Most problems are not so simple. To solve more general carbon-dating problems, you must first find the value of the decay consta

nt for 14C, so that you can easily use the decay equation.
Using the given half-life, 5730 years, find the value of the decay constant for 14C.

Answer:

Half-life = 1.21x10⁻⁴ years⁻¹

Explanation:

The kinetics decay of ¹⁴C follows the first order reaction. That means half-life of ¹⁴C is defined as:

Half-life = ln 2 / K

<em>Where K is decay constant.</em>

<em />

As decay constant of ¹⁴C is 5730 years, half-life is:

Half-life = ln 2 / 5730 years

<em>Half-life = 1.21x10⁻⁴ years⁻¹</em>

<em />

Tried solving this multiple ways, but keep getting the wrong answer. So, I would appreciate the help. Thank you.​

Answer:

I can give you the definition ... That might help cause I honestly don't kno the answer either ;-;

Explanation:

When used as a diacritic mark, the term dot is usually reserved for the interpunct, or to the glyphs 'combining dot above' and 'combining dot below' which may be combined with some letters of the extended Latin alphabets in use in Central European languages and Vietnamese.

Here is an example:

The dot product between a unit vector and itself is also simple to compute. In this case, the angle is zero and cosθ=1. Given that the vectors are all of length one, the dot products are i⋅i=j⋅j=k⋅k=1.

Complete the following single replacement reaction. If they don’t react, just write “NR”
stiv31 [10]

We have to complete all the given reactions.

1. Fe(s) + CuCl₂ → Cu + FeCl₂

2. Cu(s) + FeCl₂(aq)  → NR (no reaction takes place)

3. K(s) + NiBr2(aq) → NR (no reaction takes place)

4. Ni(s) + KBr(aq) → K + NiBr₂

5. Zn(s) + Ca(NO₃)₂(aq) → NR (no reaction)

6. Ca(s) + Zn(NO₃)₂(aq) → Zn(s) + Ca(NO₃)₂(aq)

How would adding the catalyst nitrogen monoxide (NO) affect this reaction?
marin [14]

<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

A catalyst is defined as the substance which increases the rate of the reaction without actually participating in the reaction.

This substance decreases the activation energy of the reactants, so as to proceed the reaction at a faster rate by increasing their effective collisions.

It does not affect the concentration of the reactants.

For the given reaction:

2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)

If we add NO, which is acting as a catalyst will increase the rate of the reaction to produce the products which is SO_3

Hence, the correct answer is Option A.
