4 neutrons that are produced along with the Zn and sm. The complete final equation is:  ²³⁵U + ¹n → \;^{72}Zn+\;^{160}sm + 4 n

<h3>What atomic mass?</h3>

Atomic mass, the quantity of matter contained in an atom of an element.

1) In the left side of the transmutation equation appears:

²³⁵U + ¹n →

Deleting the atomic number (subscript to the left) because the question does not show them as it is focused on a number of neutrons.

2) The right side of the transmutation equation has:

→ \;^{72}Zn+\;^{160}sm +?

3) The total mass number of the left side is 235 + 1 = 236

4) The total mass number of Zn and sm on the right side is 160 + 72 = 232

5) Then, you are lacking 236 - 232 = 4 unit masses on the right side which are the 4 neutrons that are produced along with the Zn and sm.

The complete final equation is:

²³⁵U + ¹n → \;^{72}Zn+\;^{160}sm + 4 n

A 0.753 g sample of a monoprotic acid is dissolved in water and titrated with 0.250 M NaOH. What is the molar mass of the acid i
Alexeev081 [22]

Answer:

MM_{acid}=140.1g/mol

Explanation:

Hello,

In this case, since the acid is monoprotic, we can notice a 1:1 molar ratio between, therefore, for the titration at the equivalence point, we have:

n_{acid}=n_{base} \\\\V_{acid}M_{acid}=V_{base}M_{base}\\\\n_{acid}=V_{base}M_{base}

Thus, solving for the moles of the acid, we obtain:

n_{acid}=0.0215L*0.250\frac{mol}{L}=5.375x10^{-3}mol

Then, by using the mass of the acid, we compute its molar mass:

MM_{acid}=\frac{0.753g}{5.375x10^{-5}mol} \\\\MM_{acid}=140.1g/mol

Regards.

Nikolay [14]

Answer:

Charge

Explanation:

A surplus (having "extra") or deficit (having "fewer") of electrons possessed by an object. A charge can cause attractive or repulsive forces which can be observed in some cases (e.g. pith balls, bits of plastic).

How many moles of gold are equivalent to 1.204 × 1024 atoms?
LUCKY_DIMON [66]

Explanation:

It is known that the value of Avogadro's number is 6.022 \times 10^{23}.

Therefore, calculate moles of gold atoms as follows.

    Moles of gold atom = \frac{given number of atoms}{Avogadro's number}

                                    = \frac{1.204 \times 10^{24}}{6.022 \times 10^{23}mol^{-1}}

                                    = 0.199 \times 10 mol

                                    = 1.99 mol

Thus, we can conclude that 1.99 mol of gold atoms are equivalent to 1.204 \times 10^{24} atoms.
