Consider the molecular structure for linuron, an herbicide, provided in the questions below. How many pi bonds are in the molecu

Sophie [7]

In the herbicide linuron whose structure is shown in the image attached, there are four pi bonds.

A pi bond is formed by a sideways overlap of atomic orbitals. A sigma bond is formed by an end to end or head to head overlap of atomic orbitals. Pi bonds lead to the occurrence of multiple bonds in the molecule.

In the herbicide linuron whose structure is shown in the image attached to this answer, there are four pi bonds which are easily spotted as double bonds in the structure.

A scientist finds one carbon atom for every two oxygen atoms in a sample of compound x. for which other samples of compound x sh

Doss [256]

The formula or chemical formula of a compound is same irrespective of source / mode of synthesis . Thus if a sample of compound has one carbon atom for every two atoms of oxygen (CO2), the formula will remains the same

So the answer is that for all other samples the compound X should hold this ration true.

yan [13]

Answer:

The energy lost by the water is given by:

where

m = 3.0 kg = 3000 g is the mass of water

Cs = 4.179 J/g•°C is the specific heat

is the change in temperature

Substituting,

The energy added to the aluminium is given by:

where

m = 0.30 kg = 300 g is the mass of aluminium

Cs = 0.900 J/g•°C is the specific heat

is the change in temperature

Substituting,

4. 42.9 g

The mass of the water sample is given by

where

is the heat added

is the temperature change

Cs = 4.179 J/g•°C is the specific heat

5. 115.5 J

The heat used to heat the copper is given by:

where

m = 5.0 g is the mass of copper

Cs = 0.385 J/g•°C is the specific heat

is the change in temperature

6. 0.185 J/g•°C

The specific heat of iron is given by:

where

Q = -47 J is the heat released by the iron

m = 10.0 g is the mass of iron
