Answer:
An alloy is the combination of metals homogeneously.
Explanation:
Alloys can also include other elements in combination with metals e.g carbon and Iron forms steel.
Alloys find a host of application in various industries and domestic use.
Alloying of metals helps to improve the physical and chemical properties of such materials better.
Some materials are alloyed to improve their strength.
Alloying can help heat and electrical conduction of a substance.
Alloys can greatly prevent rusting and produce corrosion resistant metals.
Alloys can provide a better means for a material to be worked.
Alloys can be more durable than original materials.
Answer:
Flammability.
Explanation:
Chemical properties of a substance are properties of a substance that occur in the chemical reactions in which it is involved. These are the basis for the classification of substances, such as metals, halogens, acids, alcohols, alkenes, arenes, etc. A class of substances is characterized by chemical properties common to that group. Differences in the chemical and physical properties of substances allow the substance to be identified, and the components of a mixture of substances to be separated and purified.
The chemical properties of a substance are its chemical stability, reactivity, oxidizability, acidity, bromine number, polymerisability, flammability, toxicity, etc. These can be determined by chemical exposure.
0.5 = 1/2 = 2/4 = 4/8 = 8/16 = 16/32…
0.75 = 3/4 = 6/8 = 12/16 = 24/32…
Then you can easily find the fractions in between are: 5/8, 9/16, 11/16, 17/32, 19/32, 21/32, 23/32...
Answer:
0.01 M
Explanation:
The chemist is performing a serial dilution in order tyo obtain the calibration curve for the instrument.
First we must obtain the concentration of the solution in the 250ml flask from
C1V1 = C2V2
Where;
C1 = concentration of the stock solution
V1 = volume of the stock solution
C2 = concentration of the diluted solution
V2= volume of the diluted solution
2.61 × 10 = C2 × 250
C2 = 2.61 × 10/250
C2 = 0.1 M
Hence for solution in 100ml flask;
0.1 × 10 = C2 × 100
C2 = 0.1 × 10/100
C2 = 0.01 M
