Answer: 1) A. It is the site of photosynthesis, where glucose is produce.
2) C. The large vascuole is like a water-filled balloon. When the plant is water-stressed, the water leaves the vacuole and the cells shrink.
A neutron has a neutral charge.
A proton is positive while an electron is negative. Neutrons have no charge.
Answer:
CH3+
Explanation:
Sp2 hybridization involves the mixing of on s and two p orbitals. This is observed in CH3+. The ion is trigonal planar with a H-C-H bond angle of 120°.
The anion, CH3^- is sp3 hybridized, hence only CH3+ is sp2 hybridized among the options.
Given the data from the question, the mass of arsenic that contains 1.23×10²⁰ atoms is 0.0153 g
<h3>Avogadro's hypothesis </h3>
6.02×10²³ atoms = 1 mole of arsenic
But
1 mole of arsenic = 75 g
Thus, we can say that:
6.02×10²³ atoms = 75 g of arsenic
<h3>How to determine the mass that contains 1.23×10²⁰ atoms</h3>
6.02×10²³ atoms = 75 g of arsenic
Therefore,
1.23×10²⁰ atoms = (1.23×10²⁰ × 75) / 6.02×10²³ atoms)
1.23×10²⁰ atoms = 0.0153 g of arsenic
Thus, 1.23×10²⁰ atoms is present in 0.0153 g of arsenic
