What happens when you change the number of protons keeping the numbers of other particles the same?

Ne4ueva [31]

Answer:

See explanation

Explanation:

The atomic number refers to the number of protons in the nucleus of an atom. We identify an element by its atomic number.

When the atomic number of an atom of an element is changed, we have changed the identity of that atom and transformed it into an atom of a different element.

For example, if we add a proton to a sodium atom, we create a magnesium atom. If we remove a proton from a sodium atom, we create a neon atom.

The density of gold is 19.3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ) .25 cm3 .67 cm3 1.48 cm3 2.50 cm3

zhannawk [14.2K]

Answer:

<h3>The answer is 0.67 cm³ </h3>

Explanation:

Density of a substance can be found by using the formula

<h3> $Density = \frac{mass}{volume}$ </h3>

Making volume the subject we have

<h3> $volume = \frac{mass}{Density}$ </h3>

From the question

mass of gold nugget = 13 g

Density = 19.3 g/cm³

Substitute the values into the above formula and solve for the volume

We have

<h3> $volume = \frac{13}{19.3}$ </h3>

= 0.673575

We have the final answer as

Hope this helps you

Write a half-reaction for the oxidation of the manganese in MnCO3(s) to MnO2(s) in neutral groundwater where the carbonate-conta

Sergeu [11.5K]

Answer:

The half-reaction for the oxidation of the manganese in $MnCO_3(s)$ to $MnO_2(s)$ .:

$MnCO_3+2H_2O\rightarrow MnO_2(s)+HCO_3^{-}+3H^+$

Explanation:

$MnCO_3+H_2O\rightarrow MnO_2(s)+HCO_3^{-}$

Let us say the medium in which reaction is taking place is an acidic medium. And balancing in an acidic mediums done as;

Step 1: Balance all the atom beside oxygen and hydrogen atom;

$MnCO_3+H_2O\rightarrow MnO_2(s)+HCO_3^{-}$

Manganese and carbon are balanced.

Step 2: Balance oxygen atom adding water on the required side:

$MnCO_3+H_2O+H_2O\rightarrow MnO_2(s)+HCO_3^{-}$

$MnCO_3+2H_2O\rightarrow MnO_2(s)+HCO_3^{-}$

Step 3: Now balance hydrogen atom by adding hydrogen ion on the required side:

$MnCO_3+2H_2O\rightarrow MnO_2(s)+HCO_3^{-}+3H^+$
