how many grams is 3.49 moles NaCl
Answer:
m = 204.16 grams
Explanation:
Given that,
No. of moles, n = 3.49
Molar mass of NaCl, M = 58.5 g/mol
We need to find the mass of 3.49 moles NaCl. We know that,
[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=3.49 \times 58.5\\\\m=204.16\ g[/tex]
So, there are 204.16 grams in 3.49 moles NaCl.

Answer:
1. 7 (a neutral solution)
Answer: 10-7= 0.0000001 moles per liter
2. 5.6 (unpolluted rainwater)
Answer: 10-5.6 = 0.0000025 moles per liter
3. 3.7 (first acid rain sample in North America)
Answer: 10-3.7 = 0.00020 moles per liter
The concentration of H+ in the Hubbard Brook sample is 0.00020/0.0000025, which is 80 times higher than the H+ concentration in unpolluted rainwater.

How are organisms classified as Eukarya different from organisms classified as Archaea and Bacteria?
A)They are all multicellular.
B)They all produce their own food.
C) They all reproduce sexually.
D) They all have membrane-bound nuclei
Answer: D
Explanation: The Eukarya differ from the Archea and Bacteria in that their cells are eukaryotic, meaning they contain a membrane enclosed nucleus and other membrane enclosed organelles.
Eukarya is different from organisms classified as Archaea and Bacteria because Eukarya have membrane-bound nuclei. Therefore, option (D) is correct.
How does the classification of Eukarya differ from Archaea?The type of cell of the organism can be classified into three domains. First is the bacteria which have no nucleus present in cells. Then Archaea have no nucleus in the cells but they have a different cell wall than bacteria. Then Eukarya have a nucleus in them.
The domains of Archaea and Bacteria are both composed entirely of small, single-celled organisms but they also have differences. All are composed of prokaryotic cells, which are nucleus-less cells. T
All the cells in the Eukarya domain contain their genetic material or DNA within the nucleus. Four classes make up the Eukarya domain: Plantae, Fungi, Animalia, and Protista.
Therefore, the domain of the Eukarya is different from organisms classified as Archaea and Bacteria as Eukarya have membrane-bound nuclei.

A 1.00 L volume of gas at 35.0 °C exerts a pressure of 85.5 kPa. What will the pressure
be at 127 °C? Assume constant volume.
Answer:
111.03kPa = P₂
Explanation:
Gay Lussac's Law states that the pressure of a gas is directly proportional to the absolute temperature when volume remains constant.
The equation is:
P₁T₂ = P₂T₁
Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.
P₁ = 85.5kPa
T₂ = 127°C + 273.15 = 400.15K
P₂ = ?
T₁ = 35°C + 273.15 = 308.15K
P₁T₂ = P₂T₁
85.5kPa*400.15K = P₂*308.15K
111.03kPa = P₂Consider the following balanced equation:

Answer:
when population increases the amount of carbon dioxide also increases as population use oxygen and release carbon dioxide
Carbon dioxide is a major greenhouse gas. The increase in the population increases the carbon dioxide amount.
What is the relation between carbon and population?The main product released from the respiratory process of organisms, especially animals is carbon dioxide. The increase in their population will increase this product.
The increased population will increase the demand for the burning of fossil fuel, pollution, and respiration, and hence the product of these activities, carbon dioxide will increase in the atmosphere.
Therefore, the carbon dioxide will increase with an increase in the population.
