Answer:

Explanation:

a) The forward reaction is exothermic, hence when temperature is increased the equilibrium shift towards the reactants side to get rid of the excess energy. This will mean that more reactants are produced decreasing yield

b) There are a fewer number of moles of gas on the right side compared to the left side (Just count the coefficients before each compound) so a higher pressure will mean that the equilibrium will shift towards the products side in order to decrease the pressure. This will mean that more products are formed increasing yield

c) When something is powdered it's surface area to volume ratio increases. A higher surface area means that the particles around it have more area to work on so the frequency of collisions will increase increasing the rate of reaction. This is why iron is powdered.

What is the symbol of an ion with 16 protons, 18 neutrons, and 18 electrons? what is the symbol for an ion that has 16 pro-tons,
Goshia [24]

When we go to periodic table, Sulfur is an element that has 16 protons and 16 electrons.

when there is 18 electrons, with number of two electrons more than protons. This makes it an ion and the ion has a -2 charge.

So when there is16 protons, 18 neutrons, and 18 electrons the symbol is S⁻².

The neutrons have no charge but they add only mass to the elements. So when there is 16 neutrons, it doesn't change the symbol of ion.

Which of the following correctly summarizes the
Grace [21]

Answer:

A

Explanation:

The lithosphere represents the layer of hardened/solid rock that makes up the hard part of the earth, including the brittle upper portion of the mantle and the crust. The lithosphere is broken into pieces that are referred to as plates. The pieces move to and away from each other in a process known as plate tectonics. The movement of plates accounts for the global locations of volcanoes, earthquakes, and mountain ranges.

<em>The lithosphere is made of largely of inorganic materials known as silicates. The weathering of the solid rocks together with the interaction of living organisms gives rise to soil with an appreciable amount of organic materials.</em>

The correct option is, therefore A.
