Answer:
A decomposer
Explanation:
An organism like a fungus or a worm breaks down dead, nonliving matter which ends up giving nutrients back into the soil.
Answer: 2.186 m
Explanation:
formula for molality: (mol solute)/(kg solvent)
Na2CO3 = solute
510g Na2CO3 * ( 1 mol / 106 g) = 4.811 mol solute
ethylene glycol = solvent
2.2 * 10^3 g * ( 1 kg / 1000 g) = 2.2 kg
(4.811/2.2) = 2.186
Answer:
Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
Explanation:
The types of bonds present are:
a) Ethane : single bond
b) Ethene : double bond (one sigma one pi)
c) Ethyne: triple bond (one sigma and two pi bonds)
More the number of bonds lesser the bond length.
Thus the order of bond length of carbon-carbon bond will be:
Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)
Combined gas law is
PV/T = K (constant)
P = Pressure
V = Volume
T = Temperature in Kelvin
For two situations, the combined gas law can be applied as,
P₁V₁ / T₁ = P₂V₂ / T₂
P₁ = 3.00 atm P₂ = standard pressure = 1 atm
V₁ = 720.0 mL T₂ = standard temperature = 273 K
T₁ = (273 + 20) K = 293 K
By substituting,
3.00 atm x 720.0 mL / 293 K = 1 atm x V₂ / 273 K
V₂ = 2012.6 mL
hence the volume of gas at stp is 2012.6 mL
Answer:
f = frequency = 590,000 Hz ===> 59×10^4 Hz
λ = Wavelength = ?
c = Speed of light in a vacuum = 3 × 10^8 m/s
** Hz = 1/sec
