What happened to the ionization energy of hydrogen"H" when its electron affinity​

Chemistry

Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.

How many moles are in 1.9 x 10^25 molecules of carbon dioxide
Mashcka [7]
1 mole ----------- 6.02x10²³ molecules
? moles --------- 1.9x10²⁵ molecules

moles = 1.9 x 10²⁵ * 1 / 6.02x10²³

= 1.9 x 10²⁵ / 6.02x10²³

= 31.561 moles

hope this helps!

Answer:

You weight would be doubled because gravitational force is doubled

2. Challenges:

a. Everyone’s body would have to adjust to the new weight and learn to walk again

b. Earth would be closer to the sun, so everything would be hotter on Earth

c. Flying airplanes and driving cars might no longer work at all (talk about how difficult this would make traveling)

3. Benefits:

a. Time would go by much slower so technically everyone would live longer

b. Balloons wouldn’t fly off anymore

Which of these atoms has the largest number of neutrons in the nucleus?
viktelen [127]

Holonium and Gadolinium has the highest number of neutrons in the nucleus.

Looking at the atoms listed;

Dysprosium has 66 protons

Holonium has 67 protons

Neodymium has 60 protons

Europium has 63 protons

Gadolinium has 64 protons

Then,

Number of neutrons = Mass number - number of protons

For Dysprosium

157 - 66 = 91 neutrons

For Holonium

162 - 67 = 95 neutrons

For Neodymium

149 - 60 = 89 neutrons

For Europium

148 - 63 = 85 neutrons

For Gadolinium

159 - 64 = 95 neutrons

Hence, Holonium and Gadolinium has the highest number of neutrons in the nucleus.

Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical
ValentinkaMS [17]

Answer:

1) Yes

2) No

Explanation:

A strip of solid magnesium metal is put into a beaker of 0.053M ZnSO4 solution-YES

A chemical reaction occurs

Mg(s) + ZnSO4(aq) ----------> MgSO4(aq) +Zn(s)

This reaction is possible because magnesium is far higher than zinc in the activity series of metals hence magnesium can displace zinc from a solution of a zinc salt.

A strip of solid zinc metal is put into a beaker of 0.058M MgBr2 solution. NO

A chemical reaction does not occur because magnesium is higher than zinc in the activity series hence zinc cannot displace magnesium from a solution of its salt.
