When we make food, our chemicals in our bodies, cleaning products etc
Hello!! Your atomic mass will be found at the bottom of each element. The atomic mass of Nitrogen is 14.007. Have a great day!!
Option (C) is the correct answer.
When solute is added to the solvent, results in the formation of solution and the process is said to be dissolution.
Dissolution process depends upon the three factors: temperature, stirring and surface area.
Stirring increases the rate of dissolving as when stirring a solute in the solvent, stirring helps in the distribution of solute throughout the solvent which results in speed up the dissolving rate.
Dissolution also depends upon the temperature, in warm solvent, solute dissolves readily whereas in cool solvent, solute dissolves slowly as particles have more movement energy.
Greater the surface area, there will be more contact between the solute particles and solvent particles which increases the rate of dissolving. Smaller the surface are, there will be less contact between the particles which decreases the rate of dissolving. For example: granulated sugar dissolves more readily due to larger surface area and one ice cube dissolves slowly due to smaller surface area.
Hence, rate of dissolution depends upon temperature, stirring, surface area.
Answer:
To understand what science is, just look around you. What do you see? Perhaps, your hand on the mouse, a computer screen, papers, ballpoint pens, the family cat, the sun shining through the window …. Science is, in one sense, our knowledge of all that — all the stuff that is in the universe: from the tiniest subatomic particles in a single atom of the metal in your computer's circuits, to the nuclear reactions that formed the immense ball of gas that is our sun, to the complex chemical interactions and electrical fluctuations within your own body that allow you to read and understand these words. But just as importantly, science is also a reliable process by which we learn about all that stuff in the universe. However, science is different from many other ways of learning because of the way it is done. Science relies on testing ideas with evidence gathered from the natural world. This website will help you learn more about science as a process of learning about the natural world and access the parts of science that affect your life.
Explanation:
Answer:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
i hope this helps!
