B is the answer I think hope this helps
Answer:
Ocean currents!!
Explanation:
The Oceans of the earth transfer heat from one location to another via massive ocean currents. These currents are like river flowing across the vastness of Earth, bringing warm water from the equator up towards higher latitudes, and cooler water down towards the equator.
Answer:
[NaOH} = 0.4 M
Explanation:
In a reaction of neutralization, we determine the equivalence point of the titration. In this case, we have a strong base and a strong acid.
(H₂SO₄, is considered strong, but the first deprotonation is weak)
2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
As we have 2 protons in the acid, we need 2 OH⁻ from the base to form 2 molecules of water.
In the equivalence point we know mmoles of base = mmoles of acid
Let's finish the excersise with the formula
25 mL . M NaOH = 28.2 mL . 0.355M
M NaOH = (28.2 mL . 0.355M) / 25 mL → 0.400
<span>Colligative properties are properties of solutions that depend on the number of molecules [or ions] in a given volume of solvent and not on the properties (e.g. size or mass) of the compound. Colligative properties include: lowering of vapor pressure; elevation of boiling point; depression of freezing point and osmotic pressure.</span>
Energy levels are the electron shells where electrons are found at a fixed distance from the nucleus of the atom. The atom could emit 6 different wavelengths.
<h3>What is wavelength?</h3>
A wavelength is a distance between the adjacent crests in wave signals propagated in a system. Wavelength is in inverse relation to the frequency of the wave.
When an electron jumps from energy level 1 to 2, 1 to 3, and 1 to 4 one wavelength each is present. Hence, making the total wavelength to be 3, in transition from the first energy level.
Similarly, from energy levels, 2 to 3 and 2 to 4, a total of 2 wavelengths, and from energy levels 3 to 4 one wavelength is produced.
So the total different wavelengths of the radiation that can be emitted will be 3 + 2 + 1 = 6.
Therefore, 6 different wavelengths of radiation will be emitted by the atom.
