Which number on the diagram is labeling the large intestine?
a. 4
b. 5
c. 2
d. 3

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we're finding the new volume

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

We have

[tex]V_2 = \frac{3.5 \times 6}{2.4} = \frac{21}{2.4} \\ = 8.75[/tex]

We have the final answer as

A positive test will result in the lime water turning milky. Lime water turns milky as the Calcium hydroxide (chemical name for limewater) reacts with carbon dioxide to form Calcium Carbonate which is insoluble in water and thus forms a milky white precipitate.

B, wax melting

Explanation:

When wax melts, the form of matter is the only thing that changes. Wax in this case goes from a solid to a liquid, and this process can be reversed when it cools. Hence labeling it a physical change instead.

Answer:

% m/m = 16.6%

% m/v = 20%

3.42 m (molalidad)

3.42 M (molaridad)

Fraccion molar del soluto = 0.06

Fraccion molar del solvente = 0.94

Explanation:

Nuestra solución está compuesta por:

Soluto: 50 g de sal

Solvente: 250 mL de agua.

%m/m %m/v molalidad, molaridad, fracción molar del soluto y del solvente son distintas formas de definir la concentración:

% m/m son los gramos de soluto cada 100 g de solución.

No sabemos la masa de solución pero con la densidad del agua (solvente), sabemos que los 250 mL contienen 250 gramos de solvente. (Densidad del agua 1g/mL). En conclusión, la masa de solución es 50 g + 250g = 300

% m/m = (50g /300g ) . 100 = 16.6%

Vamos a definir que el volumen de la solución es igual al del solvente: 250 mL.

% m/v = la masa de soluto, cada 100 mL de solución

= (50 /250) . 100 = 20 %

Molalidad, son los moles de soluto por cada kg de solvente.

Convertimos gramos a kg → 250 g . 1kg /1000g = 0.25kg

Convertimos la masa de soluto (sal) a moles.

NaCl → 50 g . 1mol/ 58.45g = 0.855 moles

m = 0.855 /0.25 → 3.42 m (molalidad)

Molaridad son los moles de soluto por cada L de solución.

Convertimos mL a L → 250 mL . 1kg / 1000mL = 0.25 L

sabiendo que los moles de soluto son 0.855, en este caso la molaridad es igual a la molalidad ( 3.42 M)

Para calcular la fracción molar, necesitamos moles de soluto y de solvente.

Ya contamos con los moles de soluto.

Moles de solvente: 250 g . 1mol /18g = 13.89 mol

Moles totales = 0.855 + 13.89 = 14.745

Fracion molar del soluto: (0.855/ 14.745) = 0.06

Fraccion molar del solvente: (13.89 / 14.745) = 0.94

Explanation:

Answer:

Because it can cause health problems or injuries to our sense organs.

Explanation:

Chemicals in the laboratory are made up of different constituents, which may be dangerous or injurious to health. This is the reason why safety measures or precautions have to be taken when working in the laboratory. One of those safety measures is that "one should never use taste, touch, or smell to identify an unknown chemical".

This is so because a chemical that is unknown amounts to the fact that what such chemical contains is unknown, hence, the chemical might have the ability to cause harm or injuries to the sense organ. For example, a conc. acid that is tasted will burn the tongue etc.

30.6 g of ammonia are produced.

Answer:

given

mass of hydrogen =5.4 gram

mass of NH3=?

we have

3 moles of H2=2 moles of NH3

3×2g of H2=2×(14+3) g of NH3

6 g of H2=34 g of NH3

5.4 g of H2=34×5.4/6=30.6 g of NH3

30.6 g of ammonia produced by the reaction of 5.4 g of hydrogen with an excess of nitrogen.

The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.

A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.

Given,

Mass of Hydrogen = 5.4 g

Moles of hydrogen = mass ÷ molar mass

                            = 5.4 ÷ 2 = 2.7 moles

From the reaction, 3 moles of hydrogen produce 2 moles of ammonia

So, 1 mole of hydrogen will produce 2 ÷ 3 moles of ammonia

Thus, 2.7 moles will give ( 2÷3) × 2.7

               = 1.8 moles of ammonia

Mass of ammonia = 1.8 × 17

                 = 30.6 g

Therefore, 30.6 g of ammonia produced by the reaction of 5.4 g of hydrogen with an excess of nitrogen.

Answer: Although the best-known cause of a mass extinction is the asteroid impact that killed off the non-avian dinosaurs, in fact, volcanic activity seems to have wreaked much more havoc on Earth's biota. Volcanic activity is implicated in at least four mass extinctions, while an asteroid is a suspect in just one. Examples, of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.
