A circle graph, or a pie chart or graph, would be the type of graph that is best used when showing the <span>percentage of reactant molecules that collide during a reaction in a graphical representation. In addition, the circle graph mainly consists of a circle being divided into parts proportional to the whole.</span>

Answer:

Circle Graph

Explanation:

A scatter plot shows distribution of some numbers or properties versus another property. So it should be used for analysis of distribution or probability of something.

Stem and leaf plot are used when we have to show splitting of a stem ( a number) into leaves (another numbers).

So for percentage of reactant molecules colliding cannot be represented by scatter plot or stem and leaf plot.

In a circle graph or pie chart, we divide a circle (considering it to be 100%) into different parts based on fraction or percentage of each component.

For percentage of reactant molecule, we can divide the whole circle into two parts. One part showing the percentage of non reacting molecules and other part showing the percentage of reactant molecules undergoing collision.

mr_godi [17]

Answer: A plot of the natural log of the concentration of the reactant as a function of time is linear.

Explanation:

Since it was explicitly stated in the question that the half life is independent of the initial concentration of the reactant then the third option must necessarily be false. Also, the plot of the natural logarithm of the concentration of reactant against time for a first order reaction is linear. In a first order reaction, the half life is independent of the initial concentration of the reactant. Hence the answer.

3. Hydrogen reacts with nitrogen to produce ammonia according to the equation:
lys-0071 [83]

Mass of ammonia produced : 121.38 g

<h3>Further explanation</h3>

Given

Reaction

3H₂(g) + N₂(g) ⇒ 2NH₃(g)

100g of N₂

Required

Ammonia produced

Solution

mol of N₂ :

\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{100}{28}\\\\mol=3.57

From the equation, mol ratio of N₂ and NH₃ = 1 : 2, so mol NH₃ :

\tt \dfrac{2}{1}\times 3.57=7.14~moles

mass of NH₃(MW=17 g/mol) :

\tt mass=mol\times MW\\\\mass=7.14\times 17\\\\mass=121.38~g

What does the host mean when he says that the acid has "donated a proton" to the water?
weqwewe [10]

Answer:

Option B

Explanation:

As Brønsted-Lowry theory states, acids are the ones that can donate protons.

When a proton is donated, it is released to become medium more acidic.

HCl is a strong acid.

HCl (l) + H₂O (l)  →  H₃O⁺ (aq) +  Cl⁻(aq)

These always reffers to strong acid where the dissociation is 100% completed.

In a weak acid, dissociation is not 100% complete, that's why we have an equilibrium.

HA (l) + H₂O (l)  ⇄  H₃O⁺ (aq) +  A⁻(aq)                   Ka
