Isotopes of elements have different:

Chemistry
1 answer:
Ray Of Light [21]3 years ago
7 0
<span>Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different number of neutrons. They differ in the number of neutrons that is why they also differ in mass numbers. Since they have the same number of protons, they have the same atomic number. 
For instance, when the nucleus of the isotope with a 68.926 amu, there are 30 protons and 39 neutrons in the nucleus. The best example for this is Zn (zinc-69 isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu respectively.

A certain metal M forms a soluble sulfate salt M2SO4. Suppose the left half cell of a galvanic cell apparatus is filled with a 5
VikaD [51]

Answer:

Right

Explanation:

The given parameters are;

The soluble sulfate formed by the metal, M = M₂SO₄

In the galvanic cell formed by the metal M, we have;

The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M

The concentration of M₂SO₄ in the right half cell = 5.00 M

In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated

In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode

Therefore;

The electrode which will be positive is the electrode in the right half cell.

  • 1) <em>Because the crystals do not have much time to develop if the lava cools fast, they are quite tiny. If the lava cools gradually, the crystals will have ample time to form and become huge. The size of crystals in an igneous rock is a good predictor of the conditions under which the rock developed. </em>
  • <em>2) Intrusive igneous rocks cool slowly from magma in the crust. They have a lot of crystals. Extrusive igneous rocks cool fast from lava near the surface. They are covered with tiny crystals.</em>
  • <em>3) Usually they will contain metal elements that oxidise easily. For example, the Igneous rocks on them Moon (the Maria or 'oceans') are darker in colour due to a higher percentage of iron.</em>
  • <em>4) The hue of igneous rocks is proportional to their density. Darker colored rocks have a higher density because they contain more material and iron. Light colored rocks have a lesser density because they contain less material and iron.</em>
  • <em>5)  Magma is hot, molten rock under the earth's surface; lava is when magma reaches the earth's surface (it is then called lava).</em>
  • <em>6) The mineral grains with a pegmatitic texture are unusually big. The biggest ones are often more than 3 cm long. In intrusive rocks, this texture can be seen. The fact that they were particularly big did not imply that they cooled slowly.</em>
  • <em>7)  Igneous rocks are classified according to their origin, texture and mineral composition. A igneous rock formed from lava that erupted on to earths surface.</em>

An oceanographer went into the ocean to measure the salinity at different areas. Where would you expect the oceanographer to fin
grigory [225]

Due to high evaporation rate and low precipitation, the oceanographer to find the highest salinity at the tropics.

<h3>What is salinity?</h3>

Salinity refers to the salt content of a water body such as rivers and oceans.

Oceans and seas have high salinity due to the presence of many dissolved minerals.

Different area of the oceans have different salinities.

Salinity is highest at the tropics and equator due to high rate of evaporation and low precipitation.

Therefore, the oceanographer to find the highest salinityat the tropics.
