Chemistry
1 answer:
JulijaS [17]3 years ago
4 0

Answer:

135.027

Explanation:

Take the molar mass (from the periodic table) of Nitrogen (14.007) and Oxygen (15.999)

Add them together: 30.006 (this is 1 mole of NO)

30.006x4.5=135.027g

Calculate the de Broglie wavelength of a body of mass 1 kg moving with a velocity of
skelet666 [1.2K]

Answer:

4.42 × 10⁻³⁷ m

Explanation:

Step 1: Given and required data

  • Mass of the body (m): 1 kg
  • Velocity of the body (v): 1500 m/s
  • Planck's constant (h): 6.63 × 10⁻³⁴ J.s

Step 2: Calculate the de Broglie wavelenght (λ) of the body

We will use de Broglie's equation.

λ = h / m × v

λ = (6.63 × 10⁻³⁴ J.s) / 1 kg × (1500 m/s) = 4.42 × 10⁻³⁷ m

An aqueous solution is found to be 3.64% potassium nitrate by mass, how many grams of solution should I evaporate the water from
Sidana [21]

Answer:

513.74 g of solution

Explanation:

% Mass grams are defined as the <em>grams that are dissolved in salt</em> (in this case, it would be <em>potassium nitrate</em>) <em>dissolved every 100 g of the solution</em>. Having this information, you can calculate the amount of solution that has dissolved 18.7 g of potassium nitrate, which is what we want to obtain.

The relationship is:

3.64 g of potassium nitrate _____ 100 g solution

18.7 g of potassium nitrate _____ X = 513.74 g of solution

Calculation: 18.7g x 100g / 3.64g = 513.74 g of solution

So, <em>I need 513.74 g of solution to get 18.7g of potassium nitrate by evaporating it</em>.

sulfur combines with hydrogen to form hydrogen sulfide H2 S by single covalent bond, while it form with potassium by ionic bond​
Alex

Answer: Ions may be defined as the element that contains either positive or negative charge over them. Two types of ions are cations and anions. The outermost electrons are involved in the formation of ions.

The atomic number of sulfur is 16. Its outermost electronic configuration is K=2, L= 8, M= 6. The sulfur requres two more electrons to complete its orbit and accquire -2 charge.
