a 47.2-ml sample of naoh is titrated with 0.624 m hbr. 27.4 ml of the acid are required to reach the equivalence point. what is the molarity of the base?

Answers

Answer 1

The molarity of the base would be 0.36 M.

What is Molarity?

The number of moles of dissolved solute per litre of solution is the definition of molarity, a unit of concentration. Molarity is defined as the number of millimoles per millilitre of solution by dividing the number of moles and the volume by 1000. A precise 1.000 mole of KCl (74.55 g) must be dissolved in a quantity of water or another solvent to produce a precise 1.000 litre of solution in order to create a 1.000 M solution of KCl.

In actuality, this concentration unit is frequently abused. Since KCl is totally dissociated, the solution, for instance, with water as the solvent, is exactly 1.000 M in K+ and 1.000 M in Cl.

Recall that: mole = molarity x volume

Also; molarity = mole/volume

Mole of 0.624 M, 27.4 mL HBr = 0.624 x 27.4/1000

                                                 = 0.017 mol

If the mole of HBr is 0.017 mol, the equivalent mole of NaOH will also be 0.017 mol.

0.017 mol of 47.2 mL (0.0472 L) NaOH would molarity of:

0.017/0.0472 = 0.36 M

In other words, the molarity of the NaOH is 0.36 M.

what volume (ml) of 7.48 × 10-2 m phosphoric acid can be neutralized with 115 ml of 0.244 m sodium hydroxide?

Answers

Volume of the original phosphoric acid solution is 375.133 ml.

What is phosphoric acid?
Phosphoric acid
, also known as orthophosphoric acid, monophosphoric acid, or phosphoric(V) acid, is an inorganic solid with the chemical formula H3PO4 that contains phosphorus. It is frequently found as an 85% aqueous solution, that is a syrupy liquid that is colourless, odourless, and non-volatile. It is a significant industrial chemical that is used in numerous fertilisers. This substance is an acid. The phosphate ion PO 3 4 is produced when all three H+ ions are removed. Dihydrogen phosphate ion H2PO 4 and hydrogen phosphate ion HPO24 are produced, respectively, by removing one or two protons. Organophosphates are esters created by phosphoric acid.

Here, we have given two solution with their conc. and volume .
So, formula used to calculate volume is:
M1V1 = M2V2

let, M1 = molarity of phosphoric acid
V1 = volume of phosphoric acid used
M2 = molarity of NaOH
V2 = volume of NaOH used

Now,
7.48 X 10-2  X  V1 = 0.244 x 115
V1 = 0.244 x 115/ 7.48 X 10-2
V1 = 375.133 ml.

How many individual decay steps are in the decay chain of uranium-238 before the stable end product of lead-206 is produced?

Answers

When stable lead-206 is produced by the radioactive decay of uranium-238, it passes through a 14-step radioactive decay series. There are eight and six decays in this sequence.

What is radioactive decay ?

Ionizing radiation is released as a result of radioactive decay. Ionizing radiation offers a health concern by destroying tissue and the DNA in genes because it can damage the atoms in living things.

The decay chain is the collection of decay products produced to achieve this equilibrium. For instance, after producing intermediates like Uranium-234, Thorium-230, Radium-226, and Radon-222, the decay chain starting with Uranium-238 ends in Lead-206. Known as the "decay series" as well.

The daughter nucleus, thorium 234, is created by the alpha emission of a uranium 238 nuclei. This thorium then changes into protactinium 234 and experiences beta-negative decay to yield uranium 234 as a byproduct.

what mass of cacl2 is required to make 53 ml of a 0.020 m cacl2 solution? g cacl2 how many moles of chloride ions are present in the solution?

Answers

1.176 g of CaCl2 is required to make 53 mL of a 0.020 M CaCl2 solution, and there are 0.0106 moles of chloride ions present in the solution.

What is chloride ion?
The anion (negative charges ion) called Cl is the chloride ion. It is created when a compound like hydrogen chloride dissolves in water or even other polar solvents, or when the halogen element chlorine gains an electron. Sodium chloride and other chloride salts are frequently very water soluble. It is a crucial electrolyte that is present in all bodily fluids and is in charge of maintaining the proper acid-base balance, transmitting nerve signals, and controlling the flow of fluid into and out of cells. Less frequently, this same word chloride could also be included in chemical compounds' "common" names. These compounds contain one or even more chlorine atoms bound together covalently.

