Oxygen bodyworkers origins of substations in water and lowers in the amount of dissolve the oxygen killing fish but it’s all gonna be OK because the carbon dioxide equals to killing fish drinking water so you don’t have a C stroke

Answer:

Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.

Explanation:

Fecal coliform are species of bacteria that are found in the intestine of warm-blooded animals like humans etc. Hence, they are released whenever they excrete feaces. Due to this reason, the presence of fecal coliform bacteria in a water body indicates fecal discharge into that water.

The presence of excessive fecal coliform in a water body increases the amount of organic substances in the water. These organic substances are decomposed by bacteria, which causes the oxygen present in the water body (dissolved oxygen) to deplete/decrease. The depletion of oxygen in the water threatens aerobic aquatic organisms e.g fishes and they ultimately suffocate and die.

Answer:

In 1859, European rabbits (Oryctolagus cuniculus) were introduced into the Australian wild so that they could be hunted. ... These rabbits are extremely adaptive, which has played a role in their spread across the Australian continent. All the rabbits need is soil that is fit to burrow and short grasses to graze on.

A 10.0-gram sample of H2O(l) at 23.0°C absorbs 209 joules of heat. What is the final temperature of the H2O(l) sample?(1) 5.0°C

Aliun [14]

The specific heat capacity of water is 4200J/(kg*℃). So when absorbs 209 joules, the water sample will increase 209/(4200*0.01)=5℃. So the final temperature of sample is 23+5=28℃.

Duncan knows that it takes 36400 cal of energy to heat a pint of water from room temperature to boiling. However, Duncan has pre

brilliants [131]

Answer:

$\large \boxed{\text{122 000 J}}$

Explanation:

1. Calculate the energy needed

$\text{Energy} = \text{0.800 pt} \times \dfrac{\text{36 400 cal}}{\text{1 pt}} = \text{ 29 120 cal}$

2. Convert calories to joules

$\text{Energy} = \text{29 120 cal} \times \dfrac{\text{4.184 J}}{\text{1 cal}} = \textbf{122 000 J}\\\\\text{The water will have absorbed $\large \boxed{\textbf{122 000 J}}$}$

Number of

SpyIntel [72]

Answer:

A = 8

B = 8

C = O ( Oxygen )

D = 26

E = 30

F = Fe (Iron)

Explanation:

1)To get "A" we use the following formula

mass number = number of protons + number of. neutrons

15 = number of protons + 7

15 - 7 = number of protons

8 = number of protons

A = 8

2)To find "B"

atomic number = number of protons

Atomic number = 8

B = 8

3)To find "C"

the atomic number is 8 so the element which

has 8 atomic number on periodic table is Oxygen.

C = oxygen

4) To get "D"

Number of protons = atomic number

number of protons = 26

D = 26

5)To get "E"

mass number = number of protons + number of. neutrons

56 = 26 + number of neutrons

56 - 26 = number of neutrons

number of neutrons = 30

E = 30

6) To find "F"

The atomic number is 26 so the element which has 26 atomic number on periodic table is Iron.
