Why is the melting of ice a physical change?

Chemistry
1 answer:
yan [13]3 years ago

<span>A physical change basically involves a change in physical properties. Some examples of physical properties include: texture, shape, size, color, volume, mass, weight, etc. 

The water melting has changed the shape and therefore it's physical properties, but the chemical nature of the water has not been altered.
So that's why it's a physical change, and not a chemical change.</span>

What did you observe in the reaction of phosphoric acid with the freshly cleaned zinc when compared with a piece just taken out
mash [69]

Answer:

The classification is mentioned below for the particular topic.

Explanation:

  • Whether we position 2 different beakers in such a single beaker through one clean edge of zinc-containing H₃Po₄ and another one with unflushed zinc.  
  • The zinc that was washed set to release hydrogen gas way quicker, unlike unventilated zinc.  

⇒      3Zn+2H_{3}Po_{4}\rightarrow Zn_{3}(Po_{4})_{2}+3H_{2}

  • Since fresh zinc complicates the cycle since, as a comparison to polluted zinc, there was little contact with either the reaction.

Match each element to the number of electrons in its valence shell
blondinia [14]

Answer: Be= 2, C =4,  Li = 1 and  B=3

Explanation:

The valence shell can be define as the outermost shell of an atom that contains the valence electrons.

Beryllium (Be), electronic configuration; 1s2 2s2, = 2 electrons in its valence shell.

Carbon (C), electronic configuration; 1s2 2s2 2p2, = 4 electrons in its valence shell.

Lithium (Li), electronic configuration; 1s2 2s1 = 1 electron in its valence shell.

Boron (B) , electronic configuration; 1s2 2s2 2p1 = 3 electron in its valence shell.

If the same materials are used to build a voltaic cell and an electrolytic cell, how would the chemical reactions compare?
nadya68 [22]
In the electrolytic cell, depending on the polarity of the battery, either a more vigorous reaction (though the same as the voltaic cell) would occur, or the reverse would.
