Answer:

The correct answer is option C. An acidic solution has only hydrogen ions and a basic solution has only hydroxide ions.

Explanation:

Hello!

Let's solve this!

Acids are substances that only contain hydrogen ions, also the pH is less than 7. A base is a substance that contains hydroxide ions and a pH greater than 7.

After the analysis, we conclude that the correct answer is option C. An acidic solution has only hydrogen ions and a basic solution has only hydroxide ions.

In bullet points: explain the difference between thermal energy, heat and temperature.
sergeinik [125]
  • Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

  • Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

  • Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.

A compressor takes 0.50 m3 of a gas at 33°C and 760 mmHg and compresses it to 0.10 m3, cooling it to -55°C at the same time. Wha
vodomira [7]

Answer is C.

Converting temperatures to degrees K: 33 degrees C = 306 K and -55 = 218 degrees K.

By the ideal gas law:-

760 * 0.50 / 306  = P * 0.10 / 218    

P =  760 * 0.50 * 218 / 306 * 0.10

= 2700 mm Hg  answer

How many miles of co2 are produced if 5.0 moles of c10h22 react with an excess of o2?
Naily [24]
The balanced equation for the above reaction is as follows;
2C₁₀H₂₂ + 31O₂ ---> 20CO₂  + 22H₂O
stoichiometry of C₁₀H₂₂ to CO₂ is 2:20
this means that for every 2 mol of C₁₀H₂₂ that reacts - 20 mol of CO₂ is formed 
therefore when 5.0 mol of C₁₀H₂₂ reacts - 20/2 x 5.0 = 50 mol of CO₂ is formed 
50 mol of CO₂ is produced.

Limescale removers contain sulfamic acid, H3NSO3, which reacts with minerals in hard water
I am Lyosha [343]

Answer:

0.375 moles of CaCO₃ are required

Explanation:

Given data:

Number of moles of sulfamic acid = 0.75 mol

Number of moles of calcium carbonate required = ?

Solution:

Chemical equation:

2H₃NSO₃ + CaCO₃     →        Ca(SO₃NH₂)₂ + CO₂ + H₂O

Now we will compare the moles of H₃NSO₃  and CaCO₃ .

                H₃NSO₃           :            CaCO₃  

                     2                 :             1

                   0.75              :           1/2×0.75 = 0.375 mol

Thus, 0.375 moles of CaCO₃ are required.
