Answer: The pressure will be 411 GH.

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=570\\T_1=2.33\\P_2=?\\T_2=1.68

Putting values in above equation, we get:

\frac{570}{2.33}=\frac{P_2}{1.68}\\\\P_2=411

Thus the pressure will be 411 GH.

You have 1.20 x 10 24 molecules of H2O. What is the mass of this sample?
goblinko [34]

Answer:

35.86~g~H_2O

Explanation:

In this case, we have to remember that relationship between the <u>avogadro's number</u> and the "mol" concept:

1~mol=6.023x10^2^3~molcules

With this in mind, we can do the <u>first conversion</u>:

1.20x10^2^4~molecules~of~H_2O\frac{1~mol_H_2O}{6.023x10^2^3~molcules~of~H_2O}=1.99~mol_H_2O

Now, if we calculate the molar mass of H_2O. <u>The atomic mass of O is 16 g/mol and the atomic mass of H is 1 g/mol</u>, so:

(16*1)+(1*2)= 18 g/mol

In other words, 1~mol~H_2O=~18~g~H_2O, so:

1.99~mol_H_2O\frac{18~g~H_2O}{1~mol~H_2O}=35.86~g~H_2O

I hope it helps!

For a chemical change to happen what must atoms be
LiRa [457]

Answer:

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Que relación tiene el metabolismo celular con el mantenimiento de los seres vivos
Dmitry [639]
El metabolismo es un proceso por el cual los seres vivos ganan masa y energía que ofrece el medio en el que viven y sirve para el mantenimiento, crecimiento y reproducción de estos.

Si tomamos en cuenta la clasificación de los seres vivos tenemos:

- Autótrofos: Crean su propio alimento por medio del sol o la tierra y no de otros seres vivos (plantas, vegetales y algas).

- Heterótrofos: Generan su propio alimento y dependen de los autótrofos o de otros heterótrofos para su alimentación (animales y algunas bacterias).

El metabolismo se divide en dos procesos conjugados, el catabolismo y el anabolismo. Estos procesos dependen el uno del otro.

Las reacciones catabólicas liberan energía, mientras que las reacciones anabólicas, utilizan esa energía liberada para recomponer enlaces químicos y construir componentes de las células como las proteínas y los ácidos nucleicos..

De esta manera se relacionan ambos
