Look at the protons and electrons and rememeber metals want to get rid of electrons to be perfect. Nonmetals are wanting to take in. Metals are negatives in electrons. Opposite for nonmetals.
Answer:
Sodium
(Na)
Just count the electrons and search which atom it is.
Answer:
The molarity of the formed CaBr2 solution is 0.48 M
Explanation:
Step 1: Data given
Number of moles CaBr2 = 0.72 moles
Volume of water = 1.50 L
Step 2: Calculate the molarity of the solution
Molarity of CaBr2 solution = moles CaBr2 / volume water
Molarity of CaBr2 solution = 0.72 moles / 1.50 L
Molarity of CaBr2 solution = 0.48 mol / = 0.48 M
The molarity of the formed CaBr2 solution is 0.48 M
they are listed in order of decreasing number of moles
Hydrochloric acid (HCl) and brine both compound expect to be removed from the organic layer extracted with 1 m NaOH solution.
<h3>What is extraction?</h3>
Using a solvent, a component of interest is selectively removed from a mixture during extraction. The process has been utilized to form the phase separation with the solvent in one phase, and the solute to be present in another phase.
The extraction process can be differentiated based on the phase of the solute and solvent. For example, solid-liquid, liquid-liquid, solid-gas and others.
The extraction with the use of the NaOH forms the solute to lose an electron to the hydroxide of the NaOH and forms the layer of the negative acid. The use of Brine and HCl forms to bond with the organic layer and mediate the extraction process.
