A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42

Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42

Newtons. With what force does the scale push back up against her feet?

Answers

Answer:

The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.

Okay.. so I guess this is how it goes:

1. Rainforest
2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra

Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..

Answer: The balanced equation will be

6H2 + N2 → 2NH3

Explanation:

First step is to balance nitrogen

ie, H2 + N2 → 2NH3

Second step is to balance hydrogen accordingly

ie, 6H2 + N2 → 2NH3

This is the perfect balanced equation.

What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.

Answers

Answer: Linear

Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.
