Answer:
Moment=Force x Pivot
Explanation:
A moment is the turning effect of a force. Moments act about a point in a clockwise or anticlockwise direction.
Law of moments:
When an object is balanced (in equilibrium) the sum of the clockwise moments is equal to the sum of the anticlockwise moments.
How to calculate moments:
Moment=Force x Pivot
Answer:
Enthalpy change is 6007 J
Entropy change is
Gibb's free energy change is 0 J.
Explanation:
From the given,
The enthalpy change for the melting of ice =
Temperature =
Let's convert the temperature centigrade into Kelvin.
Number of moles of ice = 1.00 mol
Enthalpy change of 1.00 mol temperature
Therefore, Enthalpy change () for the melting of 1.00 mole of ice at temperature is 6007 J.
Entropy change for the melting of 1.00 mole of ice at :
Therefore, Entropy change() for the melting of 1.00 mole of ice at temperature is .
The Gibb's free energy change is expressed by the following formula.
Therefore, Gibb's free enrgy change () for the melting of 1.00 mole of ice at temperature is
A.
These are characteristics of viruses.
Answer:
Yes
Explanation:
If Mg + 2HCI is Blanced then MgCI2 + H2 is also Blanced . So yes
