Nancy learned in school that composting is a way to cycle nutrients, and as tiny ecosystems, composting requires biotic and abio

tic factors. She found four lists with ingredients to add to her compost in addition to the kitchen food scraps.
List

Biotic factors

Abiotic factors

1

fungi

worms

water

sun

2

water

worms

rocks

light

3

worms

fungi

leaves

sun

4

water

sun

fungi

worms

Which list matches with the information she received in school and why are the ingredients a good choice?
A
List 1, because it has a balance between biotic decomposers and abiotic factors needed for the worms and composting.
B
List 2, because worms and water are the only biotic factors needed. Worms as decomposers, and the water for the worms to live.
C
List 3, because the abiotic decomposers, leaves and sun provide an excellent environment for worms and fungi to start composting.
D
List 4, because for the abiotic factors to decompose the kitchen scraps, they need plenty of water and sun.

dybincka [34]

Answer : The partial pressure of the hydrogen is, 705.9 mmHg

Explanation :

According to the Dalton's law of partial pressure,

P_T=P_{H_2}+P_{H_2O}

where,

P_T = total pressure of the gas = 729.7 mmHg

P_{H_2} = partial pressure of the hydrogen gas = ?

P_{H_2O} = partial pressure of the water = 23.8 mmHg (standard value)

Now put all the given values in the above expression, we get:

729.7mmHg=P_{H_2}+23.8mmHg

P_{H_2}=705.9mmHg

Therefore, the partial pressure of the hydrogen is, 705.9 mmHg

135-g sample of a metal requires 2.50 kJ to change its temperature from 19.5 C to 100.0 C what is the specific heat of this meta
Harman [31]
The temperature increase is from 19.5 to 100 degrees centigrade or 80.5 degrees centigrade. The calorie increase is 2.50 x 1000 x 0.238902957619 or a total of 597.25 calories. 597.25/80.5 = 7.419 calories per degree centigrade. 7.419/135 grams = 0.0549 calories/gram/degree centigrade. The conversion from kilo joules involves multiplying the calories per joule x 1000 to get the number of calories in one kilo joule and then by the 2.5.
