The radiator is next to the triangle, receiving the sound waves and they travel through the radiator up to the other room. She can't hear the sound if the triangle isn't struck near the radiator because the sound waves aren't going through the radiator, and are not able to reach her through the wall. Hope this helps!

what is an empirical formulaWhat is the percent composition by mass of nitrogen in (NH4)2CO3 (gram-formula mass = 96.0 g/mol)?
Margarita [4]

Answer:

Percentage composition = 14.583%

Explanation:

In chemistry, the emprical formular of a compound is the simplest formular a compound can have. It shows the simplest ratio in which the elements are combined in the compound.

Percentage composition by mass of Nitrogen

Nitrogen = 14g/mol

In one mole of the compound;

Mass of Nitrogen = 1 mol * 14g/mol = 14g

Mass of compound = 1 mol * 96.0 g/mol = 96

Percentage composition of Nitrogen = (Mass of Nitrogen /  Mass of compound) * 100

percentage composition = 14/96   * 100

Percentage composition = 0.14583 * 100

Percentage composition = 14.583%

Chemistry : the atomic number of an element is 73. Is this paramagnetic or diamagnetic? :) ...?
Finger [1]
<span>Paramagnetic, an easy way to check is to see if it is the last element within the orbital and you can do that simply by looking at the periodic table. The s orbital has two, the p has 6 so on and so forth. Some elements are considered diamagnetic if they are almost completely full. </span>
