The dilution formula can be used to find the volume needed
c1v1 = c2v2
Where c1 is concentration and v1 is volume of the concentrated solution
And c2 is concentration and v2 is volume of the diluted solution to be prepared
c1 - 0.33 M
c2 - 0.025 M
v2 - 25 mL
Substituting these values in the equation
0.33 M x v1 = 0.025 M x 25 mL
v1 = 1.89 mL
Therefore 1.89 mL of the 0.33 M solution needs to be diluted up to 25 mL to make a 0.025 M solution
Answer:
of heat energy will be released
Explanation:
Balanced reaction-
According to balanced equation, moles of produces 1 mol of to release 46.17 kJ of heat.
Molar mass of = 2.016 g/mol
Number of moles = (mass)/(molar mass)
So, 28 kg of = 28000 g of
= moles of
= moles of
So. moles of react to release heat or of heat
I can’t see it can you write the problem ?
Answer:
combination, decomposition, single-replacement, double-replacement, and combustion.
Explanation:
Answer:
The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
Explanation:
Answer shortly is two electrons and a hydrogen ion
