Lab: Plate Boundaries and Movement Lab Report.

Chemistry
1 answer:
Nastasia [14]2 years ago
8 0

A Plate Boundaries and Movement Lab Report is a report that shows the records of all the data relating to the movement of Plate Boundaries and their movements.

<h3>What are Plates in this context?</h3>

A tectonic plate is also described or referred to as a Lithosperic Plate. In Geography, it is described as a slab of rock that is not shaped regularly.

In most cases, it comprises continental and oceanic lithosphere.

<h3>Why is it crucial to record the movement of plates and their boundaries?</h3>

Plate Boundaries and their movement are largely linked to volcanic activities and earthquakes. This means that they can be used to predict when any of the above-mentioned events may happen.

a sample of cobalt (specific heat of Co=0.418J/G C )at 100.0 C is dropped into a calorimeter containing 500.0 mL of water at 21.
Alex17521 [72]

Answer:

m_{Co}=6998g=7.0kg

Explanation:

Hello there!

In this case, according to this equilibrium temperature problem, we can set up the following equation to relate the mass, specific heat and temperature change:

Q_{Co}=-Q_{w}\\\\m_{Co}C_{Co}(T_f-T_{Co})=-m_{w}C_{w}(T_f-T_{w})

Thus, we solve for the mass of cobalt as shown below:

m_{Co}=\frac{-m_{w}C_{w}(T_f-T_{w})}{C_{Co}(T_f-T_{Co})} \\\\m_{Co}=\frac{-500.00g*4.184J/g\°C(67.1\°C-21.1\°C)}{0.418J/g\°C(67.1\°C-100\°C)} \\\\m_{Co}=6998g=7.0kg

Best regards!

What is the ph of a 0. 571 m solution of hydrosulfuric acid, h2s?
Ray Of Light [21]

pH is the potential of the hydrogen in the aqueous solution. The pH of the hydrosulfuric acid is 0.6.

<h3>What is pH?</h3>

pH is the hydrogen or the hydronium ion concentration in the aqueous solution. The formula to calculate pH is given as,

\rm pH = \rm - log [H^{+}]

Since hydrosulfuric acid is diprotic the concentration of the hydrogen ion will be:

\begin{aligned} \rm [H^{+}] &= 2 \times 0. 571 \;\rm M \\\\&= 1.142\end{aligned}

Now, pH is calculated as:

\begin{aligned} \rm pH &= \rm - log [H^{+}]\\\\&= \rm - log [1.142]\\\\&= 0.06\end{aligned}

Therefore, 0.6 is the pH of the hydrosulfuric acid solution.
