What is the name of this structural formula?

Gamma decay is a type of radioactive decay that does not change the identity of the isotope.

During gamma decay the nucleus emits radiation without actually changing its composition. In this type of decay only energy is released but the structure is same.

So we can conclude that gamma decay is a type of radioactive decay that does not change the identity of the isotope.

Answer: 2 moles

Explanation:

We know from the equation that for every 3 moles of HCl consumed, 2 moles of water are consumed (based on the coefficients)

So, the answer is 2 moles.

The number of mole of oxygen gas, O₂ in the cylinder given the data is 0.5 mole

The mole of a substance is related to it's mass and molar mass according to the following equation:

Mole = mass / molar mass

From the question given, the following data were obtained:

Mole = mass / molar mass

Mole of O₂ = 16 / 32

Mole of O₂ = 0.5 mole

Answer:

749 grams CO₂

Explanation:

To find the amount of carbon dioxide produced, you need to (1) convert grams C₃H₈ to moles C₃H₈ (via molar mass from periodic table), then (2) convert moles C₃H₈ to moles CO₂ (via mole-to-mole ratio via reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass from periodic table). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The desired unit should be in the numerator. The final answer should have 3 significant figures because the given value (250. grams) has 3 sig figs.

Molar Mass (C₃H₈): 3(12.01 g/mol) + 8(1.008 g/mol)

Molar Mass (C₃H₈): 44.094 g/mol

1 C₃H₈ + 5 O₂ ---> 3 CO₂ + 4 H₂O

Molar Mass (CO₂): 12.01 g/mol + 2(16.00 g/mol)

Molar Mass (CO₂): 44.01 g/mol

250. g C₃H₈         1 mole C₃H₈           3 moles CO₂              44.01 g

Taking into account the definition of calorimetry, the mass of water is 35.70 grams.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where:

In this case, you know:

For granite:

For water:

Replacing in the expression to calculate heat exchanges:

For gold: Qgranite= 0.795 [tex]\frac{J}{gC}[/tex]  × 126.1 g× (51.9 °C - 92.6 °C)

For water: Qwater= 4.186 [tex]\frac{J}{gC}[/tex]× mass of water× (51.9 °C - 24.7 °C)

If two isolated bodies or systems exchange energy in the form of heat, the quantity received by one of them is equal to the quantity transferred by the other body. That is, the total energy exchanged remains constant, it is conserved.

Then, the heat that the gold gives up will be equal to the heat that the water receives. Therefore:

- Qgranite = + Qwater

- 0.795 [tex]\frac{J}{gC}[/tex]  × 126.1 g× (51.9 °C - 92.6 °C)= 4.186 [tex]\frac{J}{gC}[/tex]× mass of water× (51.9 °C - 24.7 °C)

Solving:

4,080.15465 J= 4.186 [tex]\frac{J}{gC}[/tex]× mass of water× 27.3 °C

4,080.15465 J= 114.2778 [tex]\frac{J}{g}[/tex]× mass of water

mass of water= (4,080.15465 J)÷ 114.2778 [tex]\frac{J}{g}[/tex]

mass of water= 35.70 grams

Finally, the mass of water is 35.70 grams.

The continuation of the electronic configuration would be [tex]3p^6, 4s^6, 3d^4.[/tex]

Electronic configuration, also called electronic structure, is the arrangement of electrons in energy levels around an atomic nucleus.

The initial p-orbital (the [tex]3p^3[/tex]) is incompletely filled. Thus, the first thing would be to fill it completely ([tex]3p^6[/tex]) so as to obey the orbital-filling rule. This leaves 6 more electrons.

After 3p orbital, the next orbitals are 4s, 3d, 4p, 5s, etc.

The 4s orbital will take a maximum of 2 electrons, leaving 4 more electrons.

Next would be the 3d orbital which can take a maximum of 8 electrons, but only 4 electrons are left.

Thus, the electronic configuration would be [tex]3p^6, 4s^6, 3d^4.[/tex]and elements is Vanadium (V).

The new pressure of the gas would be 994 mmHg

According to Charle's law, the pressure of a gas at a constant temperature varies inversely with its volume.

Mathematically: p1v1 = p2v2, where p1 and p2 = initial and final pressure, and v1 and v2 = initial and final volume.

In this case, v1 = 14.5 L, p1 = 720 mmHg, and v2 = 10.5 L

p2 = p1v1/v2 = 720 x 14.5/10.5 = 994 mmHg

When comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.

In an electrolytic cell, the reaction is non-spontaneous so it requires some input of energy for it to function while for a voltaic cell, the reaction is spontaneous.

Oxidation occurs at the anode and reduction occurs at the cathode.

Thus, when comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.

Answer:

The solution has a pH value of 9.3.

Explanation:

To solve this problem, we can first determine the H+ ion concentration and then use this value to calculate the pH. To find the H+ ion concentration from the OH- ion concentration, we should use Kw, which we know has a value of 1 * 10^(-14).

We can then use the following formula to solve for [H+]:

Kw = [H+][OH-]

10^(-14) = (2.02 * 10^(-5)) * [H+]

[H+] = 4.950495 * 10^(-10)

Now, we can find the pH using the formula pH = -log[H+].

pH = - log[H+]

pH = - log(4.950495 * 10^(-10))

pH = 9.3

Therefore, the correct answer is that the pH of the solution is 9.3. Note that an alternative way to solve the problem is to find the pOH from the OH- ion concentration and use the resulting value to determine the pH that way instead.
