The balanced equation shows how sodium chloride reacts with silver nitrate to form sodium nitrate and silver chloride. NaCl AgNO3 Right arrow. NaNO3 AgCl If 4. 00 g of NaCl react with 10. 00 g of AgNO3, what is the excess reactant? AgCl NaCl AgNO3 NaNO3.
The reactant that has been present in excess in the reaction has been NaCl. Thus, option B is correct.
The balanced chemical equation has been:
[tex]\rm NaCl\;+\;AgNO_3\;\rightarrow\;NaNO_3\;+\;3\;AgCl[/tex]
From the balanced equation, for complete utilization of 1 mole of sodium chloride, 1 mole of silver nitrate has been used.
The moles of can be given as:
[tex]\text Moles\;=\;\dfrac{m}{mwt}[/tex]
Where, mass of Silver nitrate, [tex]m=10\;\text g[/tex]
Molecular mass of silver nitrate, [tex]mwt=168\9.87\;\text {g/mol}[/tex]
Substituting the values, moles of silver nitrate has been:
[tex]\rm Moles \;AgNO_3=\dfrac{10}{169.87} \\Moles \;AgNO_3=0.058\;mol[/tex]
Mass of sodium chloride, [tex]m=4\;\text g[/tex]
Molecular mass of sodium chloride, [tex]mwt=58.44\;\text {g/mol}[/tex]
Substituting the values, moles of sodium chloride has been:
[tex]\rm Moles\;NaCl=\dfrac{4}{58.44}\\Moles\;NaCl=0.068\;mol[/tex]
From the balanced chemical equation,
[tex]\rm 1\;moles\;AgNO_3=1\;moles\;NaCl\\0.058\;mol\;AgNO_3=0.058\;mol\;NaCl[/tex]
Since, the available moles of NaCl has been 0.06 mol, and used NaCl has been 0.05 mol. Thus, NaCl has been the excess reactant. Hence, option B is correct.

pls answer thisss it's due today
Answer:
1.correct
3.correct
Explanation:
pls mark me as brainliest
Answer:
I believe A is the correct answer.
Explanation:
I note that another response includes C. as another correct answer. It is possible, but it depends on what is meant by "fixed shape." I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own. Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition. But a primary definition of gases is that that take on the shape of their container, not a shape of their own.
A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws). They may have interactions, and often do, but they are weak. That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.
10 facts about “molecules”
Answer:
Explanation:
A perfect diamond is a single molecule made of carbon atoms.
DNA is a super long molecule that has information uniquely describing every human being.
When two or more atoms chemically bond together, they form a molecule.
They are very small in size.
They have space between them.
They are in constant random motion.
molecules move when Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
In 1926, French physicist Jean Perrin received the Nobel Prize in physics for proving, conclusively, the existence of molecules.
Molecules can exist in free state because they are very stable.
The smallest particle of a compound capable of existing on its own is a Molecule-not a atom.
mass is the gravitational pull on the earth
-tru
-fals
plz help
Answer:
I believe the answer is false
Explanation:
Earth's gravity comes from all of its mass. All the mass makes a combined gravitational pull on all the mass in an object. If you were on a planet with less mass than Earth, you would weigh less than you do here. Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. Mass is not the gravitational pull on the earth.
Jacinta wrote the following passage about chemical changes.
A chemical change is a change that results in one or more new substances with different properties. When a chemical change occurs, the new substance can give off an odor, such as rotting fruit or cookies baking in the oven. Chemical changes can cause color changes, such as iron rusting and turning a reddish-brown color. When wood is burned or ingredients are mixed for baking a cake, a new substance is made.
Choose the best statement that Jacinta can add to her passage.
Chemical changes, such as rotting fruit and burning wood, are affected by temperature. More heat and energy causes a faster chemical change.
Wood burning and fruit rotting creates new substances through a chemical change that is affected by sound energy.
Rotting fruit and burning wood is a chemical change that occurs because there is a decrease in temperature. Less heat causes a faster chemical change.
When a chemical change occurs, the new substance that is created has properties similar to the original substance.

The MSDS for propane gives it a health rating of 1, a flammability rating of 4, and a reactivity rating of 0. According to the MSDS, which best describes propane? highly corrosive highly toxic highly flammable highly reactive.
Propane has MSDS rating for flammability 4, thus the compound has been highly flammable. Thus, option C is correct.
The MSDS has been the Material Safety Data Sheet . It has been given for the compounds hazardous levels. The compounds have been checked on various parameters and ranked on the scale of 0 to 4.
The compounds being less value in the parameter has 0 value, while 4 has been the maximum value.
The MSDS rating for propane has been able to deliver the compound to be:
Health rating: 1The compound has been less positive towards the health.
Flammability: 4The compound has been highly flammable.
Reactivity: 0The compound has been least reactive.
Since, propane has MSDS rating 4 for flammability, the compound has been highly flammable. Thus, option C is correct.

do Plants and animals create energy the same way?
Answer:
Yes
Step By Step Explanation:
Plants extract energy from food molecules the same way animals do — by cellular respiration.
Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called "photosynthesis". ... Plants get their energy in form of starch whereas animals get it in form of glycogen. Animals get their energy from the food they eat. Animals depend on other living things for food. Some animals eat plants while others eat other animals. This passing of energy from the sun to plants to animals to other animals is called a food chain.
Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP.
