582 ml is the volume of gas.
Answer:
Explanation:
Using the ideal law of gases, the kinetic theory of gas can be stated as
PV = nRT
Here P is the pressure and it is given as 1.2 atm, V is the volume, which we need to find. Then R is the gas constant and T is the temperature while n is the concentration present.
As per the give question, P = 1.2 atm, T = 140 K and n = 0.5 moles, R = 8.314
V =
V =
So 582 ml is the volume of gas.
Answer:
The correct answer is reaction will achieve equilibrium by forming more products and will move in left to right direction.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
- If Q >
, then the equilibrium will shift in left direction or in backward direction.the reaction will move back to the formation of reactants from the product
- If Q <
Answer:
<u>an element with a large number of valence electrons and a large atomic radius</u>
Explanation:
Electronegativity means a tedency when an atom attracts bonding electrons in a covalent bond situation.
» If an atom has many valency electrons [ <em>empty</em><em> </em><em>orbitals</em><em> </em><em>i</em><em>n</em><em> </em><em>o</em><em>u</em><em>t</em><em>e</em><em>r</em><em>m</em><em>o</em><em>s</em><em>t</em><em> </em><em>s</em><em>h</em><em>e</em><em>l</em><em>l</em><em> </em>], it has difficulty in attracting electrons hence electronegativity low.
» If an atom is large, its nuclear attraction force of incoming electrons is low hence low electronegativity.
