Answer:
Explanation:
Hello!
In this case, since this calorimetry problems can by analyzed by figuring out that the heat lost due to the combustion of C6H12O6 is gained by the water and the calorimeter which undergo the mentioned temperature rise, we can write:
Thus, by plugging in the given data, we obtain:
Next, we compute the moles of C6H12O6 by using its molar mass (180.18 g/mol) as shown below:
Thus, the value for q of the reaction turns out:
Best regards!
Are you referring to this statement?
<span>The attraction between various combinations of atoms will produce chemical bonds which form molecules.
If you are, then the statement stated above expresses truism.
Thus, the answer is letter a. TRUE</span>
Answer:
Gravitational force is also decreases.
Explanation:
Gravitational force is directly proportional to the mass of an object and inversely properly to the distance between their centres. Directly means if one increases the other automatically increases or if one decreases, the other also decreases. There is a direct relationship between mass and gravitational force so if mass of the bodies decrease, the gravitational force is also decreases.
Non living things are abiotic so sand is abiotic
