The correct answer is A. Density

Explanation:

In chemistry, a physical property differs from a chemical property because physical properties can be observed or determined without changing the substance. Example of this includes color, density or texture while examples of chemical properties include toxicity, flammability, reactivity, oxidation, etc. Density (mass per unit) is classified as part of physical properties because this can be determined by dividing the mass of the substance by its volume which means this property can be measured without altering the substance and therefore it is a physical property.

Consider the reaction
Aleks [24]

Answer:

A), C), and E)

Explanation:

We need to use the Le Chatelier´s principle to answer this question as follows:

A)  Increasing the size of the reaction vessel has the effect of decreasing pressure, so the equilibrium will shif to the side that has greater pressure which in this case is the products, so we the number of moles of CS2 will increase.

B) If we add more product Cl2 to the system it will shift to the reactants  to counteract the change in the equilibrium; therefore, some CS2 will be consumed.

C) If we add reactant S2Cl2 to the system it will shift to the product side therby increasing the number of moles of CS2

D) The reaction is endothermic so it will shift to the reactant side.

E) Adding more reactant CCl4  will shift the equilibrium to the right side favoring more CS2

A fat is composed, in part, of long chains of carbon and hydrogen. This fat as a molecular
IgorLugansk [536]

Answer:

C_{54}H_{102}O_6

Explanation:

Hello!

In this case, since the molar mass of the empirical formula is:

MM_{empircal}=9*12.01+17*1.01+16.00=141.26g/mol

Thus, the ratio of the molecular to the empirical formula is:

\frac{847g/mol}{141.26g/mol} =6.0

Thus, the molecular formula is six times the empirical formula:

C_{54}H_{102}O_6

Best regards!
