Pick out the metals which can react with magnesium sulphate solution. Justify the answer.
calcium, aluminium, mercury, sodium, platinum, copper
Answers
Answer: aluminium, mercury , platinum and copper.
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
A general single displacement reaction can be represented as :
[tex]XY+Z\rightarrow XZ+Y[/tex]
Thus the metals which are more reactive than magnesium will react with magnesium sulphate solution.
The metals which are more reactive than magnesium are aluminium, mercury , platinum and copper.

The prefix "semi-" means "partly". Based on your knowledge of the properties of elements, which kind of element is most likely used to make semiconductors?
liquids
metalloids
metals
nonmetals
Answers
Answer:
metalloids
Explanation:
The kind of element most likely used to make semiconductors are the metalloids.
These elements have properties between those of metals and non-metals in that they are not truly metals and are partly non-metals.
Under certain conditions they show features of metals or non - metals. The class of these elements are the metalloids. They are used to make semiconductors which are major components of electronics.what charged particle is produced during ionic bonds
Answers
Answer:
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation or a positively charged ion. The atom gaining one or more electrons becomes an anion which is a negatively charged ion.
Find the number of moles if you have 1.2 x 1048 copper atoms.

Explanation:
From avogadro's number, we have that;
1 mole of atoms contain 6.022 × 10^(23) atoms
Therefore, 1.2 x 10^(48) atoms of copper will contain;
(1.2 x 10^(48) × 1)/(6.022 × 10^(23)) = 1.993 × 10^(24) moles

What takes place when a chemical change occurs
Answers
Answer:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Explanation:
hope this helps
When bonds between molecules or atoms are created, disrupted, or both, chemical changes result. This implies that a material is changed from one with a certain set of attributes into another with a different set of properties.
What is an atom ?Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent kind of hydrogen is neutron-free. The smallest component of ordinary stuff that makes up a chemical element is an atom.
An atom's nucleus is surrounded by an area of electrons. The electrical charge of every electron is negative one. Protons and neutrons, which together make up an atom's nucleus, are made of quarks.
The atoms in the reactants rearrange and link with one another differently to create one or more new products that vary from the reactants in several ways.
Thus, When bonds between molecules or atoms are created, disrupted, or both, chemical changes occur.

Explanation:
Neils Bohr in 1913 put forward his own model of the atoms based on the quantum mechanics originally developed by Planck.
He assumed the Rutherford's model and suggested that the extranuclear space consists of electrons in specific spherical orbitals around the nucleus. His predecessors and contemporaries did not give this perspective to the atomic model. The orbits/energy levels are designated by letters K, L, M, N .... The maximum number of electrons that can be accommodated by an energy level is 2n² where n is the principal energy level.Answer:

Answers
Answer:
The scale reads the tension in the string. The tension in the string is 100 N. This is the force the string must exert up on either of the 100-N weights at either end of the string.
Nothing is moving, nothing is accelerating, so the net force on the spring is zero. Likewise, the net force on either of the 100-N weights is also zero. But that is another question. The spring scale does not measure the net force. The spring scale simply measures the tension, the magnitude of the force exerted by the string.

Uranium has three common isotopes. If the abundance of 234U is 0.0054%, the abundance of 235U is 0.7204% and the abundance of 238U is 99.2742%, what is the average atomic mass of uranium?
Answers
Answer:
237.9 amu
Explanation:
Given data:
Abundance of U-234 = 0.0054 %
Abundance of U-235 = 0.7204%
Abundance of U-238 = 99.2742%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass / 100
Average atomic mass = (0.0054×234)+(0.7204×235) +(99.2742×238) /100
Average atomic mass = 1.2636+ 169.294+ 23627.2596 / 100
Average atomic mass = 23797.8172/ 100
Average atomic mass = 237.9 amu.
