Answer:

b) 7

Explanation:

The pH of a solution produced by the neutralization reaction between 1M of H₂SO₄ and KOH with 1M is closest to 7.

pH is a standard for measuring the acidity and alkalinity of a solution. A solution that is acidic will have a pH less than 7, a neutral solution will have pH of 7 and a basic solution will have pH greater than 7.

What is a neutralization reaction?

It is an acid-base reaction in which hydrogen and hydroxide ions combines to form water.
Also a salt results from the combination of the other ions.

In this reaction a base simply neutralizes an acid and the solution becomes neutral before it goes into completion.

Therefore, a neutral solution will have pH of 7 or close to it.

A gas occupies 11.2 L at a pressure of 35.0 mm . What is the volume of the gas if it is Increased to a pressure of 64.0 mm Hg?

Alchen [17]

Explanation:

$from \: boyle's \: law \\ P _{1} V _{1} = P _{2} V _{2} \\ 35 \times 11.2 = 64 \times V _{2} \\ V _{2} = \frac{35 \times 11.2}{64} \\ V _{2} = 6.125 \: L$

The enthalpy change for the explosion of ammonium nitrate with fuel oil is –7198 kJ for every 3 moles of NH4NO3. What is the ent

anastassius [24]

Answer:

−2399.33 kJ

Explanation:

If NH₄NO₃ reacts with fuel oil to give a ΔH of -7198 for every 3 moles of NH₄NO₃

What is the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction

∴ For every 1 mole, we will have $\frac{1}{3}$ of the total enthaply of the 3 moles

so, to determine the 1 mole; we have:

$\frac{1}{3}*(-7198kJ)$

= −2399.33 kJ

∴ the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction = −2399.33 kJ

If objects with a greater mass have greater gravitational pull, why is our solar

STatiana [176]

Answer:

It's too far away

Explanation:

According to classical mechanics, gravitational pull is inversely proportional to the distance squared; as the distance increases, the gravitational pull decreases at a faster and faster rate. Since Alpha Centauri A is a few lightyears (Tens of trillions of kilometers away), without even needing to calculate the force of gravity, it is very miniscule.
