Consider the single‑step, bimolecular reaction. CH3Br+NaOH⟶CH3OH+NaBr When the concentrations of CH3Br and NaOH are both 0.120 M
GarryVolchara [31]

Answer:

Explanation:

CH₃Br+NaOH⟶CH₃OH+NaBr

It is a single step bimolecular reaction so  order of reaction is 2 , one for CH₃Br and one for NaOH .

rate of reaction = k x [CH₃Br] [ NaOH]

.008 = k x .12 x .12

k = .55555

when concentration of CH₃Br is doubled

rate of reaction = .555555 x [.24] [ .12 ]

= .016 M/s

when concentration of NaOH  is halved

rate of reaction = .555555 x [.12] [ .06 ]

= .004  M/s

when concentration of both CH₃Br and Na OH is made 5 times

rate of reaction = .555555 x .6 x .6

= 0.2 M/s

Calculate the formula mass of Cuso4​
Mandarinka [93]
Answer: 159.61 g/mol

Copper has a molar mass of 63.546 g/mol

Sulfur has a molar mass of 32.065 g/mol

Oxygen has a molar mass of 16 g/mol, multiply by 4 and it is 16 x 4 = 64 g/mol

63.546 + 32.065 + 64 = 159.61 g/mol

You perform an experiment using 8.0 m hcl. And 2.4 m naoh. The experiment calls for 5.0 ml of hcl and 20.0 ml of naoh. How many
Butoxors [25]

Answer:

2.34g of NaCl

Explanation:

HCl(aq) + NaOH(aq) --------> NaCl(aq) + H2O(l)

Number of moles of HCl= 8 × 5/1000= 0.04 moles

Number of moles of NaOH= 2.4 × 20/1000= 0.048 moles

HCl is the limiting reactant

From the balanced reaction equation, 1 mole of HCl produced 58.5g of NaCl

0.04 moles of HCl will produce 0.04 × 58.5 = 2.34g of NaCl

How many of the following atomic particles does a neutral magnesium
VARVARA [1.3K]

Answer:

\boxed{\text{12 p, 12 n, and 12 e}}

Explanation:

No atoms of Mg have a mass of 24.3050 u. That is the average mass of all the isotopes of Mg.

However, the most common isotope of Mg is ₁₂²⁴Mg (mass = 23.99 u)

The atomic number of Mg is 12. It has 12 protons.

The atomic mass of ²⁴Mg is 24. That's the total number of protons and neutrons.

 p + n = 24

12 + n = 24

       n = 12

An atom of ²⁴Mg has 12 neutrons.

If the atom is neutral, the number of electrons equals the number of protons.

e = p = 12

\text{An atom of }$^{24}$\text{Mg contains }\boxed{\textbf{12 p, 12 n, and 12 e}}
