Answer:

25 protons, 25 electrons, 30 neutrons. ......... manganese is the identity

Explanation;

x = atomic number -# of protons

The number of neutrons = x + 5

The mass number (sum of protons + neutrons) = 55.

x + (x + 5) = 55

2x + 5 = 55

2x = 50  

x = 25; atomic number 25 = manganese (Mn)

<u>so ;</u>

<u>25 = Protons </u>

<u> 30=Neutrons  </u>

<u>25=Electrons </u>

A person's weight changes as he travels from the earth to space, but his mass remains the same.
alina1380 [7]
When a man travels from earth to space, the mass of the person, defined as the amount energy a matter has remains constant. However, when he moves to space, gravity decreases until such time that there is no gravity that acts on the person. Weight thus changes or decreases until the point of state called weightlessness.

A 1.36 kg hammer at 22 ms what was the force generated by the hammer
podryga [215]
From the information given, the mass of the hammer seems to be 1.36 kg and the velocity by which it is wielded seems to be 22 m/s. The most suitable formula to be used here is : f = m × v where f is force, m is mass and v is velocity. f = m × v → f = 1.36 × 22 → f = 29.92 kg m/s Therefore the force generated by the hammer is 29.92 N ( kg m/s is the same as Newton)

Aqueous solutions of silver nitrate (AgNO3) and iron(III) chloride (FeCl3) are mixed together. Which ion combines with the chlor
garik1379 [7]
Hello there!

The correct answer is Ag⁺.

If we look at the solubility rules, it says that most chlorides are soluble, <u>except</u><em> </em>with Ag⁺, and Pb²⁺.

I hope this helps!

Using this equation, m1v2=m2v2 , calculate the diluted molarity of 100 mL of a 0.5 M solution when 50 mL of
geniusboy [140]

The molarity of the diluted solution is 0.33 M

From the question given above, the following data were obtained:

Molarity of stock solution (M₁) = 0. 5 M

Volume of stock solution (V₁) = 100 mL

Volume of diluted solution (V₂) = 100 + 50 = 150 mL

<h3>Molarity of diluted solution (M₂) =? </h3>

The molarity of the diluted solution can be obtained by using the dilution formula as illustrated below:

<h3>M₁V₁ = M₂V₂</h3>

0.5 × 100 = M₂ × 150

50 = M₂ × 150

Divide both side by 150

M₂ = 50 / 150

<h3>M₂ = 0.33 M</h3>

Therefore, the molarity of the diluted solution is 0.33 M
