Answer:
24+74+61+29+38+27+68+54= 375
then divide by the number of numbers in this case 8 so;
375/8= 46.875
<h2>that's the median
46.875</h2>
Explanation:
Due to the presence of mobile or moving electrons in an atom they are good conductor of heat and electricity. Thus, the heat conduction and current conduction properties of metals are explained by its mobile electrons.
The other mentioned properties of metal are strength which can be explained by type of bonding within the metals, malleability explains the tendency of metals to be flattened into thin sheets, ductility explains the tendency to be stretched into wires, luster means the surface of metal is shiny and opacity is measure of impermeability that is to what extent they can pass light through them, metals are opaque, can not pass light through them or they are not transparent . All these properties are not because of mobile electrons in metals.
Therefore, correct properties are heat conduction and current conduction.
Answer: A.
Explanation: The patient's stress and anxiety would be eliminated. O High levels of radiation can diffuse through the patient's skin. Social contact would increase the effect of the radiation treatment.
The two stable isotopes of lithium are Lithium 6 with three neutrons and lithium 7 with four neutrons. Lithium 7 is the predominant isotope, about 92.5%.
Answer:
w/w means weight/weight
Therefore, in a 250 g of solution, 5% needs to be KCl,
i.e. 5% x 250 = 12.5 g of KCl is needed.
