• Bubbles of a colourless, odourless gas are evolved
• The solution turns red litmus blue
Ca + 2H_2O→ Ca(OH)_2 + H_2
x2=x+2 at x=−1 and x=2 so we have no need to worry about the end-points
f(x)=x+2−x^2
df/dx=1–2x
and that is zero (indicating a maximum) at x=1/2
So the maximum distance is f(1/2)=2.5–0.25=2.25

#SPJ4
Answer: a) 90.5g
b) 33.6 L
Explanation:-
Molar mass of tyrosine
= 181 g/mol
According to Avogadro's law, 1 mole of every substance weighs equal to its molar mass.
1 mole of tyrosine
weighs = 181 g/mol
0.5 moles of tyrosine
weigh 
b) According to Avogadro's law, 1 mole of an ideal gas occupies 22.4 Liters at Standard conditions of temperature and pressure (STP).
1 mole of gas at STP occupy = 22.4 L
1.5 moles of gas at STP occupy =
29.26 gram
Explanation:
No of molecules = no of mole × Avogadro's number
No of molecules = mass in gram/ molar mass × Avogadros number
Mass in gram =No of molecules×molar mass / Avogadros number
Mass in gram = 3.012 ×10^23 × 58.5/6.02×10^23
29.26 gram
Angiosperms didn't exist until the late Mesozoic era..
