Answer:
Below
Explanation:
The coefficients in a chemical reaction are called stochiometric coefficients
they represent the number of atoms or molecules they are multiplied to.
A chemical reaction has generally this form:
Answer:
C.
Explanation:
Noble gases are stable and already have a full outter shell therefore don't tend to lose or gain any electrons.
Answer:
The answer to your question is Q = 355.64 J
Explanation:
Data
Heat = Q = ?
Temperature 1 = T1 = 20°C
Temperature 2 = T2 = 37°C
mass = m = 5 g
Specific heat = Cp = 4.184 J/g°C
Formula
Q = mCp(T2 - T1)
-Substitution
Q = (5)(4.184)(37 - 20)
-Simplification
Q = (5)(4.184)(17)
-Result
Q = 355.64 J
<span>Lewis structure for 3 nitrogen-containing compounds can be drawn as:
</span>
:N:::N: , ::N:H
For the Lewis Structure for N₃⁻, we place a double bond between the Nitrogen atoms to complete the outer shells on all atoms and we will only use the available valence electrons for the molecule. <span>There are 16 valence electrons available.</span>
This reaction contains pure solids which are not considered when writing out equilibrium constant expressions.
O2...........SO2
I 2.9...........0
C -x.......... +x
E 2.9-x........ x
Q=0/2.9 = 0 ---->Q<K Reaction will go to the right
Since the coefficients are all 1, I won't bother putting in the exponents.
k=B/A
1.5= x / (2.9-x)
4.35 - 1.5x = x
2.5x = 4.35
x= 1.74
plug back in ice chart
2.9 - 1.74
=1.16
=1.2 ANSWER
