(ANS1)— P4 + 5O2 ---> 2P2O5
(ANS2)— C3H8 + 5O2---> 3CO2 + 4H20
(ANS3)— Ca2Si + 4Cl2 ---> 2CaCl2 + SiCl4
It seems that you have missed the necessary options for us to answer this question so I had to look for it. But anyway, here is the answer. If Dr. John Sutherland is correct, the one that was necessary <span> for inert carbon atoms to become part of the chemistry of earth is CYANIDE. Hope this helps.</span>
Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
Answer:
A
Explanation:
Chlorine has one valence electron
Hence one chlorine atom reacts with 2 atoms of lithium
And also reacts with 3 atoms of boron
Use Planck's equation (E=hv) to solve. where <span>frequency (v) of ultrviolet radiation is 6.8 × 1015 1/s. </span><span>
</span>The variable h is a
constant equal to 6.63 × 10-34 J·s
E= <span>(6.8 × 1015 1/s)x(</span>6.63 × 10-34 J·s)
