Explanation:
here are your dissolutions
Answer:
gas
Explanation:
the liquid evaporates and has heat is given to the particles, their kinetic energy increases and they bounce off one another
CO because it is the chemical symbol for the element cobalt whereas the rest are compound. H20 is water, CO2 is carbon dioxide and N2 is dinitrogen.
Answer:
5.75 L.
Explanation:
From the question given above, the following data were obtained:
Rate = 54.1 miles/gallons
Distance = 132 km
Volume (in L) consumed =?
Next, we shall convert 132 km to mile. This can be obtained as follow:
1 km = 0.621 mile
Therefore,
132 km = 132 km × 0.621 mile / 1 km
132 km = 81.972 mile
Next, we shall determine the volume (in gallons) of the gas needed. This can be obtained as follow:
Rate = 54.1 miles/gallons
Distance = 81.972 mile
Volume (in gallon) =?
Rate = Distance / volume
54.1 = 81.972 / volume
Cross multiply
54.1 × volume = 81.972
Divide both side by 54.1
Volume = 81.972 / 54.1
Volume = 1.52 gallon.
Finally, we shall convert 1.52 gallon to litre (L). This can be obtained as follow:
1 gallon = 3.785 L
Therefore,
1.52 gallon = 1.52 gallon × 3.785 L / 1 gallon
1.52 gallon = 5.75 L
Therefore, 5.75 L of the gas will be consumed.
202.50 ml is the maximum volume of 0.240 M HCl that can be added to the buffer before its buffering capacity is lost.
Explanation:
Data given:
volume of buffer = 135 ml or 0.135 litres
molarity of the buffer = 0.360 M
volume of the acid = ?
molarity of the acid = 0.24 M
the number of moles of conjugate base is
M X V = number of moles
0.360 X 0.135
0.0486 moles of conjugate base
The maximum amount of acid added will equal the amount of conjugate base from the buffer.
So, the volume of acid will be calculated by using the formula:
Molarity =
volume =
= 0.2025 l
202.50 ml is the volume of acid added.
