Titration is a quantitative analysis method for determining the concentration of a substance from a measured titrant. According to the equation, if the reactants are halved, the amount of H2O produced will be halved.

The molecular equations for sodium hydroxide, hydrochloric acid, sodium chloride, and water can be expressed as:

 HCl + NaOH ⇒ NaCl + [tex]H_{2}[/tex]O

In the given equations, the spectator ions and the ionic equation can be distinguished as follows:

H⁺ + Cl⁻ Na⁺ + OH⁻ ⇒ Na⁺ + Cl⁻ + 2H⁺ + O⁻²

The net ionic equation is:

 H⁺ + OH⁻ ⇒ [tex]H_{2}[/tex]O

From the above equation, we can see that the production of water molecules depends on the number of reactants. The reactants are,

H⁺ and OH⁻.

Therefore, when the number of reactants is halved, the resulting water molecules are halved.

An empirical formula is a type of chemical formula that shows the simplest ratio of elements present in a compound, rather than the total number of atoms.

What are Atoms?

Atoms are the smallest indivisible particles that make up all matter in the universe. They consist of a nucleus containing protons and neutrons, surrounded by a cloud of electrons. Atoms make up all elements, which are the building blocks for all other forms of matter.

Step 1: Calculate the atomic mass of carbon, hydrogen, oxygen, and nitrogen.

Carbon: 12.011 g/mol

Hydrogen: 1.008 g/mol

Oxygen: 15.999 g/mol

Nitrogen: 14.007 g/mol

Step 2: Convert the mass of each element to moles.

Carbon: 83.884 g / 12.011 g/mol = 6.983 mol

Hydrogen: 10.486 g / 1.008 g/mol = 10.381 mol

Oxygen: 18.640 g / 15.999 g/mol = 1.164 mol

Nitrogen: (200.00 g - (83.884 g + 10.486 g + 18.640 g)) / 14.007 g/mol = 6.871 mol

Step 3: Divide each mole value by the smallest mole value to obtain the simplest whole number ratio.

Carbon: 6.983 mol / 6.983 mol = 1

Hydrogen: 10.381 mol / 6.983 mol = 1.485

Oxygen: 1.164 mol / 6.983 mol = 0.167

Nitrogen: 6.871 mol / 6.983 mol = 0.985

The empirical formula of the compound is CHNO.

Answer: There are five significant figures in 865,010.

Explanation:

When a degree of accuracy is stated by each digit present in a mathematical figure then it is called a significant figure.

Rules for counting significant figures is as follows.

So, in the given figure 865010 has five significant figures and the trailing zero will not be counted.

Thus, we can conclude that there are five significant figures in 865,010.

When a 211-mL sample of a 0.285 M CaCl₂ solution is left on a hot plate overnight and the following morning, the solution is 1.25 M, the volume of water evaporated from the 0.285 M CaCl₂ solution is 48.108 ml.

Molarity (M) is defined as the ratio of the number of moles of solute present in a solution to the volume of the solution in litres.

given here,

Molarity of the original solution(M₁) = 0.285M

Volume of the original solution(V₁) = 211 ml

Molarity of  the solution in the morning (M₂) = 1.25 M

Volume of the solution in the morning (V₂) = ?

We will calculate the volume of the solution in the morning by using the formula:

M₁ × V₁ = M₂ × V₂

⇒0.285 M× 211 ml = 1.25 M × V₂

⇒V₂ = 0.285 M× 211 ml / 1.25 M

⇒V₂= 48.108ml

The volume of water evaporated from the 0.285M CaCl₂ solution is 48.108 ml.

Explanation:

14) We need to find the # of moles of NaOH in 3.5 L solution. Note: 1 M = 1 mol/Ll

(3.00 mol NaOH/1 L)(3.5 L) = 10.5 mol NaOH

Next we need find the volume of 19.4M NaOH solution that contains 10.5 mol NaOH:

(10.5 mol NaOH)×(1 L NaOH/19.4 mol NaOH)

= 0.541 L NaOH

This means that 0.541 L (541 mL) of 19.4M NaOH solution must be diluted to 3.5 L in order to get 3.00M NaOH solution.

15) 425 mL (0.425 L) of 0.105M HCl solution contains

(0.105 mol HCl/1 L)×(0.425 L) = 0.0446 mol HCl

so when enough water is added to 1L, the molarity becomes

0.0446 mol HCl/1 L = 0.0446M HCl

16) CaBr2 ---> Ca^+2 + 2Br^-1

For every Ca^+2 ion in the solution, you have 2 Br^-1 ions

If the concentration of CaBr2 is 6 mol/L (or 6M),.then the concentration of Br^-1 irons is

[Br^-1] = 2×[Ca^+2] = 2×(6 mol/L) = 12 mol Br^-1/L

17) The reason you won't need 1.0 L of water is that part of the volume of the solution is taken up by the NaOH so you will always need slightly less than 1 L.

Como se puede apreciar, los coeficientes estequiométricos son uno por lo tanto, la cantidad de NaClO que se genera será igual a la cantidad de moles que reaccionan de NaOH

Answer:

0.0272 moles

Explanation:

The number of moles of acid that were neutralized can be found by multiplying the volume of the base (in liters) by its concentration (in moles/liter) and then multiplying that value by the stoichiometric coefficient of the acid in the balanced chemical equation for the neutralization reaction.

To begin, we need to convert the volume of the base from milliliters to liters.

50.40 mL = 0.0504 L

Next, we can multiply the volume of the base (in liters) by its concentration (in moles/liter) to find the number of moles of base used in the titration.

0.0504 L * 0.542 M = 0.0272 moles

Since this is a neutralization reaction between a monoprotic acid and a strong base, the acid:base ratio is 1:1.

So the acid that has been neutralized is also 0.0272 moles.

Answer:

For the second to last problem the coefficients is  1, 5, 3, and 4 and the last problem all the coefficients are 1's

Explanation:

For the second to last problem you put 3 next to CO₂ so C is 3 on both sides. Then you put 4 next to H₂O because H will then be 8 on both sides. Lastly you put 5 next to O₂ which will make 10 on the reactant side. On the product side the 3 next to CO₂ will make O on the product side 6 and the 4 next to H₂O will make O on the product side 4. You will then add both together and it will make 10, which will make 10 on both sides. Hope this helps!

Answer:

Nonmetals tend to gain electrons while metals tend to lose electrons.

Explanation:

The statement that describes the reaction of nonmetals and metals is "Nonmetals tend to gain electrons while metals tend to lose electrons."

Metals (such as copper and aluminum) are good heat and thermal conductors, whereas nonmetals (such as phosphorus and sulphur) are considered to be insulators.

When a metal reacts with a nonmetal, the metal loses electrons while the nonmetal gains electrons. In order to achieve their nearest noble gas configuration, elements can gain or lose electrons. The formation of ions for the octet's completion aids in their stability. Metals lose electrons to complete their octet in a reaction between metals and nonmetals, while nonmetals acquire electrons to complete their octet.

When metal atoms produce ions, they lose electrons from their outer shell; the ions are positive because they contain more protons than electrons. The ions that are generated have complete outer shells. The ions have a full outer shell and have the electrical structure of a noble gas (group zero element).

Nonmetals are found further to the right on the periodic table and have high ionization energy and electron affinities, making them comparatively easy to absorb electrons and difficult to lose them. They also have a higher number of valence electrons, and are on the verge of completing an octet of eight electrons.

Hence the correct answer is nonmetals tend to gain electrons while metals tend to lose electrons.
