Answer:
CH2O and C6H12O6
Explanation:
To find an empirical formula, take a molecular formula and divide the subscript of each element by the greatest common factor of all the subscripts. In this case, the only pair that works is CH2O,C6H12O6, which can be verified by dividing the coefficients of the molecular formula by 6.
Answer:
Yes
Explanation:
One of the top goals of genetic engineering is the improvement of health. Imagine a world without the threat of AIDS or cancer. Those working in the genetics field hope that manipulating the genes of humans will one day enable science to prevent people from contracting these potentially deadly diseases.
Answer:
Two chemicals that can be used to prepare standard solutions in lab are Hydrochloric acid & Sulphuric acid.
Answer:

Explanation:
Assume 100 g of solution.
Then you have 10.0 g of NaCl and 90.0 g of water.

1. Moles of NaCl

2. Kilograms of water

3. Molal concentration

increase the rate of chemical change.
Explanation:
The reaction of the metal oxide with water to form a base in the presence of a spike in temperature will lead to an increase in the rate of chemical change.
Temperature change has considerable effect on reaction rates.
- Temperature is directly proportional to the average kinetic energy of reacting particles.
- Reaction rates varies directly with a spike in temperature.
- It has been known that for every 10°C rise in temperature, above the room temperature, reaction rates become double or tripled.
- Temperature increases the kinetic energy of each of the reacting particles.
- Many of the reacting particles also acquires an energy greater than or equal to the activation energy of the reaction.
- The frequency of ordinary collisions and effective collisions per unit time increases.
