Answer:
894 deg K
Explanation:
The computation is shown below:
Given that
V1 denotes the initial volume of gas = 2.00 L
T1 denotes the initial temperature of gas = 25 + 273 = 298 K
V2 denotes the final volume of gas = 6.00 L
T2 = ?
Based on the above information
Here we assume that the pressure is remain constant,
So,
V1 ÷ T1 = V2 ÷ T2
T2 = T1 × V2 ÷ V1
= (298)(6) ÷ (2)
= 894 deg K
In biology the term extinct is used for species which are no longer alive. so here Ava is correct because a species has died out and is not longer alive.
Endangered species are those which are on the urge of being extinct, means they are in danger so the term "endangered"
Ava can also elaborate the terms by taking examples
Dinosaurs are extinct species. They are no longer alive or not found in any part of world. So they are called as extinct.
The term can be used for animal or plant species.
Answer: a) 0.070 moles of oxygen were produced.
b) New pressure due to the oxygen gas is 2.4 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = 2.7 atm
V = Volume of gas = 700 ml = 0.7 L
n = number of moles = ?
R = gas constant =
T =temperature = 329 K
Thus 0.070 moles of oxygen were produced.
When the 700 mL flask cools to a temperature of 293K.
The new pressure due to the oxygen gas is 2.4 atm
B.compound Because compound is when two element are combined or joined chemically
