the sodium- nuclide radioactively decays by positron emission. write a balanced nuclear chemical equation that describes this process.

Answers

Answer 1

When the sodium nuclide decays by positron emission, a balanced nuclear chemical equation can be written to describe this process: [tex]22/11Na → 22/10Ne + 0/+1e[/tex] In this equation, 22/11Na represents the sodium nuclide (with a mass number of 22 and an atomic number of 11).

This nuclide decays by emitting a positron, which is represented by 0/+1e. The result of this decay is a new nuclide, 22/10Ne (neon with a mass number of 22 and an atomic number of 10). Positron emission is a type of radioactive decay in which a proton in the nucleus is converted into a neutron, releasing a positron in the process.

This happens when the nucleus has a low neutron-to-proton ratio and needs to increase it for stability. In the case of sodium, its nucleus has too many protons and not enough neutrons, leading to an unstable configuration.

As the proton transforms into a neutron, a positron is emitted from the nucleus. The emitted positron carries away the excess positive charge, thereby reducing the atomic number by one while keeping the mass number constant. The result is a new element with a more stable nucleus. In this case, sodium transforms into neon, which has one fewer proton and one additional neutron in its nucleus.

what is the correct answer ?

Answers

Answer:

Element with 6s subshell

Explanation:

Reactivity of an element depends on the electronic configuration and position of element in the periodic table as reactivity increases as we go down the periodic table.

This is so because number of shell increases as move down the periodic table and the last electron is further away from the nucleus.

Element with 6s subshell is the largest among 3s and 4s subshell and has more number of shells so it will react more than 3s and 4s subshell.

Hence, the correct answer is "Element with 6s subshell".

B. The difference in cloud cover between land and water

C. The difference in specific heat capacity between land and water
D. The difference in elevation between land and water

Answers

Answer:

The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water. What is the cause of a sea breeze? The air over the land is warmed and rises, to a greater temperature than that over the sea.

Explanation:

Your answer is C ! <3

The difference in specific heat capacity between land and water is the cause of sea breeze.

What is sea breeze?

land and ocean heat up at different rates, sea breezes often occur during hot, summer days. The land surface warms up more quickly than the water surface during the day. As a result, the air above land is warmer than that over water.

Just to refresh your memory, warmer air is lighter than cooler air. Warm air rises as a result. As a result, the warmer air above the ground is rising. The cooler air above the water is moving across the surface of the land to replace the rising heated air as it rises over the land.

This is the sea breeze, which is seen at the top of the next picture. The land breeze that happens is seen at the bottom of the following picture.

Therefore, The difference in specific heat capacity between land and water is the cause of sea breeze.

Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.

Granite tor are the rock masses above the ground surface which are  associated with granites

Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.

Hence, the correct answer is "Physical weathering'.

You start with 100mL of 14M HNO3 and 10grams of copper metal. How many moles of the nitrogen dioxide gas will be produced?

Answers

Answer:

0.316 moles are produced.

Explanation:

We state the redox reaction:

4HNO₃   + Cu   →  Cu(NO₃)₂ + 2NO₂ + 2H₂O

We need to determine the limting reactant:

0.1 L . 14 M = 1.4 moles

10 g . 1mol/ 63.54g =0.158 mol

Cu is the limiting reactant. Let's see

4 moles of acid need 1 mol of Cu to react

1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles

We do not have enough Cu.

1 mol of Cu can produce 1 mol of NO₂

Then 0.158 moles will produce, 0.316 moles. (double of moles)

If we see stoichiometry, ratio is 1:2

The solubility of AgNO3 at 10° and 20°C are 170g and 222g per 100g H2O. What is the sign of change of heat of solution for AgNO3?

Answers

Answer:

The sign of change of heat of solution is positive

Explanation:

The dissolution of AgNO3 in water is represented by the equation;

AgNO3(s) --------> Ag^+(aq) + NO3^-(aq)

We can see from the question that as the temperature was increased from 10° to 20°C the solubility of the solute increased from  170g to 222g per 100g of H2O.

This implies that the solubility of the solute increases with increase in temperature.

If a reaction moves in the forward direction when the temperature is increased, then the reaction is endothermic. If the reaction is endothermic, the sign of change of heat of solution is positive.
