We have to complete all the given reactions.

1. Fe(s) + CuCl₂ → Cu + FeCl₂

2. Cu(s) + FeCl₂(aq)  → NR (no reaction takes place)

3. K(s) + NiBr2(aq) → NR (no reaction takes place)

4. Ni(s) + KBr(aq) → K + NiBr₂

5. Zn(s) + Ca(NO₃)₂(aq) → NR (no reaction)

6. Ca(s) + Zn(NO₃)₂(aq) → Zn(s) + Ca(NO₃)₂(aq)

Under the gold standard, a country in balance-of-trade equilibrium earns income from exports that is equal to the money its resi
solong [7]

The answer is true.

Explanation:

The balance of trade is nothing but the country's exports minus the country's imports.

Exports means, what you produce in the country and sell it to other countries, whereas imports means what you get or buy from the other countries.

When you export more than you import, you have trade surplus .In that case the income from exports are more than the money spent. So you have a trade surplus.

When you import then you have a trade deficit or your income is low. Most of the countries want a trade surplus.

But when the Income from exports and the money spent on imports are the same , the situation is that of balance of trade equilibrium, where the income from exports is equal to the money its residents pay for the imports.

Five pulses are generated every 0.112 s in a tank of water. What is the speed of propagation of the wave if the wavelength of th
DedPeter [7]

Answer:

The answer to the question is

The wave speed is 53.57 cm/s

Explanation:

The speed of a wave is the distance covered by the wave per unit time.

Wave speed is given by

v = f×λ

where v = The velocity of the wave

f = The wave frequency

λ = The wavelength of the wave

the speed v of the wave can also be expressed interms of the period as

v = λ/T

The freuency of the given wave is f = 5/(0.112 s) = 44.64 Hz and the wavelength is λ = 1.20 cm

Therefore the speed of the wave = 44.64 Hz × 1.20 cm = 53.57 cm/s
