Answer:
a chain of decays that result in a stable nucleus
Explanation:
Decay series is a series of decay in which radioactive element is decomposed in different elements until it produces one stable atom.
Mountain lion have to hunt other animals up in the Mountains. Other animals are meat. Therefore mountain lions are carnivores, not herbivores.
I hope this helped!
If it did I would like it if I got brainliest :)
Answer:
1.18 moles of CS₂ are produced by the reaction.
Explanation:
We present the reaction:
5C + 2SO₂ → CS₂ + 4CO
5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.
As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:
70.8 g / 12 g/mol = 5.9 moles
Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂
Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles
Answer:
0.628 M.
Explanation:
In order to solve this problem we need to keep in mind the<em> definition of molarity</em>:
- Molarity = moles / liters
We are given both the <em>number of moles and the volume of solution</em>, meaning we can now proceed to <u>calculate the molarity</u>:
- Molarity = 0.220 mol / 0.350 L
The estimated population of the sea turtles for that location is 160 turtles
Let b represent the total turtles in the location.
<h3>Data obtained from the question</h3>
- Captured marked turtle = 15
The estimated turtles in sea can be obtained as follow:
Mark in sea / Total in sea = captured marked turtle / Captured turtle
40 / b = 15 / 60
Cross multiply
b × 15 = 40 × 60
b × 15 = 2400
Divide both side by 15
b = 2400 / 15
b = 160 turtles
Thus, the estimated turtles in the sea is 160 turtles
