The muscular and skeletal system because we use our brain to move our body it sends a signal to move that muscle that we want to use
Answer:
Answer is B.
Explanation:
Hydrogen bonds forms when hydrogen atom is attracted towards oxygen atom of other water. A proton is shared by two ion electrons pair in which oxygen atom is partially negatively charged while hydrogen atom is partially positively charged.
Answer:
3 CO₂ ......a three-carbon molecule
Explanation:
- Photosynthesis involves the synthesis of food by green plants and algae in the presence of energy from the sun, water, and carbon dioxide.
- The process occurs in two stages known as the light-dependent reactions and light-independent reactions also known as the Calvin cycle.
- During light reactions of photosynthesis, water molecules are split by energy from sunlight to give out oxygen gas and hydrogen ions which are channeled to the Calvin cycle.
- Additionally, ATP and NADPH molecules are released.
- In the Calvin cycle, 3 molecules of carbon dioxide are combined with hydrogen ions to yield three carbon-molecules.
- The process also uses ATP and NADPH from the light reactions.
Answer:
506.912 L
Explanation:
From the question given above, the following data were obtained:
Number of mole of O₂ = 22.63 moles
Volume of O₂ =?
Recall:
1 mole of a gas occupy 22.4 L at STP.
With the above information, we obtained the volume occupied by 22.63 moles of O₂ as follow:
1 mole of O₂ occupied 22.4 L at STP.
Therefore, 22.63 moles of O₂ will occupy = 22.63 × 22.4 = 506.912 L at STP.
Thus, 22.63 moles of O₂ is equivalent to 506.912 L.
Nitric acid basically reacts with copper as per to the reaction given 4 HNO3(l) + Cu(s) -----> Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O(l).
<h3>What is a balanced reaction?</h3>
A balanced reaction includes the same number of elements on both sides of the equation.
In a chemical reaction, the stoichiometric coefficient is the number written in front of atoms, ions, and molecules to balance the number of each element between the reactant and product sides of the equation.
The balanced reaction for reaction between copper metal and nitric acid to produce copper II nitrate, nitrogen dioxide, and water will be as follows:
Thus, the above mentioned is the balanced reaction for the given scenario.
