Answer:
1.50 moles
Balanced equation: 2Fe + 3Cl₂ --> 2FeCl₃
<u>find moles of iron:</u>
moles = mass/Mr
moles = 55.8/56
moles = 0.9964 moles
<u>use molar ratio:</u>
2Fe : 3Cl₂
2 : 3
moles of Cl₂ = (0.9964/2)*3 = 1.50 moles
D.
A parent with type A B blood can ever have a child child with type O blood.
Explanation:
An offspring gets an allele for blood type from every parent. Therefore unless both parents have blood type O the offspring cannot have blood type O.
A person with blood group O means they do not blood group antigen on their red blood cells. They cannot pass the antigens to their offspring. A person with AB means they have both antigens for A & B blood groups and can pass either to any of the offspring they have.
The passing down of the blood group alleles follow the Mendelian principles of independent assortment.
Answer:
79.7 mol.
Explanation:
- It is known that every 1.0 mole of compound or element contains Avogadro's number (6.022 x 10²³) of molecules or atoms.
<u><em>Using cross multiplication:</em></u>
1.0 mole of tungsten contains → 6.022 x 10²³ atoms.
??? mole of tungsten contains → 4.8 x 10²⁵ atoms.
∴ The no. of moles of tungsten contains (4.8 x 10²⁵ atoms) = (1.0 mol)(4.8 x 10²⁵ atoms)/(6.022 x 10²³ atoms) = 79.7 mol.
Answer:
2. Translucent
4. Reflection
Explanation:
The terms translucent describes the nature of the juice and reflection perfectly fits the property of the light.
A translucent substance is one that partially allows light to pass through it. Since it is said that some of the light bounced back and some passed through, this is translucent.
Also, the light bouncing back is an indicator of reflection. Reflection is a property of light where it bounces back a surface.
