To name compounds, usually, they are a combination of a metal and a nonmetal, between nonmetals and between metals. The two elements here are ammonium (NH₄) and sulfur (S). These are both nonmetals. When you name the compound, start by ammonium, followed by sulfur plus a suffix of -ide. The compound is ammonium sulfide.

<u>Answer:</u> The name of the given compound is ammonium sulfide.

<u>Explanation:</u>

We are given a chemical compound having chemical formula of (NH_4)_2S. This is formed by the combination of ammonium (NH_4^+) ions and sulfur S^{2-} ions.

The given compound is an ionic compound because complete transfer of electrons takes place from one atom to another atom.

The nomenclature of ionic compounds is given by:

  • Positive ion is written first.
  • The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
  • In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.

Hence, the name of the given compound is ammonium sulfide.

The maximum kinetic energy of a box sliding from the top of a ramp to the bottom is A) at the top. B) at the bottom. C) at the e
Readme [11.4K]

Kinetic energy of an object can be expressed in terms of its mass m and velocity v as:

KE = 1/2 * m* v²

Thus higher the velocity, greater will be the Kinetic energy. Now, as the box moves along a ramp from top to bottom, its velocity increases and so does the KE. Hence, kinetic energy is maximum at the bottom

Ans B) at the bottom

The four fundamental forces are arranged in the increasing order of their relative strength.
natali 33 [55]

Answer:

The correct answer is - both act only between non-atomic particles.

Explanation:

The decreasing order of their relative strength is - the strong force, electromagnetism, weak force, gravity.

so, A would be here = gravity

B would be  = weak force

C  would be = strong force

The weak and strong forces both are fundamental forces that act on sub-atomic particles only such as quarks.

Calculate the speed of sound wave with a frequency of 20hz and a wave length of 3.00m
Marta_Voda [28]
Wavelength is the distance of one frequency wave peak to the other and is most commonly associated with the electromagnetic spectrum.[1] Calculating wavelength is dependent upon the information you are given. If you know the speed and frequency of the wave, you can use the basic formula for wavelength. If you want to determine the wavelength of light given the specific energy of a photon, you would use the energy equation. Calculating wavelength is easy as long as you know the correct equation.
