Difference between Electron Proton and Neutron?

Answers

Answer 1

Answer:

protons-positively charged

neutrons-uncharged

electrons- negatively charged

Answer 2

The differences are protons give out a positive charge neutrons are neutral and electrons give out negative charge.

Another one is the fact they are located on specific separate parts of an atom and each atoms consists a different amount each charge hope this helped :)

What happens when a wire passes through a magnetic field?

Answers

Answer:

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving).

Explanation:

Answer:

When a conductor moves through a magnetic field, there will be a generated motional emf. This is one example of Faraday's Law and it arises from the magnetic force. The voltage generated in a length of wire, presuming that the entire length moves through a uniform field, is given below.

.What does the changing the Aperture do when taking a photo? *
4.What effect can you get from using a slow shutter speed? *
5.What effect can you create by using a quick shutter speed?

Answers

Answer:

Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.

The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

17 Which changes decrease the rate of reaction between magnesium and air?
1.heating the magnesium to a higher temperature
2.using a higher proportion of oxygen in the air
3.using magnesium ribbon instead of powdered magnesium
A 1, 2 and 3
B 1 only
C 2 only
D 3 only​

Answers

Im pretty sure the answer is d

Using magnesium ribbon instead of powdered magnesium decrease the rate of reaction between magnesium and air.

What is rate of reaction?

Rate of reaction tells about the duration of the completion of the reaction.

Rate of any reaction is directly proportional to the concentration and surface area of the reactant, temperature, catalyst, no. of collision, activation energy, etc.

So, if we magnesium in the ribbon instead of powdered magnesium the surface area of the reactant side decreases which results in the decrease of the rate of reaction.

Hence, option (D) is correct i.e. rate of reaction decreases on using magnesium ribbon instead of powdered magnesium.

What is convex lens?

Convex lens is a type of lens, in which one at least one side is curved outside. These lenses have the ability to focus an outside light beam to a spot on the opposite side by converging it.

The focal length of the convex lens is the distance from the lens's center to this point, which is known as the focus. On the other hand, a plano-convex lens has one surface that is flat and the other that is convex.

Convex lenses cause light from an item to bend, creating an upright, smaller, and inverted picture of the original object. As a result, the candle in this instance will be smaller, upside down, and actual.

Answers

Answer:

2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of lithium phosphate and magnesium nitrate are mixed.

2 Li₃PO₄(aq) + 3 Mg(NO₃)₂(aq) ⇒ 6 LiNO₃(aq) + Mg₃(PO₄)₂(s)

The complete ionic equation includes all the ions and insoluble species.

6 Li⁺(aq) + 2 PO₄³⁻(aq) + 3 Mg²⁺(aq) + 6 NO₃⁻(aq) ⇒ 6 Li⁺(aq) + 6 NO₃⁻(aq) + Mg₃(PO₄)₂(s)

The net ionic equation includes only the ions that participate in the reaction and insoluble species.

A 4.03 g sample of nitrogen gas has a volume of 921 milliliters at a pressure of 3.19 atm. The temperature of the N2 gas sample is:_____.

Answers

Answer:

249 K

Explanation:

Step 1: Given data

Mass of nitrogen (m): 4.03 gVolume of the gas (V): 921 mL = 0.921 LPressure of the gas (P): 3.19 atm

Step 2: Calculate the moles corresponding to 4.03 g of nitrogen

The molar mass of N₂ is 28.01 g/mol.

4.03 g × 1 mol/28.01 g = 0.144 mol

Step 3: Calculate the temperature of the gas sample

We will use the ideal gas equation.

P × V = n × R × T

T = P × V / n × R

T = 3.19 atm × 0.921 L / 0.144 mol × 0.0821 atm.L/mol.K

T = 249 K

How much water would need to be added to 1092 mL of a 54.7 M NaCl solution to make a 0.25 M solution?

Answers

Answer:

237.8L of water would need to be added.

Explanation:

The first thing to do is to identify that the equation to be used is M1V1=M2V2. (This equation works because it turns everything into moles which can then be compared).

Then figure out what information you have and what is being found. In this case:

M1 = 54.7 M

V1 = 1092 mL = 1.092 L

M2 = 0.25 M

V2 = unknown

Then solve the equation for whatever you are trying to find.

