How many moles of glucose does 1.2 x 1024 molecules represent? 1 mole of any substance has 6.02 x 1023 . For getting thenumber of moles we can divide 1.2 x 1024/6.02 x 1023 and we receive 2 moles.

The mass of ethanol (alcohol) = 538.016 g

Given

Reaction

C₁₂H₂₂O₁₁(aq)+H₂O(I) = CH₃CH₂OH(aq)+CO₂(g)

1 kg of sugar = 1000 g

Required

The mass of ethanol

Solution

Balanced equation

C₁₂H₂₂O₁₁(aq)+H₂O(I) = 4CH₃CH₂OH(aq)+4CO₂(g)

mol of sugar (MW = 12.12+22.1+11.16=342 g/mol) :

mol = mass : MW

mol = 1000 g : 342 g/mol

mol = 2.924

From the equation, mol ratio of C₁₂H₂₂O₁₁ : CH₃CH₂OH = 1 : 4, so mol ethanol =

= 4 x mol sugar

= 4 x 2.924

= 11.696

Mass of ethanol(MW=46 g/mol) :

mass = mol x MW

mass = 11.696 x 46

mass = 538.016 g

Answer:

Explanation:

Iodine-127 (80%)

Iodine-126 (17%)

Iodine-128 (3%)

For a mixture of isotopes, the average atomic mass is obtained by summing the multiplication of the atomic mass and percentage composition of the individual isotopes. This is given as;

Average Atomic Mass =  ( 80 / 100 *   127)  +  (17 / 100 *  126)   +  (3 / 100   *   128)

Average Atomic Mass =  0.8  *  127   +   0.12  *  126   +  0.03  *  128

Average Atomic Mass = 101.6  + 21.42 + 3.84  = 126.86

Explanation:

The two isotopes of lithium given are similar in the sense that they have the same atomic number which is 3.

Every kind of an atom of an element have the same atomic number. Atomic number is the number of protons in an atom.

The atoms are different in that they have different mass number because the number of protons they contain are different.

Answer:

When water forms beads on a surface, as it does on the hood of a freshly waxed car, we can say that the water is minimizing its contact with the surface because the cohesive forces are larger than the adhesive forces

Explanation:

A waxed car's surface is covered wax which is an hydrocarbon having long chains that are very hydrophobic and therefore there is little interaction between the surface covered in wax and the cohesive forces in the water is much larger than the adhesive forces between the water and the freshly waxed car's surface which makes the water bead up to minimize the contact surface with the car's metal surface that results in limiting of the rust.

The percentage yield : 79.67%

The closest answer is option B.

Given

125.4 g C3H8

157.4 g C3H8

Required

The percentage yield

Solution

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

% yield = (actual yield : theoretical yield) x 100%

Input the value :

% yield = (125.4 : 157.4) x 100%

% yield = 79.67

Answer:

d = distance traveled by her on her bicycle on a long flat road = 24 kilometer

t = time taken by her to travel distance "d" on her bicycle on a long flat road = 1.2 hours

v = average speed of vivian = ?

we know that average speed is given as

v = d/t

inserting the values in the above formula

v = 24 kilometer / 1.2 hour

v = 20 kilometer/hour

hence the correct choice is

C) 20 km/h

Answer:

[tex]C_{3}H_{3} O_{1}[/tex]

Explanation:

There are empirical formula calculators on the search engine that starts with G (This word is blocked by Brainly) and if you really need to use it, there's an option you can choose. However, I will try to explain this.

C = 65.4

H = 5.5

O = 29.1

We first need to divide the percentages by their molar mass.

65.4/12.01 = 5.44

5.5/1.008 = 5.46

29.1/16 = 1.8

We then need to divide these numbers by the smallest number we obtained.

1.8 is smaller than 5.46 and 5.46, so we would divide all three numbers with 1.8.

5.44/1.8 = 3

5.46/1.8 = 3

1.8/1.8 = 1

This means that there are 3 atoms of C and H and 1 atom of O, giving us the empirical formula of [tex]C_{3}H_{3} O_{1}[/tex].

The missing product : MgCl₂

Given

The reaction between Mg and FeCl₃

Required

The missing product

Solution

This reaction is a single replacement reaction

Occurs when one element replaces another element in the compound. The more active element will replace the less active element. The activity of this element can be seen from the voltaic series

Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au

Mg is located to the left of Fe in the voltaic series so that it can replace Fe from its compound

General formula :

A + BC ⇒ AC + B

So the reaction :

3Mg + 2FeCl₃ → 2Fe + 3MgCl₂
