Explanation:
C₄H₈O₂ C₂H₄O
C₄H₁₂O₄ CH₃O
C₂H₁₀O₂ CH₅O
The empirical formula is that which expresses the composition of a compound in the simplest whole number ratio of the atoms of the different elements that makes up a compound.
The molecular formula is the true formula of the compound. It expresses the actual number of moles of atoms of the different elements present in a molecule of the compound.
C₄H₈O₂ C₂H₄O
4: 8 : 2 divided by 2 gives 2: 4 : 1
C₄H₁₂O₄ CH₃O
4: 12: 4 divided by 3 gives 1: 3: 1
C₂H₁₀O₂ CH₅O
2: 10: 2 divided by 2 gives 1: 5: 1

Answer:
asexual cell
Explanation:there are mainly 2 types sexual and asexual i would say asexual because they grow without another parent and don't have a nucleus.
Blood is considered a suspension because it contains particles that can settle out.
A (heterogeneous) suspension is defined as a mixture between a liquid and particles of a solid. In the case, the particles do not dissolve. The particles and the liquid are mixed up so that the particles are dispersed throughout the liquid. They are "suspended" in the liquid. A key characteristic of a suspension is that the solid particles will settle and separate over time if left alone.
This is exactly what happens when anti-coagulated blood is left to stand alone for some time. Blood cells separate and settle from the plasma, the watery part of the blood.
Answer:
copper will reach to higher temperature first.
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
The substances with higher value of specific heat capacity require more heat to raise the temperature by one degree as compared the substances having low value of specific heat capacity.For example,
The specific heat capacity of copper is 0.386 j/g. K and for aluminium is 0.900 j/g.K. So, aluminium take a time to increase its temperature by one degree by absorbing more heat while copper will heat up faster by absorbing less amount of heat.
Consider that both copper and aluminium have same mass of 5g and change in temperature is 15 K. Thus amount of heat thy absorbed to raise the temperature is,
For copper:
Q = m.c. ΔT
Q = 5 g× 0.386 j/g K × 15 K
Q = 28.95 j
For aluminium:
Q = m.c. ΔT
Q = 5 g× 0.900 j/g K × 15 K
Q = 67.5 j
we can observe that aluminium require more heat which is 67.5 j to increase its temperature. So it will reach to higher temperature later as compared to copper.
