Answer:

the last thing to bee observed is the damage

Explanation:

A volcanic event occurs when there is a sudden or continuing release of ... (1) an eruptive pulse (essentially an explosion with an eruption plume, but also ... events like caldera collapse, or long erosional intervals, and may last 10 m.y. or more ... where a certain type of behavior was first observed or most commonly occurs.

What determines the velocity of an object? Its acceleration at a given point in time Its weight in a given location Its displace

tensa zangetsu [6.8K]

We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

<h3>How do we know that displacement and time determine velocity?</h3>

We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is $\frac{d}{t}$ , meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.

Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

The amount of I−3(aq) in a solution can be determined by titration with a solution containing a known concentration of S2O2−3(aq

Pavlova-9 [17]

Answer : The molarity of $I_3^-$ in the solution is, 0.128 M

Explanation :

The given balanced chemical reaction is,

$2S_2O_2^{-3}(aq)+I_3(aq)\rightarrow S_4O_2^{-6}(aq)+3I^-(aq)$

First we have to calculate the moles of $Na_2S_2O_3$ .

$\text{Moles of }Na_2S_2O_3=\text{Molarity of }Na_2S_2O_3\times \text{Volume of solution}$

$\text{Moles of }Na_2S_2O_3=0.260mole/L\times 0.0296L=0.007696mole$

Conversion used : (1 L = 1000 ml)

Now we have to calculate the moles of $I_3^-$ .

From the balanced chemical reaction, we conclude that

As, 2 moles of $S_2O_2^{-3}$ react with 1 mole of $I_3^-$

So, 0.007696 moles of $S_2O_2^{-3}$ react with $\frac{0.007696}{2}=0.003848$ mole of $I_3^-$

The moles of $I_3^-$ = 0.003848 mole

Now we have to calculate the molarity of $I_3^-$ .

$\text{Molarity of }I_3^-=\frac{\text{Moles of }I_3^-}{\text{Volume of solution}}$

Now put all the given values in this formula, we get:

$\text{Molarity of }I_3^-=\frac{0.003848mole}{0.03L}=0.128mole/L=0.128M$

Therefore, the molarity of $I_3^-$ in the solution is, 0.128 M

The small part of the nucleus where ribosomal subunit formation takes place

vaieri [72.5K]

The small part of the nucleus where ribosomal subunit formation takes place is called the nucleolus. This structure is found in eukaryotic cells and takes up about 25 percent of the volume of the nucleus. This structure is said to be the brain of the nucleus. It is made up of ribobucleic acids or the RNA and proteins. Its primary function is to transcript the ribosomal RNA (rRNA) and to combine these with the proteins resulting to the formation of an incomplete ribosome. Since it is closely related to a chromosomal matter of a cell and important in the production of ribosome, this structure is correlated to be one of the cause of a number of diseases.
