An endothermic process may be spontaneous if: C. the product particles have more freedom of motion than the reactant particles.

An endothermic reaction can be defined as a type of chemical reaction in which heat energy is absorbed from the environment.

Generally, heat energy is absorbed in a chemical reaction when the energy of the products is greater (more) than the energy of the reactants and this is referred to as an endothermic reaction.

Similarly, an endothermic process may be spontaneous when the product particles have more freedom of motion than the reactant particles.

Can someone please help me with my science research I kind of need help in a few things that I listed, I’m currently working on
dalvyx [7]

Answer:

For your first question, Curium does not occur naturally on Earth, meaning that it is not produced naturally on Earth. However, it can be formed in nuclear reactors.

For your second question, Curium has been used to provide power to electrical equipment used on space missions, but doesn't seem to be that important overall.

Making solutions is an extremely important component to real-life chemistry. If you make 3.00 L of a solution using 90.0 g of so
kumpel [21]

Answer:

Final concentration of NaOH = 0.75 M

Explanation:

For NaOH :-

Given mass = 90.0 g

Molar mass of NaOH = 39.997 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{90.0\ g}{39.997\ g/mol}

Moles\ of\ NaOH= 2.2502\ mol

Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.

The expression for the molarity, according to its definition is shown below as:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Where, Volume must be in Liter.

It is denoted by M.

Given, Volume = 3.00 L

So,

Molarity=\frac{2.2502\ mol}{3.00\ L}=0.75\ M

<u>Final concentration of NaOH = 0.75 M</u>

If 25.8 grams of BaO dissolve in enough water to make a 212-gram solution, what is the percent by mass of the solution?
Igoryamba
The correct answer is 12.2% BaO.

The solution is found by dividing the mass of the BaO, which is 25.8 grams, by the total mass of the solution, which is 212 grams, then multiplying it by 100 to get the percentage:
\frac{25.8}{212}*(100) =12.2%

It's actually Science but I didn't find it.

Answer:

Forces acting on an object may be balanced or unbalanced. When the forces  acting on an object have <u>equal</u> strength and act in opposite directions, they  are <u>balanced</u>. These forces cancel out one another, and the <u>motion</u> of the  object does not <u>change</u>.  When the forces acting on an object are <u>unbalanced</u>, they do not cancel out  one another. An unbalanced force acting on an object results in the object’s  motion <u>changing</u>. The object may change its <u>speed</u> (speed up or slow down), or it may change its <u>direction</u>.  <u>Friction</u> is a force that resists the motion or the tendency toward motion  between two objects in contact with each other.  <u>Gravity</u> is a force that pulls objects toward one another. For example, Earth  pulls all objects toward it.
