How are cone bearing trees and static electricity connected

Chemistry
1 answer:
Pavlova-9 [17]2 years ago
5 0

Answer: Static electricity will help in seed dispersal in cone bearing seeds.

Explanation:

Static electricity is the stationary electric charge produced by the friction. The static electricity can be produced by the turbulence or air currents in the storm clouds. This is responsible for the cause of lightening phenomena.

The cone bearing seeds exhibit cones that are hard and woody in nature.  The static electricity due to the effect of lightening generate electrical shock which breaks open the cone and disperse the seeds. Thus the static electricity is important for seed dispersal in cone bearing trees.

A 0.1 gram sample of an unknown liquid is vaporized completely at 70 degrees C to fill a 750mL flask. The pressure is 0.05951atm
Deffense [45]

Answer:

The molar mass of the liquid 62.89 g/mol

Explanation:

Step 1: Data given

Mass of the sample = 0.1 grams

Temperature = 70°C

Volume = 750 mL

Pressure = 0.05951 atm

Step 2: Calculate the number of moles

p*V = n*R*T

n = (p*V)/(R*T)

⇒ with n = the number of moles gas = TO BE DETERMINED

⇒ with p = The pressure = 0.05951 atm

⇒ with V = The volume of the flask = 750 mL = 0.750 L

⇒ with R = The gasconstant = 0.08206 L*atm/K*mol

⇒with T = the temperature = 70 °C = 343 Kelvin

n = (0.05951 *0.750)/(0.08206*343)

n = 0.00159 moles

Step 3: Calculate molar mass

Molar mass = mass / moles

Molar mass =0.1 gram /  0.00159 moles

Molar mass = 62.89 g/mol

The molar mass of the liquid 62.89 g/mol

Why do we not know yet if we live in multiverse
kherson [118]

The people of he world believe and they don't believe.

I,myself, think we do land don't live in multiverse.

Why: Because in science I hear that there are many universes out there that need to b explored.

Not: Because if we did, don't you think that Astronauts and the U.S. would try and find different universes.

I hope I helped you!:)
