Answer:

Explanation:

At three-quarters of a teaspoon of baking soda, the cookie's texture becomes fragile like that of a soda cracker, with a deeply roasted flavor that distracts from the ginger.

Suppose a compound is involved in three different reactions denoted R1, R2, and R3. Tripling the concentration of this reactant

pickupchik [31]

Answer:

The order of reaction is as follows, R1 = 1; R2 = 2; R3 = 0

Explanation:

The rate of a chemical reaction is the number of moles of reactants consumed per unit time or the number of moles of products formed per unit. the rate of a chemical reaction is affected by the concentration of reactants

The relationship between the rate of a chemical reaction and the concentration of its reactants is given by the rate law or equation.

Generally, the rate equation is given as;

Rate = k[A]ᵃ[B]ᵇ..., where k = rate constant which is independent of concentration of the reactants, [A] = concentration of reactant A, a = order of reaction A, [B] = concentration of reaction B, b = order of reaction B.

For the given reactions R1, R2 and R3

For R1; rate = 3, Concentration = 3[A]

3 = k[A]3ˣ

3¹ = k[A]3ˣ

Since rate is proportional to concentration, therefore, the order of reaction, x = 1

For R2; rate = 9, Concentration = 3[A]

9 = k[A]3ˣ

3² = k[A]3ˣ

Since rate is proportional to concentration, therefore, the order of reaction, x = 2

For R1; rate = 1, Concentration = 3[A]

1 = k[A]3ˣ

3⁰ = k[A]3ˣ

Since rate is proportional to concentration, therefore, the order of reaction, x = 0

Therefore, the order of reaction is as follows, R1 = 1; R2 = 2; R3 = 0

After distilling your crude methyl benzoate, you set aside 5.12 grams of the purified ester. You then prepare the grignard reage

marysya [2.9K]

Answer:

Percent yield is 54%

Explanation:

The Grignard reaction is:

Mg + bromobenzene → phenylmagnesium bromide

Moles of Mg are:

2,3g×(1mol/24.3g) = 0.095 moles Mg.

Moles of bromobenzene are:

9,45mL×(1.495g/1mL)×(1mol/157.01g)= 0.0900 of bromobenzene.

The limiting reactant is bromobenzene. That means moles of phenylmagnesium bromide are 0.0900 moles.

To produce triphenyl carbinol you require:

2 phenylmagnesium bromide + methyl benzoate → triphenyl carbinol

Moles of methyl benzoate are:

5.12g×(1mol/136,15g) = 0.0376 moles of methyl benzoate.

The complete reaction of 0.0376 moles of methyl benzoate requires:

0.0376 moles of methyl benzoate× $\frac{2mol PhenylmagnesiumBromide}{1molMethylBenzoate}$ = 0.0752 moles of phenylmagnesium bromide. As you have 0.900 moles of phenylmagnesium bromide, limiting reagent is Methyl benzoate and moles of triphenyl carbinol are 0.0376. In grams:

0.0376 moles of triphenyl carbinol×(260.33g/mol) = 9,79g of triphenyl carbinol -This is the teorethical yield-

Percent yield is the ratio of actual yield to the theoretical yield. That is:

5,3g / 9,79g ×100 = 54%

I hope it helps!

A mineral is scratched by apatite but not by calcite what could it’s hardness value be

mojhsa [17]

Answer:

hi!

Explanation:

The Mohs Hardness Scale ranks the order of hardness of minerals and some common objects. For example, your fingernail can scratch the minerals talc and gypsum, with a hardness of 2 or lower. A copper penny can scratch calcite, gypsum, and talc.

One of the most important tests for identifying mineral specimens is the Mohs Hardness Test.

This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left).

The test is useful because most specimens of a given mineral are very close to the same hardness. This makes hardness a reliable diagnostic property for most minerals.

"Hardness" is the resistance of a material to being scratched. The test is conducted by placing a sharp point of one specimen on an unmarked surface of another specimen and attempting to produce a scratch.

Hydrogen gas is explosive within the range of 4% - 75% v/v. Assuming that each student in your class produces 6 L of H2 and that

yan [13]

In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
