Answer:
The correct answer is option B.
Explanation:
The molecular formula of iron(II) acetate tetrahydrate.;
Atomic mass of iron = 55.84 amu
Atomic mass of carbon = 12.01 g/mol
Atomic mass of oxygen = 16.00 amu
Atomic mass of hydrogen = 1.01 amu
Molecular mass of iron(II) acetate tetrahydrate:
The closest option to 246.02 amu is 245.9 amu.
So, the correct answer is option B.
Answer:
E
Explanation:
So this question tests your understanding of mole:mole ratios.
So looking at the equation we see for every 3 O2 there's 4 NH3, we can even word it like for every 4 mol of NH3 that reacts you need 3 moles of O2. This gives us the mole:mole (mole to mole) ratio of 3 mol O2/ 4 mol NH3.
Now since you have 3.5 moles of NH3 you can use the ratio from above to convert it to O2 by simply 3.5molNH3 * 3mol O2/4mol NH3 ------> 2.625mol O2
The answer you are looking for i believe is kingdom
There are 3 aroma.
There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains *3* atoms.
The correct option is:
The latent heat of vaporization of water is given by option D. 22,590J
Latent heat of vaporization:
Latent heat of vaporization is energy required to change 1 kg of liquid to gas at atmospheric pressure at its boiling point.
Also, Latent heat is the energy released or absorbed during a phase change.
Energy released during phase change is Exothermic process.
Whereas energy absorbed during phase change is Endothermic process.
Q=mL
Q= Latent heat
m= mass= 10 g
L= Latent heat of vaporization= 2,259 J/g
Putting the values in the above equation:
Q=10*2259
Q=22590 L
