A graduated cylinder has 33.5 mL of water. A piece of metal is added to the water and the new volume is now 46.2 mL. If the metal has a mass of 16.25 g, what is its density

The density of metal is 1.28g/ml

Explanation:

To calculate the density, we use the equation:

Density of metal = ?

Mass of metal = 16.25 g

Volume of metal = volume of water displaced = (46.2 - 33.5 )ml  = 12.7 ml

Putting values in above equation, we get:

The density of metal is 1.28g/ml

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
