In an experiment, the molar mass of the compound was determined to be 118.084 g/mol. What is the molecular formula of the compou
pishuonlain [190]

Answer:

Succinic acid

Explanation:

The most common possibility is succinic acid

As it has decimals after whole no till hundredth it contains OH and C in most of the cases .

Let's check for succinic acid

  • C4H_6O_6
  • 4(12)+4(16)+6
  • 64+48+6
  • 118u

Yes approximately equal

Molecular formula is.

(CH_2)_2(CO_2H)_2

When the concentrations of CH 3 Br and NaOH are both 0.100 M, the rate of the reaction is 0.0030 M/s. What is the rate of the re
mash [69]

Answer : The rate of the reaction if the concentration of CH_3Br is doubled is, 0.006 M/s

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

The balanced equations will be:

CH_3Br+NaOH\rightarrow CH_3OH+NaBr

In this reaction, CH_3Br and NaOH are the reactants.

The rate law expression for the reaction is:

\text{Rate}=k[CH_3Br][NaOH]

As we are given that:

[CH_3Br] = concentration of CH_3Br = 0.100 M

[NaOH] = concentration of NaOH = 0.100 M

Rate = 0.0030 M/s

Now put all the given values in the above expression, we get:

0.0030M/s=k\times (0.100M)\times (0.100M)

k=0.3M^{-1}s^{-1}

Now we have to calculate the rate of the reaction if the concentration of CH_3Br is doubled.

\text{Rate}=k[CH_3Br][NaOH]

\text{Rate}=(0.3M^{-1}s^{-1})\times (2\times 0.100M)\times (0.100M)

\text{Rate}=0.006M/s

Thus, the rate of the reaction if the concentration of CH_3Br is doubled is, 0.006 M/s

How did scientists respond to Copernicus discovery
Oksana_A [137]

Answer:

Nicolaus Copernicus developed the Heliocentric model for the Solar System in the early 1500s. He was an astronomer, and he published a book in 1532 in which he proposed that the planets orbit the Sun rather than the Earth. The church reacted with outrage, and banned the book.
