C2h2+ 2h2 = c2h6
Hydroge oxygen +ho4 c2+carbon oxygen
v1= initial volume c1= initial concentration v2= final volume c2= final concentration For example, you have 10mL of an unknown substance with a concentration of 0,5mol/L. If you add 50mL, what will the final concentration be. V1= 10mL C1= 0,5mol/L V2= 60mL C2= x 10/0,5=60/x You must start by putting everything in the same mesure. We'll use mL here. So 0,5-->1000mL= 50-->10mL 50x60= 300 300/10= 30 30 is your C2
That would be combustion with the products being carbon dioxide and water (assuming complete combustion) and a release of energy.
You don't!! That is an impossible reaction as written. Message me if you have the correct reaction soon.
The conservation of energy tells us that energy before the collision equals energy the comes out of the system after the collision. In the case of a stationary target nuclei and a neutron beam we have as our initial energy Rest mass (E - mc2) of the nuclei and the particle in the beam. Kinetic energy of the nuclei and the neutron projectile. So the initial energy looks like KEn + mn*c2 + KEnuc + mnuc*c2 We note that the initial KE of the stationary nucleus is zero and omit this term. KEn + mn*c2 + mnuc*c2 Assuming neutron absorption (i.e. only 1 particle) all of the energies after the collision are described by KEnuc_f + mnic_f*c2 Use the principle of conservation of energy to set the two equal to one another. KEn + mn*c2 + mnuc*c2 = KEnuc_f + mnic_f*c2 Now solve for the final KE of the combined nuclei, KEnuc_f KEnuc_f = (KEn + mn*c2 + mnuc*c2) - (mnic_f*c2) This is the recoil energy.
a2
l a2 b2 is c2!!Its completely norma
Pythagorean Theorem
a right triangle
52+32 = c2 34 = c2 c = the square root of 34
a2+b2+c2=x2+y2+z2 divide each side by 2 (a2+b2+c2)/2=(x2+y2+z2)/2 a+b+c=x+y+z
12c
You just typed it.
All you need to do is substitute the given values of a and c into the equation, then solve for c: a2 + c2 = b2 102 + 302 = b2 100 + 900 = b2 b2 = 1000 b = √1000 b = 10√10
* a2 + b2 = c2 * a = 3 * b = 8 * (3)2 + (8)2 = c2 * 9 + 64 = c2 * 73 = c2 * c = √73
c= -2 2/7 OR -2.285714
a2+b2 = c2 92+52 = c2 81+25 = c2 106 = c2 Square root both sides to find the value of c: c = the square root of 106 => 10.29563014
