Answer:

yes

Explanation:

because

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:

Increase

Less/low number

Lessen

Explanation:

Increase > Increase in temperature cause increase in volume.

Less/low number > As volume increases the number of particles to be adjusted in the same space will be lesser than before.

Lessen> At constant pressure as increase in temperature cause increase in volume so the density will lessen due to increase in volume. Density equation is given below.

Density = mass /volume

If volume increases density will get lowered.

Answer:

23: 6000560000000

24: 0.0015

25: 200

26: 0.0105

27: 600

28: 4023000

Explanation:

You have to move the decimal the same amount of times as the exponent says.

For example, like with the 6, you move it 2 decimals to the right (since it's positive), and the regular number would be 600.

Since we weren't given the moles of hydrogen, we have to find it. However, we can do it all in one step if we set up the equation correctly.

Since   Mass = moles × molar mass

&         Moles = #molecules ÷ Avogadro's Number

∴ mass = (#molecules ÷ Avogadro's Number) × molar mass

            =  (3.7 × 10⁴⁵ mcules ÷ (6.022 × 10²³ mcules/mole)) × 1.008 g/mol)

            = 6.19 × 10²¹ g

Answer: Iron

Explanation: does not react with water, but hydrochloric acid will dissolve them, displacing the hydrogen from the HCl. Iron reacts with hydrogen chloride to produce iron chloride, FeCl2 — sometimes known as ferrous chloride.

To solve such this we must know the concept of chemical reaction. Iron is the metal, which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

When metals react with acid the liberation of hydrogen gas take place.  Metal which is at top of reactivity series react with both acid and steam or liquid water. Iron is the only metals which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam or liquid water.

Therefore, iron is the metal, which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam.

Answer:

protons and electrons attract each other.

Explanation:

neutron as no charge,  proton and electron are exactly the same size but opposite. ( the opposite charge attract)

The protons possess a positive charge so they attract negatively charged electrons.

A proton can be described as a stable subatomic particle, a symbol with a positive charge of +1e elementary charge. Proton's mass is slightly less than that of a neutron but 1836 times the mass of an electron.

Protons and neutrons are jointly referred to as "nucleons" each with masses of approximately one atomic mass unit. More than one proton can be present in the nucleus of an atom. They give the attractive electrostatic central force which holds the atomic electrons.

The number of protons in the nucleus is referred to as the atomic number and is represented by the symbol Z. Since each element in the modern periodic table has a unique number of protons, its own unique atomic number, determines the chemical characteristics of the element.

As the neutrons are neutral do not carry any charge so the protons do not attract neutrons.
