Reactants: CO₂ (carbon dioxide) and H₂O (water)

Products: C₆H₁₂O₆ (glucose) and O₂ (oxygen gas)

In the chemical reaction of photosynthesis, carbon dioxide (CO₂) and water (H₂O) are the reactants. These are the substances that undergo a chemical change and are consumed during the reaction. They are necessary for the production of glucose (C₆H₁₂O₆) and oxygen gas (O₂), which are the products of photosynthesis. The reactants, CO₂ and H₂O, are converted into glucose and oxygen through the process of photosynthesis, which occurs in the chloroplasts of plant cells.

Glucose serves as an energy source for the cell and is used in various metabolic processes, while oxygen is released as a byproduct and plays a crucial role in supporting respiration in organisms that consume it. The classification of the molecules as reactants and products helps to understand the flow and transformation of matter during photosynthesis.

Answer:

133.85 K

Explanation:

Initial pressure, P₁ = 635 torr

Initial temperature, T₁ = 67.0°C = 340 K

Final pressure, P₂ = 250 torr

We need to find the new temperature. The relation between temperature and pressure is given by :

\(\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{250\times 340}{635}\\\\T_2=133.85\ K\)

So, the new temperature is equal to 133.85 K.

1.An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers ( 1 × 10−10 m, a ten-millionth of a millimeter, or 1/254,000,000 of an inch).

3.New elements aren't exactly discovered anymore. However, they can be made, using particle accelerators and nuclear reactions. A new element is made by adding a proton (or more than one) to a pre-existing element. This can be done by smashing protons into atoms or by colliding atoms with each other.

4.If an atom gains an electron, it becomes negatively charged.

If an atom loses an electron, it becomes positively charged.

At rest, K+ concentrations are higher inside neurons. K+ has the propensity to migrate out of the neuron down the concentration gradient because it can freely pass the neuronal membrane.

The inside of the cell contains more potassium ions than the outside does. The system as a whole is electrically neutral because an anion balances out each potassium ion (on either side of the membrane). As a result, there is a high concentration of sodium ions outside the cell and a high concentration of potassium ions inside. Additionally, the neuronal membrane contains specialized proteins known as channels that create gaps in the membrane that are only permeable to certain ions.

Explanation:

Answer:

the answer is D the dominant over powers the resecive traits

The new rate if the concentration of [A] is increased to 0.300 M is 0.5400 M/s.

Let's discuss it further below.

Initially, when [A] = 0.100 M, the rate = 0.0200 M/s.

rate = k[A][B]²

0.0200 M/s = k(0.100 M)([B]²)

0.0200 M/s = 0.001 k [B]²[B]² = 20.0 M/s / 0.001 = 20000 MB = sqrt(20000) = 141.4 M. rate = k(0.100 M)(141.4 M)²

rate = 0.001 M/s × 141.4² M²/s²

rate = 0.0200 M/s.

Now, we can calculate the new rate with the increased [A] of 0.300 M. rate = k[A][B]²

Now, when [A] = 0.300 M, the rate is calculated as rate = k(0.300 M)([B]²)

If we compare the initial and final rates:0.0200 M/s = k(0.100 M)(141.4 M)²

0.0200 M/s = k(0.0300 M)([B]²)141.4²

M²/s² = [B]² / 0.001[B]² = 141400 M/s

rate = k(0.300 M)(141400 M/s)²

rate = 0.001 M/s × 0.3 M × (141400 M/s)^2

rate = 0.5400 M/s

The new rate is 0.5400 M/s.

Therefore, option (E) is the correct answer.

Dalton's theory, also known as the atomic theory of matter, provides a fundamental understanding of chemical change. According to this theory, atoms are indivisible and indestructible particles that combine in fixed ratios to form compounds. In the process of chemical change, known as a chemical reaction, atoms are rearranged, but they are neither created nor destroyed.

In more detail, Dalton's theory explains that when a chemical reaction occurs, the bonds between atoms are broken and new bonds are formed, resulting in the creation of different substances. These reactions occur due to the rearrangement of atoms and the redistribution of their electrons.

For example, in the reaction between hydrogen and oxygen to form water, Dalton's theory explains that the hydrogen and oxygen atoms combine in a fixed ratio of two hydrogen atoms for every one oxygen atom. The reaction involves breaking the bonds between hydrogen and oxygen molecules and forming new bonds between hydrogen and oxygen atoms to create water molecules.

Overall, Dalton's theory provides a framework for understanding how chemical changes occur through the rearrangement of atoms and the formation of new substances with different properties.

As you are asking for chemical formula and ionic equation, then, I will assume that after the station #3 below, are the solutions you are requiring.

You are also not specifing if you want for example, result of solution 1 + solution 3. If you need that, please post that on another question.

Now for the chemical formula, you need to identify the elements in all 3 solutions, and also the type of compound.

1. Solution 2 Potassium Iodide:

In this case we have Potassium on one side, and Iodine on the other side, the symbol for those are K and l. As Potassium have the +1 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Iodide it will be -1, so, the formula will be:

KI

And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:  

K⁺ + I⁻ ------> KI

2. Solution 1 and 3, Lead (II) nitrate and Sodium carbonate:

In this case I will work with both, because both of the solution are tertiary compounds. In this cases, we have two tertiary salt, The Sodium symbol is Na, and is working with it oxydation state +1. Carbonate is an anion and have the formula CO₃ working with the oxydation state -2. Lead can work with oxidation state +2 and +4. It's symbol is Pb. Nitrate is NO₃ and works with oxydation state -1 instead.

The chemical formula and ionic equation for both will be:

Lead(II) nitrate: Pb(NO₃)₂

Sodium Carbonate: Na₂CO₃

And the net equations:

Lead nitrate: Pb²⁺ + 2NO₃⁻ ------> Pb(NO₃)₂

Copper sulfate: 2Na⁺ + CO₃²⁻ -------> Na₂CO₃

Slime is a non-Newtonian fluid and does not have a molecular structure that can be considered polar or non-polar. The term "polarity" typically refers to the distribution of electrical charge within a molecule. In the case of slime, the material is made up of polymer molecules, which are long chains of repeating units. These polymer molecules interact with each other through hydrogen bonding, which gives the material its unique properties such as being a non-Newtonian fluid. However, these interactions are not based on polarity, so it is not appropriate to describe slime as being polar or non-polar.

Answer:

The polarity of slime molecules depends on the specific type of slime. There are many different types of slime, each made up of different types of molecules.

For example, if we consider a typical type of slime made from polyvinyl alcohol (PVA), the polarity of the PVA molecules will depend on their molecular structure and the type of bonding between the atoms. PVA is a synthetic polymer made up of repeating units of vinyl alcohol, which has a polar hydroxyl group (-OH). As a result, PVA is considered to be a polar molecule.

However, the overall polarity of a slime made from PVA will also depend on the other ingredients that are present, such as borax, which is often used as a cross-linking agent to form the slime. The overall polarity of the slime will also depend on the conditions it is in, such as the temperature, pH, and the presence of other substances that could affect the polarity of the slime.

In summary, the polarity of slime molecules can be complex and depends on the specific type of slime, the ingredients that make it up, and the conditions it is in.
