how many grams of S are in 665 g of SO2
Answer: 111g S
Explanation:
SO2 you have = 665 g
SO2 molar mass = 64.066 g/mol
S molar mass = 32.065 g/mol
[tex]665g SO2*\frac{1 molSO2}{64.066gSO2} *\frac{1molS}{3molSO2} * \frac{32.065gS}{1molS} = 110.944... ~ 111gS[/tex]
There are 332.5 grams of S (sulfur) in 665 g of SO2 ( sulfur dioxide).
From the information given:
The atomic mass of sulfur = 32 g/mol
The atomic mass of oxygen = 16 g/mol
∴
The molar mass for SO2 = 32 + (16 × 2) g/molThe molar mass for SO2 = 64 g/molSince there are 665g of SO2;
If 1 mole of SO2 contains 1 mole of S
It implies that:
(1 × 64)g of SO2 will contain (1 × 32) g of S;
∴
665 g of SO2 will contain :
[tex]\mathbf{= \Big ( \dfrac{1 \times 32}{1 \times 64} \times 665 \Big )}[/tex]
= [tex]\mathbf{\Big 332.5 \ grams \ of \ S \Big}[/tex]
Therefore, we can conclude that there are 332.5 grams of S present in 665 g of SO2.

A hydrated sample weighing 20.0 g is heated in a crucible at 250°C. After cooling the sample now has a weight of 16.5 g.
What is the weight of the water lost from the sample? ______________
If the % water in the sample = g waterg of original sample x 100, what is the % water in the sample?
Given parameters:
Weight of hydrated sample = 20g
Temperature = 250°C
Weight after cooling = 16.5g
Unknown:
Weight of water lost from the sample = ?

Gravity would cause the rain falling in which two locations to drain into the area B
Answer:
4 and 3
because i guessed
Gravity would cause the rain falling in (3) and (4) locations to drain into area B. thus these locations are most near to basin area B.
How does gravity affect rainfall?Through watersheds, gravity forces water to flow down on the land and precipitation to fall from clouds. The constant circulation of water between these reservoirs is powered by gravity and solar energy. The water turns from a liquid to a gas as it becomes hotter.
Rainfall can be significantly influenced by mountains. Air must rise to overcome this obstruction once it reaches the mountains. A mountain's windward side causes the air to cool and lose volume as it ascends. As a result, humidity rises, and precipitation and orographic clouds may form.
The image is attached below.
Therefore, these locations are most near basin area B.

In the 17th century, British biologist Robert Hooke discovered the cell. A little more than a century later, French botanist René Henri Dutrochet concluded that all living things arise from cells, and all cells are derived from other cells. Dutrochet's proposal indicates that —
A
cells are the highest level of organization in a living organism.
B
cells are not a level of organization in a living organism.
C
cells alternate between being the highest and lowest level of organization in a living organism.
D
cells are the lowest level of organization in a living organism.
Answer: A
Explanation:
Robert Hooke discovered the cell. Cells are the highest level of organization in a living organism. so, option A is correct.
What is cell ?Cell is the smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. It is a small unit of organism containing nucleus.
The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates how substances enter and exit the cell.
After using a very early microscope to examine a piece of cork, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber." It is also claimed that he believed the rectangular chambers to resemble some monastic cells.
Thus, option A is correct.

If you start using 10.0 grams of NaHCO3 and excess of acetic acid, how many moles of CO2 can be formed? How many grams of CO2 can be formed?
Answer:
[tex]n_{CO_2}=0.119molCO_2[/tex]
[tex]m_{CO_2}=5.24gCO_2[/tex]
Explanation:
Hello.
In this case, since the chemical reaction:
[tex]NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2O+CO_2[/tex]
And 10.0 grams of sodium bicarbonate (molar mass = 84 g/mol) are reacting in a 1:1 mole ratio with the yielded carbon dioxide, those moles and grams turn out:
[tex]n_{CO_2}=10.0gNaHCO_3*\frac{1molNaHCO_3}{84gNaHCO_3} *\frac{1molCO_2}{1molNaHCO_3} =0.119molCO_2[/tex]
And the mass by considering the molar mass of carbon dioxide to be 44 g/mol:
[tex]m_{CO_2}=0.119molCO_2*\frac{44gCO_2}{1molCO_2} \\\\m_{CO_2}=5.24gCO_2[/tex]
Best regards.
If you start using 10.0 grams of sodium bicarbonate and excess of acetic acid, you can obtain 0.119 moles of CO₂ (5.24 g).
Let's consider the following neutralization reaction.
NaHCO₃ + CH₃COOH ⇒ CH₃COONa + H₂O + CO₂
First, we will convert 10.0 g of NaHCO₃ to moles using its molar mass (84.01 g/mol).
[tex]10.0 g \times \frac{1mol}{84.01g} = 0.119mol[/tex]
The molar ratio of NaHCO₃ to CO₂ is 1:1. The moles of CO₂ formed from 0.119 moles of NaHCO₃ are:
[tex]0.119 mol NaHCO_3 \times \frac{1molCO_2}{1molNaHCO_3} = 0.119 moles CO_2[/tex]
Finally, we will convert 0.119 moles of CO₂ to grams using its molar mass (44.01 g/mol).
[tex]0.119 mol \times \frac{44.01g}{mol} = 5.24 g[/tex]
If you start using 10.0 grams of sodium bicarbonate and excess of acetic acid, you can obtain 0.119 moles of CO₂ (5.24 g).
