Answer;
D, Xe (g)
Solution and explanation;
If 2g has a volume of 340ml.
Density is 1000/340*2 = 5.88g/litre.
-This rules out the two solids, choices 2) &3)
If 1 litre has mass 5.88g,
then 22.4 liters (volume at STP) has mass 5.88*22.4 = 131.8g/mol
molar mass Br2 = 80*2 = 160g/mol NO
molar mass Xe = 131.3g/mol = YES.
Answer is Xe
Answer:
Liters
Explanation:
Just like meters, liters is used to calculate large volumes of liquid, not solids. :) I hope this helped!
Answer:
Forest Fire
Explanation:
Forest fire is an ecological factor over which biological processes like seed dispersal and their germination is dependent upon. Some plants germinate under high temperature underground regions of the soil which is covered by the hot soil affected by the burning by the forest fire. Some of the coniferous trees like longpole pines have hard cone which exhibit the seeds. These cones exhibit the serotonin resins which are melted by the forests fire hence fire helps in dispersal of the seeds. Other plants like Eucalyptus and Banksia are also dependent upon fire for seed dispersal.
In the polymerization of dna, a phosphodiester bond is formed between a phosphate group of the nucleotide being added and <span>the OH </span>of the last nucleotide in the polymer.
