Use bond energies to calculate the enthalpy change for the following reaction. H2(g) + CO2(g) → H2O(g) + CO(g)

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

20 pts ‼️ an unmanned spacecraft travels to mars. mars has a lower strength of gravity than earth. where in the image is the spacecraft’s weight the greatest?
