Solutions are made up of two non reacting species called solute and solvent. The amount of solute in solvent is known as concentration of that solute. Concentration is often measured in Molarity. Molarity is the amount of solute dissolved in 1 dm3 of solution. Answer to your question is as follow;
Answer: Balance, multiply, find ratio
Explanation:
Balance the equation to be able to multiply correctly and accurately, multiply, and this will give you the molar ratio
Answer:
A
Explanation:
because the object's velocity had no acceleration between time intervals
The isotope is identified as 58 Fe²⁺, where 58 is the mass number of the isotope.
Explanation:
In this problem, there is difference in the number of protons and electrons, but the electron number should not vary in a stable isotope. As isotopes are meant to have difference in number of neutrons leading to change in the mass number. So this means, in the present case the isotope is in oxidized state as the number of electrons is less than the number of protons. This indicates that the isotope is in +2 oxidation state, since the difference in the number of protons and electrons is 2.
Then as an isotope will be formed by varying in the number of neutrons for the elements in periodic table. So from the number of protons we can confirm the atomic number of the element. As the atomic number is given as number of protons in case of oxidized element, the atomic number of 26 in the present case will be related to Fe element in the periodic table.
Hence the isotope will be Fe in +2 oxidation state and having the atomic number as 26 and mass number as 26+32 = 58. So there is a change in the mass number of the isotope of Fe from 56 to 58.
Thus, the isotope is identified as 58 Fe²⁺, where 58 is the mass number of the isotope.
Answer:
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. ... The value of the radius may depend on the atom's state and context.
