Answer:
1.10 g H2
Explanation:
I took the test and got the answer correct
Water vapor >> water >> ice
Water vapor is the gaseous form of water, only achieved when water is heated to a boil or under certain higher pressure circumstances. Water is a liquid in temperatures between 0-100°C (32-212°F). Ice, the solid form of water, occurs when water freezes, at temps below 0°C (32°F).
Buoyancy is a force that acts on objects that are placed in a fluid is the correct answer
Let me know if I agit it!
Atomic radius
Explanation:
A decrease in moving from the bottom of Group 3 to the top of the group shows an increase in trend from top to bottom.
The atomic radius of elements increases from top to bottom and decreases from the bottom to the top.
The elements in group 3 are B, Al , Ga, In and Tl
- Atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.
- Downs a group from top to bottom, atomic radii increases progressively due to successive shells being added.
- This compensates for the size reducing effect of the increased nuclear charge.
