Explanation:
According to the question,
The 100.0 g of carbon dioxide:
= 
= 
We know that 16 moles of 
formation associates with -11018 kJ of heat, then
0.8747 moles formation associates with,
= 
= 
= 
The answer to your question is homogeneous solutions , 6ut i may 6e wrong..
Answer:
Gravity
Explanation:
Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.
Answer:
Explanation:
The nuclear equation from which you have to identify the missing element is:
- ²³⁹₉₄ Pu + ¹₀n → ___ + ¹³⁴₅₄Xe + 3 ¹₀n
The superscripts to the left of each chemical symbol are the mass number of the atoms (number of protons plus neutrons) and the subscripts to the left of the chemical symbols are the atomic numbers of the atoms (number of protons).
Thus, such equation must be read as "an atom of plutonium-239 is bombarded with a neutron and produces one atom of an unkwon element, one atom of xenon-134, and 3 neutrons".
To find the identity of the missing element you must do two balances: mass number and atomic number.
Mass number:
Hence, the mass number of the missing element is 103.
Atomic number:
Hence, the atomic number of the missing element is 40.
In a periodic table you can find that the element with atomic number 40 is zirconium, Zr.
Thus, the identity of the missing isotope is zirconium-103, ¹⁰³₄₀Zr.
And the complete equation is:
- ²³⁹₉₄ Pu + ¹₀n → ¹⁰³₄₀ Zr + ¹³⁴₅₄Xe + 3 ¹₀n
Answer:
Increasing charges on either object
Explanation:
For example, if object A increases in electrons, the electric force between objects A&B will increase
