Answer:
AlCl3.Structure 2 can be classified as both a Brønsted–Lowry and a Lewis base.
Explanation:
Let us recall that a Lewis acid is a lone pair acceptor while a Lewis base is a lone pair donors.
A Brownstead-Lowry acid is a proton donor while a Brownstead-Lowry base is a lone pair acceptor.
NH3 functions as a Lewis base because it can donate it's lone pairs in coordinate covalent bonding.
It can also accept a proton thereby acting as a Brownstead-Lowry base in the formation of the NH4+ ion.
2. They taste sour, are electrolytes, and react with active metals to produce hydrogen.
3. You should NEVER taste unknown chemicals because many are poisonous and can destroy body tissue.
4. Most often dyes are used to detect acids. The dyes will turn a certain color which indicates the presence of an acid.
10. You can use litmus to detect wether a solution is a base or an acid.
11. The most common bases I can think of would be: baking soda, laundry detergent, or soaps.
12. Antacids work by neutralizing the acids in your stomach.
13. When an acid and base are mixed together, they produce a salt.
14. Normally pH meters are used, but you can also calculate the pH using math. (yuck)
15. The pH scale measures how acidic or basic a substance is. It ranges from 0-14, with 7 being neutral.
17. pH is very important to the environment as it helps us measure and monitor for safe water conditions. A rise or fall from the average water pH level can indicate chemical pollution.
18. Salt is formed when an acid and base react with each other. It then has a cation of the base, and anion of the acid.
I hope those helps!! (:
Answer: take out your phone, record things in slow motion mode, and watch it after?
or just try imagining it.
or tell everyone to walk slowly for scientific purposes
yeah thats all i have

Answer:
0.24 g/mL
Explanation:
The density of an object is given by the ratio between its mass and its volume:
where
m is the mass of the object
V is its density
In this problem, we have:
m = 7.0 g is the mass of the object
The volume of an irregular shaped object can be measured by putting it into water, and by measuring the difference in water volume.
In this case,
is the initial volume of water
is the final volume of water
So the volume of the object is
Therefore, the density of the object is:
circle represents a female
square represents a male
if its colored then it shows that they have the trait of whatever disease or mutation or something that you are studying
the horizontal line represents that they are married or a marriage (husband and wife)
the vertical line represents the connection between the parents and children
several children are represented through a bracket and a veritcal line
