In terms of the most common type of salt, sodium chloride, NaCl is the chemical formula of this salt,
Answer:
If the density is less than one, an object will float. If it is more than one, that object will sink.
A) 24 m; B) 2.0 × 10^2 m^2; C) 0.46 s; D) 53 L
<em>Part A) Length of court
</em>
Length = 78 ft × (12 in/1 ft) × (1 m/39.37 in) = 24 m
<em>Part B) Area of court
</em>
Width = 27 ft × (12 in/1 ft) × (1 m/39.37 in) = 8.23 m
<em>A = lw</em> = 24 m × 8.23 m = 2.0 × 10^2 m^2
<em>Part C) Time of serve
</em>
Time = 24 m × 1 km/1000 m × 1 h/185 km × 3600 s/1 h = 0.46 s
<em>Part D) Volume of paint
</em>
<em>A = lw</em> = 78 ft × 27 ft = 2100 ft^2
<em>V</em> = 2100 ft^2 × (1 gal/150 ft^2) × (3.785 L/1 gal) = 53 L
When the supply of air or oxygen is poor
