Answer:
1.6896 grams
Explanation:
Given that:
Total pressure = The pressure of 
+ partial pressure of 
∴
The pressure of = Total pressure - partial pressure of
= (754.8 - 17.55) mmHg
= 737.25 mmHg
At standard conditions:
1 mmHg = 0.00131579 atm
∴
737.25 mmHg will be: (737.25*0.00131579) atm = 0.970065928 atm
P ≅ 0.97 atm
The temperature (T) = 293 K
Volume (V) = 1.31 L
Using ideal gas equation
PV = nRT
0.97 × 1.31 = n × 0.0821 × 293
n = 0.0528
mass of oxygen = no. of moles * molar mass
= 0.0528 * 32
= 1.6896 grams
C. Sap- appareently i have to use 20 characters so im just gonna keep typing lol
Answer: B. proliferation phase
Explanation:
The proliferative phase is one of the stage of wound healing. This is a phase in which new tissues rebuilt over the injury to heal it. The tissues are made up of collagen.
In the proliferative phase the injury contracts and the skin becomes stiff, the muscles becomes rigid thus the body require optimal time to begin the therapeutic exercise. The exercise will improve the motion and flexibility of the body. The new network of blood vessels will cause the granulation of the tissues and provide sufficient nutrients and oxygen for recovery.
Answer:
Magnesium is in Group II and has two electrons in its valence shell. Thus it tends to lose two electrons. It wants to be a stable and it is easier for it to lose two electrons than gain 6.
Explanation:
Physical Quantities are those quantities that can be measured, either directly or indirectly.
Example : the SPEED of light, MASS of Earth, TEMPERATURE of the Sun, LENGTH of the cardboard, FORCE, TORQUE, etc
(The quantities in bold are physical ones)
Non- Physical Quantities are those which cannot be measured directly or indirectly.
Example : Your LOVE, basically all the feelings
