Explanation:
how many moles are in 11g of carbon dioxide?
Answer:
0.25 moles
Explanation:
To find number of moles in 11 g of CO2
44 g of CO2 =1 MOLE
1GM of CO2 = 1/44 mole
11 gm of CO2 = 1/44x11
=11/44 mole
= 0.25 mole

They have the exact same name at the first but the yacca plant must be eaten by the yacca moth because if the animal doesn't eat it will die of hunger
Answer:
its B
Explanation:
The relationship between yucca moths and yucca plants is an example of obligate mutualism. Many species of yucca plant can be pollinated by only one species of yucca moth, while those yucca moths use the yucca flowers as a safe space to lay their eggs.

Explanation:
Compare and contrast the molecular activity of solids, liquids, and gases.
Answer:
The molecules in a solid are close together and they vibrate in place. The molecules in a liquid move quickly and farther apart from eachother. The particles in a gas move freely at high speeds and slide past eachother.
What mass of the protein gelatin is needed to make 0.5 L of a 3 g/L gelatin solution? Show your work.
Answer:
m = 1.5 gram
Explanation:
Given that,
Density of protein gelatin, d = 3 g/L
The volume of protein gelatin, V = 0.5 L
We need to find the mass of the protein gelatin. The density of an object is given by :
d = m/V
Where
m is mass
[tex]m=d\times V\\\\m=3\ g/L\times 0.5\ L\\\\m=1.5\ g[/tex]
So, the required mass is 1.5 gram.
Carbohydrates like sugars and starches are made of only three elements: carbon (C), hydrogen (H), and oxygen (O). How is it possible that so many different carbohydrates can be formed using only these three elements?
Answer:
See explanation
Explanation:
A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.
Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.
This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.
The information regarding the different carbohydrates that should be formed is explained below.
Carbohydrates:It should be created from carbon, hydrogen, and oxygen. It should be combined with every carbohydrate. Still, carbohydrates should be comprised of only these three atoms, so the no of atoms of these elements in every carbohydrate also the spatial arrangement of these atoms in every carbohydrate is not similar.
This represents that various carbohydrates contain distinct numbers of carbon, oxygen, and hydrogen atoms that are in different ways in space.

answer: Stoichiometry is a big word for a process that chemist’s use to calculate
amounts in reactions. It makes use of the coefficient ratio set up by balanced
reaction equations to make connections between the reactants and products
in reactions.
Stoichiometry calculates the quantities of reactants and products in a
chemical reaction. The equation must be balanced!
Questions that deal with amounts in reactions are examples of reaction
stoichiometry. We already have the tools necessary to solve this question.
We just need to learn a new way to apply skills such as writing chemical
formulas, calculating formula masses, and converting from mass to moles,
particles to moles, and volume of gases to moles.
Mole to Mole Conversions- you must have the Mole Ratio.
Illustration:
Let’s use an analogy that we can understand to begin to understand the process.
The KEY to any mole conversion is the ratio of coefficients in the reaction
equation. Say I want to make a bacon double cheeseburger. Let’s get our recipe
together.
1 hamburger bun + 2 hamburger patties + 2 slices of cheese + 4 strips of bacon →
1 bacon double cheeseburger
Based on this recipe:
1) If I have five bacon double cheeseburgers:
a. How many hamburger buns did you use? → 5 hamburger bun
b. How many hamburger patties did you use? → 10 hamburger patties
c. How many slices of cheese did you use? → 10 slices of cheese
d. How many strips of bacon did you use? → 20 strips of bacon
2) How many bacon double cheeseburgers can you make if you start with:
a. 2 buns, 4 patties, 4 slices of cheese, 8 strips of bacon
2 bacon double cheese burgers
b. 1 dozen buns, 2 dozen patties, 2 dozen slices of cheese, 4 dozen strips of bacon
1 dozen bacon double cheese burgers

The specific heat of a substance represent the ability of a substance to hold heat. Therefore, the correct option is option B.
What is specific heat of a substance?The amount of heat needed to raise a substance's temperature by one degree Celsius in one gram, also known as specific heat. Typically, calories as well as joules for every gram per degree Celsius are used as the measures of specific heat.
The notion of specific heat was developed by the Scottish scientist William Black in the 18th century as a result of his discovery that identical quantities of different substances required varying quantities of heat to raise them within a comparable temperature range. The specific heat of a substance represent the ability of a substance to hold heat.
Therefore, the correct option is option B.
