The change in state from Liquid ➡ gas describes the process of evaporation.
<u><em>Answer= </em></u><em>An amine in which the nitrogen atom is directly bonded to three carbons of any hybridization </em><u><em>and</em></u><em> Alcohol is attached to a saturated carbon atom which has three other carbon atoms attached to it.</em>
- Tertiary amine (3o amine): An amine in which the nitrogen atom is directly bonded to three carbons of any hybridization which cannot be carbonyl group carbons. General tertiary amine structure. C = any carbon group except carbonyl
- A tertiary alcohol is a compound in which a hydroxy group, ‒OH, is attached to a saturated carbon atom which has three other carbon atoms attached to it

Answer:</h3>
28.17 %
<h3>
Explanation:</h3>
In the question we are required to determine the percent by mass of nitrogen in (NH₄)₃PO₄.
- To calculate the percent by mass of an element in a compound we use the formula;
- % by mass =(Mass of the element÷ Relative formula mass of the compound)100
In this case;
- Atomic mass of nitrogen is 14.0 g/mol
But; There are three nitrogen atoms in (NH₄)₃PO₄.
Therefore; Mass of nitrogen in (NH₄)₃PO₄ = 14.0 × 3
= 42 g
The relative formula mass of (NH₄)₃PO₄ = 149.0867 g/mol
Thus;
% by mass of N = (42 g ÷ 149.0867 g/mo)× 100%
= 28.17 %
Therefore, the % by mass of N is (NH₄)₃PO₄ is 28.17%
Answer:
Chemical science arises in the seventeenth century from the studies of alchemy popular among many of the scientists of the time. The basic principles of chemistry are considered to be collected for the first time in the work of the British scientist Robert Boyle: The Skeptical Chemist (1661).
Answer:
A melting ice cube.
Explanation:
Since we are adding thermal energy (we are adding heat), we raise the temperature of an object.
Condensation on a mirror is incorrect because we are cooling the temp.
Inflating a balloon is incorrect because we aren't transferring thermal energy.
Tearing paper is incorrect because we aren't applying thermal energy.
