Answer:
The other signal that would indicate the presence of a C= C bond appears close to 3100 .
Explanation:
Bands that appear above 3000 are often unsaturation diagnoses suggest. The band at 3000-
3100 is characteristics for C-H stretching frequencies and normally is overlaps with the ones for alkanes because it is a band of weak intensity.
Genes are contained in chromosomes, which are in the cell nucleus.
A chromosome contains hundreds to thousands of genes.
Answer:
Carbon and oxygen are chemically bonded in it.
Explanation:
The other answer choices do not apply for compounds, but rather for mixtures instead.
The synthesis of a compound from its elements in their standard state, accompanied by a change in energy that is known as standard enthalpy of formation of a compound. The standard state of a substance is the most stable physical state of the compound that exist at STP that is at 1 atm, 273 K temperature. So the answer is yes, the energy change accompanying the synthesis of a compound from its elements in their standard state.
Combination reaction also called synthesis reaction, the product will always be a compound.
For example:
A + B -> AB
C2 + O2 -> CO2
H2+Cl2 -> HCl
