Answer:
3) 2KOH + H2SO4 → K2SO4 + 2H2O
Explanation:
The balanced chemical equation for the reaction of KOH and H2SO4 is,
→ 2KOH + H2SO4 → K2SO4 + 2H2O
Hence, option (3) is the correct answer.
Answer:
chloroplast organelle
Answer. The photosynthesis process takes place in the chloroplast organelle in the growing tissues. As the chlorophyll pigment is available in the chloroplast organelle which is the main photosynthetic pigment, with the help of the molecules they capture the energy of light.
Explanation:
chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
The answer is hyperbaric medicine.
Hyperbaric medicine is a treatment in which is necessary a chamber with
pressure greater than sea level atmospheric pressure. Is intended to reduce the effects of systemic gas bubbles by reducing their size and lead to their
elimination.
Answer: 1.037M
Explanation:
Since the rate constant unit is per seconds, therefore it is a first order reaction.
First order reaction equation is given as
InA= -kt +InAo
Where,Ao is the initial concentration of reactant =0.600M
A is the concentration of reactant at a specifies time t=3×60=180s
and k is the rate constant
InA = -6.50×10^-3 ×180 +In(0.6)
InA = -1.17 + 0.5108
InA= -1.680
A = e-1.680
A= 1.037M
Therefore the concentration after 3minutes is 1.037M
