Answer:
because it helps you to understand what’s the most important thing on your ”to - do” list and helps you to get it done. the higher up it is on your list, the more you have to prioritize it to get it dome.
Answer:
1.7L of water.
Explanation:
Given parameters:
Volume of hydrogen gas = 1.7L
Unknown:
Volume of water produced = ?
Solution:
A synthesis reaction is one in which two compounds or molecules combines together to give a product or products.
Synthesis of water from hydrogen gas is represented by the equation below:
2H₂ + O₂ → 2H₂O
We clearly see that;
2 mole of hydrogen gas gives 2 mole of water as the product;
From Gay-lussac's law of combining volume "when gases react, they do so in volumes which bear a simple ratio to one another and to the volume of the product if gaseous, temperature and pressure remaining constant".
2H₂ + O₂ → 2H₂O
2 volumes of hydrogen gas will produce 2 volumes of water
1.7L of hydrogen gas will also produce ; 1.7L of water.
(2) the number of reactant particles and the number of product particles
(3) the rate of the forward reaction and the rate of the reverse reaction
(4) the mass of the reactants and the mass of the products
b. [H+] is equal to [OH−].
c. [H+] is less than [OH−].
d. [H+] is greater than [OH−].
2 - The nucleus of an atom is split apart.
3 - An atom gains an electron from another atom.
Which reaction(s) most likely release the greatest amount of energy?
1
2
1 and 3
2 and 3
Answer: Option (b) is the correct answer.
Explanation:
When an atom shares electrons with another atom then it results in the formation of covalent bond.
Whereas when an atom transfer electrons from one atom to another then it results in the formation of ionic bond.
When nucleus of an atom splits then it represents nuclear fission reaction and energy is released during this process.
For example,
Therefore, we can conclude that out of the given options, the nucleus of an atom is split apart most likely release the greatest amount of energy.
