Answer:
a, b and c
Explanation:
To calculate molarity the number of moles and volume in dm3 is needed. So with the mass and molar mass the number of moles can be gotten and hence the molarity when dividing the number of moles by the volume in dm3.
Answer:
What are Boron and Potassium?
Boron <em>is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis,</em> it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust while potassium<em> is a chemical element with the symbol K and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force.</em> Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
What are boron and potassium used for?
Boron<em> is a mineral that is found in food and the environment. People take boron supplements as medicine</em>. Boron is used for building strong bones, treating osteoarthritis, as an aid for building muscles and increasing testosterone levels, and for improving thinking skills and muscle coordination while Potassium <em>is a mineral that plays many important roles in the body. Food sources of potassium include fruits (especially dried fruits), cereals, beans, milk, and vegetables.</em> Potassium is most commonly used for treating and preventing low potassium levels, treating high blood pressure, and preventing stroke.
Answer:It is because acid and water react violently exothermically, producing heat and occasionally melting the fluid.
Explanation:
Answer: <u>Carbohydrates, proteins, lipids, and nucleic acids. </u>
Explanation: The main four basic substances are carbohydrates (elements carbon (C), hydrogen (H), and oxygen (O), lipids, proteins, and nucleic acids. Which all happen to be organic compounds as well.
