Compared to an electron, which particle has a charge that is equal in magnitude but opposite in sign?

1 answer:

8 0

I think the correct answer is proton since protons have a charge of +1 while electrons have a charge of -1. However, since beta particles are used to name a type of nuclear decay and can refer to either a positron or electron depending on the circumstances, your teacher might want you to put beta particle since positrons are basically electrons but that have a positive charge.
I hope this helps. Let me know if anything is unclear.

What are some uses of radioactive dating? <br> HELPP PLEASEEEE!!!

Irina-Kira [14]

Answer:

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over 300 naturally-occurring isotopes are known.

The absorbance of a garbanzo bean solution that had been diluted by a factor of three was 0.528. what was the concentration of t

Serjik [45]

The Beer-Lambert law states that A = E*c*l where A is absorbance, E is the molar absorbance coeffecient, c is concentration and l is path length. Therefore the absorbance is directly proportional to concentration, and by increasing the concentration by a factor of 3, absorbance will increase by a factor of 3 giving A = 1.584

a) Provide equation of K of this reaction, use symbol " ^ " for exponents. That means 1000 = 10^3 and 1/100 is 10^(-2). b) How m

stealth61 [152]

Answer and Explanation:

a. The equation of K of this reaction is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

$K = \frac{(D)^5 (E)^7 (F)}{(A)^3 (B)^5 (C)^4}$

b. The moles of compound F is shown below:-

3 A + 5 B + 4 C↔5 D + 7 E + F

2 moles

Now, the mole of produced is

$= \frac{1}{4} \times \ moles\ of\ c$

Now, we will the value of c by using the above equation

$= \frac{1}{4} \times 2$

After solving the above equation we will get

0.5 moles

Which of the following are density labels?

shtirl [24]

Answer:

Kg/L , g/mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
