Answer:
b. An Interstitial Alloy
b. a substitutional alloy
Explanation:
A homogeneous mixture is simply any mixture in which each substance is mixed such that it is indistinguishable from the others.
A simple solution consists of solvent and solute that are evenly mixed. A solute is the substance to be dissolved and the solvent is the one in which the solute is dissolved.
When some atoms of the solvent are replaced by solute atoms of a similar size, the solution is called <u>an Interstitial Alloy</u>
When atoms of the solute occupy small holes between the solvent atoms, the solution is called <u>a substitutional alloy</u>
Answer:
The polar compounds are soluble in water while non polar are insoluble in water.
Explanation:
Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.
Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.
Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.
Example:
when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.
Answer: 510 L of oxygen gas were consumed.
Explanation:
According to ideal gas equation:
P = pressure of gas = 750 torr = 0.99 atm (760 torr= 1atm)
V = Volume of gas = 620 L
n = number of moles of carbon dioxide = ?
R = gas constant =
T =temperature =
According to stoichiometry:
8 moles of are produced by = 13 moles of oxygen
Thus 9.08 moles of are produced by = moles of oxygen
P = pressure of gas = 540 torr = 0.71 atm (760 torr= 1atm)
V = Volume of gas = ?
n = number of moles of oxygen = 14.8
R = gas constant =
T =temperature =
Thus 510 L of oxygen gas were consumed.
<u>Answer:</u> The percent composition of in taconite is 37.6 %.
<u>Explanation:</u>
We are given:
Mass of taconite pellets = 1 ton = 907185 g (Conversion factor: 1 ton = 907185 g)
Mass of iron produced = 545 lb = 247212 g (Conversion factor: 1 lb = 453.6 g )
We know that:
Molar mass of iron = 55.85 g/mol
Molar mass of = 231.53 g/mol
1 mole of contains 3 moles of iron atom and 4 moles of oxygen atom
(3 × 55.85) = 167.55 g of iron is produced from 231.53 grams of
So, 247212 grams of iron will be produced from = of
To calculate the percentage of in taconite, we use the equation:
Mass of taconite = 907185 g
Mass of = 341611.43 g
Putting values in above equation, we get:
Hence, the percent composition of in taconite is 37.6 %.
I know this isn't much use but I'd guess at either C or D
