Answer:
matter cannot be created nor destroyed
Explanation:
Answer:
They are produced from rocks (parent material) through the processes of weathering and natural erosion.
Explanation:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
Answer: C. The non metal
Explanation:-
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The nomenclature of ionic compounds is given by:
1. Positive ion or metal is written first.
2. The negative ion or non metal is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
For example: 
, cesium is metal having an oxidation state of +1 called as 
cation and bromine 
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral called as cesium bromide.
Answer:
Approximately 206 grams.
Explanation:
How many moles of sulfuric acid 
are there in this solution?
.
The unit for concentration "
" is equivalent to mole per liter. In other words, 
. For this solution, the concentration of is 
.
.
What's the mass of that 
of ?
Start by finding the molar mass 
of .
Relative atomic mass data from a modern periodic table:
- H: 1.008;
- S: 32.06;
- O: 15.999.
.
.
.
In other words, the chemist shall need approximately 206 grams of to make this solution. As a side note, keep in mind that the 206 grams of also take up considerable amount of space. Therefore it will take less than 5.00 L of water to make the 5.00 L solution.
In Chemistry, the dissociation constant describes a dissociation reaction in which a compound is broken up. It measures how likely the reaction will occur. For example for reaction AB -> A + B, the dissociation constant is equal to concentration of A x concentration of B / concentration of AB at equilibrium.
