Fermentation that causes dough to rise is alcoholic acid, and this is when the alcohol is rising and leaving the dough. In a human, we don't have alcohol, or else we would be drunk after we work out. Instead, we have Lactic Acid fermentation, and this is when you use up too much oxygen, so fermentation make us really tired or else, we wouldn't be able to keep working out.
Smashing a rock is the right answer :)
Answer:
Molarity = 8.89 mol/L
Explanation:
Given data:
Mass of hydrogen peroxide = 3%
Density = 1.01 g/mol
Molarity = ?
Solution:
3% hydrogen peroxide means 3 g of H₂O₂ are present in 100 g of solution.
Now we will calculate the moles of H₂O₂.
Number of moles = mass / molar mass
Number of moles = 3g/ 34 g/mol
Number of moles = 0.88 mol
Now we calculate the volume of solution.
d = m/v
v = m/ d
v= 100 g/ 1.01 g/ mL
v = 99 mL
In Litter
v = 99 / 1000 = 0.099 L
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.88 mol/ 0.099 L
Molarity = 8.89 mol/L
<h3><u>Answer</u>;</h3>
Chlorine forms one covalent bond and oxygen forms two covalent bonds
<h3><u>Explanation</u>;</h3>
- Covalent bond is a type of bond the occur when non-metal atoms share electrons. Covalent atom may occur between two atoms in a molecule.
- Diatomic molecule is a molecule consisting of two atoms. Halogens such as chlorine exist as diatomic gases by forming covalent bonds.
- <em><u>Single covalent bond occurs when two atoms held together by sharing a pair of electrons, for example in diatomic molecules such as chlorine.</u></em>
- <em><u>Double covalent bond is a bond that involves two shared pairs of electrons for example in oxygen molecule.</u></em> Triple covalent bond on the other hand is a bond formed by sharing three pairs of electrons between atoms, like in the case of nitrogen molecule.
