Answer:
Nuclear scientists continue to expand the periodic table as they detect new elements. ... Scientists create heavy elements by bombarding two lighter elements that together add up to the mass of the desired new element. One of the elements is stationary and thus called the target.
Answer:
The molarity of the solution is 0.048 M (option B)
Explanation:
<u>Step 1: </u>Data given
Sucralfate has a molar mass of 2087 g/mole
mass = 1g
volume = 10 mL
<u>Step 2: </u> Calculate moles of sucralfate
Number of moles = mass of sucralfate / Molar mass of sucralfate
Number of moles = 1 g / 2087 g/mole = 4.79 * 10^-4 moles
<u>Step 3:</u> Calculate molarity
Molarity = Number of moles / volume
Molarity = (4.79 * 10^-4 moles) / (10 *10^-3 L)
Molarity = 0.0479 M ≈ 0.048 M
The molarity of the solution is 0.048 M (option B)
Explanation:
PbI2 is the precipitate.................
<span>The rare earth elements include the lanthanide series, scandium and yttrium. They are a set of seventeen chemical elements in the periodic table. They really are not that rare but they occur together in nature and are hard to separate from one another.</span>