M1V1=M2V2

V2=M1V1/M2

Now you need to plug everything in.

V2=(54.7M*1.091L)/0.25M

V2=238.93L

That means that the solution needs a volume of 238.7L to gain a molarity of 0.25M but the starting solution already had a volume of 1.092 L meaning that to find the amount of solvent that needs to be added you just subtract the starting volume by the volume that the solution needs to be.

238.93L - 1.091L = 237.8L

Therefore the answer is that 237.8L needs to be added to a 1.092L 54.7M NaCl solution to make the concentration 0.25M.

Group of answer choices

Answers

Answer:

ΔH3 = -110.5 kJ.

Explanation:

Hello!

In this case, by using the Hess Law, we can manipulate the given equation to obtain the combustion of C to CO as shown below:

C(s) + 1/2O2(g) --> CO(g)

Thus, by letting the first reaction to be unchanged:

C(s) + O2(g)--> CO2 (g) ; ΔH1 = -393.5 kJ

And the second one inverted:

CO2(g) --> CO(g) + 1/2O2(g) ; ΔH2= 283.0kJ

If we add them, we obtain:

C(s) + O2(g) + CO2(g) --> CO(g) + CO2 (g) + 1/2O2(g)

Whereas CO2 can be cancelled out and O2 subtracted:

C(s) + 1/2O2(g)  --> CO(g)

Therefore, the required enthalpy of reaction is:

ΔH3 = -393.5 kJ + 283.0kJ

ΔH3 = -110.5 kJ

When [H+] = 4.0 × 10–9 M in water at 25°C, then
Kw =1.0×10–14.
b. pOH = 7.
c. [H3O+] = [OH–].
d. pH= 7
e. A-D are all correct

Answers

Answer:

a. Kw = 1.0 × 10⁻¹⁴

Explanation:

a. Let's consider the self-ionization of water.

2 H₂O(l) ⇄ H₃O⁺(aq) + OH⁻

The ion-product of water (Kw) at 25 °C is:

Kw = [H₃O⁺][OH⁻] = 1.0 × 10⁻¹⁴

c. Considering [H⁺] = [H₃O⁺] = 4.0 × 10⁻⁹ M, the concentration of OH⁻ is:

[OH⁻] = 1.0 × 10⁻¹⁴/[H₃O⁺] = 2.5 × 10⁻⁶ M

b. We can calculate the pOH using the following expression.

pOH = -log [OH⁻] = -log 2.5 × 10⁻⁶ = 5.6

d. We can calculate the pH using the following expression.

pH = -log [H⁺] = -log 4.0 × 10⁻⁹ = 8.4

When [H+] = 4.0 × 10–9 M in water at 25°C, then the [tex]Kw =1.0\times 10^-^1^4.[/tex]

What is dissociation constant?

Kw is the dissociation constant or ionization constant of water.

The self-ionization of water will be

[tex]\rm 2 H_2O(l) = H_3O^+(aq) + OH^-[/tex]

The dissociation constant of the water at 25°C will be

[tex]\rm Kw = [H_3O^+][OH^-] = 1.0 \times 10^-^1^4[/tex]

Thus, the correct option is a. [tex]Kw =1.0\times 10^-^1^4.[/tex]

Answer:

¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

Explanation:

To know which equation is unbalanced, we shall compare the mass number and atomic number of the reactant and product together. This is illustrated below:

¹²¹₅₀Sn —> ⁰₋₁β + ¹²¹₅₁Sb

121 = 0 + 121

121 = 121

50 = –1 + 51

50 = 51

Thus the above equation is balanced

¹⁹⁰₇₈Pt —> ¹⁸⁶₇₆Os + ⁴₂α

190 = 186 + 4

190 = 190

78 = 76 + 2

78 = 78

Thus, the above equation is balanced

¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

10 = 10 + 0

10 = 10

4 = 3 + (–1)

4 = 3 – 1

4 = 2

Thus, the above equation is unbalanced.

²³⁸₉₂U —> ⁴₂α + ²³⁴₉₀Th

238 = 4 + 234

238 = 238

92 = 2 + 90

92 = 92

Thus, the above equation is balanced.

From the illustrations made above, only ¹⁰₄Be —> ¹⁰₃Li + ⁰₋₁β

Is unbalanced.
