Which formulas represent one iconic compound and one molecular compound

1 answer:

6 0

An ionic compound is any compound containing a metal and a nonmetal

For example: NaCl, MgO, etc

Sometimes they’ll include polyatomic ions, such as CN (cyanide), ClO3 (chlorate), and many others

For example: NaCN, LiClO3, etc

A covalent or molecular compound usually contains shared pairs of electrons

Some examples are H2O, CO2, CHCl3

Notice, that these are all composed of non-metals.

Hope this helps. It’s hard to answer specifically when I can’t see the options.

If this helps, give me a brainliest, so I know I was helpful.

During the combustion of 2.00 g of coal, the temperature of 500 g of water inside the calorimeter increased from 25.0°c to 43.7°

pantera1 [17]

Answer is: 39,083kJ.
m(coal) = 2,00g.
m(water) = 500g.
ΔT = 43,7°C - 25°C = 18,7°C, difference at temperatures.
c(water) = 4,18 J/g·°C, specific heat of water
Q = m(water)·ΔT·c(water), heat of reaction.
Q = 500g·18,7°C·4,18J/g·°C.
Q = 39083J = 39,083kJ.

Antacids work to relieve stomach acids because of which of the following types of reactions?

Anastaziya [24]

Answer: The correct answer is Option B.

Explanation:

Decomposition is a type of chemical reaction in which larger compound breaks down into two or more smaller compounds.

$AB\rightarrow A+B$

Double displacement reactions is defined as the chemical reaction in which exchange of ions takes place.

$AB+CD\rightarrow AD+CB$

Synthesis reaction is a type of reaction in which two or more smaller compounds combines to form a single large compound.

$A+B\rightarrow AB$

Single displacement reaction is a type of reaction in which a more reactive metal displaces a less reactive metal from its chemical reaction.

$A+BC\rightarrow AC+B$

In stomach, an acid is present known as hydrochloric acid and to neutralize its effect, antacid is taken which has $CaCO_$ as a component.

The reaction between HCl and $CaCO_3$ is a type of neutralization reaction and it is a type of double displacement reaction.

The equation between the two follows:

$CaCO_3+HCl\rightarrow CaCl_2+H_2O+CO_2$

Hence, the correct answer is Option B.
