5 0

Answer:

C. Electrons equal the number of protons

Explanation:

An atom is electrically neutral because...

a. Neutrons equal the number of protons

b. Proton forces pull on the neutrons

C. Electrons equal the number of protons

d. Electrons equal the number of neutrons

to be electrically neutral, the number os positive charges from thethe negative charges from the electrons

so

the number of protons must  equal the number of electrons

ignore neutrons,  they have NO charge

so

C. Electrons equal the number of protons

Fission reactions are induced in nuclear power plants because they produce great amounts of energy. Often, a nucleus must be for
alex41 [277]

Answer:

Chain reaction

Explanation:

A chain reaction is a reaction that sustains itself. It has the ability to continue for a very long time without adding any more materials to the reaction system. It may be succinctly described as a self propagating reaction.

In a nuclear fission, uranium-235 is bombarded with neutrons to produce unstable uranium-236 which disintegrates to form daughter nuclei and produce more neutrons that bombard more uranium-235 and the reaction continues indefinitely.

Consider the balanced equation. 2HCl + Mg MgCl2 + H2 If 40.0 g of HCl react with an excess of magnesium metal, what is the theor
Serga [27]

Answer:

Theoretical yield of hydrogen is 1.11 g

Explanation:

Balanced equation, Mg+2HCl\rightarrow MgCl_{2}+H_{2}

As Mg remain present in excess therefore HCl is the limiting reagent.

According to balanced equation, 2 moles of HCl produce 1 mol of H_{2}.

Molar mass of HCl = 36.46 g/mol

So, 40.0 g of HCl = \frac{40.0}{36.46}moles of HCl = 1.10 moles of HCl

Hence, theoretically, number of moles of H_{2} are produced from 1.10 moles of HCl = (\frac{1}{2}\times 1.10)moles=0.550moles

Molar mass of H_{2} = 2.016 g/mol

So, theoretical yield of H_{2} = (0.550\times 2.016)g=1.11g

[OH-] for a solution is
solong [7]

Answer:

B = basic

Explanation:

Given data:

[OH⁻] = 5.35×10⁻⁴M

pH = ?

Solution:

pOH = -log[OH⁻]

pOH = - [5.35×10⁻⁴]

pOH = 3.272

it is known that,

pH + pOH = 14

pH = 14- pOH

pH = 14 - 3.272

pH = 10.728

The acidic pH is range from zero to less than 7 while 7 pH is neutral and above 7 the pH is basic. So, the given solution is basic.
