Iwill mark brainliest a spaceship orbiting earth flies to the moon. how is the gravitational force pulling on the spaceship related to the distance that the spaceship is from the earth? question 25 options: there is no gravity on the moon and therefore only the earth will exert gravitational force on the spaceship. the gravitational pull of the earth is constant and therefore the gravitational pull on would not change. as the distance from the earth increases, the gravitational pull on the spaceship would decrease. as the distance from the earth decreases, the gravitational pull on the spaceship would decrease

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
