To determine the mass of xenon tetrafluoride, we need to know first the number of fluorine atoms present in <span>oxygen difluoride. We need to convert first the mass into moles then make use of the relation of the elements from the chemical formula. Then, use the avogadro's number to convert it to number of atoms. Then, we do the reverse of the steps above but this time for </span><span>xenon tetrafluoride.
25.0 g OF2 ( 1 mol / 54 g ) ( 2 mol F / 1 mol OF2 ) ( 6.022 x10^23 atoms F / 1 mol F ) ( 1 mol / 6.022x10^23 atoms) ( 1 mol XeF4 / 4 mol F ) (207.3 g / 1 mol XeF4) = 47.99 g XeF4</span>
<span>Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different
number of neutrons. They differ in the number of neutrons that is why
they also differ in mass numbers. Since they have the same number of
protons, they have the same atomic number.
For instance, when the
nucleus of the isotope with a 68.926 amu, there are 30 protons and 39
neutrons in the nucleus. The best example for this is Zn (zinc-69
isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu
respectively.

Answer:
through the tree's fibers
Explanation:
the tree's leaves produce sugar that is transported through the tree's fibers. Sap also contributes means of transportation for these sugars.
Answer:
Carbon dioxide is a gas because the particles surrounding it are more spread out and free from each other. Water is a liquid because the particles are partially spread out and have a medium space to move around. And due to the room temperature, salt's particles can either be hot and move rapidly, or be cold and not move rapidly.
