Be sure to answer all parts. Acetone is one of the most important solvents in organic chemistry. It is used to dissolve everythi

ng from fats and waxes to airplane glue and nail polish. At high temperatures, it decomposes in a first-order process to methane and ethene (CH2═C═O). At 600°C, the rate constant is 8.7 × 10−3 s−1. (a) What is the half-life of the reaction

Answer:

Half life = 79.67 sec

Explanation:

Given that:

k = 8.7\times 10^{-3}\ s^{-1}

The expression for half life is shown below as:-

t_{1/2}=\frac{\ln2}{k}

Where, k is rate constant

So,  

t_{1/2}=\frac{\ln2}{8.7\times 10^{-3}\ s^{-1}}

t_{1/2}=114.94252\ln \left(2\right)\ sec=79.67\ sec

Half life = 79.67 sec

Forces that change an object motion by touching the object are _______ forces
strojnjashka [21]

Forces are pushes and pulls that may change the motion of an object. Balanced forces result in an object remaining at rest or moving at a constant speed. Unbalanced forces result in the acceleration of an object. An object's motion depends on how it changes position.

Explain the importance of carbon's ability to form covalent bonds in straight chains, branched chains, or rings.
viktelen [127]
Carbon is the element at the heart of all organic compounds, and it is such a versatile element because of its ability to form straight chains, branched chains, and rings. Because these chains and rings can have all sorts of different functional groups in all sorts of different ways (giving the compond all sorts of different physical and chemical properties), carbon's ability to form the backbone of these large structures is critial to the existence of most chemical compounds known to man. Above all, the organic molecules crucial to the biochemical systems that govern living organisms depend on carbon compounds.

Create the Lewis structure of CF4. NOTE: do only the step asked for in each part and then click Check–don't work ahead to solve
Naya [18.7K]

To create the Lewis structure we need to take into account the octet rule: atoms tend to gain, lose or share electrons to complete their valence shell with 8 electrons.

C belongs to Group 4A in the periodic table so it has 4 valence electrons. It needs to share 4 pairs of electrons to complete the octet.

F belongs to Group 7A in the periodic table so it has 7 valence electrons. Each F needs to share 1 pair of electrons to complete the octet.

As a consequence, in CF₄, C will form a single bond with each F and all the octets will be complete.
