Answer:
It conducts electricity
It conducts heat
Water is needed for rusting
Explanation:
Metals refer to elements that are found towards the left hand side of the periodic table of elements. They are found in groups 1- 13 and few of them are also found at the bottom of groups 14 and 15.
Now these metal have certain properties that are general to all of them. two of these properties listed among the options in the question are;
i) They conduct electricity
ii) They conduct heat
These properties apply to all metals universally.
Rusting is an electrochemical reaction in which hydrated iron III oxide is formed. In the electrochemical reaction, water in intimately involved in the process. Hence; oxygen and water are required for rusting to take place.
Answer:
This is an example of chemical change because the Kool aid dissolved and turned the water red
Al4C3 + 12H2O-----> 3CH4 + 4Al(OH)3
Answer:
DNA consists of molecules called nucleotides. Each nucleotide comprises a group of phosphates, a group of sugars and a base of nitrogen. The four forms of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The sequence of these bases defines the DNA instructions or genetic code.
According to the <span> chart represented above, I have determined the pair of atoms which has the greatest polarit and I am pretty sure that it is the first option from the scale :</span>A. Al-Si. I consider this to be correct due to their incredible difference <span>difference in electronegativity.
Hope it helps!</span>
