Mayonnaise is a heterogeneous mix. The correct answer is colloids.
Answer: There are five significant figures in 865,010.
Explanation:
When a degree of accuracy is stated by each digit present in a mathematical figure then it is called a significant figure.
Rules for counting significant figures is as follows.
- Any non-zero digits and zeros present between a non-zero figure are counted. For example, 3580009 has seven significant figures.
- Trailing zeros are counted in a non-zero figure. For example, 0.00250 has three significant figures.
- Leading zeros are not counted. For example, 0.0025 has two significant figures.
So, in the given figure 865010 has five significant figures and the trailing zero will not be counted.
Thus, we can conclude that there are five significant figures in 865,010.
Answer:I think it’s mechanical energy
Explanation:
Answer:
C. Energy is absorbed and released during chemical reactions,
Explanation:
All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy.
Answer:
Increases
Explanation:
As the number of carbons in the hydrocarbon increases, the boiling point of increases and volatility reduces.
The increasing number of carbon atoms increases the molecular mass and this will eventually lead to a higher boiling point.
- With increasing chain length, hydrocarbons tends towards liquid and solid phases.
- This increase leads to a greater intermolecular interaction in the compound.
- Intermolecular forces determines the boiling point of hydrocarbons.
- This is why gasoline is easily combusted compared to lubricant oil.
