Answer:

1.667L of a 0.30M BaCl₂ solution

Explanation:

<em>Of a 0.30M barium chloride, contains 500.0mmol of barium chloride.</em>

<em />

Molarity is an unit of concentration used in chemistry defined as the moles of solute present in 1 liter of solution.

In a 0.30M BaCl₂ solution there are 0.30 moles of BaCl₂ in 1 liter of solution.

Now, in your solution you have 500mmol of BaCl₂ = 0.500 moles of BaCl₂ (1000 mmol = 1 mol). Thus, 0.500 moles of BaCl₂ are present in:

0.500 moles * (1L / 0.30 moles) =

juin [17]

Answer:

The time decreases steadily

Explanation:

We know that the rate of chemical reaction is defined as how fast or slow a chemical reaction proceeds. Hence a chemical reaction is said to proceed at a faster rate if it takes a lesser time for the reaction to get to completion.

There are certain factors that affects the rate of reaction, prominent among them is the concentration of reactants. Concentration simply means the amount of substance in a system.

Taking a look at the table given in the question, we will realize that the volume of HCl remained constant, the volume of thiosulphate increased steadily while the volume of water decreased steadily. Remember that concentration increases when less water is added to the system. This implies that the reactant concentration increases steadily. Hence, according to the collision theory, particles collide more frequently and the rate of reaction increases.

As the rate of reaction increases, it now takes a lesser time for the reaction to get to completion (indicated by the disappearance of the cross). Hence as we move down the table, it takes lesser and lesser time for the cross to disappear. This means that the column for time will decrease steadily.

What is the enthalpy for the following reaction? overall: C + 1/2O2→CO
telo118 [61]

Answer:

ΔH°(f) = -110.5 Kj/mole (exothermic)

Explanation:

C + 1/2O₂ => CO

This is asking for the 'Standard Heat of Formation (ΔH°(f)* for carbon monoxide (CO). Values for many compounds can be found in the appendix of most college general chemistry text books. From Ebbing & Gammon, 11th edition, General Chemistry, Appendix C, page 8A.

*Standard Heat of Formation by definition is the heat gained or lost on formation of a substance (compound) from its basic elements in standard state.

The ΔH°(f) values as indicated are found in the appendix of most college chemistry texts. By choosing any compound, one can determine the standard heat of formation equation for the substance of interest. For example, consider Magnesium Carbonate; MgCO₃(s).The basic standard states of each element is found in the Appendix on Thermodynamic Properties for Substances at 25°C & 1 atm. having  ΔH°(f) values = 0.00 Kj/mole. All elements in standard state have a 0 Kj/mol. See appendix and note that under the ΔH°(f) symbol some substances have 0.00 Kj/mol values. The associated element will be in basic standard state,

Standard Heat of Formation Equation for formation of Magnesium Carbonate;

Mg°(s) + C°(gpt)* + 3/2O₂(g) => MgCO₃(s) ; ΔH°(f) = -1111.7 Kj/mole

* gpt => graphite

Name the three functional groups in the compound pictured.
oksian1 [2.3K]

The three functional groups shown in the image are: ester, alkoxy and carboxyl.

<h3>What are functional groups?</h3>

Chemical properties depend on its structure. Certain properties, too, are attributable to an atomic group ordered in a particular way, apart from the whole of the molecule. Such groups of atoms that determine the chemical properties of compounds are called<em> functional groups</em>.

The functional group can be on the primary, secondary, or tertiary carbon.

Functional groups are often found on molecules of biological importance.

Functional groups are usually formed by a set of elements such as carbon, hydrogen and oxygen, attached to the hydrocarbon chain, giving the molecule characteristics. Can also include other elements such as sulfur or nitrogen.

Molecules can have more than one functional group on it, having different combinations on it that can affect properties of the molecule such as solubility, structure, or reactivity.

Carboxyl groups are usually seen in amino acids, fatty acids and other molecules since it is a fairly common functional group.

Therefore, we can confirm that the three functional groups shown in the image are: ester, alkoxy and carboxyl.
