What is the definition of an Arrhenius acid?

Sun-Bleached hair.

You can't exactly pass down piano skills, they have to be taught and also you can't just be born with strong muscles, they also have to develop over time. Height can't exactly be passed down because some parents are tall and their kids come out short. That leaves the only other option to be Sun-Bleached Hair (hair color).

Hope this helps and have a nice day.

Answer:

two oxygen atoms

Answer:

941 K (668°C)

Explanation:

We have the following data:

Initial pressure : P1 = 1.45 atm

Initial temperature: T1 = 52°C + 273 = 325 K

Final pressure: P2 = 4.2 atm

Final temperature: T2 = ?

The relation between pressure and temperature for a gas at constant volume is given by Gay-Lussac's law:

P1/T1 = P2/T2

That means that the pressure is directly proportional to the absolute temperature (in K). So, we calculate T2 from the equation:

T2 = P2 x T1/P1 = 4.2 atm x (325 K/1.45 atm) = 941 K

Therefore, the final temperature would be 941 K (668°C). This is consistent with the law, that states that if the pressure increase, the temperature will be increased.  

Answer:

[tex]14.8\ \text{atm}[/tex]

Explanation:

[tex]C_1[/tex] = Initial concentration = 1.46 g/L

[tex]C_2[/tex] = Final concentration = 2.7 g/L

[tex]P_1[/tex] = Initial pressure = 8 atm

[tex]P_2[/tex] = Final pressure

From Henry's law we have the relation

[tex]\dfrac{C_2}{C_1}=\dfrac{P_2}{P_1}\\\Rightarrow P_2=\dfrac{C_2}{C_1}P_1\\\Rightarrow P_2=\dfrac{2.7}{1.46}\times 8\\\Rightarrow P_2=14.8\ \text{atm}[/tex]

The pressure of a sample of the same gas at the required concentration is [tex]14.8\ \text{atm}[/tex].

Answer: metal

Explanation:

Answer:

The nuclei of most atoms also contain neutrons . The masses of subatomic particles are very tiny. ... Since the nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. Protons and electrons have electrical charges that are equal and opposite.

There are 2 places where charge is located in the atom:

the nucleus contains neutrons (zero charge) and protons (positive charge)

Around the nucleus there are electrons located on electron shields and the charge of electrons is equal to the charge of protons in the nucleus, but have negative sign.

To sum it all up we can say that the charge of protons in the nucleus is reduced by the charge of electrons on the orbits to make the atom electrically neutral.

The type of decay that Am-241 undergoes to become Np-237 is alpha decay. The correct option is a.

Alpha decay is a type of decay or transformation in which a nucleus emits an alpha particle and change into different atomic nuclei. The atomic number reduces by 2 and the mass is reduced by 4.

Am-241 is an isotope of the chemical element americium. It is a radioactive element and its radioactive decay period is 432.2 years. It is used in the testing of machinery.

When the nucleus of Am changes or emits a radioactive particle. It converts into Np-237. The process is called alpha decay. The atomic mass is reduced by four, and the 241 converts into 237, which become neptunium.

Thus, the correct option is a. Alpha decay.

Answer:

The value 9.8 m/s^2 is the average acceleration of a falling object due to the force of gravity on Earth. The letter g represents this value the formula v=gt. With this constant and formula, the speed of an object is calculated at the time t in seconds after it is dropped.

All objects fall at the same rate of speed due to gravity, regardless of their weight. If a small grain of sand and a bowling ball are dropped at the same time, both hit the floor at the same time. The value of g varies by one's location on the planet, ranging from 9.782 m/s^2 in the Panama Canal Zone to 9.832 m/s^2 at the Noth Pole
