False, because generally forensics collect the evidence to make sure the evidence doesn’t get damaged or tainted.... hope this helps
Energy transfer is an extension of Newton’s Laws. Energy cannot be created nor destroyed; it can only be transferred. The moving body has energy, called kinetic energy, and this energy will be transferred into something else as the body slows. Likewise, the car crashing into you will transfer its kinetic energy to you. The other type of energy is potential energy, or stored energy. Think of a spring. When you pull it, you are storing energy. When you let it go, this potential energy is transferred into kinetic energy as motion. Car manufacturers engineer a purposeful flaw into the structure, the Crumble Zone. This Crumble Zone is a structurally assigned place for kinetic energy to be transferred into potential energy in the case of an accident. When two cars collide, the kinetic energy is used up to fold the metal of the auto, keeping the destructive energy out of the passengers. The same science is behind the recommendation that motorcyclists wear helmets and body armor. Auto crumble zones, as well as air bags, helmet foam and Kevlar, are all methods for converting harmful kinetic energy into safe potential energy.
Less than the reactants I think
Answer:
5.8 g of carbon dioxide are produced
Explanation:
The Law of Conservation of Mass states that the mass of the reactants must equal the mass of the products in all chemical reactions.
This is the chemical reaction (combustion)
CH₄ + 2O₂ → CO₂ + 2H₂O
12.2 g 14 g x 20g
Mass in reactants = 12.2 g + 14 g = 26.2 g
Mass in products = x + 20 g
26.2 g = x + 20g
26.2 g - 20g = x
5.8 g = x
Answer:
Here are some guidelines for disposal of the following categories.
1. Glass
• Broken glasses should be clean, without odors or chemical debris.
• It should be collected in a cardboard box which bottom is taped.
• The box should be closed
• Label box "CLEAN BROKEN GLASS FOR RECYCLING"
• Contact the Custodial Services for removal of the box.
2. Chemical waste after reaction & Unused chemical.
• Disposal of such chemicals must be disposed of corresponding to the instructions obtained from the manufacturer or better still through licensed chemical removal company.
• A plan for disposal and procedures for chemicals disposal should be known before they are purchased.
• Based on the classification some waste should be held in the laboratory while others shouldn't be disposed during day light the characteristics of the solution.
• Overstock should be given to neighboring schools.
