C. If 62.9 g of lead (II) chloride is produced, how many grams of lead (II) nitrate were
melomori [17]

Answer:

Mass = 76.176 g

Explanation:

Given data:

Mass of lead(II) chloride produced = 62.9 g

Mass of lead(II) nitrate used = ?

Solution:

Chemical equation:

Pb(NO₃)₂  +  2HCl     →     PbCl₂ + 2HNO₃

Number of moles of lead(II) chloride:

Number of moles = mass/molar mass

Number  of moles = 62.9 g/ 278.1 g/mol

Number of moles = 0.23 mol

Now we will compare the moles of lead(II) chloride with Pb(NO₃)₂ from balance chemical equation:

                            PbCl₂        :          Pb(NO₃)₂

                               1             :             1

                             0.23         :            0.23

Mass of Pb(NO₃)₂:

Mass = number of moles ×  molar mass

Mass = 0.23 mol × 331.2 g/mol

Mass = 76.176 g

Think of Earth's shape. How does the shape of Earth affect the amount of heat different
diamong [38]

Answer: The Earth is an oblate spheroid which is more elongated along the equator.

Regions along the equator receives more amount of direct sunlight from the sun causing higher temperatures along the region. While places along the poles receives less amount of heat since heat is scattered in a larger area due to the shape of the Earth around the poles.

Explanation: So places along the equator experiences higher temperature due to the direct hit of sunlight. And places along the polar regions experiences cooler temperature since it receives less amount of sunlight.
