He answer is 4.9 the graph to the right really means nothing.
Answer:
Hydrogen and fluorine form only one bond while carbon forms four bonds to other atoms.
Explanation:
This question brings us to the idea of valency. Fluorine is univalent while carbon is tetravalent.
Univalent means that fluorine can only form one bond to hydrogen while carbon forms as much as four bonds because it is tetravalent.
Hence fluorine and hydrogen have only one peg while carbon has four.
Answer:
Changes in colour of litmus paper.
- Blue litmus turns red under acidic conditions.
- Red litmus turns blue under basic conditions.
Noe
PH values:-
K is acidic as pH is <7
Hence K will change the colour of blue litmus paper.
#B
Examples of substances
- K=Vinegar, Tomatoes.
- M=Milk of magnesia,Soap
Answer:
no no no who are these some look good but are black what is this
The J.J. Thomson's experiment on the negatively charged particles or electrons.
<h3>
Which atomic models does Thomson’s experimental evidence support?</h3>
J.J. Thomson's experiments with the cathode ray tube showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup." He also determined that the negatively charged particle were much lighter than the positively charged particle.
So we can conclude that: The J.J. Thomson's experiment on the negatively charged particles or electrons.
