Answer:
The chemical reactions are depends up on the temperature. Temperature is a measure of motion of the particles, which increases by supplying thermal heat energy. According to the Kinetic molecular theory, if the reaction happens between two compounds, they collide with enough energy to overcome the activation of energy barrier.
The kinetic energy of the particles increases with increase in temperature. This results in collision being more energetic and therefore more likely to be able to overcome the activation barrier. The rate of chemical reactions increases with more collision of molecules.
<em>So, the temperature is the important parameter to increase the rate of reactions. </em>
The specific gravity is the ratio of the substances density to that of water at 4 degrees Celsius. With this, it is conclusive that the density of iron is 7.87 g/cm³. The volume occupied by the iron is the quotient when mass is divided by density,
V = m / D = (7 g) / (7.87 g/cm³) = 0.89 cm³
Therefore, 7 grams of iron occupies approximately 0.89 cm³.
There’s no diagram
- I need to see the diagram so I can answer the question
Answer:
True.
Explanation:
The magnetic axis and rotation axis of both of these planets are misaligned that why it is right to say that the magnetic fields of both Uranus and Neptune are highly tilted relative to their rotation axes and significantly offset from the planet's centers.
The rate of change of velocity
