Answer:
Explanation:
You have an acid that is acidic or a base that is basic. When you mix the two, they form water (assuming those are bronsted-lowry acids and bases) which is neutral.
Answer
Atom is the smallest particle of an element.
Hope this helps you!!
<u>Given:</u>
Charge on potassium (K) = +1
Charge on selenium (Se) = -2
<u>To determine:</u>
The values of X and Y in K(X)Se(Y)
<u>Explanation:</u>
The molecule which is formed between K and Se is neutral.
The K+ and Se2- ions should combine such that the net charge on the molecule is zero.
X(K+) + Y(Se2-) = 0
X(+1) + Y(-2) = 0
The simplest solution to the above equation is obtained when X = 2 and Y = 1
Thus, the molecule would be: K₂Se₁
Ans: X = 2 and Y = 1; K₂Se₁
25/2 and 96/X
CROSS MULTIPLY.
2x=2,400.
divide by 2.
x=1,200.
you take the GIVEN MASS of an element, and you put it on top, the coefficient is what it’s over. i believe this is right
The signs of ΔS° and ΔH° will be negative.
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
Combustion reactions must involve O2 as one reactant.
Consider the combustion of butane gas:
C₄H₁₀(g ) + 13/2O₂(g) → 4CO₂(g) + 5H₂O(g)
4 + 13/2 4 + 5
10.5 mol -------------> 9 mol
As the number of moles decreases entropy will decrease
so ΔS° = negative
since this example for combustion reaction heat is released (exothermic)
so ΔH° = negative.
