It takes 5.54 mL of a 2.18 M NaOH solution to neutralize 6.19 mL of an HCl solution. What is the concentration of the HCl solution? Do not include units in your
answer. Round to the tenths place or further.

Answers

Answer:

2 M

Explanation:

NaOH + HCl --> NaCl + H2O,

5.54 mL = .00545 L,

If we consider 2.18 M, M [molarity] = mol/L, so we have 2.18 mol/L. From this we can get the moles of NaOH.

.00545 L *  2.18 mol/L ≈ .0121 mol

The concentration of HCl can be found from the following:

.0121 mol = .00619(x) [where x = concentration of HCl]

x = 1.955 M ≈ 2 M

We equate the two as we require the same amount in order to neutralize the base.

How many grams of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide

Answers

Answer:

2 grams.

Explanation:

H2 + O2 --->  H2O2

What is the pH of a solution with a (H+] = 0.80 M? *Please round your answer to the appropriate number of significant figures. Your answer can be in standard notatic "e" in place of x10.*​

Answers

Answer:

The pH of a solution with a (H+] = 0.80 M is [tex]9.6 e^{-2}[/tex]

Explanation:

As we know

pH = -[log H+]

Substituting the value of H+ ion concentration in the above equation, we get -

pH = -log [0.80]

pH [tex]= -[-0.096] = 0.096 = 9.6 e^{-2}[/tex]

Solid potassium chloride is obtained by the reaction of solid potassium and chlorine gas.
Write a balanced chemical equation for this reaction.

Answers

Answer:

2 K(s) + Cl₂ (g) --> 2 KCl(s)

Explanation:

Potassium will just be K

Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂

Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl

Balancing the amounts of each will lead to 2 K(s) + Cl₂ (g) --> 2 KCl(s)

why is atomic radi measured using the nuclues from 2 of the same atoms

Answers

Explanation:

Atomic radii is measured using the distance between nucleus of 2 atoms rather than the distance between the nucleus and outermost shell because:

- There is no clear/sharp boundary of the orbital. This is why it is called an electron cloud.

- Also, the exact location of the electron is not known. What is known is the probability of finding the electron there.

Due to this, it is not possible to measure the atomic radii precisely. That's why the distance between the nucleus of two atoms is used.

Between the chemical reaction of the chemicals and the label on the bottle the ions from in the radioactive product contained in the bottle separates the label from the surface. Im guessing that due to the "radioactive waste" in the bottle that there are components of thermal heat, that may also have an effect on the "label".  So when talking about the reaction we have a chemical and thermal reaction happening.

What is the ideal gas equation?

The ideal gas equation can be defined as an equation that describes the behavior of an ideal gas. This equation gives by the product of the volume and pressure is equal to the product of the moles of gas, gas constant, and absolute temperature.

The mathematical form of the ideal gas law is given as follows:

PV = nRT

Where n is the moles, V is the volume, R is the universal gas constant and P is the pressure.

The temperature of the N₂ , T =  0° C = 273 K

The pressure of the gas at STP, P = 1 atm

The value of the universal gas constant, R = 0.082 atm L/K mol

The number of moles of N₂, n = 0.881 mol

Fill in the values n, R, P, and T in the equation, and we get:

1 × V = 0.881 × 0.082 × 273

V = 19.72 L
