Answer:
Blood enters the right atrium and passes through the right ventricle.
Explanation:
The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart.
The process of watering the crops is called irrigation.
Any two methods of irrigation are:
<h3>(i) Sprinkler system:</h3>
This system is used on the uneven land where less water is available. The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. Water is allowed to flow through main pipe under pressure, which escapes from the rotating nozzles. In this way water gets sprinkled on the crop.
<h3> (ii) Drip irrigation:</h3>
This system is used to save water as it allows the water to flow drop by drop at the roots of the plants. It is the best technique for watering fruit plants, gardens and trees. Water is not wasted at all.
<span>CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair.</span>
Main Answer: The standard electrode potential of galvanic cell constructed from barium and manganese electrode is 4.097.
Explanation:
When the galvanic cell constructed between Manganese and Barium, the half reactions will be as follows:
Mn2+(aq) + 2e-⟶ Mn(s) E1 = −1.185
Ba2+(aq) + 2e-⟶ Ba(s) E2 = −2.912
By considering the above two reactions, the standard electrode potential can be calculated.
The galvanic cell standard electrode potential is given by E1 + E2 = 1.185 + 2.912 = 4.097 volts
What is standard electrode potential?
Standard electrode potential is defined as the measure of reducing power of any compound or element. Its units are volts.
