Answer:
0.08kg
Explanation:
Given parameters:
Temperature of water = 100°C
Quantity of heat released = 180414.08J
Unknown:
Quantity of water condensed = ?
Solution:
This is simple phase change process without any attendant change in temperature.
To solve this problem, use the formula below;
H = mL
H is the heat released
m is mass
L is the latent heat of condensation of water = 2260 kJ/kg
Insert the parameters and solve;
180,414.08 = m x 22.6 x 10⁵ J/kg
m = 
= 0.08kg
Answer:
Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.
Its symbol is the Greek letter chi: χ
The higher the electronegativity, the greater an atom's attraction for electrons.
Below is a periodic table of electronegativity: the lighter the shade of green, the higher the electronegativity. Gray means no value is known. (Click image for larger view that shows electronegativity values.)
Explanation:
Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in.
Lets take one element from Group 6A, Let it be oxygen, The electronic configuration of Oxygen is as follow,
O = 8 = 1s², 2s², 2px², 2py¹, 2px¹
There are 6 electrons in the valence shell of elements present in Group 6A. The unpaired electrons in 2px and 2py are involved in forming covalent bond, while the pair of electrons in 2s and 2px are unshared and act as lone pair of electrons.
Result:
There are TWO unpaired electrons present in the ground state of Group 6A elements.
Answer:
The three states of matter are the three distinct physical forms that matter can take in most environments: solid, liquid, and gas. In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates, and neutron stars.
