Answer:
The carrying capacity of this population would be 125 we know this because we see that this number occur multiple times and seems to be the tipping point after which the number of the population always go down
D. 1,1,2,1
<h3>Further explanation </h3>
Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
- 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.
- 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product
- 3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction(unbalanced)
Zn+K₂CrO₄ ⇒ K + ZnCrO₄
Give coefficient
aZn+K₂CrO₄ ⇒ bK + cZnCrO₄
Zn, left=a, right=c⇒a=c
K, left=2, right=b⇒b=2
Cr, left=1, right=c⇒c=1⇒a=1
O,left=4,right=4c⇒4c=4⇒c=1
Reaction(balanced0
Zn+K₂CrO₄ ⇒ 2K + ZnCrO₄
Answer:
A- Speed = distance/time
Explanation:
Would make sense and that's what I remember
Answer is: <span>the empirical formula of the hydrocarbon is CH</span>₂.<span>
Chemical reaction: C</span>ₓHₐ + O₂ → xC + a/2H₂O.<span>
m(CO</span>₂) = 33.01 g.
n(CO₂) = m(CO₂) ÷ M(CO₂).
n(CO₂) = 33.01 g ÷ 44.01 g/mol.
n(CO₂) = n(C) = 0.75 mol.
m(H₂O) = 13.52 g.
n(H₂O) = 13.52 g ÷ 18 g/mol.
n(H₂O) = 0.75 mol.
n(H) = 2 · n(H₂O) = 1.5 mol.
n(C) : n(H) = 0.75 mol : 1.5 mol /0.75 mol.
n(C) : n(H) = 1 : 2.
