Balance the equation: ___HgO → ___O2 + ___Hg

Chemistry
2 answers:
wel3 years ago
7 0

Answer: 2HgO\rightarrow O_2+2Hg

Explanation:

According to the law of conservation of mass, 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. Thus chemical equations are balanced.

The balanced chemical equation for the reaction is:

2HgO\rightarrow O_2+2Hg

Thus if the product is O_2 , there are 2 atoms of oxygen. When a coefficient 2 is placed in front of the reactant HgO, there will be 2 atoms of oxygen and 2 atoms of mercury. Thus a coeeficient of 2 is to be added to product side in front of Hg.

2HgO -> 1 O2 + 2Hg

remember first there's 2 oxygens so then you check the other side and make it 2 too. then you see that now there's 2Hg and then you put a 2 on the other side to make it 2Hg too. balancing is just making sure the number of elements on one side equal the other.

Which of the following would be classified as an acid to the Arrhenius definition
mixer [17]

Any substance that increases the concentration of H^+ in aqueous solutions is Arrhenius's acid.

<h3>What are Arrhenius acids?</h3>

Arrhenius define acids as substances with the chemical capacities to increase the concentration of hydrogen ion in aqueous solutions.

Thus, substances like HCl, HNO3, HBr, etc. would be considered an acid. This is because they ionize in aqueous solutions as follows:

HCl ---> H^+ + Cl^-

HNO_3 --- > H^+ + NO_3^-

HBr --- > H^+ + Br^-

which of these species is most likely to be a lewis acid and is also least likely to be a bronsted acid
pochemuha

Answer:

This question is incomplete but the completed question is below

Which Of These Species Is Most Likely To Be A Lewis Acid And Is Also Least Likely To Be A Brønsted Acid? (A) NH4⁺ (B) BF₃ (C) H₂O (D) OH⁻

The correct option is B

Explanation:

A lewis acid is a substance that accepts (or is capable of accepting) a pair of electrons. For example BF₃, while a lewis base is a substance that donates (or is capable of donating) a pair of electrons. For example OH⁻.

If we take a look at the boron (B) in BF₃, it has 3 electrons on it's outermost shell, each of which are bonded to flourine and can still accept a pair of electrons (lone pair). <u>This makes it very likely to be a lewis acid</u>.

Bronsted lowry acid is a substance that donates or can donate a proton or H⁺ (for example HCl) while bronsted lowry base is a substance that accepts or can accept a proton or H⁺ (for example NH₃).

<u>BF₃ cannot donate a proton or H⁺ hence it is least likely to be called a bronsted acid.</u>

Lewis Diagrams- Grade 10 Chemistry<br><br> Please can someone explain this to me?
natita [175]
Lewis diagram:
well first you have to know the Valence electrons the elements which will on top of the periodic table.

for examples:
H2O
it will be O-H-O and the dots will on top. oxygen have 6 valence electrons so that mean it need 6 dots. also for H it will have 7 V-electrons.
