In a particle accelerator, the accelerated particle primarily gains kinetic energy. A particle accelerator is a device that accelerates particles which means it would add more energy to the particles increasing the kinetic energy of these particles. This is commonly used in medical and any scientific research.

Calculate the volume of a 2.30 mol/L solution of Na2CO3 that contains 0.325 mol of solute.
Blababa [14]

Answer:

141 mL is the volume of a 2.30 mol/L solution of Na₂CO₃ that contains 0.325 mol of solute.

Explanation:

Molarity is a measure of concentration of a solution that indicates the amount of moles of solute that appear dissolved in each liter of the mixture.

So 2.30 mol / L indicates that 2.30 moles dissolve in 1 L of solution. You want to know in what volume is contained 0.325 mol of solute. For this you apply the following rule of three: if 2.30 moles of solute are present in 1 L of solution, 0.325 moles in how much volume is it?

volume=\frac{0.325 moles*1L}{2.30 moles}

volume= 0.141 L

Being 1L=1000 mL, then 0.141 L=141 mL

<u><em>141 mL is the volume of a 2.30 mol/L solution of Na₂CO₃ that contains 0.325 mol of solute.</em></u>

Use the periodic table to determine which of the following could be an isotope of indium (In). Check all that apply. Z = 49, A =
Anastasy [175]

The isotopes are the elements with same atomic number but different atomic mass or mass number

The mass number is denoted by Z

The mass number is denoted by A

The number of neutrons = N

We know that for an element

A = Z + N

As given the element is indium , its atomic number = Z = 49

Z = 49, A = 113 N = 64,  This could be an isotope of indium

Z = 49 N = 61, A = 113 , this could also be an isotope of indium

A = 110, N = 49 it means Z = Z - N = 110-49 = 61 So this is not isotope of indium

In the lab you react 2.0 g of Na2CO3 with enough CaCl2. According to the reaction Na2CO3 + CaCl2 -&gt; CaCO3 + 2NaCl How much Ca
vlada-n [284]

Answer:

1.89 g CaCO₃

Explanation:

You will have to use stoichiometry for this question.  First, look at the chemical equation.

Na₂CO₃  +  CaCl₂  ==>  2 NaCl  +  CaCO₃

From the above equation, you can see that for one mole of Na₂CO₃, you will produce one mole of CaCO₃.  This means that however many moles of Na₂CO₃ you have in the beginning, you will have the same amount of moles  of CaCO₃, theoretically speaking.

So, convert grams to moles.  You should get 0.0189 mol Na₂CO₃.  This means that you will get 0.0189 mol CaCO₃.  I'm not sure what units you want the answer in, but I'm going to give it in grams.  Convert moles to grams.  Your answer should be 1.89 g.
