Answer:
No this statement is false.
Explanation:
when an atom lose or gain the electron ions are formed. If the atom lose an electron the positive ions are formed called cations while anion is formed by the gaining of electron by an atom The elements having less electrons in valance shell usually lose their electrons while the elements like halogens having 7 valance electrons gain an electron to complete the octet. while p block elements noble gases are inert, their outer most valance shell is complete so they do not form ions.
P block elements are non-metals, metals and metalloids. These are thirty five elements. The P-block elements are present on right side of periodic table. There valance electrons are present in P orbital. The p-block metals are shiny and good conductor of heat and electricity. These metal lose the electron which is accept by non metals and form ionic bond. They have high melting points.
Metalloids includes boron, silicon, germanium, arsenic, antimony and tellurium. Metalloids contain both the properties of metals and non metals, Some metalloids are toxic like arsenic.
Most of p-block elements are non metals. They are bad conductor of heat and electricity and have low boiling points. The non metals mostly accept the electron from the metals and usually from ionic bond like in case of chlorine. It form the ionic compound with sodium.
The sodium chloride which is an ionic compound, formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.
Answer:
its hydroxy and alkoxy
Explanation:
ester is mainly formed by substitution reaction of carboxylic acid and alcohol
Answer: c. Matter and energy are conserved in chemical reactions.
Explanation:
According to the law of conservation of matter, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
For every chemical reaction, the law of conservation of energy is applicable which states that the energy of the system remains conserved. Energy can neither be created nor destroyed. It can be transformed from one form to another.
I think the answer is D not too sure tho
The empirical formula is C₂H₃O₂
<h3>What is Empirical formula of a compound ?</h3>
The empirical formula is the simplest whole number ratio of elements present in a compound.
The total molar mass of the compound is 118.084 g/mol.
mass of Carbon present = 40.6
mass of Hydrogen present = 5.1 grams
mass of Oxygen present = 2 grams
Moles of C = 40.6/12 = 3.38
Moles of H = 5.1/1.008 = 5
Moles of Oxygen = 54.2/15.999 = 3.38
Ratio of Moles of C to Oxygen is 1 : 1
Ratio of Moles of C to H is 1/1.5
Multiplying each mole fraction by 2
The empirical formula is C₂H₃O₂
