Impossible to form from given reactants
Explanation:
Only sodium has carbonate ion here .so only possible way to displace carbonate is to use potassium
When sodium carbonate and Potassium iodide react with each other double displacement reaction occurs
As potassium is powerful than sodium it displaces sodium to form potassium carbonate .
Then you have to use water and then you can use calcium suppliment .
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. ... The closeness, arrangement and motion of the particles in a substance change when it changes state.
Answer:
A. 25Mn45^+
B. 45Rh69^+2
C. 53I142^-
D. 97Bk^243
Explanation:
Generally Atomic mass (A)= no of protons (p) + no of neutrons (n)
No of Neutrons (n)=A-p
No of protons = Atomic number
Symbol for nulclide: zX^A
Z is Atomic number, A is Atomic mass
And X is symbol of element
<h2>Answer:</h2>
<u>The correct answer is</u><u> B</u>
<h2>Explanation:</h2>
Waves which are located on the ocean's surface are commonly produced by the wind which is transferring its energy to the water. Huge and big waves, or swells, can travel over long distances. The size of the wave depends on wind speed, wind duration, and the area over which the wind is blowing. If The speed of the wind is more, it stays for along time and it covers a larger distance then the waves produced will be very powerful and large.
Answer:
82.15g of Cyclohexene
Explanation:
The reaction of dehydration of cyclohexanol (CycOH) to cyclohexene (CycENE) is:
CycOH + H₃PO₄ → CycENE + H₂O
<em>That means, 1 mole of cyclohexanol produce 1 mole of cyclohexene.</em>
Now, theoretical yield is defined as the maximum amount of product that could be obtained.
Thus, 100.16g of cyclohexanol could give as theoretical yield of cyclohexene:
100.16g CycOH × (1 mol / 100.16g) = 1 mole of CycOH = 1 mole of CycENE (Assuming a theretical yield).
1 mole CycENE × (82.15g / mol) =
<h3>82.15g of Cyclohexene</h3>
