Answer:

Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. Active faulting is considered to be a geologic hazard - one related to earthquakes as a cause.

80g of sodium hydroxide reacts with excess sulfuric acid to produce 142g of sodium sulfate. What mass of sodium hydroxide would

Ostrovityanka [42]

Answer:

Mass of sodium hydroxide needed = 28.2 g

Explanation:

Given data:

Mass of sodium hydroxide = 80 g

Mass of sodium sulfate produced = 142 g

Mass of sodium hydroxide needed = ?

Mass of sodium sulfate produced = 50 g

Solution:

Mass of sodium sulfate produced / Mass of sodium hydroxide = Mass of sodium sulfate produced / x

142 g/ 80 g = 50 g / x

x = 50 g × 80 g / 142 g

x =4000 g/ 142

x = 28.2 g

Construct a three-step synthesis of 1,2-epoxycyclopentane from cyclopentanol by dragging the appropriate formulas into the bins.

zubka84 [21]

Answer:

(1) Bromination, (2) E2 elimination and (3) epoxidation

Explanation:

In the first step, -OH group in cyclopentanol is replaced by more facile leaving group Br by treating cyclopentanol with $PBr_{3}$
In the second step, E2 elimination in presence of strong base e.g. NaOEt/EtOH produce cyclopentene
In the third step, treatment of cyclopentene with mCPBA produces 1,2-epoxycyclopentane
Full reaction scheme has been shown below

Calculate the pHpH of a 0.10 MM solution of HClHCl . Express your answer numerically using two decimal places.

alisha [4.7K]

Answer: The pH 0f 0.10 solution of HCl is 1.00

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

$HCl\rightarrow H^++Cl^{-}$

According to stoichiometry,

1 mole of $HCl$ gives 1 mole of $H^+$

Thus $0.10$ moles of $HCl$ gives = $\frac{1}{1}\times 0.10=0.10$ moles of $H^+$

Putting in the values:

$pH=-\log[0.10]$

$pH=1.00$

Thus pH 0f 0.10 solution of HCl is 1.00

Nitroglycerin (c3h5n3o9) is a powerful explosive. its decomposition may be represented by 4c3h5n3o9 → 6n2 12co2 10h2o o2 this re

professor190 [17]

The balanced chemical reaction describing this decomposition is as follows:
4c3h5n3o9 .............> 6N2 + 12CO2 +10H2O + O2

From the periodic table:
mass of oxygen = 16 grams
mass of nitrogen = 14 grams
mass of hydrogen = 1 gram
mass of carbon = 12 grams
Therefore:
mass of C3H5N3O9 = 3(12) + 5(1) + 3(14) + 9(16) = 227 grams
mass of O2 = 2(16) = 32 grams

From the balanced chemical equation:
4(227) = 908 grams of C3H5N3O9 produce 32 grams of O2. Therefore, to know the amount of oxygen produced from 4.5*10^2 grams C3H5N3O9, all we need to do is cross multiplication as follows:
amount of oxygen = (4.5*10^2*32) / (908) = 15.859 grams
