Answer:
statement best describes the total number of carbon atoms during cellular
respiration in the fish is :
The total number of carbon atoms stays the same because the carbon from the carbon-containing food molecules is used to make molecules such as carbon dioxide
Explanation:
Respiration : It is a process in which energy from the "food" molecule is released in the form of ATP
ATP = Adenosine Triphosphate
There are two kind of respiration process:
1. In the presence of O2 = Aerobic Oxidation
2. In the absence of O2 = Anaerobic Oxidation
The breakdown of food into CO2 occur by three main process:
Glycolysis
Krebs cycle
Phosphorylation
The reaction for the Decomposition of the Glucose molecule is written as:
It is a oxidation - reduction reaction(Redox).
Here one substance is oxidised and other is reduced.
The number of Carbon atoms in reactant =6
It will produce = 6 CO2 in which the number of C=6
Hence ,
The total number of carbon atoms stays the same because the carbon from the carbon-containing food molecules is used to make molecules such as carbon dioxide
Answer:
3.03 g
Explanation:
The first thing to do here is figure out the chemical formula for aluminium hydroxide.
Aluminium is located in group
13
of the periodic table, and forms
3
+
cations,
Al
3
+
. The hydroxide anion,
OH
−
, carries a
1
−
charge, which means that a formula unit of aluminium hydroxide will look like this
[
Al
3
+
]
+
3
[
OH
−
]
→
Al
(
OH
)
3
Now, you can figure out the mass of hydrogen present in
1
mole of aluminium hydroxide by first determining how many moles if hydrogen you get in
1
mole of aluminium hydroxide.
Since
1
mole of aluminium hydroxide contains
3
moles of hydroxide anions, which in turn contain
1
mole of hydrogen each, you can say that you will have
1 mole Al
(
OH
)
3
→
3
a
moles OH
−
→
3
a
moles H
The problem tells you that the molar mass of hydrogen is equal to
1.01 g mol
−
1
. This means that
1
mole of hydrogen has a mass of
1.01 g
.
You can thus say that one mole of aluminium hydroxide contains
3
moles H
⋅
1.01 g
1
mole H
=

3.03 g H

I'll leave the answer rounded to three sig figs. Btw my sister calculated this oof
Answer:
P₂ ≅ 100 atm (1 sig. fig. based on the given value of P₁ = 90 atm)
Explanation:
Given:
P₁ = 90 atm P₂ = ?
V₁ = 18 Liters(L) L₂ = 12 Liters(L)
=> decrease volume => increase pressure
=> volume ratio that will increase 90 atm is (18L/12L)
T₁ = 272 Kelvin(K) T₂ = 274 Kelvin(K)
=> increase temperature => increase pressure
=> temperature ratio that will increase 90 atm is (274K/272K)
n₁ = moles = constant n₂ = n₁ = constant
P₂ = 90 atm x (18L/12L) x (274K/272K) = 135.9926471 atm (calculator)
By rule of sig. figs., the final answer should be rounded to an accuracy equal to the 'measured' data value having the least number of sig. figs. This means P₂ ≅ 100 atm based on the given value of P₁ = 90 atm.
Answer:
A
Explanation:
The only factor that would not decrease the carrying capacity of the fur seal's environment is the population of predators.
<em>The carrying capacity is defined as the maximum number of individuals of a species an environment can sustain based on the resources available. Hence, only a fluctuation in the resources available in the environment of the fur seal can affect the carrying capacity. </em>
<u>Pollution </u>and <u>destruction of the habitat of the fur seal</u> would limit the resources available to the animals and as such, limit the carrying capacity. A <u>fluctuation in the population of prey available</u> for the population of fur seals would also affect the carrying capacity.
The only factor that has no bearing on the carrying capacity of the fur seal's environment is the population of predators. Predators have the capacity to reduce the population of fur seals but not affect the carrying capacity for fur seals.
The correct option is, therefore, A.
