_____NaOH + _____H2 SO4 _____ Na2SO4 + _____ H2O ,
To balance this equation,
Step 1:
Balance the number of sodium on both side:
by multiplying the NaOH by 2 that is:
2NaOH+H2SO4-------->Na2SO4+H2O
Step2:
As NOW the number of oxygen atom and hydrogen atom are not equal on both sides. So we multiply this H2O by 2 that is:
2NaOH+H2SO4-------->Na2SO4+2H2O
Now the no of all atoms on product side is equal to no of all atoms in the reactant side.
so the coefficient is 2 NaOH+1 H2SO4-------->1 Na2SO4+2 H2O.
The iterative process is the practice of building, refining, and improving a project, product, or initiative. Teams that use the iterative development process create, test, and revise until they're satisfied with the end result.
The iterative process is a technique research and development teams use to help them optimize their products, services and business processes. The process involves repeated trial-and-error style cycles, where researchers adjust each cycle according to what they learned in the previous iteration.
By using this method, teams can design planned changes for their processes and encourage steady improvements toward an end goal. Careful planning and consideration of feedback can help teams conduct successful iterative processes.
Typically, business development and marketing research professionals use the iterative process to help them address design concerns, improve business strategies, optimize product features or quickly adjust to market changes.
The method can used for a variety of businesses and applications. Teams in marketing, software development, engineering, education or design might all use this process to analyze products or processes within their business.

Answer:
Mostly Metals, But hydrogen is the only one that isn't.
<u>Answer:</u> The percent composition of
in taconite is 37.6 %.
<u>Explanation:</u>
We are given:
Mass of taconite pellets = 1 ton = 907185 g (Conversion factor: 1 ton = 907185 g)
Mass of iron produced = 545 lb = 247212 g (Conversion factor: 1 lb = 453.6 g )
We know that:
Molar mass of iron = 55.85 g/mol
Molar mass of
= 231.53 g/mol
1 mole of
contains 3 moles of iron atom and 4 moles of oxygen atom
(3 × 55.85) = 167.55 g of iron is produced from 231.53 grams of ![Fe_3O_4](https://tex.z-dn.net/?f=Fe_3O_4)
So, 247212 grams of iron will be produced from =
of ![Fe_3O_4](https://tex.z-dn.net/?f=Fe_3O_4)
To calculate the percentage of
in taconite, we use the equation:
![\%\text{ composition of }Fe_3O_4=\frac{\text{Mass of }Fe_3O_4}{\text{Mass of taconite}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20composition%20of%20%7DFe_3O_4%3D%5Cfrac%7B%5Ctext%7BMass%20of%20%7DFe_3O_4%7D%7B%5Ctext%7BMass%20of%20taconite%7D%7D%5Ctimes%20100)
Mass of taconite = 907185 g
Mass of
= 341611.43 g
Putting values in above equation, we get:
![\%\text{ composition of }Fe_3O_4=\frac{341611.43g}{907185g}\times 100=37.6\%](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20composition%20of%20%7DFe_3O_4%3D%5Cfrac%7B341611.43g%7D%7B907185g%7D%5Ctimes%20100%3D37.6%5C%25)
Hence, the percent composition of
in taconite is 37.6 %.
