The earth has enough gravity to do that
Answer:
Use a scientific calculator
The answer is dilute. A dilute salt solution contains a small amount of salt with high water concentration while a concentrated salt solution has a large amount of salt with a lower water concentration. Salt is inorganic hence it is not monounsaturated, which is a term related to organic compounds. The salt is unable to dissolve anymore in a saturated salt solution, leaving the undissolved salt at the bottom and this is not the case here since we only have a small amount of salt.
Answer:
2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2
Explanation:
The balanced reaction equation is shown below;
2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2
This reaction is possible because the reduction potential of Rb is -2.98V while that of Ba is –2.92 V. Hence Rb can displace Ba from its salt solution.
The equation is balanced since the number of atoms of each element on the left and right hand sides of the reaction equation are equal.
