Answer:
The answer is
<h2>6.0 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
density = 2.7 g/mL
mass of aluminum = 16.2 g
The volume is
We have the final answer as
<h3>6.0 mL</h3>
Hope this helps you
Answer:
Electronegativity increases across the period on a periodic table.
Explanation:
Electronegativity is the ability of an atom to attract electron to itself.
All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.
This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.
Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.
This makes them highly reactive and combine readily with other elements.
The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.
Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.
Answer:
The correct answer is option 2.
Explanation:
Colligative property is defined as property which depends upon only on the numbers of particles of solute dissolved in definite amount of solvent, It do not depend on the nature of the solute.
For example : NaCl solution with 0.4 molal will show same colligative properties as a that of the glucose solution with 0.04 molal concentration.
The following are the examples of colligative property:
1. Relative lowering of vapor pressure.
2. Osmotic pressure
3. Elevation in boiling points
4. Depression in freezing point
Answer:
b consumers eat producers
Explanation:
In a food chain, the consumers are living organisms that eat organisms from a different population. Examples are herbivores like goats.
Producers make their own food in the food chain. Examples are plants.
The relationship between consumer and producers is hence that consumers consume / eat producers. Goats eat grass.
The correct option is;
b consumers eat producers
