Assuming that the circuit is a simple series circuit we can determine what the current is through the circuit by using the basic relationship of
V = IR
I = V/R = 60 V/12 ohms = 5 Amperes
The current in the circuit is 5 A.
Answer:
Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M
Explanation:
Considering
Given that:
So,
<u>Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M</u>
Answer:
Explanation:
Given: Entropy of surrounding: ΔSsurr = ?
Temperature: T= 355 K
The change in enthalpy of reaction: ΔH = -114 kJ
Pressure: P = constant
As we know, ΔH = -114 kJ ⇒ negative
Therefore, the given reaction is an exothermic reaction
Therefore, Entropy of surrounding at <em>constant pressure</em> is given by,
<u><em>In the given reaction:</em></u>
2NO(g) + O₂(g) → 2NO₂(g)
As, the number of moles of gaseous products is less than the number of moles of gaseous reactants.
As we know, <em>for a spontaneous process, that the total entropy should be positive.</em>
<u>Therefore, at the given temperature,</u>
- if then the given reaction is spontaneous
- if then the given reaction is non-spontaneous
Answer:
Not much heat moves into the lower levels of the ground. The heat that the ocean absorbs is mixed with the lower water quickly. ... At night, while the land cools off quickly, the water at the surface is kept warmer because the water is mixed around with the warmer water underneath.
Astatine is At in the periodic table, hope I helped :))
