The statement that best describes the charges of the particles is : ( A ) A neutral particle is striking a positive particle, breaking it into more

The collision of Neutral and postitve particles leads to the production of more negative and positive particles. Due to the neutral force and this leads to the production of an electrical charges.  

Hence a neutral particle striking a positive particle will lead to the production of more positive particle.

Answer:

The prediction of the student about the amount of reactant and product is incorrect.

No, I do not agree with the student’s prediction because the amount of reactant is always equals to the amount of product. According to the Law of Conservation of Mass, mass cannot be created nor destroyed. Therefore in any chemical reaction the mass of the products must equal or same to the mass of the reactants so according to this law, the prediction of the student is incorrect.

Explanation:Give brailiest please

Answer:

The chemical reaction that occurs when vinegar and baking soda (sodium bicarbonate) are combined, creates a gas that is known as carbon dioxide (or CO2). I would agree with the student's prediction because the atoms rearrange themselves to create the product.

Answer:

We are releasing the stored carbon into the atmosphere

Explanation:

We are releasing the stored carbon into the atmosphere, thus increasing the amount of CO2 in the atmosphere. We are releasing the carbon stores faster than they can be replenished by nature.

Our use of carbon stores increases the amount of carbon dioxide in the atmosphere.

Carbon stores are those places present in the environment in which carbon is present in its different composition.

As it is present in the soil in the form of organic molecules and as a deposit in the sedimentary rocks of earth such as limestones, dolomite and in the deep oceans. If we uses these carbon stores then as a result carbon dioxide releases in the environment and increases its level.

Hence amount of carbon dioxide increases.

An atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.

An ion is a charged atom while an isotope is the atoms of an element with the same atomic number but different atomic mass.

For example; Mg2+ is the ionic form of Magnesium while C-12 and C-14 are isotopes of carbon.

Here the ion of an atom will have a different charge but the same mass.

Also The isotope of an atom will have a different mass.

The number of protons V/S the more general atom, an ion has a different number of electrons, and an isotope, a different number of neutrons.

Hence atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.

Ionic solutions are known to be electrolytes due to the presence of free ions. Covalent solutions are non-electrolytes hence the decrease the conductivity of the ionic solutions.

Electrolytes are solutions that conduct electricity. The charge carriers in solution are ions. These ions are mobile. Covalent substances are molecular in nature. They do not contain ions hence they do not give ions when dissolved in water.

The conductivity of ionic solutions owes to the presence of ions in solution. The higher the concentration of ions in solution, the greater the conductivity of the solution. When covalent substances are mixed with ionic solutions, the concentration of ions decreases and the conductivity of the solution decreases.

For the water to H2 and O2 problem:

1) Reactant is H20, it is to the left of the arrow.

2) Products are H2 (gas) and O2 (gas) because it is to the right and what is created.

For the CO2 + water -> Glucose + Oxygen problem:

1) Reactant is CO2 and H2O, it is to the left of the arrow and what is being changed.

2) Products are C6H12O6 (glucose) and O2 (gas) because it is to the right and what is created.

Answer: (although the question does not sate whether if you separate them physically or through energy. so i did both)

1. can be separated (When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen)

2. can be separated, but through electrolysis, fiscally moving a crane to generate electricity to separate the molecules

3. Most solid particles, composed of diamagnetic or weak paramagnetic materials, cannot be extracted by a conventional magnetic separator. physically cannot be separated. but through heat yes

4. but there is a catch: doing so requires energy. ... If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient. so it cant be separated physically

5. it can be separated but it needs energy physically cannot be separated.

The amount of Mg(OH)2  present after the reaction is complete is 0.136 moles of Mg(OH)2.

The equation of the reaction is;

2HNO3(aq) + Mg(OH)2(aq) -------> Mg(NO3)2(aq) + 2H2O(l)

Number of moles of Mg(OH)2 = 8.00 g/58 g/mol = 0.138 moles

Number of moles of HNO3 = 0.205 M × 24.2 mL/1000 = 0.00496 moles

Given that;

2 moles of HNO3 reacts with 1 mole of Mg(OH)2

0.00496 moles of HNO3 reacts with 0.00496 moles ×  1 mole /2 moles = 0.00248 moles of Mg(OH)2

Hence, Mg(OH)2 is the reactant in excess.

The amount of Mg(OH)2 remaining = Amount present - Amount reacted

Hence; 0.138 moles - 0.00248 moles = 0.136 moles of Mg(OH)2

Explanation:

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Answer: 2nd answer " C "

Explanation:

First ionization energy is a periodic trend that increases up and to the right on the periodic table. After looking at the position of these elements on the periodic table, carbon is clearly the best answer-choice (B) aka " C "
