I think you mean:
".. reacts with oxygen gas to produce lead (II) oxide and 'sulfur' dioxide..."
The balanced chemical reaction would be
2PbS + 3O2 --> 2PbO + 2SO2
The stiochiometric ratio is this: 3 moles of O2 produces 2 moles of lead (II) oxide. So,
0.500 moles (2/3) = 0.333 moles
Therefore, 0.333 moles of PbO is produced when 0.500 moles of O2 reacts with PbS.
Answer:
the basic difference btw alkane and alkene is the presence of single and double bond respectively.first is saturated hydrocarbon while the latter is unsaturated
Hope this helps you buddy!!
Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
Some of the properties that will change as the biological membrane composed primarily of phospholipids change from the saturated to unsaturated fatty acid tails of the phospholipid would include, permeability of the membrane, this will cause the membrane to be more fluid and not remain as controlling of the materials. The membrane will ultimately become poor in regulating ions and other materials from coming into the cell, as the phospholipids are not tightly packed due to them being unsaturated and having carbon double bonds within them. This can also affect the overall shape of the plasma membrane as well, causing it to be not as structured, and more fluid,
Our weight on the moon is less than it would be on earth due to a different of the strength of gravity on the moon
