What elements are in NaC2HO4 and how many atoms are in each element​

Given parameters:

Mass of sucrose  = 5g

Density of sucrose  = 1.12g/mL

Percentage of sucrose per liter of cane juice  = 12%

Unknown:

Volume of cane juice required =?

We need to understand the relationship between volume and density. Density represents mass per unit volume.

Mathematically;

                Density  =

Now, calculate the volume of sucrose;

                  1.12g/mL =

       Volume  =    =  4.46mL   = 4.46 x 10⁻³L since 1000mL  = 1L

Since 12% of one liter of cane juice is sucrose,  

                    12% of  x  liter of cane juice  = 4.46 x 10⁻³L

                   Volume of cane juice  = 4.46 x 10⁻³ x   = 0.037L

Volume of cane juice needed is  0.037L

   

The rate equation for a first order reaction can be expressed as follows:

In this context, k represents the reaction's rate constant, t denotes the time the reaction takes, is the initial concentration, and is the concentration at time t.

The rate constant of the reaction is .

(a) If we start with an initial concentration of 100, when 90% of the substance is eliminated, the remaining quantity at time t will be 100-90=10. By substituting the values,

The time required to destroy 90% of the substance amounts to 23.03 days.

(b) If the initial concentration is set at 100, when 99% is destroyed, the present amount at time t will be 100-99=1. By substituting the input values,

This results in a duration of 46.06 days required to eradicate 99% of the chemical.

(c) Should the initial concentration be set at 100, with 99.9% of the chemical removed, the remaining quantity at time t will be 100-99.9=0.1. Substituting the values yields

Thus, the time needed to eliminate 99.9% of the chemical is calculated as 69.09 days.

The molecular formula is C2H6O2

Attached is the solution:

Initially, convert the mass into moles.

Then, divide each mole by the smallest amount to identify the number of atoms in the empirical formula.

Next, calculate the empirical formula mass.

Then, determine the molecular formula by dividing the molar mass by the empirical formula mass.

Finally, multiply the empirical formula by the obtained answer to arrive at the molecular formula of the compound.

The answer is option c. It consists of ionic bonds.Explanation: For instance, sodium chloride (NaCl) is an example where a group 1 element (an alkali metal) combines with a halogen. Elements from group 1 produce +1 charged cations. This ionic compound cannot possess the formula XZ₂. Ionic compounds are also known to dissolve in water and do not feature covalent bonds.
