none of these

Explanation:

Answer:

temperature and rainfall

Explanation:

Answer:

–132.55 °C

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 30.8 L

Initial temperature (T₁) = –67 °C

Final volume (V₂) = 21.0 L

Final temperature (T₂) =?

Next, we shall convert –67 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T₁) = –67 °C

Initial temperature (T₁) = –67 °C + 273

Initial temperature (T₁) = 206 K

Next, we shall determine the final temperature of the gas. This can be obtained as follow:

Initial volume (V₁) = 30.8 L

Initial temperature (T₁) = 206 K

Final volume (V₂) = 21.0 L

Final temperature (T₂) =?

V₁/T₁ = V₂/T₂

30.8 / 206 = 21 / T₂

Cross multiply

30.8 × T₂ = 206 × 21

30.8 × T₂ = 4326

Divide both side by 30.8

T₂ = 4326 / 30.8

T₂ = 140.45 K

Finally, we shall convert 140.45 K to celsius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T₂ = 140.45 K

T₂ = 140.45 K – 273

T₂ = –132.55 °C

Thus, the new temperature of the gas is –132.55 °C

Answer and Explanation:

Solutions that have a pH of 8 would be considered a Weak Base.

This is because a weak base is a base that, upon dissolution in water, does not dissociate completely.

Solutions/liquids that have a pH higher than a pH of 7 are basic solutions, while solutions/liquids that have a pH lower than a pH of 7 are acidic solutions.

When the pH level is closer to 7, it is weak, and when it is far from 7, like if it is 1 or 12, then it is a strong acid/base.

Answer:

conduction

Explanation:

The answer is Conduction

Answer:

0.147 Hz   because I took the test

The velocity of a wave is the product of its frequency and wavelength. The  velocity of wave with 0.147 Hz and 12.05 m is 1.77 m/s.

The frequency of a wave is the number of wave cycles per unit time. Frequency is the inverse of time period of the wave. It is inversely proportional to the wavelength. Unit of frequency is Hz which is equivalent to s⁻¹.

The wavelength of a wave is the distance between two consecutive crests or troughs. The wavelength λ, and frequency ν of a wave is related to the velocity  v of the wave as follows:

v = νλ

Given that,

frequency = 0.147 Hz

wavelength = 12.05 m

then, velocity = 0.147 Hz × 12.05 m = 1.77 m/s.

Therefore, the velocity of the mechanical wave is 1.77 m/s.

Answer:

froth flotation is a technique commonly used in the mining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity.

Explanation:

Froth floatation method is commonly used to concentrate sulphide ore such as galena (PbS), zinc blende (ZnS) etc. (ii) In this method, the metaalic ore particles which are perferentially wetted by oil can be separated from gangue. (iii) In this method, the crushed ore is suspended in water and mixed with frothing agent such as pine oil, eucalyptus oil etc. (iv) A small quantity of sodium ethyl xanthate which act as a collector is also added. (v) A froth is generated by blowing air through this mixture. (vi) The collector molecules attach to the ore particles and make them water repellent. (vii) As a result, ore parrticles, wetted by the oil, rise to the surface along with the froth. (viii) The froth is skimmed off and dried to recover the concentration ore. (ix) The gangue particles that are preferentially wetted by water settle at the bottom.

Answer:

[tex]2Fe +N_{2} -> 2FeN[/tex]

Explanation:

Iron is Fe, nitrogen is N. Nitrogen is diatomic, which means it occurs as a molecular pair by itself. Iron III nitride has a chemical formula of FeN because nitrogen has a charge of 3-, and iron III tells us the iron has a charge of 3+ so you just need one of each to make the charges balance and the compound neutral.

When iron reacts with nitrogen to form iron(III) nitride, the balanced chemical equation of this reaction is as follows:

2 Fe + N₂ → 2FeN

The term balanced chemical equation is defined as a chemical equation in which mass is conserved and there are equal numbers of atoms of each element on both sides of the equation.

The chemical equation must be balanced in order to obey the law of conservation of mass. When the number of different atoms of elements in the reactants side equals the number of atoms in the products side, the chemical equation is balanced.

Nitrogen is diatomic, that means it occurs as a molecular pair by itself. Iron III nitride has a chemical formula of FeN because nitrogen has a charge of 3-, and iron III tells us the iron has a charge of 3+ .

Thus, iron reacts with nitrogen to form iron(III) nitride.
