2Ag + (aq) + 2NO3 (aq) + Ba2 + (aq) + 2OH - (aq) --> Ba2 + (aq) + 2NO3 (aq) + 2AgOH (s)
cancel out spectator ions
2Ag + (aq) + 2OH --> 2AgOH (s)
hope this help
The wood has undergone a chemical change and has been transfered into energy and gas. Also, the smoke coming from the fire comes from the wood
Answer:
191 °C
Explanation:
We'll begin by calculating the number of mole in 88.0 g of Ne. This can be obtained as follow;
Mass of Ne = 88.0 g
Molar mass of Ne = 20 g/mol
Mole of Ne =?
Mole = mass /molar mass
Mole of Ne = 88 / 20
Mole of Ne = 4.4 moles
Next, we shall determine the temperature. This can be obtained as follow:
Mole of Ne = 4.4 moles
Pressure (P) = 350 KPa
Volume (V) = 48.5 L
Gas constant (R) = 8.314 KPa.L/Kmol
Temperature (T) =?
PV = nRT
350 × 48.5 = 4.4 × 8.314 × T
16975 = 36.5816 × T
Divide both side by 36.5816
T = 16975 / 36.5816
T = 464 K
Finally, we shall convert 464 K to celsius temperature. This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 464 K
T(°C) = 464 – 273
T(°C) = 191 °C
Thus, the temperature is 191 °C
Answer:
The valency of Aluminium (Al) is +3 whereas, the valency of Chlorine is -1.
Explanation:
Valency is not defined for a compound. It is only for elements. Basically, valency is the combining or replacing power of an hydrogen atom of a certain element with an other atom of element.
