Answer:
### What is Volume?

The **volume **of 45.6g of **silver **if the density of silver is 10.5g/mL is **4.342 ml. **The correct option is** A.**

**Volume **is the space occupied by a three-dimensional object. The volume of any object can be calculated by dividing the **mass **by its **density**. It is a scalar quantity. It is the total weight is that object.

**Silver **is an element in the periodic table. It is non-metal, and it is used in making ornaments and in **medicines**. The volume of the solver is calculated, and the mass and density are given.

The mass of silver is given, 45.6g

The density of the element is 10.5g/mL

Putting the value in the equation

The **density **and the **mass **would be divided.

**Volume **= 45.6g / 10.5 = 4.342

Thus, the **volume **of silver is** 4.342 ml.** The correct option is **A.**

Answer:

**Explanation:**

first you get moles of silver

n=m/M

hence you add no of moles to this equation

c=nv

v=n/c

You have been injured in the laboratory (cut,burn,etc) first you should

**Answer:**

7.97 mol Ar

**Explanation:**

Use Avogadro's number to convert atoms to moles. This number is the number of atoms in one mole. There are 6.022 × 10²³ atoms in one mole.

Divide the number of atoms given by Avogadro's number.

(4.80 × 10²⁴)/(6.022 × 10²³) = 7.97 mol

There are 7.97 moles of argon.

**Explanation:**

Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid. ... Colloidal systems can occur in any of the three key states of matter gas, liquid or solid. However, a colloidal solution usually refers to a liquid concoction.

**Answer:**

Colloidal solutions, or colloidal suspensions, are nothing but a mixture in which the substances are regularly suspended in a fluid.

**Answer:**

34 g

**Explanation:**

Let's consider the following **balanced equation**.

N₂ + 3 H₂ → 2 NH₃

The **theoretical mass ratio of N₂ to H₂** is 28g N₂ : 6g H₂ = 4.6g N₂ : 1g H₂.

The **experimental mass ratio of N₂ to H₂** is 100g N₂ : 6g H₂ = 16.6g N₂ : 1g H₂.

As we can see, hydrogen is the **limiting reactant**.

According to the task, we 6 g of H₂ react completely, **34 g of ammonia are produced**.

**Given:**

Radiation emission in Cs atom = 9,192,632,770 cycles

**To determine:**

The wavelength of the above radiation

**Explanation:**

It is given that :-

1 sec equivalent to 9,192, 631, 770

Now, frequency (ν) = cycles /sec = 9,192, 631, 770/sec

Wavelength of a radiation is given as:

**λ = c/ν**

where c = speed of light = 3*10⁸ m/s

λ = 3*10⁸ ms⁻¹/9,192, 631, 770 s⁻¹ = 0.0326 m

**Ans: Thus the wavelength of this radiation is 0.033 m**

To calculate the wavelength of this radiation if the SI unit of time is the second, which is defined as 9,192,631,770 cycles of radiation associated with a certain emission process in the cesium atom, the wavelength is one cycle of radiation, and therefore the wavelength is 1/9192631770

The given **electronic configuration** 1s²2s²2p⁶3s²3p⁶4s²3d⁸ is the **Nickel** (Ni). Therefore, option (B) is correct.

The** electron configuration **can be explained as electrons being filled in different energy levels of an atom of a particular **element**. In the electron configuration, the number of **electrons** is usually written as a superscript of **atomic subshells**. For example, the electron configuration of **Oxygen** is written as 1s²2s²2p⁴.

The sequence of fully filled **subshells** that correspond to the electronic configuration of a noble gas is denoted by **square brackets**. The **principal quantum number** (n) can be used to evaluate the maximum number of electrons in an electron shell.

The value of 2n² is given the maximum number of electrons. The **atomic****orbitals** at low energy must be filled first occupying an orbital with a higher **energy level**.

The total number of **electrons** filled in the given **electronic****configuration** 1s²2s²2p⁶3s²3p⁶4s²3d⁸ is 28. The atomic number of Nickel is 28 therefore it is the configuration of **Nickel**.
