Answer:

A direct relationship between 2 quantities or variables may be a description of a specific approach that the 2 quantities or variables act with each other. once a amount or variable encompasses a direct relationship with another amount or variable, we are able to describe it employing a mathematical expression.

Complete the following equations (note that the equations are not balanced). Use the activity series if necessary. An activity s
umka21 [38]

The equation which we are required to complete can be completed as follows;

  • AgNO3 + KCl ==> KNO3 + AgCl

<h3>Electrochemical series;</h3>

Most substitution reactions involve displacement of metals and non-metals.

The possibility of a substitution reaction to occur is sometimes dependent on the order of preference of the metals in the activity series.

On this note, In the reaction between AgNO3 and KCl, potassium, K displaces silver, Ag and the products of the reaction are; KNO3 and AgCl

Zigmanuir [339]

Answer:

\boxed{\text{0.780 atm}}

Explanation:

Hermione is pretty smart. She realizes that, according to Dalton's Law of Partial Pressures, each gas exerts its pressure independently of the others, as if the others weren't even there.

She shows Ron how to use the Ideal Gas Law to solve the problem.

pV = nRT

She collects the data:

V = 1.00 L; n = 0.0319 mol; T = 25.0 °C

She reminds him to convert the temperature to kelvins

T = (25.0 +273.15) K = 298.15 K

Then she shows him how to do the calculation.

p \times \text{1.00 L} = \text{0.0319 mol} \times \text{L}\cdot\text{atm}\cdot\text{0.082 06 K}^{-1}\text{mol}^{-1} \times \text{298.15 K}\\\\1.00p = \text{0.7805 atm}\\\\p = \textbf{0.780 atm}\\\\\text{The partial pressure of the nitrogen is } \boxed{\textbf{0.780 atm}}

Isn't she smart?

Which type of property can be observed only by changing a substance into a different substance
Nana76 [90]

Chemical Property

<u>Explanation:</u>

When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.

* its identity changes

*its reactivity changes

*reactivity towards water, air and many other substances will change

*its chemical composition changes

and all these changes occurs due to the chemical properties.

If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.
