Answer:
none
Explanation:
It is given that there are 3 cats.
Each of the cats die with different diseases. One of cats died due to heart failure, the second cats died because of brain tumor and the third cat died due to an experiment gone wrong.
So there are none of the cats left out. All the cats died due to different reasons.
<span>Biological specimens have been preserved in alcohol and formalin for many years.This could damage the specimen and change the colour of the fluid.Engineered fluids are now used as a substitute for formalin as it is a more sustainable medium..Novec fluids which are low in toxicity are also used.</span>

Answer:
True
Explanation:
Both work because an element would be pure and compounds can be split into elements. This will work unless the substance isnt chemcially pure, but in this case it is so the answer would be true.
Answer:
50 mol CH₄
Explanation:
The question is incomplete so I looked it up online.
<em>How many moles CH₄, are needed to produce 50 moles of CO₂?</em>
Step 1: Write the balanced equation for the complete combustion of methane
CH₄ + 2 O₂ ⇒ CO₂ + 2 H₂O
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CH₄ to CO₂ is 1:1.
Step 3: Calculate the number of moles of CH₄ needed to produce 50 moles of CO₂
We will use the previously established molar ratio.
50 mol CO₂ × 1 mol CH₄/1 mol CO₂ = 50 mol CH₄
