Option Pros Cons No dangerous by-products Heat time of 3 minutes Bulky #1 Very environmentally friendly- products will react with CO2 (removing it from the atmosphere, lowering greenhouse gases) and make chalk and water Not able to heat well in cold weather #2 Heat time of 5 minutes Readily available Reactant can be unstable when heated #3 Produces hydrogen gas (flammable) in a heated, pressurized container. Your scientists have determined that this is an explosion risk. Uses much less material for same amount of #4 heat 90 second heat time 5. Santa cares about being green and saving the environment, and on the Polar Express, what Santa wants, he gets. Keeping in mind all of the pros and cons, the cost of each option, and the option you excluded in Question 1, which option do you think your company should go with? Explain your reasoning.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Given options:
1. The cost of CaCI2 = $69,000.
