Answer:
506kg
Explanation:
From the reaction equation, we can see that 3 moles of hydrogen yielded 2 moles of ammonia.
Now we need to calculate the number of moles of hydrogen reacted. This mathematically equals the mass of hydrogen reacted divided by the molecular mass of the hydrogen molecule.
The mass of hydrogen reacted is 89.5kg. This equals 89.5 × 1000g which equals 89500g. The molecular mass of hydrogen is 2g/mole ( 1 atom of hydrogen has an atomic mass unit of 1 and 1 molecule of hydrogen has 2 atoms).
Now we mathematically calculate the number of moles of hydrogen reacted to be 89500/2 which equals 44,750 moles.
If 3 moles of hydrogen yielded 2 moles of ammonia gas, then 44, 750 moles will yield 44,750 × (2/3) which equals 29,833 moles of Ammonia gas.
Now, let's calculate the mass of Ammonia gas yielded. This mathematically equals the number of moles of ammonia gas yielded multiplied by the molar mass of ammonia gas. The molar mass of ammonia gas is (14 + 3(1)) which equals 17g/mole.
Hence, the mass yielded equals 29,833 × 17 = 506167g
This equals 506,167 ÷ 1000 = 506.167kg.

option A is correct answer
Answer:
2Na⁺ (aq) and 2OH⁻(aq)
Explanation:
Spectator ions:
Spectator ions are those ions which are same on both side of chemical reaction. These ions are same in the reactant side and product side. Their presence can not effect the chemical equilibrium that's why when we write the net ionic equation these ions are neglect or omitted.
Given ionic equation:
Ba⁺²(aq) + 2OH⁻(aq) + 2Na⁺ (aq) + CO²⁻₃(aq) → BaCO₃(s) + + 2Na⁺ (aq) + 2OH⁻(aq)
In given ionic equation by omitting the spectator ions i.e, 2Na⁺ (aq) and 2OH⁻(aq) net ionic equation can be written as,
Net ionic equation:
Ba⁺²(aq) + CO²⁻₃(aq) → BaCO₃(s)
The quantity of β-hydroxybutyrate the bear can produce
during hibernation is 3,073.30grams.
Hibernation is defined as the period of less activity by animals to conserve energy to survive coarse weather conditions.
A typical example of an animal that hibernates is the bear.
From the question, a bear is able to accumulate 25kg (25000grams) of triglyceride.
To calculate quantity of β-hydroxybutyrate that would be produced from 25kg triglyceride;
846g of triglyceride = 104grams of β-hydroxybutyrate
25000g of triglyceride = x grams
(Cross multiple to solve for x grams)
X = 104 × 25000/846
Therefore, the quantity of β-hydroxybutyrate the bear can produce during hibernation is 3,073.30grams.

Answer:
The pressure inside the bottle is 92.678 atm.
Explanation:
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
×××
In this case:
P= ?
V= 500 mL= 0.500 L
n= 60 g* = 2.07 moles
R= 0.082
T= 0 C= 273 K
Replacing:
P* 0.500 L= 2.07 moles* 0.082 * 273 K
Solving:
P= 92.678 atm
The pressure inside the bottle is 92.678 atm.
