Answer:
![\fbox {(2) 4.9}](https://tex.z-dn.net/?f=%5Cfbox%20%7B%282%29%204.9%7D)
Explanation:
Applying the Ideal Gas Equation :
![\boxed {PV = nRT}](https://tex.z-dn.net/?f=%5Cboxed%20%7BPV%20%3D%20nRT%7D)
Finding n :
- n = 64 g / 32 g/mole (<u>Oxygen is diatomic</u>)
- <u>n = 2 moles</u>
Solving for P :
- P = 2 × 0.0831 × 300 / 10 (<u>Temp. should be converted to K</u>)
- P = 60 × 0.0831
- P = 4.9
∴ The pressure inside the flask in bar is 4.9.

Molecular equation: Chemical equation in which molecular formula of reactants and products are written
Complete ionic equation:Chemical equation in which ionic from if reactants reactants and products are written along with spectator ions (ions present on both sides of equation).
Net ionic equation :Chemical equation in which only ions of those reactant are written which giving product without spectator ions (ions present on both sides of equation).

Answer: The molecule
is expected to have a dipole moment of zero.
Explanation:
The product of magnitude of the charge calculated in electrostatic units is called dipole moment.
Formula for dipole moment is as follows.
Dipole moment = Charge (in esu)
distance (in cm)
Non-polar molecules have zero dipole moment.
For example,
is a non-polar molecule so its dipole moment is zero.
is a polar molecule so it will have dipole moment.
is a polar molecule so it will have dipole moment.
has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.
Thus, we can conclude that the molecule
is expected to have a dipole moment of zero.
Answer:
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
