it will be called verbatim plagiarism, also called direct plagiarism
Answer:
Gas to liquid
Explanation:
As the atoms temperature decreases, the kinetic energy of the atom decreases. Besides if it is turning to solid the atoms will be fixed position,they wont pass each other. So it here is forming to become a liquid
<u><em>Answer:</em></u>
2 H₂O ............> 2 H₂ + O₂
<u><em>Explanation:</em></u>
<u>To balance a chemical equation,</u> we need to make sure that the number of moles of each element on the reactants side is equal to the number of moles of that elements on the products side.
<u>For the given equation:</u>
H₂O ............> H₂ + O₂
<u>We need to make sure that:</u>
number of moles of reacting hydrogen = number of moles of produced hydrogen
number of moles of reacting oxygen = number of moles of produced oxygen
<u>1- Let's check the Oxygen:</u>
On the reactant side, we have one mole of oxygen
On the products side, we have two moles of oxygen
To balance this, we can multiply the reactants side by 2.
<u>This will give us:</u>
2 H₂O ............> H₂ + O₂
<u>2- Let's check the Hydrogen:</u>
From part 1, we reached the following equation:
2 H₂O ............> H₂ + O₂
From this equation, we can note that:
On the reactant side, we have 2*2 = 4 moles of hydrogen
On the products side, we have 2 moles of hydrogen
To balance this, we can multiply the hydrogen in the products side by 2
<u>This will give us:</u>
2 H₂O ............> 2 H₂ + O₂
<u>3- Let's check:</u>
The equation we reached in part 2 is:
2 H₂O ............> 2 H₂ + O₂
Checking this equation, we can find that:
We have 2*2 = 4 hydrogen moles on reactants side and 2*2 = 4 hydrogen moles on products side
We have 2 oxygen moles on reactants side and 2 oxygen moles on products side
<u>Therefore,</u>
The equation is balanced
Hope this helps :)
Answer:
oxalate, fluoride, carbonate, phosphate.
Explanation:
It is important to consult the solubility chart in order to determine the anions.
Any compound with a low Ksp means the compound is very insoluble.
Hence, it means the formation of this compound is favoured strongly and its dissolution which would liberate calcium ions is unfavoured.
Any compound with a low Ksp would therefore "soak up" all the free calcium and will thus not be present in the solution.
Using solubility chart and noting the compounds with a low Ksp value, the anions that are probably present are: oxalate, fluoride, carbonate, phosphate.
There are 115 protons in the element 115 and due to the large number of protons, the element does not exist in nature.
Also, the element can not be isolated in nature that is IUPAC had to require an independent confirmation of the element.
<h3>What is element 115?</h3>
We know that the periodic table is an arrangement of the atoms in order of increasing atomic number. We know that the larger the atomic number of the element, the less likely that the element would be stable in nature. The element that have been named 115 is called Moscovium and was discovered in Moscow as a product of a radioactive experiment. The number of protons in element 115 is 115 protons
Generally, the element number 115 does not exist in nature because if the proton number in an element exceeds 82, the repulsion between the protons would make it almost impossible for the nucleus to be a stable nucleus.
The reason why IUPAC had to request an independent confirmation of the element is because it does not exist in nature.
