Answer:

c_{Al} = 0.89\,\frac{J}{kg\cdot ^{\circ}C}

Explanation:

The heating process is modelled after the First Law of Thermodynamics:

Q = m \cdot c_{Al}\cdot \Delta T

The specific heat of the aluminium can is:

c_{Al} = \frac{Q}{m\cdot \Delta T}

c_{Al} = \frac{106.8\,J}{(10\,g)\cdot (12^{\circ}C)}

c_{Al} = 0.89\,\frac{J}{kg\cdot ^{\circ}C}

1. A sealed 2500mL flask is filled to capacity with 163g of a slimy green liquid. What is the density of the liquid?
Ksju [112]

Answer:

<h2>0.065 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

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

From the question we have

density =  \frac{163}{2500}  \\  = 0.0652

We have the final answer as

<h3>0.065 g/mL</h3>

Hope this helps you

The volume of solution in a test tube is measured to be 0.0067 liter. Which digits in the measurement are significant figures?
puteri [66]

<u>Given data:</u>

Volume of solution measured = 0.0067 L

<u>To determine:</u>

The number of significant figures

<u>Explanation:</u>

Significant figures are the number of digits that accurately describe a measured value.

As per the rules:

All non-zero digits are significant

Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant

Hence in the given value 0.0067, there are 2 significant figures (6 &7)

Put the following elements into five pairs of elements that have similar chemical reactivity: F, Sr, P, Ca, O, Br, Rb, Sb, Li, S
kirill115 [55]

Explanation:

Given elements:

  F, Sr, P, Ca, O, Br, Rb, Sb, Li, S

Elements with the same chemical reactivity will belong to the same group on the periodic table. This implies that elements in the same column will have the same reactivity;

  Li and Rb are both alkali metals in group 1

  Ca and Sr are both alkali earth metals in group 2

  F and Br are halogens in group 7

  O and S are group 6 elements

 P and Sb are both in group 5 on the periodic table

So these groupings show elements with the same chemical properties.
