<h2>Answer:</h2>

We will use dimensional analysis to solve this.

We will need to know Avogadro's number, which is 6.02 × 10²³.

4.5 mol × \frac{6.02 * 10^{23} molecules}{1 mol} = 2.71 × 10²⁴ molecules.

There are <em>2.71 × 10²⁴ molecules </em>in 4.5 moles of Ca(OH).

Answer:

a) H2SO4 + 2KOH -> 2H2O + K2SO4

b) 9.809 ml

Explanation:

Number of Moles = Mass/ Molar Mass

Therefore: Mass = Number of moles * Molar Mass

--------------------------------------------

Molar mass of H2SO4:

H2= 2.02

S= 32.07

O4= 64

--------------------------------------------

H2SO4 has the molar mass of 98.09

--------------------------------------------

the Moles of H2SO4 is given to be 0.100M

Therefore:

Mass= 98.09*0.1

          = 9.809g

---------------------------------------------------

Assuming that 1 g= 1 ml, the volume of sulfuric acid is 9.809 ml.

PLEASE HELP!!!!!!!
KonstantinChe [14]

Answer: The gas generated by two antacid tablets has a smaller volume.

Explanation:

Since the antiacid is the limiting reagent, we know that the more tablets there are, the more gas there will be.

This means that there will be more gas generated by the four antiacid tablets when compared to the two antiacid tablets, which gives us that the gas generated by the two antiacid tablets has a smaller volume.

What is the value for ΔSºreaction for the following reaction, given the standard entropy values?
Diano4ka-milaya [45]
Substituting the values:

51 + 3(131) = ΔH + 2(28) + 3(189)
ΔH = -225 J/mol

When written outside of the equation, this becomes 225 J/mol

Is the amount of water on earth always changing or is it a constant amount?​
Zolol [24]

Answer:

The amount of water on the Earth is constant, or nearly so. Actually, the amount is increasing ever so slightly due to volcanic eruptions expelling water vapor into the atmosphere, but, for all practical purposes, the amount of water (as a gas, liquid and as snow and ice) can be considered to be constant.
