Calculate the mass of oxygen in 30 g of CH NH COOH?​

Chemistry
1 answer:
Naya [18.7K]3 years ago
7 0

Molar mass of CH2NH2COOH - 75

Given mass of CH2NH2COOH - 30

Moles of CH2NH2COOH = Given mass/ Molar mass

moles of CH2NH2COOH = 30/75 = 0.4 mol

One mole of CH2NH2COOH contains 32 gram of oxygen

0.4 mole of CH2NH2COOH will contain = 0.4 × 32= 12.8 g of oxygen

Answer- the mass of oxygen in 30 g of CH2NH2COOH is 12.8 gram!

Which statement is NOT true of molecular orbitals: Select one
trapecia [35]

Answer:

A: Antibonding molecular orbitals are higher in energy than all of the bonding molecular orbitals.

Explanation:

Molecular  orbital theory describes <u>covalent bonds in terms of molecular orbitals</u>, which  result from interaction of the atomic orbitals of the bonding atoms and are associated  with the entire molecule.

A bonding molecular orbital has lower  energy and greater stability than the atomic orbitals from which it was formed. An  antibonding molecular orbital has higher energy and lower stability than the  atomic orbitals from which it was formed.

Electrons in the antibonding molecular orbital have  higher energy (and less stability) than they would have in the isolated atoms. On the  other hand, electrons in the bonding molecular orbital have less energy (and hence  greater stability) than they would have in the isolated atoms.

A certain first-order reaction (a→products) has a rate constant of 9.60×10−3 s−1 at 45 ∘c. how many minutes does it take for the
Alexxandr [17]

The integrated rate law expression for a first order reaction is

ln\frac{[A_{0}]}{[A_{t}]}=kt

where

[A0]=100

[At]=6.25

[6.25% of 100 = 6.25]

k = 9.60X10⁻³s⁻¹

Putting values

ln\frac{100}{6.25}=9.6X10^{-3}t

taking log of 100/6.25

100/6.25 = 16

ln(16) = 2.7726

Time = 2.7726 / 0.0096 = 288.81  seconds
