Which liquid has a maximum vapor pressure?

List three characteristics of chemical reactions and three characteristics of nuclear reactions.

zubka84 [21]

Answer:

Explanation:

Chemical Reactions

1. The rate of a chemical reaction is affected by some factors such as: pressure, temperature, surface area e.t.c

2. Chemical reactions do not involve in changes with regard to the nuclei but in the reorganization of electrons.

3. Isotopes of an element in a chemical reaction behave in a similar manner.

Nuclear Reactions.

1. Nuclear reactions involves a change with respect to the nucleus of an atom, resulting in the production of a different element.

2. The rates of a nuclear reaction are not affected by external factors such as : temperature, pressure, catalyst e. t. c, but are usually spontaneous.

3. Large amount of energy usually accompany nuclear reactions.

Nuclear fission is the splitting of atomic nuclei, while nuclear fusion is the combining of atomic nuclei.

Simora [160]

Nuclear reactions are those that involve the nucleus of an atom. Nuclear fission involves the splitting of an atomic nucleus and the formation of two distinct atomic species. Nuclear fusion is indeed the combining of two atomic nuclei in order to form a single atomic species. Therefore the answer to the question is true.

An unknown compound is discovered in a raid on a terrorist organization; it is believed that the compound is Sarin. When a 10.0-

Eduardwww [97]

Given:

Mass of the unknown compound (believed to be Sarin) = 10.0 g

Mass of CO2 produced = 15.6 g

Mass of H2O produced = 6.4 g

To determine:

If the unknown compound is Sarin

Explanation:

The molecular formula for Sarin is: C₄H₁₀FO₂P

Based on stoichiometry the C:H ratio = 4:10 i.e 2:5

Now, from the combustion data:

# moles of CO2 produced = # moles of C present in the unknown sample

Similarly, (# moles of H2O produced)*2 = # moles of H present in the unknown sample

# moles of CO2 = 15.6 g/44 g.mol-1 = 0.354 moles

# moles of H2O = (6.4 g/ 18 g.mol-1 )* 2 = 0.711 moles

The C:H ratio = 0.354 : 0.711 = 1:2

Ans: Since the C:H ratio does not match the actual stoichiometry based on the molecular formula, the unknown compound is not Sarin.
