Given that the volume of cylinder at STP = 11.2 L
Standard temperature = 273 K
Standard pressure = 1 atm
Calculating the volume of gas at 202.6 kPa and 300. K:
Applying the combined gas law,
= 
Plugging in the values and calculating final volume:
Therefore the correct answer will be, b) 6.15 L
Answer:
By contrast, the red blood cells of mammals lack nuclei and other internal structures found in most animal cells. This simplification allows mammal red blood cells to carry more gas-transporting proteins and to squeeze through smaller blood vessels.
Explanation:
Answer:
Structure has been shown below
Explanation:
- In a Lewis structure, least electronegative atom is taken as central atom (except H)
- Total valence electrons of constituting atoms are used to construct Lewis structure
- A bond between two atoms are represented by a horizontal line or a dotted line (two dots).
- Spatial rearrangement of atoms are neglected in Lewis structure.
- H has one valence electron and O has six valence electrons. So, total valence electrons in
are 8 - Lewis structure of has been given below.
Answer:
(b) matter is lost and energy is released
Explanation:
When atoms are being formed from its constituent components it weighs less this is called mass defect so the answer would be (b) matter is lost and energy is released.
The absorbance reported by the defective instrument was 0.3933.
Absorbance A = - log₁₀ T
Tm = transmittance measured by spectrophotometer
Tm = 0.44
Absorbance reported in this equipment = -log₁₀ (0.44) = 0.35654
True absorbance can be calculated by true transmittance, Tm = T+S(α-T)
S = fraction of stray light = 6%= 6/100 = 0.06
α= 1, ideal case
T = true transmittance of the sample
Tm = T+S(α-T)
now, T= Tm-S/ 1-S = 0.44-0.06/ 1-0.06 = 0.404233
therefore, actual reading measured is A = -log₁₀ T = -log₁₀ (0.404233)
i.e; 0.3933
