Conditions such as high pressure and high temperature must occur.
Answer:
The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.
5.27 kJ of heat are required to heat 231 g of gold from 18 °C to 195 °C.
We have 231 g of gold at 18 °C and supply it with heat to increase its temperature to 195 °C. We can calculate the amount of heat required using the following expression.

where,
- <em>c: specific heat capacity of gold</em> (0.129 J/g.°C)
- ΔT: change in the temperature

5.27 kJ of heat are required to heat 231 g of gold from 18 °C to 195 °C.

Answer:
79.3%
Explanation:
Percent yield = 5.33g/6.72g x 100% = 79.3%
The phosphate group contribute the following functional features to the structure of phospholipids:
1. Negative charge to interact with water.
2. Place to attach another small molecule.
The phosphate group is made up of four atoms of oxygen which are attached to one atom of phosphorus. This molecule has a net negative charge of -3. In the phospholipid molecule, the phosphate enhanced the polarity of the phospholipid head by mean of its negative charge which react with water. Phosphate group also provide a point where other small molecules such as alcohol, serine, etc can be attached.
