Answer. One larger, more stable nucleus.

Explanation:

Nuclear Fusion: When two small atomic nuclei fuse together to form one larger atomic nucleus. During this process a lot of energy is released which means product formed will be stable.

For example: Deuterium-Deuterium fusion leads to the formation of helium isotope.

$_{1}^{2}\textrm{H}+_{1}^{2}\textrm{H}\rightarrow_{2}^{3}\textrm{He}+_{0}^{1}\textrm{n}+3.27Mev$

Which properties, physical or chemical, were most useful in identifying the mystery powder? Explain your answer.

r-ruslan [8.4K]

The answer depends on what substances you were testing, but here are some ideas.

If all of them were white as in the typical experiment, then color is not very useful. If you were allowed to taste them, then a salty taste would be a helpful clue. If the textures were different, some crystals, like salt or sugar and others powdery, like flour or cornstarch, those properties would be helpful. If some dissolved in water,...

Is kp or kc larger (both at 300 k) for the reaction 2 nh3(g) ⇀↽ n2(g) + 3 h2(g) ? 1. they are both the same. 2. kc is larger. 3.

fgiga [73]

The equation is 2 NH3 (g) â‡€â†˝ N2 (g) + 3 H2 (g)
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.

Si se tiene 1mol de NO . cuantas moleculas de NO hay

kumpel [21]

if you have 1mol of NO. how many molecules of NO are there

Answer:

6.02 x 10²³ molecules

Explanation:

Given parameters:

Number of moles of NO = 1 mole

Unknown:

Number of molecules in NO;

Solution:

A mole of compound contains the Avogadro's number of particles.

1 mole of a substance contains 6.02 x 10²³ molecules

So, 1 mole of NO contained 6.02 x 10²³ molecules

Fluorine gas and water vapor react to form hydrogen fluoride gas and oxygen. What volume of hydrogen fluoride would be produced

mafiozo [28]

Answer:

Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.

9.587 cm^3

Explanation:

The balanced equation for the chemical reaction is shown below:

$2F_{2(g)} + 2H_{2}O_{(g)}$ ⇒ $4HF_{(g)} + O_{2(g)}$

In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:

Using STP, 1 mole of gas has a volume of 22.4 L

Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4

since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles

we can convert the moles to L by multiplying with 22.4

volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3
