Answer:  Ernest Z. The energy is 1.549×10-19J

Explanation:

The maximum wavelength for which photoelectric effect occurs in sodium is 400 nm.

Photoelectric effect has to do with the ejection of electrons from a clean metal surface when energy is supplied in the form of light. All wavelengths of light are not capable of achieving photoelectric effect.

There exists a maximum wavelength that the incident rays must posses in order for photoelectric effect to occur. The maximum wavelength for which photoelectric effect occurs in sodium is 400 nm.

The wavelength of red light is around 625 - 740 nm which is far longer than the wavelength of violet light which is around 380 - 425 nm. Hence, when sodium metal is subjected to violet light, it causes the photoelectric effect but red light does not affect the sodium metal.

The molarity of the resulting solution obtained by mixing 658 mL of 0.250 M HCl solution with 325 mL of 0.600 M HCl solution is 0.366 M

We'll begin by calculating the number of mole of HCl in each solution. This can be obtained as follow:

Volume = 658 mL = 658 / 1000 = 0.658 L

Molarity = 0.250 M

Mole = Molarity x Volume

Mole of HCl = 0.250 × 0.658

Volume = 325 mL = 325 / 1000 = 0.325 L

Molarity = 0.6 M

Mole = Molarity x Volume

Mole of HCl = 0.6 × 0.325

Mole of HCl in solution 1 = 0.1645 mole

Mole of HCl in solution 2 = 0.195 mole

Total mole = 0.1645 + 0.195

Volume of solution 1 = 0.658 L

Volume of solution 2 = 0.325 L

Total Volume = 0.658 + 0.325

Total mole = 0.3595 mole

Total Volume = 0.983 L

Molarity = mole / Volume

Molarity = 0.3595 / 0.983

Therefore, the molarity of the resulting solution is 0.366 M

Answer:

hemoglobin to become bicarbonate

Explanation:

When carbon dioxide enters the blood it combines with hemoglobin to form carbamino hemoglobin or carboxyhemoglobin but most of it becomes carbonate ions and diffuse into the blood plasma.

Hemoglobin is a blood protein giving red colour to the blood. It helps to transport oxygen everywhere. When oxygen fills in the air sack, it combines with oxygen and form oxyhemoglobin.

However, hemoglobin have more affinity towards carbon dioxide and and they combines to form carbaminohemoglobin which prevents the transportation of oxygen through blood.

The carbon dioxide will be converted into carbonic acid by combining with water. This acid then forms its carbonate ions and these ions helps to maintain the blood pH to be constant.The carbonate ions, CO₃²⁻can easily diffuse into blood plasma.

Answer:  ground state

Explanation:  The ground state, assuming you’re talking about an electron in an atom. As far as isolated leptons go, the electron is the lowest energy among the electron, muon, and tau particles. Muons and tau particles are unstable. A tau can decay into a muon or electron or other decays, while a muon can decay into an electron and associated neutrinos or gamma rays. Each has a corresponding neutrino, all of which have really, really tiny masses.     P.S not copy pasted

Ground state is the lowest possible energy level that an electron can occupy. When the electron gains energy, it may move to a higher energy level. This is called the exited state.

The ground state is the lowest possible energy level that an electron can occupy within an atom. In this state, an electron is in its most stable configuration, meaning it is closest to the nucleus and has the lowest energy level available to it.

When an electron gains energy from an external source, such as absorbing a photon of light or heat, it can move to a higher energy level. This state is known as the excited state. In the excited state, the electron is located farther from the nucleus and possesses more energy than it does in the ground state. The additional energy is stored by the electron as potential energy in its increased distance from the nucleus.

The excited state is temporary. Electrons in an excited state are not stable, and they tend to return to lower energy levels (closer to the nucleus) by releasing the excess energy in the form of photons of light. This phenomenon is the basis for various processes, including fluorescence and emission spectra.

The empirical formula of the compound (calcium bromide) is CaBr₂

From the question given above, the following data were obtained:

Ca = 4.02 g

Br = 15.95 g

Divide by their molar mass to obtain their mole

Ca = 4.02 / 40 = 0.1005 mole

Br = 15.95 / 80 = 0.199 mole

Divide by the smallest to obtain the mole ratio

Ca = 0.1005 / 0.1005 = 1

Br = 0.199 / 0.1005 = 2

Therefore, the empirical formula of calcium bromide is CaBr₂
