Answer: D. Potassium bromide
Answer:
The question has some details missing. here are the details ; Given the following ;
1. 43.2 g of tablet with 20 cm3 of space
2. 5 cm3 of tablets weighs 10.8 g
3. 5 g of balsa wood with density 0.16 g/cm3
4. 150 g of iron. With density 79g/cm 3
5. 32 cm3 sample of gold with density 19.3 g/cm3
6. 18 ml of cooking oil with density 0.92 g/ml
Explanation:
<u>Appropriate for calculating mass</u>
32 cm3 sample of gold with density 19.3 g/cm3
18 ml of cooking oil with density 0.92 g/ml
<u>Appropriate for calculating volume</u>
5 g of balsa wood with density 0.16 g/cm3
150 g of iron. With density 79g/cm 3
<u>Appropriate for calculating density</u>
43.2 g of tablet with 20 cm3 of space
5 cm3 of tablets weighs 10.8 g
I think the correct answer from the choices listed above is option D. When a molecular compound melts, they undergo the process of phase change from solid to liquid therefore m<span>olecules arranged in a regular pattern change to an irregular pattern. Hope this answers the question.</span>
Suppose 110.0 mL of hydrogen gas at STP combines with a stoichiometric amount of fluorine gas and the resulting hydrogen fluoride dissolves in water to form 150.0 mL of an aqueous solution. 0.032 M is the concentration of the resulting hydrofluoric acid.
<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
Now write the balanced chemical equation
H₂ + F₂ → 2HF
<h3>What is Ideal Gas ?</h3>
An ideal gas is a gas that obey gas laws at all temperature and pressure conditions. It have velocity and mass but do not have volume. Ideal gas is also called perfect gas. Ideal gas is a hypothetical gas.
It is expressed as:
PV = nRT
where,
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant
T = temperature
Here,
P = 1 atm [At STP]
V = 110 ml = 0.11 L
T = 273 K [At STP]
R = 0.0821 [Ideal gas constant]
Now put the values in above expression
PV = nRT
1 atm × 0.11 L = n × 0.0821 L.atm/ K. mol × 273 K

n = 0.0049 mol
<h3>How to find the concentration of resulting solution ? </h3>
To calculate the concentration of resulting solution use the expression

= 0.032 M
Thus from the above conclusion we can say that Suppose 110.0 mL of hydrogen gas at STP combines with a stoichiometric amount of fluorine gas and the resulting hydrogen fluoride dissolves in water to form 150.0 mL of an aqueous solution. 0.032 M is the concentration of the resulting hydrofluoric acid.
