kg·m−3) in 1.000 kg of water (density = 1000 kg·m−3). Assume that the volume of the solution formed is the sum of the sugar volume and the water volume. a)  What is the final volume of the solution? b)  What is the density of the solution?

Combustion of hydrocarbons such as hexane (C6H₁4) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid hexane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.220 kg of hexane are burned in air at a pressure of exactly 1 atm and a temperature of 17.0 °C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits. ローロ X 0 x10
