Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
Answer:
A. to cure human diseases
Explanation:
The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.
Example,
ᵇₐX
Where;
b = Mass Number
a = Atomic Number
X = Symbol
For Hydrogen Isotopes:
1) Protium: 1 Proton , 0 Neutron
¹₁H
2) Deuterium: 1 Proton , 1 Neutron
²₁H
3) Tritium: 1 Proton , 2 Neutron
³₁H
Answer:
+6
Explanation:
We are given;
We are required to determine the oxidation number of S in the compound.
We need to know that;
- The total oxidation number of this compound is Zero
- Oxidation number of Ba metal is +2
- Oxidation number of Oxygen atom is -2
- There is 1 atom of Ba, 1 atom of S and 4 atoms of O in the compound.
Therefore; assuming oxidation number of S is x
Then, (1× 2) + (1 × x) + ( 4 ×(-2)) = 0
2 + x - 8 = 0
x = 6 or +6
Thus oxidation number of Sulfur in BaSO₄ is +6.
