We know that
Density = mass / volume
And volume = L*W*H (thickness)
First calculate the volume of foil as follows:
Density = mass / volume
Volume = mass / density
= 2.722 g/ 7.26 g/ cm^3
= 0.375 cm^3
And volume = = L*W*H (thickness)
0.375 cm^3 = 5cm*5 cm * thickness
Thickness = 0.015 cm
Answer:
How do we know what the temperature of the Earth was in the past? - One way to measure past temperatures is to study ice cores. Whenever snow falls, small bubbles filled with atmospheric gases get trapped within it. In some places, so much snow falls that the older layers become buried and compressed into ice, locking away air bubbles in ice sheets and glaciers
What is the relationship between CO2 (carbon dioxide) and temperature on Earth? - When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
What is the greenhouse effect? - the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Why are global sea levels rising? - Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.
Explanation:
- Electrons are negatively charged particles that orbits the nucleus.
- Chemical and physical properties of elements are usually determined by the number of electrons they posses.
- Electrons are the basis of the chemical changes in which atoms undergo.
- Chemical properties of atoms are a function of the number of electrons they posses.
- When atoms combine, they do so in order to attain stability.
- Combination of atoms involves the loss or gain or sharing of electrons between atoms.
- When atoms combine with one another, they form chemical bonds.
- These chemical bonds can be between two atoms or between molecules.
- The nature of the chemical bonds determines the physical and chemical properties of a host of compounds.
- For example, metallic bonds in metals is responsible for their conductivity and malleability.
- It is also responsible for the wide range of reactions they undergo.

The answer would be D because from my research it's the only one that didn't have a catalyst
