The rock gets melted down and then re-formed over and over again.
Answer:
Explanation:
Hello,
In this case, given that one mole of glucose, contains six moles of oxygen (subscript), we can also see it contains twelve moles of hydrogen (subscript), therefore, the moles of hydrogen in the sample are computed by:
Best regards.
Answer:
0.553 J/g°C
Explanation:
From the question given above, the following data were obtained:
Heat (Q) required = 99.7 J
Mass (M) = 34.7 g
Temperature change (ΔT) = 5.20 °C
Specific heat capacity (C) =?
Thus, we can obtain the specific heat capacity of titanium as follow:
Q = MCΔT
99.7 = 34.7 × C × 5.20
99.7 = 180.44 × C
Divide both side by 180.44
C = 99.7 / 180.44
C = 0.553 J/g°C
Therefore, the specific heat capacity of titanium is 0.553 J/g°C.
This problem may easily solved by applying the conservation of mass, which states that the total mass before and after a change is constant because mass can neither be created nor destroyed.
We know that water consists of only hydrogen and water, and that there are no other reactants except hydrogen and oxygen. Thus:
Mass of reactants = Mass of product
mass of hydrogen + mass of oxygen = mass of water
4 + mass of oxygen = 36
mass of oxygen = 32 grams
Isotopes are basically from the same element. In terms of subatomic particles of the element, the isotopes will then basically have the same number of protons. The electrons also have to be same in number given that the elements are in neutral charges.
We are then left with neutrons, which is one of the subatomic particles residing in the nucleus of an atom.
Thus, the answer is NEUTRONS.
