Answer:

I think number4.Nuclear fusion reaction is not possible in earth

Nuclear fusion and nuclear fission both have common to temperatures over one million degrees Celsius are needed for the reaction to occur. Therefore, option 4 is correct.

A reaction known as nuclear fusion occurs when two or more atomic nuclei fuse to create new atomic and subatomic particles. Energy is released or absorbed depending on how much mass there is between the reactants and products.

Nuclear reactions that involve fusion and fission both yield enormous quantities of energy that can be used to generate power.

The two heavy isotopes of hydrogen, deuterium and tritium, are the primary fuels used in nuclear fusion. Only 0.0153% of natural hydrogen is deuterium, which may be easily and cheaply produced from seawater. Lithium, which is also widely distributed in nature, can be used to create tritium.

Thus, option 4 is correct.

Answer:

.08 L or 80 ml

Explanation:

Use the equation V/t = V/t.

.04L / 150K = V / 300K

.04 / 150 * 300 = V

.08 L or 80 ml

Answer:

189 Joules

Explanation:

Applying,

Q = cm(t₂-t₁)............. equation 1

Where Q = Heat, c = specific heat capacity of water, m = mass of water, t₁ = Initial Temperature, t₂ = Final temperature.

From the question,

Given: m = 15 grams = 0.015 kg, t₁ = 21 °C, t₂ = 24 °C

Constant: c = 4200J/kg.°C

Substitute these values into equation 1

Q = 0.015×4200×(24-21)

Q = 0.015×4200×3

Q = 189 Joules

Explanation:

If it is said that an electric bulb contains 60 watts, that implies that the electric bulb will have to consume a required amount of energy of about 60 joules in a second.

Mathematically:

Power rating = Energy consumed ÷ time

In the number 48.93, the digit that is estimated is the digit "9."

In the number 48.93, the digit "9" is estimated because it falls after the decimal point. When a decimal number, the digits to the right of the decimal point represent fractional or decimal values.

These digits can be estimated or rounded to a certain degree of accuracy, depending on the context or the desired level of precision.

The digit "9" is the last digit after the decimal point, it is likely an estimated value. It means that the actual value could be slightly higher or lower than 9, depending on the level of precision required.

Answer:  A covalently bonded molecule in the reaction

[tex]K + Br_{2} \rightarrow KBr[/tex] is [tex]Br_{2}[/tex].

Explanation:

A bond formed by sharing of electrons between two or atoms is called a covalent bond.

For example, bromine is a group 17 element and it has 7 valence electrons. It needs one more electron to complete its octet.

So, when one bromine atom chemically combines with another bromine atom then sharing of electrons takes place which leads to the formation of [tex]Br_{2}[/tex] molecule.

Hence, in the equation [tex]K + Br_{2} \rightarrow KBr[/tex]; [tex]Br_{2}[/tex] reactant is a covalently bonded molecule. A covlent bond is formed by two or more non-metal atoms that chemically combine together.

In a chemical equation, reactants are written on the left side and products are written on right side.

Thus, we can conclude that a covalently bonded molecule in the reaction

[tex]K + Br_{2} \rightarrow KBr[/tex] is [tex]Br_{2}[/tex].

Answer:

The most acidic solution had a pH of 3.27.

Explanation:

In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.

If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.

Conversely, the least acidic one had a pH of 3.88.

Answer:

pH = 3.5

Explanation:

HCl is a strong acid, so we can use this little formula to find the pH of the solution:

pH = -log[H3O+]

(where H3O+ is the strong acid, HCl)

So we just plug in the molarity for the concentration of the acid...

pH = -log(0.00034)

Solve.

pH = 3.468521083

And apply sig. figs....

pH = 3.5
