Answer:
True
Explanation:because of the motion
Answer:
See the answer below.
Explanation:
Fire has three major components:
- Heat
- Smoke
- Gases ( in form of CO, CO2 etc)
If the victim had died as a result of the fire, he/he would have inhaled smoke and hot gases from the fire. These components would have resulted in traces of burns and soot deposition in the trachea and lungs as well as traces of CO in the blood of the victim.
If the analysis of the victim's corpse does not reflect some of the results above, it can be effectively concluded that the victim has been dead before the fire.
<em>The single most important indicator of death by the fire would be the presence of CO in the blood of the victim's corpse. All others might be to a less significant degrees.</em>
Explanation:
A 57.9 g sample of glass is cooled by 2.70'C how much heat does it release
1560
Answer:
3.39 g.mL⁻¹ or 3.39 g.cm⁻³
Solution:
Data Given:
Mass of Pellet = 12.4 g
Volume of Pellet = 13.65 mL - 10.00 mL = 3.65 mL
Density = ?
Formula Used,
Density = Mass ÷ Volume
Putting values,
Density = 12.4 g ÷ 3.65 mL
Density = 3.39 g.mL⁻¹ or 3.39 g.cm⁻³
Answer: The structure of
1-Butyne is shown below and it contains;
Nine Sigma Bonds Two Pi Bonds
Explanation:
In given structure the sigma bonds are highlighted with blue colour and pi bonds are highlighted by Black colour and indicated by red arrows.
Remember the very first covalent bond between two atoms is always the sigma bond. After formation of sigma bond if further p orbitals with unpaired electrons are available they will form pi bond, or two pi bonds as in given scenario.
