Answer:
56.9 mL
Explanation:
To solve this problem, we can use the equation of state for an ideal gas, which states that:
where
p is the pressure of the gas
V is its volume
n is the number of moles in the gas
R is the gas constant
T is the absolute temperature of the gas
For a gas undergoing a transformation, n and R remain constant, so we can rewrite the equation as:
where in this case:
is the initial pressure of the gas
is the initial volume
is the initial temperature of the gas
is the final pressure (at STP)
is the final temperature (at STP)
Solving for V2, we find the final volume of the gas:
Adding decimals has steps to follow not like the whole number when adding, you can add it straight.
Given:
3.089 g and 0.074 52 g
The first step arranged the numbers and second lined up the decimal points when writing down and then simply add the numbers that lined up in the decimals points.
3.089
+ 0.07452
3 .16352
so, you can easily get the answer 3.16352 g.
Answer:
Two ecosystems might have different species of plant this is as a result of the nature of the ecosystem and the ability of plants to thrive in them.
Explanation:
An ecosystem can be defined as a community of organisms living together and interacting with their physical environment. There are different types of ecosystems but they are all categorized under terrestrial and aquatic habitats. They include forests, grasslands, deserts, freshwater and marine.
In the desert ecosystem an example of a plant that grows there is the cactus plant, this is as a result of their ability to conserve water.
In freshwater ecosystem, an example of a plant found there is the waterlily this is due to their unique ability to survive on water surfaces.
These different plant species are affected by different limiting factors in their ecosystems such as temperature, sunlight, nutrients.
