1) Chemical equation.
2) Types of reaction.
In the reaction above, we can see that two different compounds get together to form a new compound. <em>This is called a synthesis or a combination.</em>
Decomposition: A compound is broken down into simpler compounds.
Combustion: A compound containing Carbon and Hydrogen combines with oxygen.
Double replacement: Positive and negative ions in two compounds switch places.
What pH scale number represents a neutral.
The answer is 7
Answer:
278 mL x 0.038 M = 10,564 mmol.
Using the molair mass of Fe2(SO4)3 to convert mmol to grams:
10,564 mmol / 1000 x 399,88 g/mol = 4,22 g Fe2(SO4)3.
Answer:
Explanation:
It is given that pH of .
Now, molality of , M=
Now, we know,
...1
Here C is concentration.
Now,
Putting all values in equation 1.
We get,
Hence, this is the required solution.
Answer:
An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Picture 1.8 Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.
Explanation:
...
