B all of these will increase the strength of the magnet
The reactants are higher in energy than the products
Answer:
The nucleon number of given atom = 51
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
The mass number is also called nucleon number.
The nucleon number of given atom = number of protons + number of neutrons
The nucleon number of given atom = 25 + 26
The nucleon number of given atom = 51
Answer:
Saturated solution.
Explanation:
- Kindly see the attached image, the curve with brown line is for KClO₃, and according to the curve at 30
°C the solubility of KClO₃ per 100 g of water is 10 g.
So, 10.0 g of KClO₃ forms a saturated solution.
Hello!
The substances, ordered according to their dissolving time in water, are the following
Sugar Cubes > Granulated Sugar > Powdered Sugar
The difference between these substances is the degree of order. According to collision theory, for a substance to be dissolved, successful collisions between solvent molecules and solute molecules need to happen. as molecules are more ordered, successful collisions are less likely to happen, because atoms are fixed into a crystalline structure.
When the molecule is less ordered, successful collisions are more likely to occur, as the atoms can be impacted from different sides and aren't fixed into a given position.
As the degree of order increases, the dissolving time in water will be higher too, as more time would be required for successful collisions to happen. The most ordered substance is sugar cubes, followed by granulated sugar and powdered sugar, and that order is the same as the order for dissolving time.
Have a nice day!
