What do scientist typically do with the result of their research

zalisa [80]

When scientists conduct an experiment and analyze the results, the next step is to write up a report that describes the experiment and the results and submit it for publication in a scientific or medical journal that is “peer reviewed.”

Explain what occurs in a substance reaction

Rama09 [41]

In a chemical reaction, the atoms of the starting species called reactants rearrange to form new substances which are the products of the chemical reaction. The identities of the atoms involved in the reaction remain the same. Their number also stays the same before and after the reaction

How many moles of calcium chloride are theoretically produced for the following reaction given we have 2.6 moles of HCl and 1.4

Georgia [21]

Answer : The number of moles of calcium chloride theoretically produced are, 1.3 moles.

Explanation : Given,

Moles of HCl = 2.6 moles

Moles of $Ca(OH)_2$ = 1.4 moles

Now we have to calculate the limiting and excess reagent.

The given balanced chemical reaction is:

$2HCl+Ca(OH)_2\rightarrow 2H_2O+CaCl_2$

From the balanced reaction we conclude that

As, 2 mole of $HCl$ react with 1 mole of $Ca(OH)_2$

So, 2.6 moles of $HCl$ react with $\frac{2.6}{2}=1.3$ moles of $Ca(OH)_2$

From this we conclude that, $Ca(OH)_2$ is an excess reagent because the given moles are greater than the required moles and $HCl$ is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of $CaCl_2$

From the reaction, we conclude that

As, 2 mole of $HCl$ react to give 1 mole of $CaCl_2$

So, 2.6 moles of $HCl$ react to give $\frac{2.6}{2}=1.3$ moles of $CaCl_2$

Therefore, the number of moles of calcium chloride theoretically produced are, 1.3 moles.

What phase of matter has enough kinetic energy to partially overcome the intermolecular attraction between the particles, allowi

MatroZZZ [7]

Answer:

Liquid

Explanation:

It is liquid because liquid will always take shape of the container. For example, take a square container and a round cup, and a 1/d of water, put it in the square container and it will take the shape of that container, but take the SAME water and put it in the cup and now its in a circle cause it is taking shape.
