Answer:
find how much gold weighs by volume based on the karat and factor that in to find the answer
Explanation:
Answer: 1.47
Explanation:
The combined gas equation when pressure is constant:
where,
=original number of moles of air in the balloon = ?
= number of moles of air in the heated balloon = ?
= initial volume of gas = 
= final volume of gas = 
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get the final pressure of gas.
Therefore, the ratio of the number of moles of air in the heated balloon to the original number of moles of air in the balloon is 1.47
The answer is Algae.
<span>Abiotic factors are non-living things of an ecosystem. Abiotic factors include landscape, climate, pH, salinity and other physical features of the ecosystem. On the other hand, there are b</span>iotic factors. Biotic factors are living things in the ecosystem. Those are plants, animals, and other organisms. Since Algae are living-things, they are biotic factors unlike pH, salinity, and climate which are abiotic factors.
CH4+2O2–> CO2+2H2O
-count the number of atoms of each element on each side of the reaction arrow, there is 1 carbon,4 hydrogen, and 2 oxygen on the reactant side and 1 carbon, 2 hydrogen, and 3 oxygen on the product side.Then add coefficients so the number of atoms of each element is the same on both sides of the equation
