Answer: Option (4) is the correct answer.
Explanation:
It is known that density is mass divided by volume.
Mathematically, Density = 
Since, density is directly proportional to mass. So, more is the mass of an element more will be its density.
Mass of magnesium is 24.305 g/mol.
Mass of barium is 137.327 g/mol.
Mass of beryllium is 9.012 g/mol
Mass of radium is 226 g/mol.
Hence, radium has more mass therefore it will have the greatest density at STP.
Answer:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

Answer:
Explanation:
Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.
OR
Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them

Ethyl acetate and methyl benzoate combination of reactants will produce ethyl 3-phenyl-3-oxopropanoate when treated first with an alkoxide and then with a diluted aqueous acid
<h3>Ethyl acetate</h3>
One of the most straightforward carboxylate esters is ethyl acetate. The simplest is methyl formate, a former Molecule of the Week. Most people enjoy the taste and aroma of the colorless liquid's sweet, fruity scent.
Ethyl acetate was initially created by combining ethanol and acetic acid, as one might anticipate. The process was the traditional Fischer esterification, which dates back to 1895 and is catalyzed by an acid. This commercial synthesis is still the most popular. A different approach is the Tishchenko reaction, in which acetaldehyde disproportionately reacts with base to form alcohol and acid, which subsequently esterify naturally.
