What will create a insoluble salt with a potassium ion

Chemistry
1 answer:
navik [9.2K]3 years ago
4 0

Explanation:

1) The dissolution of the salt potassium sulfite:

K₂SO₃(aq) → 2K⁺(aq) + SO₃²⁻(aq).

Potassium has +1 charge because it lost one electron to accomplish stabile electron configuration of noble gas argon.

2) From dissolution reaction: n(K⁺) : n(SO₃²⁻) = 2 : 1.

n(K⁺) = 0.700 mol.

0.700 mol : n(SO₃²⁻) = 2 : 1.

n(SO₃²⁻) = 0.700 mol ÷ 2.

n(SO₃²⁻) = 0.350 mol; amount of sulfite anions.

What is the value of 100 ºC on the Kelvin scale? A. 100 K B. 273 K C. 373 K D. -373 K E. -300 K
insens350 [35]

Answer:

373.15 K

Explanation:

Given data:

Temperature in degree Celsius = 100°C

Temperature in kelvin scale = ?

Solution:

To convert the degree Celsius into kelvin scale we add the given  degree Celsius  into 273.15.

100°C +273.15 =  373.15 K

A He-Ne laser (wavelength λ = 600 nm) shines through a double slit of unknown separation d onto a screen 1.44 m away from the sl
ludmilkaskok [199]

Answer:

1.28 ×10^-4m

Explanation:

Interference is the superimposition of the wavefront. The superimposition causes bright and dark fringes.

The dark fringe is formed when the additional distance traveled is equal to the multiple wavelength integrals.

From the question, the parameters given are; Wavelength of the light,λ= 600nm, Distance of the screen (D) = 1.44m, order of the bright fringe (m) = 4, Distance of the 4 order fringe (y) = 2.7 cm.

Therefore, for the maximum bright fringe;

dy/D=mλ-----------------------------------------------------------------------------------------------------------------------(1)

Therefore, slotting in equation (1);

d×0.027/1.44=4×600×10^-9

d= 1.28×10^-4 m.

Question 7 of 32
sergeinik [125]

Answer:

The battery of a phone contains stores chemical energy. This energy is converted into electrical energy primarily when the phone is turned on. The chemical energy is also converted into light energy, sound energy and heat energy. With the passage of time, the energy will be changed back into the chemical energy when we will charge the phone again.

Look at the graph of reaction rate versus substrate concentration for an enzyme. In which region does the reaction rate remain c
OleMash [197]

Answer:

The correct answer is C.

Explanation:

The reaction speed remains constant in region C. This is because the growth rate decreases, tending to zero. Graphically you can see how the slope of the tangent line approaches the horizontal. The slope of the tangent line represents the rate of reaction speed. It is constant because although the concentration continues to increase, the reaction rate does not vary.

Have a nice day!
