Answer: C) 8 moles
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
According to stoichiometry of the given balanced equation:
2 moles of decomposes to form 2 moles of
Thus 8 moles of decomposes to form= of
Thus 8 moles of are produced from 8 moles of
Answer:
alkali metal
Explanation:
The alkali metals in period 4 will have the lowest ionization energy of the elements in the period.
Across a period ionization energy increases progressively from left to right due to decreasing atomic radii caused by the increasing nuclear charge which is not compensated for by successive electronic shells.
- Ionization energy is the energy needed to remove the most loosely bound electrons of an atom in the gas phase in the ground state.
- The measure of the readiness of an atom to lose an electron is the ionization energy.
Down a group, it decreases.
Answer: Yes
Explanation:
This simulates the way offspring are formed by sperm from the male fish combining randomly with eggs from the female fish.
Answer:
D. 3.844 x 10^5
3.844 is between 1 and 10, so that is correct.
Not C because if it is negative it would be a decimal from 0 e.g -> 0.88
