Answer:
0.144M
Explanation:
First, let us write a balanced equation for the reaction. This is illustrated below:
HNO3 + KOH —> KNO3 + H20
From the equation,
nA = 1
nB = 1
From the question given, we obtained the following:
Ma =?
Va = 30.00mL
Mb = 0.1000M
Vb = 43.13 mL
MaVa / MbVb = nA/nB
Ma x 30 / 0.1 x 43.13 = 1
Cross multiply to express in linear form
Ma x 30 = 0.1 x 43.13
Divide both side by 30
Ma = (0.1 x 43.13) /30 = 0.144M
The molarity of the nitric acid is 0.144M
Answer:
iron, graphite,NaCl solution etc are some examples of good conductor of electricity
Answer:
An oxygen molecule consists of two oxygen (o2) atoms bound together and a water molecule consists of two hydrogen atoms and one oxygen atom (h20). H20 has a higher evaporation temperature than oxygen therefore it stays a liquid at room temperature unlike oxygen. Both have oxygen atoms.
Yes the particles are larger than 10,000 Angstroms which allow it to be separated by filtration
Answer:
The correct answer is option (6).
Explanation:
A molecule is group of atoms of same or different kinds of element.
In carbon monoxide there is a single carbon atom and single oxygen atom. Hence, a molecule.
Compound is defined as a chemical specie which is made by the combination of different atoms.
As we can see from the chemical formula of carbon monoxide is made up of two atom of different elements that is carbon and oxygen.
A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass. They have definite set of properties.
1 mole of carbon combined with 0.5 moles of oxygen gas to give carbon monoxide gas.
