C) medium.
The medium of a wave is any substance that carries the wave, or through which the wave travels.Ocean waves are carried by water, sound waves are carried by air, and. the seismic waves of an earthquake are carried by rock and soil.
Starch is present in two forms- Amylose- which is linear chain of glucose and Amylopectin is a branched chain polymer of glucose.glycogen is found in animals and is stored in liver.
Answer:
From the general gas lawa
PV/T=k---constant
Phase 1
735×1.2/385K=2.3
Phase 2
K(constant)×T/P
2.3×290/651
Volume=1.0246dm³
The balanced chemical reaction is expressed as:
<span>2Al(s)+3Cl2(g)→2AlCl3(s)
To determine the volume of chlorine gas needed given the mass of aluminum metal to be used, we need to calculate for the moles of chlorine needed and use a relation that relates moles and volume by assuming the gas to be an ideal gas. We use the equation PV =nRT. We calculate as follows:
7.85 g Al ( 1 mol / 26.98 g ) ( 3 mol Cl2 / 2 mol Al ) = 0.43643 mol Cl2
PV = nRT
V = nRT / P
V = 0.43643 (0.08205) (298) / (225/760)
V = 36.04 L chlorine gas
The minimum volume needed would be 36.04 L.</span>
For the given HCl ionization reaction in aqueous medium,
the following statements are true:
-water, H₂O, uses a lone pair of electrons to form a new covalent bond with H⁺
-Typically a covalent bond is broken when acid donates an H⁺
-When the H-Cl bond breaks, the bonding pair of electrons remains with Cl.
