Answer:
Explanation:
Kindly answer the way I have written.
Answer:
As you go down a group on the periodic table, you get more electron shells and therefore a larger atomic radius.
Explanation:
Net ionic between HCl and the buffer equation
CH3COOH --> acetic acid, CH3COO- acetate , H+ proton from HCl
there is neutralization of the acetate, and an increase in acid
the ionic equation
CH3COO-(aq) + H+(aq) + Cl-(aq) --> CH3COOH(aq) + Cl-(aq)
Net ionic:
CH3COO-(aq) + H+(aq) --> CH3COOH(aq).
Energy is supplied to aluminium to raise the temperature of aluminium.
we can use the following equation to calculate the mass of aluminium
H = mcΔt
H - heat energy supplied
m - mass of material
c - specific heat capacity of aluminium
Δt - change in temperature - 35 °C - 15 °C = 20 °C
substituting the values in the equation
216 J = m x 0.90 J°C⁻¹g⁻¹ x 20 °C
m = 12 g
mass of aluminium is 12 g
Answer:
is the change in enthalpy associated with the combustion of 530 g of methane.
Explanation:
Mass of methane burnt = 530 g
Moles of methane burnt = 
Energy released on combustion of 1 mole of methane = -890.8 kJ/mol
Energy released on combustion of 33.125 moles of methane :
is the change in enthalpy associated with the combustion of 530 g of methane.
