4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer

weqwewe [10]

Hello!

This question requires a model -- you'll have to do that yourself. However, I can explain the steps for the process:

• Chlorophyll absorbs the sun's energy.

• The energy is used to split water molecules into hydrogen and oxygen.

• The oxygen is released from the leaves into the atmosphere.

• The hydrogen and carbon dioxide glucose (food) for plants.

Crystal structures with ions must have ____________.a. a positive chargeb. a negative chargec. electrical neutralityd. a 2+ char

Inessa05 [86]

Answer:

c. electrical neutrality.

Explanation:

A <em>crystalline solid</em><em> possesses a rigid and long-range order; its atoms, molecules, or ions occupy specific positions.</em> The arrangement of such particles in a crystalline solid is such that the net attractive intermolecular forces are at their maximum.

Ionic crystals, particularly, have two important characteristics:

(1) They are composed of charged species.

(2) Anions and cations are generally quite different in size.

The forces holding the atoms together are electrostatic attractions. Examples of these types of crystals include NaCl, LiF, MgO, CaCO₃.

<u>Since they are composed of anions and cations, in stoichiometric amount, they are to be said electrically neutral.</u>

A compound is found to contain 63.65 % nitrogen and 36.35 % oxygen by mass. what is the empirical formula for this compound?

kodGreya [7K]

Let the total mass of the compound is 100 g.

Mass of N = 63.65 % = 63.65 g

Mass of O = 36.35 % = 36.35 g

Molar mass of N = 14.01 g/mol

Molar mass of O = 16.00 g/mol

Number of moles (mol) = mass (g) / molar mass(g/mol)

Number of Moles of N = 63.65 g / 14.01 g/mol = 4.54 mol

Number of Moles of O = 36.35 g / 16.00 g/mol = 2.27 mol

Divide the Number of moles of each element with the lowest number of moles, here lowest number of moles is 2.27 .

Dividing number of the moles of each element by lowest number of moles to get the mole ratio between elements.

N = 4.54 mol / 2.27 mol = 2

O = 2.27 mol / 2.27 mol = 1

So, Empirical formula = N₂O₁ = N₂O

Distinguish between the terms "insoluble" and "unsaturated." Give an example to illustrate each term.

Serjik [45]

Insoluble means that a substance does not dissociate in another, like mixing water and oil.

In an unsaturated solution, the solute does dissociate into solution but there is more "room" in the solution to hold more. Say if you have an amount of water that can dissolve 20g of salt but you only have 15g dissolved in it, that solution is unsaturated.
