Explain how our kidneys filter water and how the universal solvent properties important in that process

1 answer:

7 0

Kidneys filter water as Kidneys filter the substance that enters our body using water because water dissolves these substance and send them out of our body. The universal property of water plays a important role in this process as it wash out a great portion even all the substance in our body.

So kidneys filter water and the universal solvent properties plays a important role in that process.

How many electrons are transferred during the formation of one molecule of al2o3?

lukranit [14]

Answer:
Six electrons are transferred in the formation of Al₂O₃.

Explanation:
Aluminium metal and Oxygen react to form Al₂O₃ as,

2 Al + 3/2 O₂ → Al₂O₃

Oxidation number of Al on left hand side is zero, while than on right hand side in Al₂O₃ is +3. Means it has lost 3 electrons per one atom and six electrons per two atoms. Also, the oxidation number of O at left hand side in O₂ is zero, while that in Al₂O₃ it is -2 per atom and -6 per 3 atoms.

So, two Al atoms have lost 6 electrons and 3 O atoms have gained six electrons.

The population of the Earth at the end of 2018 was approximately 7.7 × 10 9 people. Which of the following is the correct way of

stepladder [879]

Answer:

7700000000

Explanation:

so 7.7 x 10 to the power of 9 is in standard form

to put it into a number you just need to times it by 1000000000

however your answer will only have 8 zeros because of the decimal point

Please help me with this one true or false

zhenek [66]

Answer:

41. False

42. True

43. False

44. False

45. True

46 - 48. Unsure (I don't take Biology, sorry.)

Explanation:

41.

FeS and HCl are the reactants of the chemical equation. Hence, false.

42.

It is common knowledge that HCl and H₂SO₄ are acids. Hence, true.

43.

Vinegar contains acetic acid CH₃COOH, which isn't a base. Hence, false.

44.

Fluorescence is actually the emittance of light by <em>any substance</em> due to radiation. Hence, false.

45.

Yes, the image produced by a plane mirror is laterally inverted. Hence, true.

How much rust is produced with 1.5 kg of Fe reacts with water

ZanzabumX [31]

Answer:

2071g or 2.071kg of rust (Fe3O4)

Explanation:

Step 1:

The balanced equation for the reaction.

3Fe + 4H2O —> Fe3O4 + 4H2

Step 2:

Determination of the mass of Fe that reacted and the mass of the Fe3O4 produced from the balanced equation.

Molar Mass of Fe = 56g/mol

Mass of Fe from the balanced equation = 3 x 56 = 168g

Molar mass of Fe3O4 = (56x3) + (16x4) = 232g/mol

Mass of Fe3O4 from the balanced equation = 1 x 232 = 232g

Summary:

From the balanced equation above,

168g of Fe reacted and 232g of Fe3O4 was produced.

Step 3:

Determination of the mass of rust (Fe3O4) produced when 1.5kg ( i.e 1500g) of Fe reacted.

This is illustrated below:

From the balanced equation above,

168g of Fe reacted to produce 232g of Fe3O4.

Therefore, 1500g of Fe will react to produce = (1500x232)/168 = 2071g of Fe3O4.

From the calculations made above, 2071g or 2.071kg of rust (Fe3O4) is produced.
