Zn(HCO3)2 is the compound for Zinc Bicarbonate
The total mass of the original tissue were from the source which are the pig ovaries. But first, convert 5.6 tons to mg.
5.6 tons × (1000 kg/1 ton) × (1000 g/1kg)×(1000 mg/1g) = 5.6 x 10^9 mg
Thus, the percentage of estrone in the original tissue is
(12.0 mg /5.6 x 10^-9 mg) x 100 = 2.14 x 10^-7 %
When liquid state is being converted to solid state, atoms come closer to each other and their speed of movement also decreases. Instead of moving about in the substance, they are only able to vibrate about their positions in solid. Hence, this change leads to loss of energy. Similarly, atoms loose energy when state changes from gas to liquid.
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance.
Answer:
1.23 × 10³ N
Explanation:
Step 1: Given and required data
- Mass of the person (m): 125 kg
- Acceleration due to the gravitational force (g): 9.81 m/s²
Step 2: Calculate the force acting between the Earth and a 125-kg person standing on the surface of the Earth
We will use Newton's second law of motion.
F = m × g
F = 125 kg × 9.81 m/s²
F = 1.23 × 10³ N
