Physics
1 answer:
Ugo [173]3 years ago
8 0

Answer:

1) CO2

2) CO2 and CaO

3) MgO

4) H20 and O2

5) CaCl2, CO2, H2O

Explanation:

Now let us try to put down the reactions here;

1) C(s) + O2(g) -------> CO2(g)

2) CaCO3(s) -------> CaO(s) + CO2 (g)

3) 2Mg(s) + O2(g)------> 2MgO

4) 2H2O2(aq) --------> 2H2O(l) + O2(g)

5) CaCO3(s) + 2HCl(aq) ------> CaCl2(aq) + CO2(g) + H2O(l)

Note that a chemical reaction equation is only said to be balanced when the number of atoms of each element on both sides of the reaction equation are exactly the same.

The secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter. The turns ratio of t
Sphinxa [80]

Answer:

The power consumed by the air filter is 9.936 watts      

Explanation:

It is given that, the secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter.

Turn ratio of the transformer, \dfrac{N_s}{N_p}=\dfrac{46}{1}

Voltage of primary coil, V_p=120\ V

Current in the secondary coil, I_s=1.8\times 10^{-3}\ A

The power consumed by the air filter is :

P_s=I_s\times V_s...........(1)

For a transformer, \dfrac{N_s}{N_p}=\dfrac{V_s}{V_p}

So, P_s=I_s\times (\dfrac{N_s}{N_p})\times V_p

P_s=1.8\times 10^{-3}\times (\dfrac{46}{1})\times 120

P_s=9.936\ Watts

So, the power consumed by the air filter is 9.936 watts. Hence, this is the required solution.
