Answer:
Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M
Explanation:
Considering
Given that:
So,
<u>Molarity of NaCl = Molarity of sodium ions = Molarity of chloride ions = 0.01 M</u>
<h2>Answer:</h2>
The correct answer is option D which is substances will pass in and out of the cell in an uncontrolled manner.
<h3>Explanation:</h3>
- Cell membrane is outer organelle in the cell, it is responsible for the transport of materials into and out to the cell through osmosis and active transport.
- In the absence of the cell membrane, there will not be control of transport of a materials to the cell.
- Energy production is the task of mitochondria and food storage is the function of vacuoles.
- Photosynthesis takes place on the chloroplasts.
Answer:
b. aluminum
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of 1g of a material in 1°C.
Thus, the sample with the higher specific heat capacity is the sample that will require more energy to increase its temperature in 1°C, suffering the smallest change in temperature.
Thus, is the aluminium with 0.900J/gK the element that is most likely to undergo the smallest change in temperature:
<h3>b. aluminum
</h3>
Chemical changes are permanent and alter the identity of a sustance
