Explanation:
H2CO3 --------------------------> H2O + CO2
The reaction above is a decomposition reaction showing how the carbonic acid that is H2CO3 decomposed into H2O and CO2. The study of how reactants react(that is the amount in which they react) in order to form a product (and the amount of product formed) is known as the stoichiometry.
H2CO3 which is the reactant has three oxygen atoms which are all directly bonded to the carbon atom. One of the oxygen atom is bonded doubly to the carbon atom.
CO2 and H2O are the products. The CO2 is linear, O=C=O with the two oxygen atoms bonded doubly each to each carbon atoms. The H2O is bent.

Answer:
477 °C
Explanation:
Step 1: Given data
- Initial pressure (P₁): 1.0 atm
- Initial temperature (T₁): 27 °C
- Final pressure (P₂): 2.5 atm
Step 2: Convert 27 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 27 + 273.15 = 300 K
Step 3: Calculate the final temperature (T₂)
If we assume constant volume (before the can explodes) and ideal behavior, we can calculate the final temperature using Gay-Lussac's law.
T₁/P₁ = T₂/P₂
T₂ = T₁ × P₂/P₁
T₂ = 300 K × 2.5 atm/1.0 atm = 750 K
In Celsius,
°C = K - 273.15 = 750 - 273.15 = 477 °C
Answer:
predators are controlling the population of the species who are below them in the food pyramid . Also if the population of the preys decrease it will alternatively reduce the predator population .therefore the predator prey relationship balance an eco system.
Answer:
neutrons
Explanation:
Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.
Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.
Mass number = Number of protons + Number of neutrons
Thus both C14 and C12 have same number of protons as they have same atomic number.
The difference in the mass number of both the isotopes is sue to the difference in the number of neutrons.
Atomic number = Number of protons = 6
For CC- 14, Number of neutrons = 14 - 6 = 8
For C 12, Number of neutrons = 12 - 6 = 6
