Answer:
Carbonyl
Explanation:
While the diagram is slightly unclear, the molecule most likely being shown is a carbonyl. A molecule is a carbonyl when there is a carbon double-bonded to an oxygen.
Answer: 4.1 g of barium precipitated.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
Given : moles of barium = 0.030
Molar mass of barium = 137 g/mol
x= 4.1 g
Thus there are 4.1 g of barium that precipitated.
The answer is :
The normal equation for the decomposition of hydrogen peroxide indicates that 2 vol. peroxide vapor should give rise to 2 vol. water vapor and 1 vol. oxygen.
What is hydrogen peroxide ?
- Hydrogen peroxide is water (H2O) with an extra oxygen molecule (H2O2).
- The extra oxygen molecule oxidizes, which is how peroxide gets its power says Dr. Beers.
- This oxidation kills germs and bleaches color from porous surfaces like fabrics.
- Hydrogen peroxide is found in biological systems including the human body.
- Enzymes that use or decompose hydrogen peroxide are classified as peroxidases.
