Calculation of Percent Composition

Chemistry
1 answer:
Trava [24]3 years ago
6 0

Answer:

C: 61.0%, H: 15.3%, N: 23.7%

Explanation:

We can calculate the percent by mass of each element using the following expression.

%Element = (mass of the element/mass of the compound) × 100%

Carbon

%C = (7.34 g/12.04 g) × 100% = 61.0%

Hydrogen

%H = (1.85 g/12.04 g) × 100% = 15.3%

Nitrogen

%N = (2.85 g/12.04 g) × 100% = 23.7%

The percent composition of this compound is C: 61.0%, H: 15.3%, N: 23.7%.

Answer:

The products are SnPO4 and LiC2H3O2

Explanation:

The reactants are LiPO4 + Sn(C2H3O2)2

This is a double replacement reaction

So what you do is switch the elements the other way around.

To do that, all you have to do switch Sn with PO4 since Sn is a cation and PO4 is an anion.

Then you switch Li with C2H3O2 because Li is a cation and C2H3O2 is an anion.

After that, check the charges. PO4 has -3 charge

So just leave Sn the way it is without a subscript.

In word form, the product would be Tin(III) Phosphate

C2H3O2 has a -1 charge Li has a +1 charge

So leave both of them the way it is without any subscripts.

In word form, the product would be Lithium Acetate

cupoosta [38]

Answer:

Following are the responses to the given question:

Explanation:

In the given question the OH could be generated as the H-bond with both the N (nitrogen), which is used to place its N as the partially positive value(+). It is used to simplifies the addition for either its  AA with the imine C. In the above H-bond, the w N is not required as the possibility to use the OCH3

the use of logic making empirical observations and preforming dissections were all part of the scientific studies by
olga55 [171]

The answer is: Aristotle.

Aristotle (384–322 BC) was an ancient Greek philosopher.

He was interested in empirical studies and shifted from Platonism to empiricism.

Empiricism is a theory that states that knowledge comes from sensory experience and through experiments.

Empirical evidence is the information received by observation through experimentation.

Write the scientific term.
Reil [10]

Answer:  Solubility.

Explanation:

Solubility is defined as the maximum amount of solute dissolved per 100 g of the solvent at a certain fixed temperature to form a saturated solution.

STP condition is Standard Temperature and Pressure condition which is  temperature of 273 K and pressure of 1 atm.

Thus the scientific term for "the number of grams of solute dissolved in 100 g of the solvent to form a saturated solution at STP​" is called as Solubility.
