The missing part of the equation is found to be 4/2He. Option A
<h3>What are nuclear equations?</h3>
The term nuclear equations have to do with the type of equation in which one type of nucleus is transformed into another sometimes by the bombardment or loss of a particle.
Now the full equation ought to be written as 7/3Li + 1/1H -----> 4/2He + 4/2He. This is because the total mass on the left is 8 and the total charge on the left is 4.

There are 6.02 × 10²³ formula units of CaCl2 in 111 g CaCl2. Details about formula units can be found below.
<h3>What is a formula unit?</h3>
Formula unit refers to the empirical formula of an ionic compound for use in stoichiometric calculations.
According to this question, there are 111g of CaCl2. The formula units can be calculated by multiplying the number of moles by Avogadro's number.
no of moles in CaCl2 = 111g ÷ 111g/mol = 1mol
Formula units of CaCl2 = 1mol × 6.02 × 10²³ = 6.02 × 10²³ formula units.
Therefore, there are 6.02 × 10²³ formula units of CaCl2 in 111 g CaCl2.

Incomplete question. The remaining part reads;
Choose the correct words or phrases to complete the sentences.
Global winds occur due to
<u>1. Choose...</u>
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
over a large area and this forms
2. Choose...
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
caused by cool and warm air.
Answer:
<u>1. d. uneven heating</u>
<u>2. b. convection currents</u>
Explanation:
1. What Beto should know is that as the earth moves and rotates around the sun, some parts of the Earth receive more sunlight and others less, which then leads to uneven heating over a large area of the earth.
2. This uneven heat then forms a convection current containing varying patterns of air spreading to various parts of the globe.
