The value of gravitational acceleration on the surface of mars is 0.377 times that on earth. if your mass is 85 kg, your weight on earth is 830 n (m * g = 85 kg3 * 9.8 m/s2 = 830 n). what would be your approximate mass and weight on mars?

Mass on Mars = 85 kg

Weight on Mars = 314.041 N

Explanation:

Given that:

Value of the gravitational acceleration on surface of the Mars is 0.377 times that on the Earth.

Which means that:

Mass does not depend on gravity

Thus, mass on Mars is same as Mass of Earth = 85 kg

Weight on Mars = 85 kg × 3.6946 m/s² = 314.041 N

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
