Answer:The correct answer is option b.

Explanation:

Acid a are those compound which gives hydronium ions in their aqueous solution.

$HA+H_2O\rightarrow A^-+H_3O^+$

$H_2SO_4+H_2O\rightarrow SO_{4}^{2-}+2H^+$

Sulfuric acid in its aqueous solution gives sulfate ions and hydronium ions.

Hence, the correct answer is option b.

A certain compound is made up of one carbon (c) atom, two bromine (br) atoms, and one oxygen (o) atom. what is the chemical form

padilas [110]

Answer:
Chemical Formula = COBr₂

Structural Formula = Attached Below

IUPAC Name = Carbonic Dibromide

Common Name = Bromophosgene

As we know Carbon has the tendency to form four covalent bonds, Oxygen can form two covalent bonds and Bromine can form a single bond. Keeping this in mind we can say that in given compound carbon is forming two single bonds with two bromine atoms and a double bond with oxygen atom. Therefore, the valencies of all elements in the given compound are satisfied and completed.

f 23.2 grams of an aqueous solution of nickel(II) iodide, NiI2, contains 5.47 grams of nickel(II) iodide, what is the percentage

Dahasolnce [82]

Answer:

the percentage by mass of Nickel(II) iodide = 23.58%

Explanation:

% by mass of solute = (mass of solute/mass of solution) x 100%

% by mass of NiI2 = (mass of NiI2/mass of solution) x 100%

% by mass of NiI2 = (5.47 grams/23.2 grams) x 100% = 23.58% m/m

Answer:

A FUSE is a type of conductor which protects the circuit by shorting it down when there is excess flow of current passing through it.

Explanation:

A fuse wire is made up of conducting materials such as alloy of tin and lead that has high resistivity. It has a low melting point of 200°C. It works based on the principle of heating effect of electric current. The functions of fuses include the following:

--> Fuses are made up of thin wire CONDUCTORS which interrupts or breaks the current flow of a circuit when in excess, thereby protecting the circuit from damage.

--> it prevents overload of current. In the event where too many appliances are connected to a single circuit, this can lead to overload which triggers a fuse to terminate the circuit connection.

--> It prevents total black-out: SWITCH-LIKE devices known as CIRCUIT BREAKERS share this function with the fuses. The nearest circuit breaks if any dysfunction occurs in the components of the circuit thereby preventing blackout.
