2NaCl + Br2
This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.
Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.
Hope this helps!
Answer:
When acetylene gas is passed over ammoniacal silver nitrate soln gives white ppt of disilveracetylide is formed. - When acetylene is passed over ammoniacal silver nitrate solution, white ppt of disilveracetylide is formed.
Answer: 581 gmol
0.581 kmol
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1. The conversion for mol to gmol
1 mol = 1 gmol
581 mol=
2. The conversion for mol to kmol
1 mol = 0.001 kmol
581 mol=
3. The conversion for mol to lbmol
1 mol =
581 mol=
I believe it’s an element
Explanation:
Given parameters:
Elastic potential energy = 45J
Extension = 2cm
Unknown:
Spring constant = ?
Solution:
The elastic potential energy exists in any body that can be stretched and will not deformed such as string and a bow.
Elastic P.E = K e²
k is the spring constant
e is the extension
2 cm is the same as 0.02m
45 = x k x 0.02²
k x 0.02² = 90
k = 225000N/m
