The enthalpy of vaporization of H2O is higher than the enthalpy of fusion of H2O, therefore vaporizing the same mass of H2O would require more heat/energy than melting the same mass of H2O.
Answer:
6L
Explanation:
<em>if it's 3L per 200kPa</em>
then it would be;
4L per 300kPa
5L per 400kPa
6L per 500kPa
that's how i'd work it out in my head, hope it helps, but not sure though!
anything that turns red litmus paper to blue it is an acid and vice versa is true
Missing question:
A. All carbon atoms are identical.
B. An oxygen atom combines with 1.5 hydrogen atoms to form a water molecule.
C. Two oxygen atoms combine with a carbon atom to form a carbon dioxide molecule.
D. The formation of a compound often involves the destruction of one or more atoms.
Answer is: B and D.
A is correct because Daltan stated: All atoms of a given element have the same mass and other properties that distinguish them from the atoms of other elements.
C is correct because atoms combine in simple, whole- number ratios to form compounds, B is incorrect because ratio is not simple, whole number.
D is incorrect because according to Dalton. atoms can't be created or destroyed.
Answer:
A good experimental hypothesis can be written as an if, then statement to establish cause and effect on the variables. If you make a change to the independent variable, then the dependent variable will respond
