Answer:
578.04 °C
Explanation:
The temperature is given in Kelvin which has value = 304.89 K
Kelvin and Celsius are both units of the temperature which can be incontrovertible.
The conversion of T(K) to T( °C) is shown below:
T( °C) = T(K) - 273.15
Given that = T(K) = 304.89
So,
T = (304.89 + 273.15) °C = 578.04 °C
<u>The temperature in degrees Celsius is 578.04 °C . </u>
Answer:
Yes is possible
Explanation:
MnSO4*7H2O(s) → MnSO4(s) + 7H2O(g)
This should be an endothermic reaction. The water molecules are interacting with the Mn2+ and SO42- ions within the crystal lattice of the compound. You must overcome those interactions, and so that would require the input of energy.
60+68=128
128/2=64
so the answer is 64

Answer:
545
Explanation:
If we let the unknown temperature in Kelvin be x,
Lewis Structures of Ammonium Ion (RED) and Chloride Ions (BLUE) are attached below.
Lewis structures are those structures which shows the environment of electrons in a molecule. These structures basically depicts the bonding electrons and non-bonding electrons also known as Lone pair electrons.
In attached structure it can be seen that the ammonium ion is made when nitrogen atom is forming four single bonds with four hydrogen atoms and the formal charge on nitrogen becomes +1. While, in case of chloride ion the chlorine atom has four lone pair of electrons and has a formal charge of -1.
