Answer and Explanation:

The freezing point of Titanium is 1668 C or 3034.4 F...

The freezing point of Titanium (Ti) is 1668°C.

Titanium is a chemical element. The symbol of titanium is Ti. Atomic number of Ti is 22. Electronic configuration of Titanium is [Ar] 3d² 4s².

The temperature of a liquid which changes its state and becomes a solid is called as Freezing point. The freezing point of Titanium is 1668°C.

Thus from the above conclusion we can say that The freezing point of Titanium (Ti) is 1668°C.

Answer:

The amount of fluid displaced is directly related (via Archimedes' principle) to its volume. In the case of an object that sinks (is totally submerged), the volume of the object is displaced. In the case of an object that floats, the amount of fluid displaced will be equal in weight to the displacing object.

Answer:

Temperature measures the average kinetic energy of the particles in a substance. Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance's temperature and thermal energy.

Explanation:

A substance’s total thermal energy depends on its temperature, the number of atoms, and physical state. More atoms and higher temperature mean more thermal energy. If all other conditions are the same, substances in gas form have the most thermal energy, followed by liquids, then solids.

Temperature can be measured with a thermometer. The matter inside a thermometer expands as its particles gain thermal energy and move.

The kinetic energy of a body is associated with its motion and is dependant on its speed and mass. Similarly, thermal energy associated with a body increases its temperature more when it is moving.

Kinetic energy is a form of energy generated by virtue of its motion. Kinetic energy is related with the mass m and speed v of the moving body by the expression below:

KE = 1/2 mv².

Thus, kinetic energy increases with an increase in mass and velocity of the body. When the particles are under motion with raised temperature,  the molecules inside body overcome the energy barrier to move and aquire more kinetic energy.

Thus an in increase in thermal energy results in an increase in temperature of the body as well increase in kinetic energy. The overall change in both kinetic and thermal energy depends on the mass, speed of motion and temperature of the system.

Answer: They either eat other organisms or plants they take in the sun and water.

Answer:

See answer below

Explanation:

As you are asking for chemical formula and ionic equation, then, I will assume that after the station #3 below, are the solutions you are requiring.

You are also not specifing if you want for example, result of solution 1 + solution 3. If you need that, please post that on another question.

Now for the chemical formula, you need to identify the elements in all 3 solutions, and also the type of compound.

1. Solution 2 Potassium Iodide:

In this case we have Potassium on one side, and Iodine on the other side, the symbol for those are K and l. As Potassium have the +1 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Iodide it will be -1, so, the formula will be:

KI

And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:  

K⁺ + I⁻ ------> KI

2. Solution 1 and 3, Lead (II) nitrate and Sodium carbonate:

In this case I will work with both, because both of the solution are tertiary compounds. In this cases, we have two tertiary salt, The Sodium symbol is Na, and is working with it oxydation state +1. Carbonate is an anion and have the formula CO₃ working with the oxydation state -2. Lead can work with oxidation state +2 and +4. It's symbol is Pb. Nitrate is NO₃ and works with oxydation state -1 instead.

The chemical formula and ionic equation for both will be:

Lead(II) nitrate: Pb(NO₃)₂

Sodium Carbonate: Na₂CO₃

And the net equations:

Lead nitrate: Pb²⁺ + 2NO₃⁻ ------> Pb(NO₃)₂

Copper sulfate: 2Na⁺ + CO₃²⁻ -------> Na₂CO₃

Knowing that the cell cycle has two phases

A cell at the end of interphase would have grown in volume and have a doubled amount of DNA compared to the same cell at the end of m phase. Such a cell would also have more biochemical contents than its counterpart at the end of m phase.

The interphase is divided into;

A cell at the end of m phase undergoes massive growth and development at the G1 phase, doubles its DNA at the S phase through replication, and synthesizes proteins at the G2 phase before hopping into the m phase again.

Answer: ATP is the energy currency molecule which is required for cellular processes.

Explanation:

When the cell require metabolic energy to perform a particular a task. From the ATP or adenosine triphosphate molecule one of three phosphate molecule gets displaced and liberates the resulting molecule becomes adenosine diphosphate or ADP. The phosphate molecule is used by the cell to perform different cellular and metabolic functions as a source of metabolic energy. The phosphate is released by the hydrolysis of the phosphoanhydride bond with the other phosphate group.

Answer:

So, the elements with similar properties to sodium (Na) are all of those elements in the same Group.

Explanation:

The ones "most" similar would be the ones closest in mass as well. Those would be Lithium (Li) and Potassium (K).

Answer:A) N and P

Explanation:

N and P, because they are in the same group on the periodic table. This is because they both have 3 valence electrons, and properties of elements are dependent partly on the number of valence electrons they have.

The reactants in this expression above is limestone

The products of the reaction is carbon dioxide and lime

Reactant is the species that gives the product and it is usually found on the left hand side of the expression.

The product is the substance on the right hand side of the expression that forms through the experiment.

Heat is used to facilitate the reaction.

5. An exothermic reaction is a reaction in which heat is given off.

An endothermic reaction is a reaction in which heat is absorbed in the process.

An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.
