Answer:
Compounds 1 and 2 are not the same
Explanation:
To solve this question we need to find the molecular formula of the compounds converting the mass of each atom to moles.
<em>Molecular formula is defined as the simplest whole number ratio of atoms present in a molecula:</em>
<em />
Compound 1:
<em>Moles Tin: </em>
5.63g Sn * (1mol / 118.7g) = 0.04743 moles
<em>Moles Cl:</em>
3.37g Cl * (1mol / 35.45g) = 0.09506 moles
Ratio Cl:Sn
0.09506 moles / 0.04743 moles = 2
Molecular formula SnCl₂
Compound 2:
<em>Moles Tin: </em>
2.5g Sn * (1mol / 118.7g) = 0.02106 moles
<em>Moles Cl:</em>
2.98g Cl * (1mol / 35.45g) = 0.08406 moles
Ratio Cl:Sn
0.08406 moles / 0.02106 moles = 4
Molecular formula SnCl₄
Compounds 1 and 2 are not the same because molecular formulas are different.
1 mole of butane uses 4.5 moles of oxygen
0.1 mole of butane will use = 0.1 * 4.5 = 0.45 moles
P = 100 kPa = 100,000Pa
n = 0.45
T = 295 K
V = ?
Using PV = nRT
⇒ 100,000 * V = 0.45 * 8.314 * 295
⇒100,000 V = 1103.68
⇒ V = 1103.68/100,000 m³
⇒ V = 1103.68/100,000 * 1000 dm³
⇒ V = 11.036 dm³
You need 11.036 dm³ oxygen.
Answer:
1. Gases can be easily liquefied into very small volumes and stored in liquid form Eg in LPGA cylinders and used in homes.
2. Balloons can be easily filled with air.
A submarine or a ship can float because the weight of water that it displaces is equal to the weight of the ship. ... To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below).
Answers:
It would seem that it would be B..... you'd have to decrease the buoyant force by removing the air from the dive tanks and filling them with water. And in a way it's C - by allowing water into the dive tanks, you are balancing the weight of the sub with the water around it.
