A, a heterogeneous mixture is a mixture where all the particles are not made up of one uniform composition. you can distinguish the different particles
Answer:
The value of the Golden Igloo is $227.4 million.
Explanation:
First, we need to find the inner and the outer volume of the half-spherical shell:


The total volume is given by:

Where:
: is the inner volume
: is the inner radius = 1.25/2 = 0.625 m
: is the outer volume
: is the outer radius = 1.45/2 = 0.725 m
Then, the total volume of the Igloo is:
![V_{T} = \frac{2}{3}\pi r_{o}^{3} - \frac{2}{3}\pi r_{i}^{3} = \frac{2}{3}\pi [(0.725 m)^{3} - (0.625 m)^{3}] = 0.29 m^{3}](https://tex.z-dn.net/?f=%20V_%7BT%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r_%7Bo%7D%5E%7B3%7D%20-%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r_%7Bi%7D%5E%7B3%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20%5B%280.725%20m%29%5E%7B3%7D%20-%20%280.625%20m%29%5E%7B3%7D%5D%20%3D%200.29%20m%5E%7B3%7D%20)
Now, by using the density we can find the mass of the Igloo:

Finally, the value (V) of the antiquity is:
Therefore, the value of the Golden Igloo is $227.4 million.

Answer:
HCl is the correct answer
<h3>
Answer:</h3>
15 moles
<h3>
Explanation:</h3>
The decomposition of boron carbonate is given by the equation;
B₂(CO₃)₃(s) → B₂O₃(s) + 3CO₂(g)
Moles of boron carbonate decomposed is 5.0 mol
To find the moles of CO₂ produced we are going to use the mole ratio.
Mole ratio of B₂(CO₃)₃ to CO₂ is 1 : 3
Therefore;
Moles of CO₂ = Moles of B₂(CO₃)₃ × 3
= 15 mol
Therefore, 15 moles of CO₂ will be produced
