Answer:
Hydrogen fuel cells do not produce any CO2 emissions during operation, even if their production is not necessarily carbon-free. This gives them an advantage over combustion engine vehicles, which can emit small amounts of poisonous carbon monoxide and require well-ventilated rooms for indoor use.
Answer:
,
, NaOH are all ionic compounds.
Explanation:
It is known that ionic compounds are the compounds in which one atom transfer its valence electrons to another atom. Hence, during this transfer partial opposite charges tend to develop on the combing atoms due to which strong force of attraction exists between the atoms.
An ionic bond is always formed between a metal and a non-metal.
For example,
,
, NaOH are all ionic compounds.
On the other hand, a compound formed due to sharing of electrons between the combining atoms is known as a covalent compound. Generally, a non-metal with same or different non-metal tends to form a covalent bond.
For example,
,
etc are all covalent compounds.
Thus, we can conclude that
, [tex]CH_3CH_2COONa, NaOH are all ionic compounds.
I can’t see it can your turn it a bit?
The balanced equation :
LiI(aq) + AgNO₃(aq) --> AgI(s) + LiNO₃(aq)
<h3>Further explanation</h3>
Given
Word equation
Required
Balanced equation
Solution
There are 3 ways to express a chemical equation:
- word equation
- skeleton equation
- balanced equation
Skeleton equation for reaction above :
LiI(aq) + AgNO₃(aq) ⇒ AgI(s) + LiNO₃(aq)
If we look at this reaction, all the cations and anions have a charge of 1 (+1 or -1) so the balanced reaction between the skeleton equation and the balanced equation is the same
