Cobalt is often used because it react to magnets while gold does not react to magnets.
Boyle's law gives the relationship between pressure and volume of gas. It states that for a fixed amount of gas at constant temperature, pressure is inversely proportional to volume of gas.
PV = k
where P - pressure, V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
substituting the values in the equation
0.947 atm x 150.0 mL = 0.987 atm x V
V = 144 mL
therefore new volume is 144 mL
Answer:
vacuum
Explanation:
vacuum is the form by which matter cant exist
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.
