Answer:
independent- test variable
manipulated - outcome variable; if needed, there could be changes.
Explanation:
knowledge
Answer:
The first and most obvious pattern I see is that all gas giants have an atmosphere mainly made up of hydrogen
The second thing I notice is that all the rocky planets have a significant amount of Nitrogen in their atmospheres except Mercury.
The third thing I notice is that all planets have one element that makes up 75% or more of its atmosphere except Mercury.

The amount of heat lost by the copper is 2402.4 J.
To Calculate the amount of heat lost, we use the formula below.
<h3>Formula:</h3>
- Q = cm(t₂-t₁)................. Equation 1
<h3>Where:</h3>
- Q = Amount of heat lost
- c = specific heat capacity of copper
- m = mass of copper
- t₂ = Final temperature
- t₁ = Initial temperature
From the question,
<h3>Given:</h3>
- m = 78 g
- c = 0.385 J/g°C
- t₂ = 120°C
- t₁ = 40°C
Substitute these values into equation 1.
- Q = 78(0.385)(120-40)
- Q = 2402.4 J
Hence, The heat lost by the copper is 2402.4 J

Ionic bonds are forces that hold together electrostatic forces of attractions between oppositely charged ions. Ionic bonds have an electronegativity difference greater than or equal to 2. Covalent bonds have an electronegativity difference that is less than 2.
