Answer:

The correct answer is - C.  Increasing the concentration increases the reaction rate.

Explanation:

In the given question the data with change in different factors affect the rate of reaction differently as it alters the time it takes to complete reaction:

Conditions                            Reaction Time

Original                                  10 seconds

Higher concentration            5 seconds

Higher temperature              5 seconds  

Metal added                           5 seconds

As it is given above, time is decreased in each condition including in the case of increasing the concentration of the reactants which means the rate of reaction increases as well.

Rank the states of matter from the LEAST amount of energy to MOST
nataly862011 [7]

Answer:

The ranking of matter from the LEAST amount of energy to MOST amount of energy is;

B. Solid, Liquid, Gas

Explanation:

The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating

Solid state (Least amount of energy)

In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer

Liquid state (Intermediate amount of energy)

As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state

Upon further heating the particles in the liquid acquire more energy and are  and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form

Gaseous state (Most amount of energy)

From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed

Therefore, the correct option is Solid, Liquid, Gas.

Write the balanced NET ionic equation for the reaction when chromium(III) bromide and sodium phosphate are mixed in aqueous solu
Mariulka [41]

The balanced NET ionic equation for the reaction is CrBr₃(aq) + Na₃PO₄(aq) ==> CrPO₄(s) + 3NaBr(aq)

<h3>What is a balanced Ionic equation ?</h3>

In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.

Additionally, the net charge is the same on both sides of the equation.

Separate into the complete ionic equation.

It should be obvious that the aquous solutions ionize and the solid is shows as the molecule since it doesn't dissolve.

Cr³⁺(aq) + 3Br⁻(aq) + 3K⁺(aq) + PO₄³⁻(aq) ==> CrPO₄(s) + 3K⁺(aq) + 3Br⁻(aq)

Now look and cancel those ions common to both sides. What is left is the net ionic equation.

Cr³⁺(aq) + PO₄³⁻aq) ==> CrPO₄(s)
