How many grams of water are produced when 2.50 mol oxygen reacts with hydrogen?H2 + O2 + H2O
Select one:
a. 45.0 g
b. 22.5 g
c. 90.0 g
O d. 3.6 g
PLEASE HELP

Answer:  grams

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles. and weighs equal to the molecular mass.

To calculate the moles, we use the equation:

1 mole of Americium weighs = 243 g

Thus of Americium weigh=

Thus the mass  mass in grams of a sample of Americium containing six atoms is

The mass (in grams) of the sample of Americium containing six atoms is 2.42×10⁻²¹ grams

How to determine the mass of Americium containing six atoms?

First, we shall obtain the mole of americium that contains six atoms. This is illustrated below:

From Avogadro's hypothesis,

6.022×10²³ atoms = 1 mole of americium

Therefore, we can say that

6 atoms = 6 / 6.022×10²³

= 9.96×10⁻²⁴ mole of americium

Finally, we shall determine the mass (in grams) of the americium. Details below:

• Mole of americium = 255163.41 moles
• Molar mass of americium = 243 g/mol
• Mass of americium = ?

Mass of americium = Mole × molar mass

= 9.96×10⁻²⁴ × 243

= 2.42×10⁻²¹ grams

Answer: Lysosomes

Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

Correct answer=

gold is an element, it has a symbol of An

Hope it helped

Final answer:

Gold is an element, not a compound or a mixture. It is represented on the periodic table by the symbol Au and cannot be broken down into a simpler substance.

Explanation:

Gold is an element, not a compound or a mixture. It's one of the 118 known chemical elements, and it's represented on the periodic table by the symbol Au (from the Latin 'aurum'). As an element, gold consists of only one type of atom and cannot be broken down into a simpler substance. It differs from a compound, which is formed from two or more elements bonded together, and a mixture, where you can physically separate the individual components that make it up.

Two main food-making processes include cooking and fermentation. Cooking involves preparing and combining ingredients to create a dish, such as a pizza, whereas fermentation uses bacteria, yeast or mold to convert sugars to alcohol, gases or organic acids and is a key process in making bread, cheese, and wine.

There are numerous food-making processes, but two primary ones include cooking and fermentation.

For instance, when making pizza, the process involves inputs like ingredients, the efforts of the pizza maker, and tools and materials for cooking and serving. This process involves different stages such as preparing the dough, spreading the sauce, adding toppings, and baking the pizza in an oven.

Another prominent food making process is fermentation, which is highly involved in the production of foods and beverages. It uses bacteria, mold, or yeast to convert sugars to alcohol, gases, or organic acids. A familiar example of this process is alcohol fermentation, which produces ethanol and is used in making bread products and alcoholic beverages.

The pressure inside the flask on heating it is given as 1.21 atm.

Explanation:

As per Guy Lussac's law, the pressure of any concealed volume of gas particles will be directly proportional to the temperature of the container of the gas particles.

So P ∝ T

To convert celsius to kelvin, add 273.15 to the temperature value in celsius

Since, here the initial temperature of the flask is given as 24°C, so in kelvin it will be 297.15 K. Similarly, the final temperature is said to be 104°C which will be equal to 377.15 K. Then the final pressure will be increased as there is increase in temperature. So, the final pressure inside the flask can be obtained as

So, the pressure inside the flask on heating it is given as 1.21 atm.

Final answer:

Using Gay-Lussac's law, the final pressure of the gas in the flask after heating from 24°C to 104°C, under a constant volume, is approximately 1.2 atm.

Explanation:

The pressure inside the flask can be calculated by using Gay-Lussac's law, which states that the pressure of a gas is directly proportional to its absolute temperature, as long as volume is constant. This is formally expressed as P1/T1 = P2/T2, where P is pressure, T is absolute temperature (in Kelvin), and the subscripts refer to initial and final states.

First, convert the Celsius temperatures to Kelvin by adding 273.15 to the Celsius temperature. T1 = 24°C + 273.15 = 297.15 K, and T2 = 104°C + 273.15 = 377.15 K. Next, rearrange the equation to solve for P2: P2 = P1 (T2 / T1).

So, P2 = 0.95 atm * (377.15 K / 297.15 K) ≈ 1.2 atm. Therefore, the pressure inside the glass laboratory flask after heating to 104°C would be approximately 1.2 atm.
