Answer:HN3 is a weak acid as its conjugate base anion formed after deprotonation is very unstable.
Kindly refer the attachments for the resonating structures of HN3 and N3- anion.
Explanation:
Kindly refer the attachment for structure of azide ion.
The azide ion is a explosive due to the highly unstable structure of azide ion and a strong tendency for the formation of nitrogen molecule which is stable.
So azides decompose very quickly to give nitrogen molecule which is very stable on account of triple bond.
The azide ion basically has 3 resonating forms .There are 3 Nitrogen atoms and the central nitrogen atom is positively charged as it forms double bonds with each of the two nitogens.
Although there is some delocalization of charges present on the three nitrogen atoms but the fact is that in the structure there are charges present of different polarity .So one of the nitrogen is positively charged and other two nitrogens are negatively charged. Due to this separation of charges of different polarity this unstability arises. It is nitrogen only which has to carry the postive as well as negative charge.
The resonance structure of HN₃ is also similar as in this structure also there is charge separation between positive and negative charges but here due to the presence of hydrogen one of the negative charge is neutralised and molecule is sightly neutralized as no nitrogen atom has to bear 2 negative charge as in the case of azide ion.
Kindly refer the attachments:
Answer : The figure is attached in the attachment.
Explanation : The central atom will be carbon to which at 109.8 degrees will be each chlorine atoms. And the central carbon atom is
hybridized. There will be four chlorine atom surrounding the central carbon atom. There will be 3 lone pairs of electron on each of the chlorine atom which gets attached with carbon atom.
Answer: See the answer in image.
Explanation:
Answer:
The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).
Explanation:
According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, <em>matter can be neither created nor destroyed</em>. It can only be transformed.
Therefore, in a <u>chemical reaction the atoms are conserved</u>. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and <u>the amount and type of atoms of the products will be the same as the reactants</u>.
In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.
The question is incomplete, the complete question is;
the element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. its melting point is 1910 degrees celsius.” which correctly evaluates the statement? not reliable because opinions are presented, reliable because testable facts are presented, not reliable because it is very brief ,reliable because metric units are used
Answer:
reliable because testable facts are presented
Explanation:
Science is a body of knowledge that deals with testable facts. Science is highly empirical and any superstitious proposition is quickly discarded as nonsense.
The statement, ''The element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. Its melting point is 1910 degrees Celsius" presents facts that can be verified by laboratory investigation.
Hence we can conclude that the given statement is reliable because it contains testable facts.
