Fe(s) + CuSO4(aq) -> Cu(s) + FeSO4(aq) is the answer if you get it in advance...
Answer:
4.44 dm³ of SO₂
Solution:
The balance chemical equation is as follow,
CS₂ + 3 O₂ → CO₂ + 2 SO₂
According to equation,
22.4 dm³ (1 mole) CS₂ produces = 44.8 dm³ (2 mole) of SO₂
So,
2.22 dm³ CS₂ will produce = X dm³ of SO₂
Solving for X,
X = (2.22 dm³ × 44.8 dm³) ÷ 22.4 dm³
X = 4.44 dm³ of SO₂
Hello. You have not presented the image that presents the two elements mentioned in the question. This makes it impossible for your question to be answered. However, I will try to help you as best I can.
To say whether the compounds obey the law of multiple proportions, you should observe whether one of the elements, formed from the compounds, maintains a fixed mass, while the other element presents the mass in a varied amount of small, whole numbers, spread across the formed compounds .
This is because the law of multiple proportions states that an element must have a fixed mass when reacting with another element to create compounds. This reaction will allow this element to keep the mass fixed, while the other element will generate different compounds, where each one presents a part of the mass of the forming element, in small and whole numbers.
2. This question has two parts. First, answer
Part A. Then, answer Part B. Part A
In Passage 2, what theme is suggested by Graham’s situation?
D People will do whatever is necessary to keep what is important to them.
Part B
Which quotation helps develop the theme in Part A?
D “Graham turned to the old man and asked, ‘How are we going to find it?’” (paragraph 25)
Part A
Option D: This answer is correct. The man agrees to the risky proposition to search for buried treasure since it seems to be the only way for him to keep his family's property.
Part B
Option D: This answer is correct. This quotation shows that Graham is considering the man's proposition to look for buried treasure in the hopes of keeping his family's property
