I. Because they're a limited resource
2 Because they're a cause of carbon pollution.
Answer:
6.00 moles of sodium permanganate
Explanation:
Let us attempt to count the number of atoms present in sodium perchlorate. The formula of the compound is NaClO4
Sodium atoms - 1
Chlorine atoms - 1
Oxygen atoms -4
Total number of atoms = 6
Among the options, only KMnO4 also has six atoms. One atom of potassium, one atom of manganese and four atoms of oxygen.
Answer:
The work done on the system is 17.75_KJ
Explanation:
To solve this question we need to know the required equations from the given variables, thus
Initial volume = 85L
Final volume = 12L
External pressure = 2.4 atm.
work done = - PΔV
2.4×(85-12) = 175.2L×atm
Converting from L•atm to KJ is given by
1 L•atm = 0.1013 kJ
(175.2 L•atm) * (0.1013 kJ / 1 L•atm)
= 17.75 kJ
The work done on the system is 17.75_KJ
Answer:
What is the total number of valence electrons in the Lewis structure of nh4+?
Total valence electrons pairs
Total electron pairs are determined by dividing the number total valence electrons by two. For, NH4+, Total pairs of electrons are 4.

Hope it helps! Correct me if I am wrong :>
Im sure about my answer :>
Can you please mark me as brainlest?
Where is the model? I do know salt water is a mixture though
