Answer: Its so much larger because it has a core.
Explanation:
Jupiter is proven to have a core, the planet still could have formed that core through disk instability. Enough dust could have collected and cemented together in the dense gas to form a core many times larger than the size of the Earth
Answer: 208g/mol
Explanation:
First of all we have to write the balance equation for the reaction.
BaCl2 + Fe2(SO4)3____> BaSO4 + FeCl3
After balancing we have.
3BaCl2 +Fe2(SO4)3_____> 3BaSO4 +2FeCl3
Looking at the equation, we find out that 3 moles of barium chloride reacts with 1 mole of iron iii sulfate
Therefore we have
3moles of BaCl2 _____> 400g/mole of iron iii sulfate
Xmole of BaCl2 _____> 200g/mole of iron iii sulfate
X = 2 * 200g/mol divide by 400g/mol
X = 1mole
1 mole of BaCl2 will be need to react with 200g/mol of iron iii sulfate.
This 1 mole of BaCl2 is equivalent to 208g/mol of BaCl2.
Therefore the gram of barium chloride that must be present is = 208g/mol//
Answer: -
- 0.348°C is the melting point of a solution in which 2.5 grams of sodium chloride is added to 230 mL of water
Explanation: -
Mass of NaCl = 2.5 g
Molar mass of NaCl = 23 x 1 + 35.5 x 1 = 58.5 g / mol
Number of moles of NaCl = Mass of NaCl / Molar mass of NaCl
= 2.5 /58.5
= 0.043 mol
230mL of water has 0.043 mol.
1000mL of water has (0.043 mol x 1000 mL ) / 230mL
= 0.187 mol
Thus molality of NaCl =0.187 m
The molal freezing point depression constant of water = 1.86 °C/m
Depression in freezing point = 1.86 °C/m x 0.187 m
= 0.348°C
Melting point = 0 - 0.348°C
= - 0.348°C
The most common hydrogen carbon fuels are ethanol and diesel and their product of combustion is carbon dioxide, water and heat .
