Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body. Transfer stains result from objects coming into contact with existing bloodstains and leaving wipes, swipes or pattern transfers behind such as a bloody shoe print or a smear from a body being dragged. Impact stains result from blood projecting through the air and are usually seen as spatter, but may also include gushes, splashes and arterial spurts. Blood spatter is categorized as impact spatter (created when a force is applied to a liquid blood source) or projection spatter (caused by arterial spurting, expirated spray or spatter cast off an object). The characteristics of blood spatter depend on the speed at which the blood leaves the body and the type of force applied to the blood source.
I got this from article I hope it helps!
Drink plenty of water yep that should help
B.) air pollution
because travelers get malaria so i think it would be air pollution.
Answer:
If you have the Coronavirus, you should start self-isolating. Which means, staying away from everybody. Don't touch things, stay in your room stuff like that. You should call your doctor and tell him or her about your symptoms. Just make sure you stay away from everybody, until you no longer have symptoms.
Hope this helps!!
Answer:
0.2558 g
Explanation:
1.- In titration, since you have the concentration and the volume of the titrant and the aliquot that you take, you can use the formula C1 V1 = C2 V2.
2.- To obtain C2 = C1 V1 /V2
Substitution C2 = (0.0149 M ) (9.75 ml) /25 ml = 0.0058 11 M
3.- This concentration is the number of moles that you would have in 1 L but you dissolve your tablet in 250 ml, so a rule of three.
4.- 0.005811 moles - 1 L
x - 0.250 L
X= 0.250 L x 0.005811 moles / 1L = 0.00145275 moles
5.- using your molecular weight, you can obtain the grams with another rule of three.
0.00145275 moles - x
1 mole - 176.12 g
x= 176.12 g x 0.00145275 moles / 1 mole = 0.2558 g
