UV rays and X-rays are electromagnetic waves (do not require material medium for transmission). They are part of the electromagnetic spectrum and travel with the speed of light (3×10^8 m/s). In this case i believe the answer is C, X-rays have a higher frequency compared to UV rays.
Answer:
In physics, a region in which each point is affected by a force. The strength of a field, or the forces in a particular region, can be represented by field lines; the closer the lines, the stronger the forces in that part of the field. See also electromagnetic field.
Answer:
The symbol that represent a salt is CaCl2
Explanation:
The CaCI2 is the calcium chloride that an organic compound now a salt having a chemical formula i.e. CaCI2. Also it is non-color cyrstalline solid at the room temperature also it is highly soluble in the water
Therefore as per the given situation the symbol that represent a salt is CaCI2
This is the answer and the same is not provided in the given options
I believe it would be 1.660539040 × 10−24 gram.
Answer:
There are produced 6.72 g
Explanation:
This is the reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
1 mol of glucose reacts with 6 moles of oxygen, to make 6 moles of dioxide and 6 moles of water
Molar mass of CO₂ = 46 g/m
Moles CO₂ = 10.3 g/ 46g/m = 0.224 moles
Ratio is 6:1
6 moles of CO₂ are made from 1 mol of glucose
0.224 moles of CO₂ are made from (0.224 . 1)/6 = 0.0373 moles of glucose
Molar mass glucose = 180.15 g/m
Mass glucose = moles . molar mass
0.0373 m . 180.15 g/m = 6.72 g
