2 carbon, 4 nitrogen, 8 oxygen
Answer:
The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
Explanation:
<em>Balance Chemical Equation:</em>
2H3N(aq) + 3Ca(OH)2(aq) → Ca3N2(aq) + 6H2O(liq)
<em>Explanations:</em>
- According to law of mass of conservation, the chemical equation should be balanced.
- In balance chemical equations, the numbers of same or different atoms in reactants should be equal to the number of different atoms of elements of product side.
Answer:
1.) 2 molecules
2.) 4 H atoms, 2 S atoms, 2 O atoms
3.) 8 total atoms
Explanation:
1.) 2 H₂SO
--------> The molecule is all of the elements bonded together (H₂SO). Because there is a coefficient of 2 in front of the molecule, this means that there are 2 molecules present.
2.) 2 H₂S₁O₁
---------> The number of atoms of each element is determined by the subscripts and the coefficients. In one molecule, there is one oxygen, one sulfur, and 2 hydrogen atoms (denoted by subscripts). Because there are two molecules, these values are doubled.
3.)
--------> The total number of atoms is calculated by adding the number of atoms of each element. If between 2 molecules there are 4 hydrogens, 2 sulfurs, and 2 oxygens, combined there would be a total of 8 atoms.
I think the correct answer is B. An example of gene therapy is when a defective gene is replaced with a normal gene.
