The reaction that should be followed is
Na2SO4 + C<span>a(NO3)2 --> CaSO4 + 2NaNO3</span>
first calculate the limiting reactant
mol Na2SO4 = 0.075 L (<span>1.54×10−2 mol / L) = 1.155x10-3 mol
mol Ca(NO3)2 = 0.075 L (</span><span>1.22×10−2 mol / L) = 9.15x10-4 mol
so the limiting reactant is the Ca(NO3)2
so all of the Ca2+ will be precipitated, percentage unprecipitated = 0.00 % </span>
Answer: -
¹⁰B has the same number of neutrons as ⁹Be
Explanation: -
Mass number of ⁹Be = 9
Atomic number of ⁹Be = 4
Number of neutrons of ⁹Be = mass number - atomic number
= 9 - 4 = 5
Mass number of ¹⁰B = 10
Atomic number of ¹⁰B= 5
Number of neutrons of ¹⁰B= mass number - atomic number
=10 - 5 = 5

Nitrogen fixation is the process that makes atmospheric nitrogen available to plants by mutualistic and free-living bacteria. The process is undertaken by the rhizobium bacteria that live in root roots of plants such as legumes. The mutualistic relationship is that the plant supplies the bacteria with a habitat in which to live, water, and nutrients, and the bacteria supply nitrogen for making plant proteins.
Answer:
Explanation:
by using litmus papaer it will turn into red if solutions is acidic
and into blue if it's basic
by using Magnesium ribbon. Magnesium do not react with bases so hydrogen gas will produce when Magnesium is dipped in an acidic solution