To calculate the mass of CaCl2 required to make 53 mL of a 0.020 M CaCl2 solution, we need to use the equation:
Mass (g) = Volume (mL) x Molarity (M) x Molar Mass (g/mol)
Mass (g) = 53 mL x 0.020 M x 110.98 g/mol
Mass (g) = 1.176 g CaCl2

To calculate the number of moles of chloride ions in the solution, we need to use the equation:
Moles = Mass (g) x (1mol/Molar Mass (g/mol))
Moles = 1.176 g x (1mol/110.98 g/mol)
Moles = 0.0106 moles Cl- ions

Therefore, 1.176 g of CaCl2 is required to make 53 mL of a 0.020 M CaCl2 solution, and there are 0.0106 moles of chloride ions present in the solution.

The voltage that exists between a battery's two half cells can be measured using the cell potential. We will describe how to do this and what elements make it possible for us to determine the voltage that is present inside an electrochemical cell. The potential difference between the two half cells inside an electrochemical cell is measured by the cell potential, or Ecell. The ability of electron density to move from one half cell to another is what determines the potential difference. Due to the fact that the chemical reaction is just a redox reaction, electrons can move between the electrodes.

The half reactions for the Zn/Zn2+//Cu2+/Cu cell are:
Oxidation: Zn → Zn2+ + 2e-
Reduction: Cu2+ + 2e- → Cu

The overall reaction is:
Zn + Cu2+ → Zn2+ + Cu

The cell potential can be calculated from the standard reduction potentials of the two half reactions:

when gas molecules collide (for example molecules of o2 or n2 in the air), why don't they stick together?

Answers

when gas molecules collide (for example molecules of o2 or n2 in the air),  they don't  stick together due to their high thermal energy.

Why are collisions between gas molecules said to be elastic?

Because gas molecules are so small, the kinetic theory of gases assumes that every collision between them will be fully elastic. The energy and momenta of the molecules are conserved during collisions if the molecules are small. As a result, regardless of accidents, the temperature does not change.

What is an elastic collision between gas particles according to the kinetic theory?

Any collision in which there is no overall kinetic energy loss is said to be elastic. During an elastic collision, kinetic energy may be transmitted from one particle to another, but the combined energy of the colliding particles remains unchanged.

describe what happens during the citric acid cycle and identify where the carbon atoms of acetyl coa end up and where the energy that was stored in acetyl coa ends up.

Answers

Through a series of enzymatic reactions, the two carbons that were formerly the acetyl group of acetyl CoA are released as carbon dioxide, one of the primary byproducts of cellular respiration, in the citric acid cycle.

All six carbon atoms from the original glucose molecule are eventually incorporated into carbon dioxide because the two acetyl carbon atoms will eventually be released on later turns of the cycle.

write the balanced reaction for the combustion of hexanol, ch3ch2ch2ch2ch2ch2oh? (be sure to use whole number coefficients.)

Answers

The balanced reaction for the combustion of hexanol is:

2C₆H₁₄(g)+19O₂(g)→12CO₂(g)+14H₂O(g) 2 C ₆ H 14 ( g ) + 19O₂ ( g ) → 12CO₂ ( g ) + 14 H₂O ( g )

What is balanced reaction?

An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same total charge and the same number of atoms for each component of the reaction. In other words, the reaction has equal amounts of mass and charge on both sides.

For instance, think about the response: O2 (g) + 2Mg(s) = 2MgO (g) Two magnesium and two oxygen atoms are present on the reactant and product sides of this reaction. The chemical reaction is a balanced chemical equation because it follows the law of conservation of mass.

a firm runs its technology operations on a fleet of amazon ec2 instances. the firm needs a certain software to be available on the instances to support their daily workflows. the developer team has been told to use the user data feature of ec2 instances.

Answers

User Data is generally used to perform common automated configuration tasks and even run scripts after the instance starts. When you launch an instance in Amazon EC2, you can pass two types of user data - shell scripts and cloud-init directives. You can also pass this data into the launch wizard as plain text or as a file.

In general, a configuration is the arrangement of the components that make up a whole, or the act of creating that arrangement. A configuration, or particular shape, is produced when objects are placed in any spatial arrangement. As an illustration, scientists refer to a configuration as the particular, bound arrangement of atoms that forms a molecule.

Text, observations, figures, photos, numbers, graphs, and symbols can all be used as forms of data. Individual prices, weights, addresses, ages, names, temperatures, dates, or distances, for instance, could be included in the data. Data is an unprocessed type of knowledge and has no meaning or use by itself.
