<span>Most items of evidence will be collected in paper containers such as packets, envelopes, and bags. Liquid items can be transported in non-breakable, leakproof containers. Arson evidence is usually collected in air-tight, clean metal cans. Only large quantities of dry powder should be collected and stored in plastic bags. Moist or wet evidence (blood, plants, etc.) from a crime scene can be collected in plastic containers at the scene and transported back to an evidence receiving area if the storage time in plastic is two hours or less and this is done to prevent contamination of other evidence. Once in a secure location, wet evidence, whether packaged in plastic or paper, must be removed and allowed to completely air dry. That evidence can then be repackaged in a new, dry paper container. UNDER NO CIRCUMSTANCES SHOULD EVIDENCE CONTAINING MOISTURE BE PACKAGED IN PLASTIC OR PAPER CONTAINERS FOR MORE THAN TWO HOURS. Moisture allows the growth of microorganisms which can destroy or alter evidence.

Keep the gun in some of the water, the prints could still be on the gun if any crime was done. drying it out will only add prints to it.

True or false? The molar mass of a gas determines the amount of kinetic energy of the gas.
HACTEHA [7]
The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>

Why do scientists establish boundaries for natural systems?
andrezito [222]

<>"The researchers stress that their approach does not offer a complete roadmap for sustainable development, but does provide an important element by identifying critical planetary boundaries. "Human pressure on the Earth system has reached a scale where abrupt global environmental change can no longer be excluded."<>

Why is it important to heat analytical reagents and store them in a dessicated atmosphere before use?
schepotkina [342]

Explanation:

In normal atmosphere, analytical reagents may absorb water molecules that may affect the results of chemical reactions. So, in order to get accurate results from these analytical regents, they must be stored in a dessicated atmosphere or heated before being used so that the water molecules must dry away.

The original gas volume in a balloon is 50.mL when the pressure is 1.00 atm. Predict the new gas volume when the pressure is 3 t
damaskus [11]
According to Boyle's law, Volume is indirectly proportional to the pressure.

So, P1V1 = P2V2

Substitute the known values, 
1 * 50 = 3 * V2

V2 = 50/3 = 16.67 mL

In short, Your Answer would be: 16.67 mL

Hope this helps!

A chemist determined by measurements that 0.0500 moles of nickel participated in a chemical reaction. Calculate the mass of nick
Rashid [163]

Answer:

2.94 grams Nickle

Explanation:

All they are asking is to convert moles to grams

To do this, find the atomic mass of nickel using the periodic table: 58.693 g

0.05 mol * 58.693 g/1 mol = 2.93465 grams
