Answer:
lithium lithium (or 2lithium) + oxygen ->
Explanation:
Your welcome
The degree to which a liquid resists flowing is called viscosity
This has multiple answers can you be more specific
Explanation:
Nuclear fusion produces more energy with less radioactive waste compared to nuclear fission process.
- In nuclear fission, a radioactive decay occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons with the release of energy.
- Nuclear fusion occurs when small atomic nuclei combines into larger ones with the release of a large amount of energy.
- Instability of a nuclide is enough to start up a nuclear fission reaction. In some instances, a heavy nuclide is bombarded with another nuclide.
- In nuclear fusion, the activation energy required to start up is very great.
Nuclear wastes emanating from nuclear fusion process is least compared to that of nuclear fission.
Nuclear fusion produces more energy compared to nuclear fission process.

<span>To find the volume of the plate without accounting for the hole firstly
V = (15.0 cm)(12.5 cm)(0.250 cm) = 46.875 cm^3
and the volume of the hole is
(pi)(1.25 cm)^2(0.250 cm) = 1.2272 cm^3
we will subtract the volume of the hole from the rest 45.648 cm^3
the multiply this by the density of the alloy to find the mass
(8.80 g/cm^3)(45.648 cm^3) = 401.701 g.
0.044% of this is Si, so (0.00044)(401.701 g) = 0.17675 g is silicon.
by the number of atoms and using average atomic mass of silicon and Avogadro's number to find the number of silicon atoms:
(0.17675 g)(1 mol/28.0855 g)(6.022E23 atoms/1 mol) =3.794E21atoms of Si
3.10% of these are Si-30:(0.0310)(3.794E18 atoms)=1.176E20 atoms of Si-30 and with two significant figures, 1.2E20 atoms.
hope this helps
