At the current rate, a graph of carbon dioxide produced by fossil fuels over time would slope upward slope downward be horizontal be vertical

Slope upward

Explanation:

The amount of carbon dioxide increases daily due to the increased use of petroleum fuels in diesel engines in the industries and by motor car users. The number of petroleum cars increases as their affordability increases. Use of LPG as domestic fuel has increased. These practices increase the amount of carbon dioxide in the atmosphere.

The rate of CO₂ production increases as these activities increases daily.  

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table
