Answer:
Explanation:
Quantity of heat required by 10 gram of ice initially warm it from -5°C to 0°C:
here;
mass, m = 10 g
specific heat capacity of ice, 
change in temperature, 
Amount of heat required to melt the ice at 0°C:
where, 
we know that no. of moles is = (wt. in gram) 
(molecular mass)
Now, the heat required to bring the water to 70°C from 0°C:
specific heat of water, 
change in temperature, 
Therefore the total heat required to warm 10.0 grams of ice at -5.0°C to a temperature of 70.0°C:
The volume of the gas is 180.26 L, if there are 63.5 mol of an ideal gas at 9.11 atm at 42.80 °C.
Applying the ideal gas law PV= nRT
After rearranging the aforementioned expression, the volume might then be found as: V= n R T/ P.
Consequently, V= 63.5 mol, 0.0821, 315 K, and 9.11 atm equal 180.26 L.
<h3>How is the ideal gas equation defined?</h3>
The ideal gas equation is PV = nRT. In this equation, P denotes the ideal gas's pressure, V its volume, n its total amount, expressed in moles, and R its resistance for the universal gas constant, and T for temperature.

Answer:
When we waste food, we also waste all the energy and water it takes to grow, harvest, transport, and package it. And if food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide.
Explanation:
H2O is the Bronsted-Lowry acid in the forward reaction, donating an H+ to CH3, and CH4 is the Bronsted-Lowry acid in the reverse direction, donating an H+ to OH-.
there are 1023 atoms in pure aluminium
