New elements are synthesized from the nuclear reaction of already existing elements. The change in nuclear composition of an atom leads to the conversion to new element.
What are elements ?
Elements are the basic things of anything in the world. Elements join together to form molecule and compounds. There are 118 known elements in periodic table.
Many more elements discovered by scientists are accidental. The properties of each elements are determined based on their atomic number. The nuclear reactions mostly for radioactive elements make new elements with different nuclear composition.
New elements are produced as sub products that are resulted from several synthesis reactions involving the nuclear change. Radioactivity involving bombardment of charged particles such as alpha, beta or their emission also leads to formation of new elements.

Explanation:
Molar mass of potassium nitrate will be calculated as follows.
Molar mass = molar mass of K + molar mass of N + 3 × molar mass of O
= 39.098 g/mol + 14.006 g/mol + 3 × 15.999 g/mol
= 102.102 g/mol
Now, adding the given amount of potassium nitrate present in each beaker as follows.
(2.3 + 1.91 + 5.985 + 0.52) g
= 10.715 g
Therefore, calculate number of moles as follows.
No. of moles =
=
= 0.105 mol
Thus, we can conclude that 0.105 moles of potassium nitrate were recovered after the water evaporated.
Answer with double replacement
Answers
Answer:
Barium chloride + Sodium phosphate → barium phosphate + sodium chloride
Explanation:
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Chemical equation:
BaCl₂ + Na₃PO₄ → Ba₃(PO₄)₂ + NaCl
Balanced chemical equation:
3BaCl₂ + 2Na₃PO₄ → Ba₃(PO₄)₂ + 6NaCl
The cation and anion of both reactants are exchanged with each other.
Ba²⁺ react with PO₄³⁻ and form Ba₃(PO₄)₂ while Cl⁻ react with Na⁺ and form sodium chloride.
Molecular equation:
Barium chloride + Sodium phosphate → barium phosphate + sodium chloride
Final answer:
A double replacement reaction between barium chloride and sodium phosphate results in the formation of barium phosphate and sodium chloride.
Explanation:
The given chemical equation represents a double replacement reaction. The chemical reactants are barium chloride (BaCl2) and sodium phosphate (Na3PO4). In a double replacement reaction, the cations and anions of the two reactants switch places to form two new compounds.
So here is how the reaction would proceed: BaCl2 + Na3PO4 -> Ba3(PO4)2 + NaCl.
This translates to: Barium chloride reacts with sodium phosphate to form barium phosphate and sodium chloride.

Answer: The final temperature of the sample is 62.66°C
Explanation:
To calculate the amount of heat absorbed, we use the equation:
where,
Q = heat absorbed = 16.7 kJ = 16700 J (Conversion factor: 1 kJ = 1000 J)
m = Mass of the sample = 225 g
c = specific heat capacity of sample =
= change in temperature =
Putting values in above equation, we get:
Hence, the final temperature of the sample is 62.66°C

When a student is warming a chemical in a container using a special burner, it is very important to focus on safety by using the right safety tools.
What is the safety equipment
First, the student needs to wear the right safety clothes like a lab coat, gloves, and goggles to protect themselves from getting splashed or hurt by chemicals. A lab coat stops chemicals from touching the skin, gloves keep the hands safe, and safety goggles protect the eyes from chemicals
and hot things.
Furthermore, using a fume hood is necessary to make sure there is enough fresh air circulating and to remove any dangerous fumes or gases that might be released while heating things up.

Answer:The student should be wearing a lab coat or maybe an apron to prevent chemicals from spilling or exploding onto their clothes, I do recommend a lab coat better though because it can protect your skin better. Next, make sure while messing with chemicals you are always wearing goggles, if you are not wearing them there is a chance that after touching chemicals you could touch your eyes. And that brings me to washing your hands straight away after messing with chemicals. You could also wear gloves and just take them off when you're done but if you don't have clean hands afterward you could always put the chemicals all over your skin. But in case you do touch your eyes there is always an emergency eyewash station somewhere in the lab room. And if you are to get Chemicals on your skin, in your hair, on your clothes, or to be on fire, there shall be a shower somewhere to get rid of that. But if you read the instructions or listen closely to the teacher you shall have no problem.

Calculating the original amount of U-238
- The number of moles present in each element is first determined:
- Number of moles = mass/molar mass
For Pb-206:
mass = 0.37 mg = 0.37 * 10⁻³ g
molar mass = 206 g/mol
number of moles = 0.37 * 10⁻³ g/206 g/mol
number of moles of Pb-206 = 1.79 * 10⁻⁶ moles
For U-238:
mass = 0.95 mg = 0.95 * 10⁻³ g
molar mass = 238 g/mol
number of moles = 0.95 * 10⁻³ g/238 g/mol
number of moles = 3.99 * 10⁻⁶ moles
Assuming that all the Pb-206 were formed from U-238
- Initial moles of U-238 = Moles of present U-238 + molesw of present Pb-208
Initial moles of U-238 = 3.99 * 10⁻⁶ moles + 1.79 * 10⁻⁶ moles
Initial moles of U-238 = 5.78 * 10⁻⁶ moles
One mole of U-238 contains = 6.02 * 10²³ atoms
5.78 * 10⁻⁶ moles of U-238 will contain 6.02 * 10²³ * 5.78 * 10⁻⁶ atoms
Number of atoms of U-238 initially present = 3.48 * 10¹⁸ atoms
Therefore, the number of atoms of U-238 initially present is 3.48 * 10¹⁸ atoms

Zn(s) \ Zn²⁺(aq,0.100 M) // Zn²⁺(aq, x M) \ Zn(s)
voltage = 16 mV x (1V / 10³ mV) = 16 x 10⁻³ V
- In the cell notation, the concentration on the left is that of the anode and that on the right is that of the cathode.
- Oxidation takes place at the anode and reduction takes place at the cathode.
so [Zn²⁺]oxidation = 0.100 M
[Zn²⁺] reduction = x M
From Nernst equation:
Ecell = -0.0592 / n log [Zn²⁺] oxidation / [Zn²⁺]reduction
Number of electrons, n = 2. Substitute and solve for x:
16 x 10⁻³ V = - 0.0592 / 2 log (0.100 /x)
log 0.100 / x = - 0.54
0.100 / x = 0.288
x = 0.347
So the concentration of Zn²⁺ at the cathode = 0.406
