Answer:

Wave A= 20m

Wave B= 30m

Explanation:

The amplitude of a wave is the maximum displacement (or height) from its equillibrum position.

The equilibrium position is at 0 meters for both waves.

Thus, amplitude of wave A= 20m

Amplitude of wave B= 30m

photoshop1234 [79]

Answer: 1.284M NH3

Explanation: (12.23 grams)/(17.0 gramms/mole) = 0.7191 moles

Dissolved in 560.0 ml (=0.5600L)

(0.7191 moles)/(0.560L) = 1.284M (4 sig figs)

The valence electrons of a krypton (Kr) atom in the ground state are located in the

Korvikt [17]

I dont know the answer but i have some explanation for that question.

Since krypton is in the far right row of the periodic table, its outermost shell is full with eight electrons. This is one of the happy elements and has an electron configuration of 2-8-18-8.

Calculate the molarity of a solution<br> made by 1,5kg of K. CO₂ in 850 mL<br> of water.

anastassius [24]

Answer:

17.83M

Explanation:

Given parameters:

Mass of KCO₂ = 1.5kg

Volume of water = 850mL

Unknown:

Molarity of solution = ?

Solution:

Molarity is defined as the number of moles per unit volume. It is the number of moles of solute in a given volume of solution.

Molarity = $\frac{number of moles }{volume}$

Number of moles of solute = $\frac{mass of KCO_{2} }{molar mass}$

Molar mass of KCO₂ = 39 + 12 + 3(16) = 99g/mol

Number of moles = $\frac{1500}{99}$ = 15.15moles

850mL : gives 0.85L

Molarity = $\frac{15.15}{0.85}$ = 17.83M
