Answer:
The second process can occur without a net influx of energy from some other process C6H12O6+6O2-->6CO2 +6H2O
Explanation:
Energy is stored in form of ATP and the inverse reaction is a process of photosynthesis and it is responsible for the storage of energy.
This is cellular respiration.
Sugar and oxygen are provided by eating and breathing.
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
Answer: Physical change: It is reversible process and we can get back to orginal material. Best example is the interconversion of ice into water which inturn into vapour.
Chemical changes are irreversible and we can't get back the original material. Example combustion of coal, rusting of iron
Explanation:
1. Electrolysis of molten MgCl2 is chemical change since we can't get back MgCl2 after Electrolysis and new materials are formed.
2. It is an example rusting of iron comes under chemical changes.
Answer:
the nuclear envelope disappears
Explanation:
Answer: particles become ions when you remove electrons from a neutral atom to get a positive ion or adding ions to a neural atom to get a negative ion.
