Explanation:

Transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay (qq. v.).

Answer:

The temperature will not be affected directly

Explanation:

The solar radiation has a direct effect on the outer surface and inner part of the earth but  an increase by 20% of the solar radiation will not cause the temperature of the Earth's mantle to increase because the factors that heat up the Earth's mantle are : Friction between core materials that sink into the center of the planet and Heat from decay of radioactive materials

Answer:

15

Explanation:

because since the outer shell has 5 electron then add 5 and 10 to get 15

Answer:

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. Mass is denoted using m or M.

Explanation:

the different between mass and weight is that the weight is the measure of the force of gravity on an object and the mass of an object will never change ,but the weight of an iteam can change based on its location

N + H2 → NH3

balance the equation

2N + 3H2 → 2NH3

3H2 → 2NH3

3 : 2

3.91 ÷ 3 = 1.303 mol

1.3 × 2 = 2.606 mol

Answer:

See Explanation

Explanation:

i) The equation of the dissolution of BF2 is;

BaF2(s)⇄Ba2+(aq)+2F-(aq)

ii) Ksp =[Ba2+]  [2F-]^2

iii) Let the concentration/solubility of [Ba2+] and [2F-] be x

Ksp = [x] [2x]^2

Ksp = 4x^3

iv) x =∛Ksp/4

Answer:

3.60X10^-12 is equal to 0.360X10^-11 (move decimal one place left)

Now you can add 3.60X10^-11 and 0.360X10^-11:

3.60X10^-11 + 0.360X10^-11 = 3.96X10^-11

You're really just adding 3.60 to 0.36 since the "X10^-11" is the same for both.

Answer:

An aqueous solution is water that contains one or more dissolved substances. The dissolved substances in an aqueous solution may be solids, gases, or other liquids.

Answer:

A. 21 J

Explanation:

Your temperature change is 10 degrees Celsius, or 10 Kelvin, it makes no difference either way.

Cp = 2.06 J/g•K

Multiply by the temperature change to just get J/g

2.06 J/g•K • 10 K = 20.6 J/g ≈ 21 J/g

21 J is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K) which is heated from 25°C to 15°C. So, the correct option is A.

Heat is defined as the energy that is transferred from one body to another as a result of a difference in temperature, when two bodies at different temperatures are brought together, the energy transferred is that of the hotter body which flows towards the colder body.

In this case, according to the equation for the calculation of the heat during a heating process

[tex]Q= mC (T_f- T_i)[/tex]

It is possible to calculate mass per gram of ice by dividing both sides by removing m from the equation, we plug in the given specific heat and final and initial temperatures to get:

[tex]Q= 2.06 \frac{J}{g degree C} [-15 Degree C- (-25 Degree C][/tex]

[tex]Q= 20.6\frac{J}{g}[/tex] which is equals to 21° C

21 J is the energy change per gram of ice when an iceberg composed of pure water, cp = 2.06 J/(g·K) which is heated from 25°C to 15°C.

Therefore, the correct option is A.

Answer:

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Explanation:

The balanced reaction is:

3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?

[tex]moles of antimony trifluoride=\frac{3*10^{6} moles of freon*2 moles of antimony trifluoride}{3 moles of freon}[/tex]

moles of antimony trifluoride= 2*10⁶

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Answer:

6.022  ×10(index 23) / 7.5 = 0.8293 ×10(index 23)

Explanation:

molar mass of C =  12gmol

therefore in 12g of C there is one mole or an amount of 6.022 ×10(index 23)

∴12g/6.02210(index 23) ×1.6g
