a side reaction occurs when acid is added to the system. which species reacts with the acid?

Answers

The reaction is a base

A side reaction occurs when acid is added to the system, so the species reacts with the acid is base.

What are acids?

Acids are those species which have a pH range in between 0 to 7, generally acids are present with hydrogen atom in their molecular formula.

If in any reaction after adding the acid, side reaction wiull occur then in this condition base will reacts with the acid as it has the opposite behavior as of acid and formation of salt & water molecules takes plavce.

Hence the needed species is base.

Answer:

Molecules in the substance gain kinetic energy and then become less tightly bound to each other.

Explanation:

According to the forces of attraction , for a substance to melt molecules  in the substance gain kinetic energy and then become less tightly bound to each other.

What are forces of attraction?

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

To find the force,

 ⇒ must know the force's formula ⇒ F = MA

M: mass of the objectA: acceleration of the object

Let's consider the information given:

cup has a mass of 0.025kg --> 'M'accelerates at a rate of 5 m/s^2 --> 'A'

Let's solve:

  [tex]F=MA=0.025kg*5m/s^2=0.125N[/tex]

Thus the force is 0.125N

Answer: 0.125N

How many moles are there in 10 dm3 of sulfur dioxide gas

Answers

Taking into account the room temperature and pressure, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.

RTP refers to Room Temperature and Pressure. Pressure is 1 atm and Temperature is 298K. In this case, one mole of any gas has a volume of 24 dm³ or 24,000 cm³. This volume is called the molar volume of a gas.

In other words, the molar volume (the amount of space occupied by one mole) of any gas is 24dm³ (1 mol of gas molecules occupies 24.0 dm³).

Therefore, the amount of volume occupied by any gas can be calculated by multiplying the number of moles of gas by 24dm³:

Volume = Moles of gas× 24 dm³

So, the number of moles can be calculated as:

Moles of gas= Volume÷ 24 dm³

In this case, you know that volume if sulfur dioxide gas is 10 dm³. So, replacing:

Moles of gas= 10 dm³ ÷ 24 dm³

Solving:

Moles of gas= 0.4167

Finally, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.
