Answer: 38.111111
Explanation: (100.6°F − 32) × 5/9 = 38.111°C
For alpha and beta decay it does because the proton number changes.
During gamma, there is no change of identity, just energy
Answer:
0.93 mol
Explanation:
Given data:
Number of moles of Na atom = ?
Number of atoms = 5.60× 10²³
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
5.60× 10²³ atoms × 1 mol / 6.022 × 10²³ atoms
0.93 mol
Generally speaking the larger, more massive elements are less stable, like isotopes of elements. With this said, they are less likely to react since they will become heavy and unstable. This is why chlorine is more reactive with other elements like sodium than astatine.
Answer:
B. Suspension
Explanation:
A suspension is an heterogenous mixture in which the large particles settle out when not disturbed, thus ,can easily be separated by filtration.
An example is a mixture of sand and water. When left for a while the sand particles are clearly visible at the bottom of the container if its transparent.
