The equations that are nuclear reactions are as follows:

  • superscript 185 subscript 79 upper Au right arrow superscript 181 subscript 77
  • superscript 210 subscript 84 upper Po right arrow superscript 206 subscript 82 upper Pb plus superscript 4 subscript 2 upper He.

<h3>What is nuclear reaction?</h3>

A nuclear reaction is a reaction that involves the fission of an atomic nucleus, or the fusion of one or more atomic nuclei and/or subatomic particles in which the number of protons and/or neutrons in a nucleus changes.

The products of a nuclear reaction may contain a different element or a different isotope of the same element.

Therefore, the equations that are nuclear reactions are as follows:

  • superscript 185 subscript 79 upper Au right arrow superscript 181 subscript 77
  • superscript 210 subscript 84 upper Po right arrow superscript 206 subscript 82 upper Pb plus superscript 4 subscript 2 upper He.

Answer:

Root mean square speed = 649.205m/s

Explanation:

The root mean square speed shows the connection between the average kinetic energy of molecules and the gas temperature. it is derived from the ideal gas equation and the average kinetic energy. Vrms = square root ( 3RT/M).

A liquid has a density of 0.87g/ml. What volume is occupied by 25g of liquid
irga5000 [103]

Answer:

29 mL

Explanation:

<h3>Equation</h3>

The question needs us to find the volume of the liquid. The equation for volume using density and mass is:

Volume = Mass / Density

<h3>Solve</h3>

We can substitute the given values for density and mass into the equation:

V=\frac{25\ g}{0.87\ g/ml}

V\approx29\ mL

<h3>Additional Comments</h3>

The answer we obtained (29 mL) is rounded to two significant figures. When multiplying or dividing, the amount of significant figures in the final answer is always the least amount of significant figures in one of the values.

Below are the significant figure rules:

Nonzero digits will always be significant (eg. 54 --> 2 significant figures)

Zeroes at the beginning of a number will never be significant (eg. 0.1 --> 1 significant figure)

Zeroes between two nonzero digits will always be significant (eg. 504 --> 3 significant figures)

Zeroes following a number will always be significant if the number contains a decimal point (eg. 40.0 --> 3 significant figures)

g Calculate the [OH-] from the results of your titrations. Explain your calculations2. Calculate the [Ca2+]. Explain your calcul
RideAnS [48]

Answer:

Explanation:

*Since the titration is between the strong acid HCl and the strong base Ca(OH)2, the pH at the equivalent point should be 7. On interpolation, we will obtain that 9.50mL and 9.82 mL of HCl is required to completely neutralized the given Ca(OH)2 solution.

*pH at the equivalence point =7

we know that pH + pOH = 14

Hence pOH= 14-7=7

pOH= -log(OH-)

The concentration of OH-= 10-pH= 1X10-7 M

One reason for the low solubility may be the higher reaction temperature, Another reason is the common ion effect.
