A diversity of scientists is important for reducing bias and for providing different ways of looking at the world. ... To the extent that we can remove our biases and learn from multiple perspectives, we will understand our world better.
Answer:
Selling price of watch A and watch B= Rs. 425
Let cost price of watch A=x
Profit =10%
∴
100
110
x=425
x=386.36
Let cost price of watch B=y
Loss =10%
∴
100
90
y=425
y=472.22
Net cost price =x+y=858.5858
Net selling price =850
Loss%=
858.58
858.5858−850
×100=1%

Answer:
17.3124 grams
Explanation:
Given;
Amount of heat to be produced = 175 kJ
Molar mass of the carbon monoxide = 12 + 16 = 28 grams
Now,
The standard molar enthalpy of carbon monoxide = 283 kJ/mol
Thus,
To produce 175 kJ heat, number of moles of CO required will be
= Amount heat to be produced / standard molar enthalpy of CO
or
= 175 / 283
= 0.6183
Also,
number of moles = Mass / Molar mass
therefore,
0.6183 = Mass / 28
or
Mass of the CO required = 0.6183 × 28 = 17.3124 grams
Benedict's solution is used to test simple sugars, such as glucose. It is blue solution, when sugar is present, it turns to orange / brick red. Depends on the concentration of sugar.
