In this problem, Charles' law is applicable since constant pressure with varying volume and temperature are given. Charles' law derived from ideal gas law is expressed as \frac{ V_{1} }{ T_{1} }=  \frac{ V_{2} }{ T_{2} }. Subsituting V1=556 cm3, T1=278 K and T2=231 K, V2 or the new volume is 462 cm3.

Which of the following expressions best represents a second order rate law?
Ksivusya [100]
I think the correct answer would be C. The expression that would best represent a second order rate law would be r =k[X][Y]. Reaction with this rate law are those that depend on the concentration of two first order reactants or a second order reactant.

When a person says "I think that between an elephant and a monkey that jumped off the cliff, both of them will hit the ground at
Fofino [41]

Option A is correct. When a person says "<em>I think</em><em> that between an elephant and a monkey that jumped off the cliff, both of them will hit the ground at the same time."</em> the person is stating his Hypothesis

A hypothesis is an explanation proposed or given based on a piece of evidence that is limited.

It is useful at the beginning of an investigation because it serves as the building block for an impending fact or law.

From the statement, we can see that the person is not too sure of the information provided since he "thinks". <em>He said, </em><em>"I think</em><em> that between an elephant and a monkey that jumped off the cliff, both of them will hit the ground at the same time." </em>

<em />

Hence we can conclude that the person is stating a hypothesis.

Law and theory are incorrect because they are already proven facts.

[OH-] for a solution is
solong [7]

Answer:

B = basic

Explanation:

Given data:

[OH⁻] = 5.35×10⁻⁴M

pH = ?

Solution:

pOH = -log[OH⁻]

pOH = - [5.35×10⁻⁴]

pOH = 3.272

it is known that,

pH + pOH = 14

pH = 14- pOH

pH = 14 - 3.272

pH = 10.728

The acidic pH is range from zero to less than 7 while 7 pH is neutral and above 7 the pH is basic. So, the given solution is basic.

Describe the difference between a reaction that occurs spontaneously and one that does not
lidiya [134]
2.B. Describe the difference between a reaction that occurs spontaneously and one that does not. Spontaneous chemical reactions release energy and use that energy to power itself; non-spontaneous chemical reactions need to absorb energy, which they can't absorb their own energy that they don't even have.
