Hydrogen gas is placed inside container B. Both containers are the same volume and both gases are at the same temperature and pressure. What can be said about the number of particles inside of each container? 11 The container that holds the gas of higher density will have more particles in it. Container B will have more particles in it because hydrogen has a lower molar mass than carbon dioxide. Nothing can be concluded about the number of particles based on the information given. Both containers will have the same number of particles in them. Bonus: A sample of gas contains NO, NO,, and N,O. The pressure of the gas mixture is 4.68 atm. The pressure of NO is1.2.

Read the description about an experiment conducted and identify the following parts of scientific method. (30 pts) A farmer wanted to investigate whether a bamboo palm plant grow better inside or outside. His initial thought was that there will be no difference between the growth in indoor or outdoor. He decided to plant ten plants in identical pots using same type and same amount of soil. Then he placed five of them in outdoor location and the other five in an indoor location. The outdoor plants were receiving same amount of sunlight and both indoor and outdoor plants were given same amount of water. Each day for three weeks the plant growth was observed and measured by recording the size of each plant. It was observed that the indoor plants had grown more in size than the outdoor plants.
