LiNO3; nitrate has a charge of -1, and lithium has a charge of +1

Answer: Option (a) is the correct answer.

Explanation:

A lithium atom has atomic number 3 and its electronic distribution is 2, 1. Therefore, it easily loses one electron and results in the formation of $Li^{+}$ which is known as lithium ion.

Whereas a nitrate ion has a chemical formula as $NO^{-}_{3}$ .

Since, charge on both lithium and nitrate ion is same in number. Therefore, when both these ions combine together then it results in the formation of $LiNO_{3}$ compound.

Name of this compound is lithium nitrate.

Thus, we can conclude that when a lithium ion and nitrate ion combine, the result is $LiNO_{3}$ .

If I add the same amounts of ice to water, cooking oil, and corn syrup then they will lose heat at the same/different rates beca

Vilka [71]

Ice is cold and water cools down heat, cooking oil isn’t hot unless you add it to heat, corn syrup isn’t hot unless you add it to heat as well so, they’d all lose heat at the same/different rates because they are all cooled beverages/subjects.

What does covalent and ionic bond have to do with chemical bond?

krok68 [10]

Covalent and ionic bonds are two different types of chemical bonding. Covalent bonds involve the sharing of electrons between 2 atoms while ionic bonds involve the complete transferring of electrons from one atom to another. Covalent bonds usually form between two nonmetals while ionic bonds usually form between a metal and a nonmetal.
I hope this helps. Let me know if anything is unclear.

Consider the above reaction. If some CO2 were removed from the container, what would the reaction do in an attempt to replace th

faltersainse [42]

Answer:

See explanation

Explanation:

The reaction to be considered is shown below;

H2CO3<------->CO2 + H2O

We know that when a constraint such as a sudden change in concentration, pressure or temperature is imposed on a reaction system in equilibrium, the system has to adjust itself by shifting in a particular direction in order to cancel the constraint.

Now, if we remove CO2, the equilibrium position must shift to the right by the decomposition of more H2CO3 to establish equilibrium again.

Magnesium sulfate heptahydrate is heated until all the water is driven off. The sample loses 11.80 grams upon heating. What was

iren [92.7K]

Hello!

The initial mass of Magnesium Sulfate Heptahydrate (MgSO₄·7H₂O) is 23,08 g

The chemical reaction for the dehydrating of Magnesium Sulfate Heptahydrate (MgSO₄·7H₂O) is the following:

MgSO₄·7H₂O(s) + Δ → MgSO₄(s) + 7H₂O(g)

We know that the sample loses 11,80 g upon heating. That mass is the mass of Water that is released as vapor. Knowing that piece of information, we can apply the following conversion factor to go from the mass of water to the moles of water and back to the mass of the original compound (mi).

$mi=11,80gH_2O* \frac{1 mol H_2O}{18gH_2O}* \frac{1molMgSO_4.7H_2O}{7molH_2O}* \frac{246,47 g MgSO_4.7H_2O}{1 mol MgSO_4.7H_2O} \\ \\ mi=23,08gMgSO_4.7H_2O$

Have a nice day!

C2F4 effuses through a barrier at a rate of 4.6x10-6 mol/hour, while an unknown gas effuses at a rate of 5.8x10-6 mol/hour. What

umka21 [38]

The molar mass of the unknown compound is calculated as follows

let the unknown gas be represented by letter Y

Rate of C2F4/ rate of Y = sqrt of molar mass of gas Y/ molar mass of C2F4

= (4.6 x10^-6/ 5.8 x10^-6) = sqrt of Y/ 100

remove the square root sign by squaring in both side

(4.6 x 10^-6 / 5.8 x10^-6)^2 = Y/100

= 0.629 =Y/100

multiply both side by 100

Y= 62.9 is the molar mass of unknown gas
