Explanation:
First find the # of moles of CO2 that results from the combustion of 3.327 mol C3H6:
3.227 mol C3H6 × (6 mol CO2/2 mol C3H6)
= 9.981 mol CO2
Use the molar mass of CO2 to determine the # of grams of CO2:
9.981 mol CO2 x (44.01 g CO2/1 mol CO2)

Explanation:
propose 3 solutions that address that sources of global warming
Answer:
The correct answer is - reduce carbon emission, decrease deforestation snd increase plantation, use renewable energy.
Explanation:
Global warming is the process that is caused by human activities to increase the temperature of the earth. It increases the heat of the climate of the earth that leads to a negative impact on the environment. Increasing the greenhouse gas emission leads to trapping heat and cause global warming.
The three major solutions are:
1. reduce carbon and greenhouse gases: The main cause of global warming is the emission of greenhouse gases and an increase in carbon in the atmosphere, so reduce these gas emissions by avoiding fossil fuels that release carbon.
2. reduce deforestation and increase the plantation: trees take carbon dioxide from the environment, So prevent them from cutting and planting new trees will help reducing carbon from the environment.
3. Using renewable energy will help them to not depend on fossil fuels or water waste that will help in reducing global warming.

Is all the biomass consumed by a primary consumer, such as a brine shrimp, transferred to the secondary consumer, such as a gull, when the brine shrimp is eaten? For instance, if a brine shrimp eats 10 g of algae in its life before the gull eats it, does the gull get 10 g of biomass when it eats the brine shrimp? Why or why not?
Particles diffuse
A. from low concentration to higher concentration
B. from higher concentration to lower concentration
C. at any direction
[tex]\huge{ \mathrm{ \underline{ Answer} \: \: ✓ }}[/tex]
The Correct option is :
[tex] \large \boxed{\mathrm{B.}}[/tex]
The particles diffuse from the region of higher concentration to the region of lower concentration.
for example :
At alveoli -during Inhalation, oxygen is in higher concentration in our lungs but in lower concentration blood capillaries, so oxygen diffuses into the blood and carbon dioxide which is in higher concentration in blood diffuses out from the blood capillaries.

To determine the molar mass of an element, one must know the element's
a. number of isotopes.
b average atomic mass
c avogradro constant
d atomic number
Answer:
d
Explanation:
from you know the atomic number it should be easy to find
To determine the molar mass of an element, one must know the element's atomic number. Therefore, option D is correct.
What is the atomic number ?An element's atomic number (Z) is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the feature that distinguishes each element from all others. Elements differ based on their atomic number.
Because the combined masses of protons and neutrons account for nearly all the mass of a given atom, the atomic mass of a single atom can be calculated by adding the total number of protons and neutrons of that particular isotope.
The atomic mass of any element on the periodic table can be used to calculate its molar mass.
Thus, option D is correct.

. A scientist placed a sample of lithium into a container of water. The scientist observed the lithium floating and making a buzzing sound as gas bubbles were forming around it. Which conclusion is BEST supported by this observation
Answer: The conclusion that best support the observation is that (A CHEMICAL CHANGE took place).
Explanation:
A chemical reaction is defined as the process by which two or more substances, which are often referred to as REACTANTS, combine through bond formation or dissociation of bonds to form new PRODUCTS. In this type of reaction, a CHEMICAL CHANGE occurred because a new substance is formed as a result of the chemical reaction that took place.
There are different characteristics of a reaction which shows that a chemical change has occurred, these includes:
--> Color Change
--> Production of an odor
--> Change of Temperature
--> Evolution of a gas (formation of bubbles)
-- Precipitate (formation of a solid)
From the chemical reaction in the given question, Lithium metals reacts slowly with water to form a colourless solution of lithium hydroxide (LiOH) and hydrogen gas (H2). Here we observe that the buzzing sound of formed gas bubbles shows that a gas was given off. Therefore in conclusion, a CHEMICAL CHANGE took place.
