Answer:
Bycatch can negatively affect species such as dolphins, sea turtles, protected fish, and whales by harming animals, contributing to population declines, and impeding population recovery. Other impacts of fisheries on marine mammals may include removal of their preferred prey and sometimes habitat damage.
Explanation: hey could i get to kno u or sum
Answer:
Q = 0.144
Explanation:
- C(s) + H2O(g) ↔ CO(g) + H2(g)
reaction quotient:
- Q = [H2(g)][CO(g)] / [H2O(g)][C(s)]
∴ [C(s)] = 10.0 mol/2.50 L = 4 M
∴ [H2O(g)] = 16.0 mol/2.50 L = 6.4 M
∴ [CO(g)] = 3.30 mol/2.50 L = 1.32 M
∴ [H2(g)] = 7.00 mol/2.50 L = 2.8 M
⇒ Q = (2.8 M)(1.32 M) / (6.4 M)(4 M)
⇒ Q = 0.144

Explanation:
Answer:
90.5mL is the volume of the gas at STP
Explanation:
It is possible to find volume of a gas when conditions of temperature and pressure change using combined gas law:
Where P is pressure, V is volume and T is absolute temperature. 1 is initial conditions and 2 final conditions.
If initial conditions are 1.08atm, 80.0mL and absolute temperature is (-12.5°C + 273.15) = 260.65K.
And STP are 1atm of pressure and 273.15K of absolute temperature. Replacing:
V₂ = <em>90.5mL is the volume of the gas at STP</em>
7.66g of ethyl butyrate is produced.
The reaction is
CH₃CH₂CH₂COOH + CH₃CH₂OH ----> CH₃CH₂CH₂COOCH₂CH₃
- The molar mass of butanoic acid is 88.11g/mol
- We have 7.45g of butanoic acid
- The moles of butanoic acid we have is 7.45/88.11 = 0.0845 mol
- If the yield is 100%, 1 mole of butanoic acid gives 1 mole of ethyl butyrate
- But the reaction yield is 78%
- 1 mole of butanoic acid gives 0.78 mole of ethyl butyrate
From 0.0845 mol of butanoic acid we get 0.78 x 0.0845 = 0.66 mol of ethyl butyrate.
The molar mass of ethyl butyrate is 116.16g/mol
So 0.66 x 116.16 = 7.66g
7.66g of ethyl butyrate is produced.
