Fofino [41]3 years ago
5 0
Write and balance the equation

C7H16 + 11 O2 -> 7 CO2 + 8 H2O

According to the stoichiometry of the reaction one mol of heptane will react with 11 mol of molecular oxygen, then

1.42 mol O2 x 1 mol heptane/ 11 mol O2 = 0.129 mol

In the graph above for the dissociation of a strong acid, why do the bars for H3O+ and A- have the same height as the bar for HA
dimaraw [331]

Answer:

The concentration of HA is the same as concentration of H3O+ and A- produced.

Explanation:

The dissociation equation is given below:

HA(aq) + H2O (l) —> H3O+(aq) + A-(aq)

From the reaction above, we can see that the acid is monoprotic acid i.e it has only 1 ionisable hydrogen atom.

Now, from the balanced equation, we can see that the acid produced equal concentration of H3O+ and A-.

This account for the reason why the bars for H3O+ and A- have the same height as the bar for HA.

Find the volume of a gold ring that has a mass of 12.00 grams. The density of gold is 19.30 g/mL. The volume is
kozerog [31]

Answer:

<h3>The answer is 0.622 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass = 12 g

density = 19.30 g/mL

We have

volume =  \frac{12}{19.30}  \\  = 0.62176165...

We have the final answer as

<h3>0.622 mL</h3>

Hope this helps you

How did satellite tracking allow biologists to study the green sea turtle?
Rasek [7]

<u>Answer:</u>

It helped biologists collect data on when and where turtles travel.

<u>Explanation:</u>

Green sea turtles need to be conserved so the biologist take help of satellites in order to track down green sea turtles.

The tracking of green sea turtles can be done by the help of satellites as satellites send a signal whenever these turtles come to surface of water to breathe which can then be used to prevent the turtles from getting caught by poachers.
