Answer: Option (c) is the correct answer.
Explanation:
A monomial is defined as an algebraic expression in which there is only one term present.
For example, 3x is a monomial.
A binomial is defined as an expression where there will be two terms present. For example, is a binomial.
A polynomial is defined as an algebraic expression which contains more than two terms.
For example, is a polynomial.
Thus, we can conclude that the given expression is a polynomial.
Answer:
From gas laws (pressure law and Boyles law), the pressure exerted by a gas depends on Temperature of the gas and volume of the container.
Explanation:
• P → Pressure exerted by the gas.
• T → Temperature of the gas.
• V → Volume of the container.
• from the expression, pressure exerted by the gas is directly proportional to temperature of the gas and inversely proportional to the volume of the container.
Answer : The equilibrium concentration of NO is, 0.0092 M.
Solution :
First we have to calculate the concentration of NO.
The given equilibrium reaction is,
Initially conc. 0 0 0.1576
At eqm. (x) (x) (0.1576-2x)
The expression of will be,
By solving the term, we get:
Neglecting the 0.0839 value of x because it can not be more than initial value.
Thus, the value of 'x' will be, 0.0742 M
Now we have to calculate the equilibrium concentration of NO.
Equilibrium concentration of NO = (0.1576-2x) = [0.1576-2(0.0742)] = 0.0092 M
Therefore, the equilibrium concentration of NO is, 0.0092 M.
