Alla [95]3 years ago

Answer:

The 50 per cent figure for people and bananas roughly means that half of our genes have counterparts in bananas. For example, both of us have some kind of gene that codes for cell growth, though these aren't necessarily made up of the same DNA sequences.Humans share 50% of our DNA with a banana. Twenty five per cent of all of your bones are in your feet. The average person walks the equivalent of three times around the world in a lifetime.Humans don't just share a high percentage of DNA with bananas – we also share 85 percent DNA with a mouse and 61 percent with a fruit fly. "The remarkable thing is that despite being very far apart in evolutionary time, we can still find a common signature in the genome of a common ancestor.

Iron is found in Earth's crust as several iron compounds. Calculate the mass in kilograms of the amount of each of the following
notka56 [123]

The mass of hematite that contains 8.0×10³ kg of iron is 2.29 × 10⁴ kg.

<h3>What are iron ores?</h3>

Iron ores refers to minerals in which iron occur in combined form found in the earth's crust.

Some ores of iron include:

  • hematite,
  • magnetite,
  • limonite, and
  • siderite.

Molar mass of hematite, Fe₂O₃ = 160 g/mol

Molar mass iron = 56 g/mol

Percent mass of iron in hematite = 56/160 = 35%

The mass of hematite that contains 8.0×10³ kg of iron = 8.0 × 10³kg/0.35 = 2.29 × 10⁴ kg.

Therefore, the mass of hematite that contains 8.0×10³ kg of iron is 2.29 × 10⁴ kg.

How many moles of Al are necessary to form 23.6 g of AlBr₃ from this reaction: 2 Al(s) + 3 Br₂(l) → 2 AlBr₃(s) ?
Gnoma [55]

Answer:

0.088 mole of Al.

Explanation:

First, we shall determine the number of mole in 23.6 g of AlBr₃.

This is illustrated below:

Mass of AlBr₃ = 23.6 g

Molar Mass of AlBr₃ = 27 + 3(80) = 267 g/mol

Mole of AlBr₃ =.?

Mole = mass/Molar mass

Mole of AlBr₃ = 23.6 / 267

Mole of AlBr₃ = 0.088 mol

Next, we shall writing the balanced equation for the reaction.

This is given below:

2Al(s) + 3Br₂(l) → 2AlBr₃(s)

From the balanced equation above,

2 moles of Al reacted with 3 mole of Br₂ to 2 moles AlBr₃.

Finally, we shall determine the number of mole of Al needed for the reaction as follow:

From the balanced equation above,

2 moles of Al reacted to 2 moles AlBr₃.

Therefore, 0.088 mole of Al will also react to produce 0.088 mole of AlBr₃.
