Answer:
The correct answer would be - 1/2 ft.
Explanation:
if the scale is 1:4,000
It shows that the model plane will fly 1ft above the ground., the original plane flyes 4,000ft above the ground,
Now, if the plane flies 2,000ft above the ground, this is half times as the scale given, then the model plane will also fly half times as the number from the scale.
1/2*1ft = 1/2ft.
Now, we also can do it as:
4000 ft equivalent to 1 ft.
2000ft equivalent to x
x = 1ft*(2000ft/4000ft) = 1ft*1/2 = 1/2ft.
Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)
