During a laboratory experiment, 9.68 g of iron reacted with excess sulfur to form 13.8 grams of iron II sulfide. Calculate the p
Daniel [21]

Answer:

Percent yield = 90.8%

Explanation:

The reaction of Fe with S to produce FeS is:

Fe + S → FeS

<em>Where the moles of Fe added in excess of S are the moles of FeS</em>

<em />

Now, percent yield is defined as 100 times the ratio between actual yield (13.8g of FeS) and theoretical yield (15.2g FeS):

Percent yield = 13.8g / 15.2g * 100

<h3>Percent yield = 90.8%</h3>

The normal freezing point of water is 0.00 ⁰C. What is the freezing point of a solution containing450.0 mg of ethylene glycol (M
anyanavicka [17]

Answer:

Freezing T° of solution = - 8.98°C

Explanation:

We apply Freezing point depression to solve this problem, the colligative property that has this formula:

Freezing T° of pure solvent - Freezing T° of solution = Kf . m

Kf = 1.86°C/m, this is a constant which is unique for each solvent. In this case, we are using water

m = molality (moles of solute / 1kg of solvent)

We convert the mass of solvent from g to kg

1.5 g . 1kg/1000g = 0.0015 kg

We convert the mass of solute, to moles. Firstly we make this conversion, from mg to g → 450mg . 1g/1000mg = 0.450 g

0.450 g. 1mol / 62.07g = 7.25×10⁻³ moles

Molality → 7.25×10⁻³ mol / 0.0015 kg = 4.83 m

- Freezing T° of solution = 1.86°C /m . 4.83 m - Freezing T° of pure solvent

-Freezing T° of solution = 1.86°C /m . 4.83 m - 0°C

Freezing T° of solution = - 8.98°C

Salt water is which type of substance?
gavmur [86]

Answer: a. solution

Explanation:

A solution is a mixture which contains two or more than two types of components and they can be separated by physical means as well.Example: salt water

Molecule of an element is defined as the aggregate of atoms of similar elements. Example: H_2. Molecule of a compound is the aggregate of atoms of different elements in a fixed ratio by mass. Example: CO_2

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: H_2O

A pure substance is a substance which contains definite composition of only one type of component. Hence, it cannot be separated by physical means. Example: Helium, water

Which of these atoms has the largest number of neutrons in the nucleus?
viktelen [127]

Holonium and Gadolinium has the highest number of neutrons in the nucleus.

Looking at the atoms listed;

Dysprosium has 66 protons

Holonium has 67 protons

Neodymium has 60 protons

Europium has 63 protons

Gadolinium has 64 protons

Then,

Number of neutrons = Mass number - number of protons

For Dysprosium

157 - 66 = 91 neutrons

For Holonium

162 - 67 = 95 neutrons

For Neodymium

149 - 60 = 89 neutrons

For Europium

148 - 63 = 85 neutrons

For Gadolinium

159 - 64 = 95 neutrons

Hence, Holonium and Gadolinium has the highest number of neutrons in the nucleus.
