What volume of 0.100 M AgNO3 is
needed to react completely with
45.0 mL of 0.230 M Na2S?
2AgNO3 + Na2S → Ag2S + 2NaNO3
[?] mL AgNO3

Answers

Answer:

448mL AgNO3

Explanation:

M x V

n = 0.230 x .045 = 0.01

2AgNO3 + Na2S --> Ag2S+2NaNO3

1 mol Ag2S --> 2 moles AgNO3

.01 mol Ag2S --> ? moles AgNO3

.01x2/1=.02 moles AgNO3

Moles to L conversion is multiplying by 22.4L so we do .02 x 22.4=0.448L

Then we convert to mL so we multiply by 1000 (1000 x 0.448)

448mL AgNO3

There you go friend, good luck with chemistry :)

The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: CaCO,CaO+CO, He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer.​

Answers

Answer:

According to conservation of matter, there should be equal amounts of all elements on both the reactant and product side.

Reactant:

1 Ca

1 C

1 O

Product:

1 Ca

1 C

3 O

Therefore, your friend is right because the law of conservation of matter is not followed in this chemical equation.

Give reason. When the tip of a plant is cut, it does not grow tall.

Answers

11) What volume will 0.75 mol of Oxygen gas (O2) occupy at 298 K and a pressure of 52.7 kPa?

Answers

Answer:

Volume = 35.3L

Explanation:

Use Ideal Gas Law (PV=nRT) and isolate for V (volume) by dividing both sides by P (pressure). You will then get the eqaution listed below and you can solve by using the method I used below.

V = nRT/P

V = (0.75kPa)(8.314)(298K)/(52.7kPa)

V = 1858.179/52.7

V = 35.3L

dubnium chloride chemical formula

Answers

Answer:

Db

Dubnium/Symbol

Explanation:

please mark my answer in brainlist plz

Answer:

DbCl5

Explanation

Dubnium has 2 electron in 7s orbital and 3 electron in 6d orbital. Because Dubnium is synthetically produced with atomic number of 105, it is highly radioactive and quickly decay. Like other transition, it can have different oxidation state and it is assumed that dubnium have +3,+4,+5 oxidation state number(that most likely involves electron from 6d orbital). Hence chloride ions with -1 oxidation number would react to form Dubnium Chloride as DbCl3, DbCl4, and DbCl5. Now it is highly unlikely these compounds can really be formed. However if you read nature chemistry article https://www.nature.com/articles/nchem.2610, there is mention that DbCl5, DbBr5, and DbOCl3 may be expected to form.

A. KCL
B. ICL
C. PCL
D. HCL

I think it’s A and D but if it’s not both can you please explain why it’s one and not the other?

Answers

Answer:

Yes Both A) KCL and D) HCL are correct...

Answer:

It's only A

Explanation:

Potassium (K) is a metal and Chlorine (Cl) is a nonmetal, and ionic compounds are formed between metals and nonmetals. So KCl forms ionic bonds.

Hydrogen (H) and Chlorine (Cl) are both nonmetals, and only covalent bonds form between nonmetals. (Only exception is when its an acid, then it's ionic)

Also, the question indicated which "pair" and not "pairs" meaning that there is only one answer, and I'm more likely to go with A rather than D.

Major cities all over the world are changing color. The tall gray buildings that make up the landscape of urban environments are becoming greener. They aren't getting a fresh coat of paint. Instead, their roofs are being covered in grass and small shrubbery. Many rooftops are beginning to look like nature parks. This change isn't just for fun. It is an attempt to add plants that can clean city air, absorb waste water, and generally add beauty to the city environment.Green roofs started in Europe and are now gaining a strong foothold in the United States. They are a way to add a little nature to the city environment. People plant vegetable gardens, flowers, and decorative grasses on their rooftops. One green roof in New York City is built on top of a processing and distribution facility. It is the largest green roof in the country. It has survived snow and rain, given employees a beautiful place for a lunch break, and helped clean the city air.It is more expensive to build a green roof than it is to lay asphalt or shingles. The basic green roof requires a frame and a waterproof membrane. It also requires gravel for drainage. Special material needs to be laid to retain moisture. Of course, soil for planting and a barrier that prevents roots from penetrating the building are also necessary materials for a green roof. Despite the extra cost, the trend is growing.The city of Chicago now has more green roofs than any other U.S. city. There are 7 million square feet of green roofs planted across the city. Toronto, Canada, is the first city in the western hemisphere to mandate green roofs on all new tall buildings. Green roofs are beneficial to the environment and the cities that build them. A recent study in Toronto suggested that if 75 percent of the flat roofs were greened, the city could save $37 million a year on storm water management and energy bills. If this is true, we may begin to see more and more green added to cities around the world.Why does the author include the point that there are 7 million square feet of green roofs planted across the city of Chicago?A. To paint a picture of what the green roofs in Chicago look like.B. To exaggerate how many green roofs there are in the city.C. To show that Chicago has not accepted the green roof trend.D. To prove that Chicago has the most green roofs in the United States. ayo i need some help pleaseeeeee!!!!i need a two paragraphs about this story called the first free summer, i also need a story idea to read What is 5 rounded to the nearest whole number, explain why HELP.
