Answer:
From the periodic table:
mass of carbon = 12 grams
mass of hydrogen = 1 grams
mass of oxygen = 16 grams
molar mass of surcose = 12(12) + 22(1) + 11(16) = 342 grams
number of molecules = number of moles x Avogadro's number
number of moles = number of molecules / Avogadro's number
number of moles = (2.2x10^17) / (6.02x10^23) = 3.6544 x 10^-7 moles
number of moles = mass / molar mass
mass = number of moles x molar mass
= 1.7 x 10^17/6.022 x 10^23.
Answer: option (1) decreases.
Explanation:
May be you have experienced that: when you go to the beach, where the atmposhpere pressure is greater than the atmosphere pressure in places that are at higher altitudes, the water takes longer to boil. That is because the boiling temperature is greater, and you need more total heat (more time) to permit the liquid to reach that temperature.
The reason why that happens is because substances boil when the vapor pressure (the pressure of the particles of vapor over the liquid) equals the atmosphere pressure. So, when the atmposhere pressure increases, the temperature at which the vapor pressure reaches the atmosphere pressure also increases, and when the atmosphere pressure decreases, the temperature at which the vapor pressure reaches the atmosphere pressure decreases.
The forelimb
Explanation:
The skeletal system is made up of the bones of the human body which provides protection for vital organs in the body. It also serve as a surface for the attachment of muscles through which movement is coordinated.
There are different bones in the body.
The forelimb is made up of the:
- Scapula
- Humerus
- Ulna
- Radius
- Carpals
- Metacarpals
These bones are jointed together to form our arm. If an archaeologists digs up any of the bones, he/she has unraveled some of the bones of the forelimb.

Answer: A loss of the ion concentration gradient that drives this process.
Explanation:Ouabain known as g-strophanthin, is a cardiac glycoside that can be medically used to treat hypotension.It acts by nhibiting the sodium - potassium (Na/K-ATPase) by causing a loss of the ion concentration gradient that drives it's process. Originally, it was a toxic plant that was used as an arrow poison in eastern Africa for hunting and warfare. Recently, Ouabain is synthesized by animals and secreted from the adrenal cortex to regulate body osmosis.
Answer:
The answer to your question is:
Explanation:
1) Increasing atomic radius:
Oxygen 74
Aluminum 143
Potasium 227
2) Increasing electronegativity
Neon -
Aluminum 1.61
Sulfur 2.58
Oxygen 3.44
3.-
Electronegativity: is the measure of the tendency of an atom to attract a pair of electrons.
Ionization energy: is the quantity of energy that an isolated, gaseous atom must absorb to discharged an electron, resulting in a cation.
4.-
Atomic radius increases as we move down on the periodic table.
Atomic radius is the distance from the center of a nucleus to the outer most shell containing electrons.
5.-
Sulfur = 1s² 2s² 2p⁶ 3s² 3p⁴
Neon = 1s² 2s² 2p⁶
