You have been given an orange liquid and told to describe its properties.
chubhunter [2.5K]

Answer:

The correct answer would be - observing with the help of five senses.

Explanation:

To find and describe the physical properties of the given substance or the solution or liquid students can observe using their five senses. By looking at the liquid one can find its state and color, by smelling students can find the odor of the sample, by touching it one can observe and describe the texture.

Fluidity can also be measure by the touch if the solution is viscous or free-floating. By using a thermometer and using a graduated cylinder one can find the temperature at room temperature and the weight of substance respectively.

Determine the hybrid orbital of this molecule.
Pavel [41]

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

<h3>What is hybridisation?</h3>

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

In this compound, sp^3 a hybrid orbital makes I-O bonds. Due to sp^3hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of IO^{3-} the ion is pyramidal.

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

The easiest way to determine whether a process is exothermic or endothermic is to note the change in temperature in a calorimete
Kryger [21]

Answer:

In the calorimeter, water is the <u>exothermic</u>. The salt LiCI, which will dissolve, is the <u>endothermic</u>. The final temperature of the water after the dissolution of LiCI was <u>lower</u> than the initial temperature, meaning the process is <u>exothermic</u>. In the microscopic view of the disspolution of LiCI, water molecules were seen to move <u>slowly</u> as they <u>gained </u>energy.

Explanation:

Exothermic is a process in which heat is released during the process. Endothermic reactions absorbs heat from surrounding during a chemical process. The dissolution of salt into water is an exothermic reaction. During this process heat is release and water molecules are broken down which are surrounded by salt ions.
