Answer:

With the appropriate security measures nuclear power, as well as other energy sources, can be used safely.

Explanation:

Nuclear energy, as well as other energy sources, can be dangerous if we do not take the appropriate prevention and protection measures. Nuclear power has one of the lowest levels of fatalities per unit of energy generated, as well as low levels of air pollution-related deaths and allows the reduction of carbon dioxide emissions compared to other energy sources. Since its commercialization, in the 70s, the number of nuclear power accidents is very low compared to the number of accidents of other energy sources, having that coal mining is the most dangerous energy activity in history.

I think that without the correct security considerations, all the energy sources can be dangerous, but if we take security measures as using protection barriers, controlling the reactivity of nuclear power plant, making regularly quality and prevention test control, as well as other measures, we can have the benefits of the nuclear power without worrying too much for danger.

Therefore, with the appropriate security measures nuclear power, as well as other energy activities, can be used safely.

I hope it helps you!

Answer:

$KOH + H_2SO_4 \rightarrow K_2SO_4 + H_2O$

Explanation:

A chemical reaction describes the reaction between reactants to produce products.

A chemical equation is represented as a reactant present on the left-hand side of the equation if two or more reactants are present they are separated by the "plus" sign.

On the right side of the equation product is written and if more than one product is formed then these are separated by "plus" sign as in the reactants.

The reactant and the products are separated by an arrow, the head of arrow is in the direction of the product when the reaction is irreversible.

In the case of reversible reactions or chemical reactions that are present in equilibrium, the reactant and product are separated by a double-headed arrow.

Answer: A) Nonmetal carbon shares valence electrons with each nonmetal chlorine forming four covalent bonds.

Explanation: Covalent bond is formed by sharing of electrons between atoms.

Ionic bond is formed by transfer of electrons between atoms.

Carbon with atomic no 6 and has configuration of $1s^22s^22p^2$ . Carbon has 4 valence electrons. It can only share electrons as it is difficult to gain or lose 4 electrons to complete it's octet.
