We have to convert 0.18 km into feet
First, we need to know the conversions:
1 inch = 2.54 cm (exact)
1 pound = 454 g
1 Liter = 1.0b quarts
1 feet = 12 inches
1 galion = 4 quarts
1 pound = 16 ounces
0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft
Answer: 590 ft (2 significant figures)
Answer:
= 2113.44 kJ
Explanation:
When 1 mole of CH4 (g) burns in excess oxygen -714.0 kJ of heat is released.
For 47.50 g;
molar mass of CH4 = 16.042 g/mol
Number of moles of CH4
= 47.5 g /16.042 g/mol
= 2.96 moles
Therefore;
1 mole = -714.0 kJ
Heat change for 2.96 moles
= 2.96 moles × -714.0 kJ
= 2113.44 kJ
Answer:
Balanced forces are those two forces acting in opposite directions on an object, and they are equal in size. Anytime if there is a balanced force on an object, the object stays still or it continues moving at the same speed and in the same direction is called a balanced force.

Answer: 1. The average atomic mass of chlorine is 35.453u
2. The average atomic mass of copper is 63.5 u
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
1. For chlorine:
2. For copper:
