I’m pretty sure the answer would be B.
Answer:
Graduated cylinders are designed for accurate measurements of liquids with a much smaller error than beakers. They are thinner than a beaker, have many more graduation marks, and are designed to be within 0.5-1% error. ... Therefore, this more precise relative of the beaker is just as critical to almost every laboratory.
Explanation:
hope this helped!
In his experiment, Thompson shot a beam of alpha particles at a sheet of gold foil<span>, and only a few of the particles were deflected or reflected right back. Before the experiment, the plum pudding model was believed to be true, where a cloud of positive ions distributed throughout the inner space of an atom. Thompson concluded that there's a high-energy dense nucleus at the center of an atom.</span>
Salinity has units of grams NaCl or salt per kilogram solution. We can use the density given and the molar mass of the salt to convert from salinity to molarity. We do as follows:
( 5.6 g / kg ) ( 1.03 kg / L ) ( 1 mol / 58.44 g ) = 0.0987 mol NaCl / L
the equation balanced is
3 PbI4 + 4 CrCl3 → 3 PbCl4 + 4 CrI3
