Answer: Solids
Explanation:
Solids have a definite volume and structure. These are comprised of atoms, ions, and molecules closely packed together giving a confined structure to the solids. The particles are bound with strong force of attraction. The particles in the solid are arranged in an repeated, orderly, and three dimensional pattern. Depending upon the substance of the solid the particles within the solid can be ions, atoms, and can be molecules.
Answer:
D
Explanation:
because in a decay series a daughter nuclei may be stable or decay itself. that starts a decay series
In a titration, for an acid to neutralize a base, at the equivalence point, there should be an equal number of moles of H+ and OH-.
Moles of OH- can be found by multiplying the concentration of the base by the volume. (You will need to keep in mind the stoichimetric coefficients if the strong base is Ca(OH)₂, Ba(OH)₂, or Sr(OH)₂.
Moles of OH- = moles of H+
(0.253 M) * 0.005 L = 0.01000 L * c
c = 0.1265 M
The concentration of HBr is 0.127 M.
the answer is A.) because the scientific method is used to answer problems.
This is the steps,
STEP 1: ask a question
STEP 2: state your hypothesis
STEP 3: conduct an experiment
STEP 4: analyze your results
STEP 5: make a conclusion
