Answer:
Energy is converted in a hydroelectric plant as follows;
The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy
Explanation:
The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine
The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;
The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.
Answer: the picture is work for number 1,2,4,5,7
Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.
number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.
hope this helps :))
A precipitation reaction is a reaction that yields an insoluble product.
When two solutions which could react are mixed together, they interact with each other and products are formed. These products could be aqueous solutions or solids.
When a mixture of two aqueous solutions react chemically to yield an insoluble product, we can say that a precipitation reaction has taken place.
We shall now proceed to fill in the missing products in each of the reactions;
a) Ca(NO3)2 (aq) + CuSO4 (aq) → CaSO4(s) + Cu(NO3)2 (aq)
b) 2KC2H302 (aq) + COSO4 (aq) → Co(C2H302)2 (s) + K2SO4(aq)
c) 2K3PO4 (aq) + 3Mg12 (aq) → 6KI(aq) + Mg3(PO4)2 (s)
d) FeCl3 (aq) + 3NH4OH (aq) → Fe(OH)3 (s) + 3NH4Cl(aq)
