Explanation:
Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.
In your case, the balanced chemical equation for this synthesis reaction looks like this
2
H
2(g]
+
O
2(g]
→

Notice that the reaction requires
2
moles of hydrogen gas and
1
mole of oxygen gas to produce
2
moles of water.
This tells you that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction.
You know that your reaction uses
6.0
moles of oxygen. Assuming that hydrogen gas is not a limiting reagent, you can say that the reaction will produce
6.0

Answer:
The correct answer is that as the temperature have increased the range of the lionfish has changed. The lionfish are native to the tropical waters of the Indo-Pacific region. The climatic change will increase the temperature of water and this will lead to the increase in the population of the fishes.
Explanation:
If you were referring to the law of conservation of mass when a gas is produced it is difficult to prove that because it would be virtually impossible to measure the mass of gas in a container as it would probably be similar and density the air

Answer:volume of rock = 90cm³-50cm³=40cm³
density=mass/volume =10/40 =0.25g/cm³
Explanation:we can also write it as 2.5kg/m³
