It doesn't become SnO4. It becomes SnO2 because Sn2O4 can be simplified into that. 2:2=1 (the subscript of Sn) and 4:2=2 (the subscript of O)
The oxidation number for Sn in SnO4^2- is +4. Oxygen is typically assigned an oxidation number of -2, so the sum of the oxidation numbers in the compound equals the overall charge of -2 for the ion.
Bromine tends to gain one electron to become a Br- ion.
Liquids become solids upon freezing. Most solids contract when they freeze. The expansion of water when it becomes ice is an unusual property.
An atom can become positively charged by losing an electron, resulting in more protons than electrons. Conversely, an atom can become negatively charged by gaining an electron, which creates an excess of electrons compared to protons.
Oxygen gains 2 electrons to become an oxide ion (O2-).
The oxidation number for Sn in SnO4^2- is +4. Oxygen is typically assigned an oxidation number of -2, so the sum of the oxidation numbers in the compound equals the overall charge of -2 for the ion.
tin (IV) oxide it is actually Sn2O4 in simplified form.
The Answer To Your Question Is.... tin (IV) oxide
The balanced chemical equation for tin(II) chloride reacting with water is SnCl2 + 2H2O -> Sn(OH)2 + 2HCl.
Calcium oxide (CaO) is often considered one of the strongest basic oxides. It forms a strong base when it reacts with water, producing hydroxide ions. This makes it highly alkaline and capable of neutralizing acids effectively.
It is SnO2Why? Because:Tin has a charge of 4 and Oxygen has a charge of 2. Their charges are switched to make a compound; therefore, the chemical formula would be written as Sn2O4. Then, you have to simplify that so it would be written as SnO2.
will become, shall become, (am/are/is) going to become,
The past participle of become is also have or has become. She has become a better person.
The past participle of "become" is also "become" as in "I have become a better person."
The future perfect tense of become is will have become.
(I, We, You, They) become. (He, She, It) becomes.
Has become. The 3rd person singular (he, she, it) uses 'has become.' The other persons of the conjugation use 'have become.' He has become class president. She has become homecoming princess. It has become time to go. 'Become' is the correct participial form of the verb; is become, has become, had become, might have become, will become, etc. 'Became' is the simple past tense conjugation of the verb, and is never used as the participle.
