If the density is 2 mL and the mass is 18 grams what is the density

Chemistry
1 answer:
amm18122 years ago
7 0

Given that,

Volume, d = 2 mL

Mass, m = 18 grams

We have to find the density. Density of an object is equal to mass per unit volume. It can be given by:

d=\dfrac{m}{V}\\\\d=\dfrac{18\ g}{2\ cm^2}\\\\d=9\ g/cm^3

So, the density is 9 g/cm³.

In equation δhsoln=δh1+δh2+δh3 which of the energy terms for dissolving an ionic solid would correspond to the lattice energy?
LekaFEV [45]
The dissolution of a solute in a solvent to form a solution usually occur in three steps, which are delta H1, delta H2 and delta H3. 
For dissolving an ionic solid, the lattice energy, which is the energy that is holding the ionic particles in place correspond to DELTA H2 and it is the energy that must be conquered. The higher the charge in the ionic solid, the higher the lattice energy. The lattice energy must be overcome in order for the solid to dissolve.

In the following redox reaction which is the oxidizing agent and which is the reducing agent? AlCl3 + Na NaCl + Al
horrorfan [7]

Answer :  Al

Explanation :

- For a given redox reaction there must be an oxidizing agent/(s) and a reducing agent/(s).

- the oxidizing agent is the substance that undergoes reduction process (gaining electrons or loss of oxygen atoms), meanwhile, the reducing agent is the substance that undergoes oxidation process (loss of electrons or gaining of oxygen atoms).

- In the reaction above, the oxidation number of (Al) in AlCl3 is (3+). However, the oxidation number of (Al) in the products is zero because it exists as a single element.

Therefore, changing from (3+) to zero means gaining of (3) electrons to neutralize the previously existing (3) protons on (Al) in AlCl3.

So Al is the oxidizing agent..

What is the most important role that water plays for living organisms
LuckyWell [14K]

(sounds weird but true XD) you get the point... here are a few things water does to our body:

- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.

- it trashes body waste and toxins (like i said above)

- it gives us nutrients and minerals

- it helps us to maintain out blood pressure

- it also helps to regulate our body temperature

- it transfers oxygen through the whole body

- it helps with digestion

-  weigh loss

- gives you energy ( thats why when your exercising you need to drink water every 15 min XD)

-prevents from you have a stinky breath *-*

- it helps with back-pain, headaches, heart health...etc

- it helps boost your immune system

- increases your brain power

so those are what i got for you about why water is important to us  :D
