The constant variable is the math problems, the dependent variable is the calculators, and the independent variables are the students
Lithium is Li
<span>Oxygen gas is O2 </span>
<span>Lithium oxide is Li2O </span>
<span>Unbalanced Equation is Li + O2 --> Li2O </span>
<span>There's one O on right side, 2 Os on left, so make coefficient 2 on right side to balance the oxygens. </span>
<span>Li + O2 --> 2 Li2O </span>
<span>Now balance the lithiums. There are 4 Lis on right side; 1 Li on left, so make Li coefficient 4 to balance the lithiums. </span>
<span>4 Li + O2 --> 2 Li2O </span>
<span>This equation is now fully balanced. </span>
<span>Therefore balanced equation is: </span>
<span>4 Li + O2 --> 2 Li2O</span>
Answer:
1.Nucleus 2.Cytoplasm 3. Vacuoles 4.chloroplasts 5. Body Cell 6. Cell Wall 7. Membrane
Explanation:
- The nucleus is the control center of the cell.
- The jelly-like substance inside the cell is called as cytoplasm.
- They are found in both animal and plant cells but are much larger in plant cells.
- In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
- The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.
- Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
Answer:
The <u>Law of Conservation of Energy</u> is the total energy of an isolated system that is remaining constant, it is conserved over time.
Explanation:
How does it relate to a chemical reaction: Chemical energy is converted to kinetic energy when a stick of dynamite explodes.
Answer:
Unless you mistyped the question, the answer should be 25+
