Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present.

Answer:

Hope this helps :)

Explanation:

1. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.

2. Matter is everything around you. Atoms and compounds are all made of very small parts of matter.

3. Solid, liquid and, gas

4. False

5. Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon.

6. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.

La etiqueta de una bebida transparente con un ligero toque anaranjado indica que contiene aga con un 15 porciento de zumo de nar
Brilliant_brown [7]

<u>Respuesta:</u>

16 gramos de vitamina C y 8 gramos de colorantes.

Explanation:

Debemos multiplicar el porcentaje de cada componente por la cantidad total (100 %) de zumo.

800 g de zumo = 100%

- Tenemos un 2 porciento (2 en 100 o 2/100) de vitamina C. Por lo tanto, la cantidad en gramos de vitamina C es:

2/100 x 800 g = 16 g

- Tenemos un 1 porciento de colorantes en el zumo (1/100). Por lo tanto, la cantidad en gramos de colorantes es:

1/100 x 800 g = 8 g

I have a 5 liter container of oxygen (O 2 ) gas at 2.0 atm and 25 0 C, what mass of gas is inside this
Thepotemich [5.8K]

Answer:

m=13.1gO_2

Explanation:

Hello,

In this case, by using the ideal gas equation, we first compute the moles of oxygen at the given volume, pressure and temperature:

PV=nRT\\\\n=\frac{PV}{RT}=\frac{2.0atm*5L}{0.082\frac{atm*L}{mol*K}(25+273.15)K}  =0.41mol

Then, since molar mass of gaseous oxygen is 32 g/mol, we compute the contained mass in grams as shown below:

m=0.41mol*\frac{32g}{1mol}\\\\m=13.1gO_2

Best regards.

How many liters of oxygen are needed to react completely with 81.0 g of aluminum at STP?
Gelneren [198K]

Answer:

Volume O₂ at STP = 50.4 Liters

Explanation:

4Al(s) + 3O₂(g) => 2Al₂O₃(s) at STP conditions

81g Al(s) = 81g/27g/mole = 3mole Al

moles O₂ consumed = 4/3(3)moles O₂ = 2.25 moles O₂ consumed

Volume O₂ at STP = 2.25moles x 22.4L/mole = 50.4 Liters O₂
