Answer:
5.6L
Explanation:
Given parameters:
number of moles = 0.25mol
pressure on gas = 1atm
temperature = 273K
Gas constant R = 0.0821Latm/molK
Unknown:
Volume of gas = ?
Solution:
Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.
It is mathematically expressed as;
PV = nRT
where P is the pressure
V is the volume
R is the gas constant
T is the temperature
n is the number of moles
All the parameters are in the appropriate units and we simply solve for the volume of the gas;
1 x V = 0.25 x 0.0821 x 273
V = 5.6L
Answer: Flexible springs
Explanation:
The atoms in an element or compound are bonded together by bonds which keeps the atoms together.
The bonds is stiff but it proves some flexibility for the movement of the atoms so that they can react and form different types of substances.
The bonds between the atoms act like flexible spring which keeps two or more atoms together and flexible for reacting.

Answer:
D.the movement of air currents by conversation cells
Answer: Two smaller molecules join together after a water molecule is removed from between them. Energy is absorbed for bond formation: because energy is absorbed to make bonds, synthesis reactions are energy absorbing reactions.
