Explanation:

Answer:

A. grasses begin to grow in soil with organic matter

B. tress begin to grow in thick rich soil

C. mosses begin to grow in thin rocky soil

D. lichens begin to cover bare rock

It would be B. because that comes last.

Explanation:

Whenever a volcano erupts, it puts a layer of rock over everything. Basically, over years and years, lichens will start growing and breaking down the rock. A bunch of years later, mosses will begin to grow in the "soil" that the lichens broke down. When the rocky dirt becomes actual dirt, grasses will start to grow. After that shrubs, and then trees.

1. A 10.0 g sample of propane, C3H8, was combusted in a constant-volume bomb
calorimeter. The total heat capacity of the bomb calorimeter and water was 8.0
kJ/°C. The molar heat of combustion of propane is -2 222 KJ/mol. If the starting
temperature of the water was 20 °C, what will be the final temperature of the
bomb calorimeter?

Answers

Answer:

The final temperature of the bomb calorimeter is 82.98°C

Explanation:

The given information are;

The mass of the propane sample =  10.0 g

The heat capacity of the bomb calorimeter = 8.0 kJ/°C

The molar heat of combustion of propane is -2,222 kJ/mol.

The starting (initial) temperature of the water, T₁ = 20°C

The final temperature of the bomb calorimeter = T₂

The molar mas of propane = 44.1 g/mol

The number of moles, n, of propane present in 10.0 g of propane is found as follows;

\(Number \ of \ moles \ of \ propane, \ n = \dfrac{Mass \ of \ propane}{Molar mass \ of \ propane} = \dfrac{10}{44.1} = 0.227 \ moles\)Which gives;

The heat, Δh, released from the combustion of 10.0 g of propane = 0.227 × -2222 kJ/mol  

Δh = -503.85 kJ/mol  

Heat gained by the calorimeter = Heat released from the combustion of 10.0 g of propane = 503.85 kJ/mol  

Change in heat, Δh\(_c\) in the calorimeter = Heat capacity × Temperature change

Δh\(_c\) = m × C

503.85 kJ/mol = 8.0 kJ/°C × (T₂ - 20°C)

T₂ = -503.85 kJ/mol/(8.0 kJ/°C) + 20°C = 82.98°C

The final temperature of the bomb calorimeter = 82.98°C

If you are leading a team to clean an oil spill in rough waters, which of the following methods would be most effective to clean the oil?

Answers

Answer:Install booms made from, or with, sorbent materials around the oil spill. 

Explanation:Dispersants and booms and skimmers are the most frequently used methods to clean up ocean oil spills. All methods have advantages and disadvantages. The effectiveness depends on the situation – the amount and type of oil, the ocean currents and tides and the weather.

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?


A: Soil

B. Sunlight

C. Heat

D. Water

Answers

Answer:

The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive.  The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.

B. Sunlight

Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.

Why do you think that the neutron was the last of the atom components to be discovered?

Answers

Answer:

The neutron was the last of the atomic components to be discovered because it does not have an electric charge, making it difficult to detect. It was also not predicted by early atomic theories, leading scientists to believe that the atomic nucleus was composed solely of protons. The discovery of the neutron required the development of new experimental techniques, such as neutron scattering, to detect its presence.

it doesn’t have a charge so it was harder to detect.
