The specific heat capacity of liquid water is 4.18 J/g oC. Calculate the quantity of energy required to heat 1.50 g of water from 26.5oC to 83.7oC. (Ignore significant figures for this problem.)

The quantity of heat required is 358.644 J.

Explanation:

Given: Specific heat capacity =

Mass = 1.50 g

Formula used to calculate heat energy is as follows.

where,

q = heat energy

m = mass

C = specific heat capacity

= initial temperature

= final temperature

Substitute the values into above formula as follows.

Thus, we can conclude that quantity of heat required is 358.644 J.

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.  

i think it is true since you can test the answer and can use observations to complete it.
