Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = 
= 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = 
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = 
= 0.01mole
So,
Mass = 0.01 x 32 = 0.36g

<h3>What is Invasive species?</h3>
- An introduced organism that overpopulates and damages its new environment is referred to as an invasive species.
- Even though the majority of introduced species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.
- Invasive species are one of the largest issues our natural environments have ever faced.
- Invasive species have the potential to proliferate rapidly in the absence of their natural predators, displacing native species, destroying ecosystems, and incurring high costs.
- This increase is frequently attributed to growing global trade, manufacturing specialization, and linkages to previously remote areas.
- Additionally, the extension of existing imported specie's ranges is made possible by climate change.

Answer:
Adaptation
Explanation:
Some beaks made it easier for the type of food that bird was trying to get, for example the sharper the beak the better it could possible break a nut
