Answer:
M is increased loudness
O is decreased loudness
N is decreased pitch
P is increased pitch
Louder soundwaves ten to have longer and deeper waves visa versa.
Increased pitch tends to have shorter soundwaves. visa versa
In the reaction Sn(s) + 2H+(aq) → Sn2+ (aq) + H2(g)
from this reaction, we get that Sn loses from 0 to 2 electrons so it's oxidized So it is the reducing agent.
and H gains from 0 to 1 electrons so, it's reduced so ∴ it is the oxidizing agent
Answer/Explanation:
This electrical energy now travels through the phone supplying the phone with electricity. Batteries in a cell phone supply chemical energy to electric charges. The electric charges use the energy to be put into motion.
<h3><u>Answer</u>;</h3>
D. All polysaccharides are made up of carbon, hydrogen, and oxygen.
<h3><u>Explanation</u>;</h3>
- A polysaccharide is a large molecule made of many monomers called monosaccharides such as glucose, galactose, fructose, etc.
- Polysaccharides can be homopolysaccharides, where all monosaccharides are the same or heteropolysaccharide in which the monosaccharides vary.
- They may be linear, where a molecule of polysaccharides has straight chain of monosaccharides, or branched polysaccharides in which a chain has arms.
- <em><u>All polysaccharides contain oxygen, hydrogen and carbon atoms like all the carbohydrates.</u></em>
