true
That is false. Assuming an exothermic reaction, e.g., a fusion of hydrogen to helium:The total amount of mass before and after the reaction is the same. (Any energy leaving the atom has a mass equivalent.)The total amount of energy before and after the reaction is the same. (The energy was there previously, in the form of potential energy).
True volume is the amount of space occupied by an object. Who ever told you told you right, you did't ulgy
true
Glycoproteins give positive results for Molisch's test. This answer is true because Molisch test was a test for sugar.
The truth about the total amount of O2 and CO2 is that they have have the diffrent level of chaning over time.
Yes, total energy is always conserved in a closed system, according to the law of conservation of energy. Energy can change forms within a system (e.g., potential energy to kinetic energy), but the total amount of energy remains constant.
no.because hypotheses you want to test if it is true or not
TURE
No, even pregnancy tests have errors sometimes.
true
Yeah. sure, why not?
yes it is true
True
True
The OR function always results in a true when one input is true.
No, it is not always true that the total distance is equal to the displacement. Total distance is the sum of all path lengths travelled, while displacement is the shortest distance between the initial and final positions. In some cases, these two values may be equal, but not always.
