Which statement is true about the ionic size of the elements in a group as one moves from bottom to top in that group?

Ionic size decreases from bottom to top within the group.

Ionic size increases from bottom to top within the group.

Ionic size does not vary in any predictable way within the group.

Ionic size stays the same within the group.

Answers

Answer:

helium

Explanation:

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Answer: 2nd answer " C "

Explanation:

First ionization energy is a periodic trend that increases up and to the right on the periodic table. After looking at the position of these elements on the periodic table, carbon is clearly the best answer-choice (B) aka " C "

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCI?
A. 3.5 mol/L
B. 150 mol/L
C. 3.3 mol/L
D. 3.5 x 10-3 mol/L

Answers

Answer: A) 3.5 mol/L

Explanation:

To determine the molarity, we have to find the number of moles in the volume given, and then extrapolate to find the number of moles that would be in 1 L.

Determine the moles in the given volume

moles of LiCl = mass ÷ molar mass

= 139.9 g ÷ 42.39 g/mol

= 3.30 mol

Find the moles in 1 L

Since 930 mL of LiCl = 3.30 mol

then 1000 mL of LiCl = (3.30 mol × 1000 mL/L) ÷ 930 mL

= 3.55 mol/L

Answers

The answer is true, yw.

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between. This statement is true.

What are conifers ?

Conifers are a type of gymnosperm plants bearing cone like structures in which the seeds are located. Don't be fooled by the fact that coniferous woods are widespread around the world. Some of the wildest trees in the world can be found there.

Hyperion, a coastal redwood tree, is the tallest tree in the world, reaching a height of 379 feet, equivalent to a 35-story structure. From Siberia to Canada, coniferous rainforest biomes can be found. They have cold winters and warm to hot summers.

Temperatures in coniferous forests are quite low all year long. Summertime temperatures range from -7°C to 21°C, while the average wintertime temperature ranges from -54°C to -1°C. Hence, the statement is true.

what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?

Answers

Answer:

9.13 x 10^-8 m

Explanation:

The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

What is wavelength?

Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.

Wavelength is calculated as wave speed and frequency.

Wavelength = speed/frequency

SI unit of wavelength is meter.

A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.

Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
