Hydrogen and oxygen react under a specific set of conditions to produce water according to the equation: 2H2(g)+O2(g) -> 2H2O(g)
I think, but i hope this helps :)
Answer:
im pretty sure its 1 mole of sugar
Explanation:
2.05 oz (58.45 g) of salt and 11.98 oz (342.3 g) of sugar
The amount of heat required to change the sample from ice at -45.0°C to liquid water at 75.0°C is 83.8 kJ.
<h3>
Quantity heat required to convert the ice to liquid</h3>
The total quantity of heat required is calculated as follows;
q(tot) = q1(to ice) + q2(fusion of ice) + q3(liquid)
q(tot) = mcΔθ₁ + mΔHf + mcΔθ₂
q(tot) = (100)(4.2)(0 - -45) + (334)(100) + (100)(4.2)(75 - 0)
q(tot) = 18,900 J + 33,400 J + 31,500 J
q(tot) = 18.900 kJ + 33.400 kJ + 31.500 kJ
q(tot) = 83,800 J = 83.8 kJ
Thus, the amount of heat required to change the sample from ice at -45.0°C to liquid water at 75.0°C is 83.8 kJ.

Answer:
They all have molecules in motion,
you may not think this about solids but the molecules are packed so closely together there is no room to get past each other.
for a liquid the molecules are packed densely but are loosely place, giving them the space to slip past each other, making it possible to form to what ever the liquid is in.
for gas the molecules are not packed so loosely that it is not a definable shape, but can be compressed
