Which type of bone is this covalent bondhydrogen bond ionic bond​

Physics
1 answer:
Fynjy0 [20]4 years ago
5 0

Answer:

Explanation:A covalent bond is formed when electrons are shared between non-metal atoms, and the positive nuclei are attracted towards the pair of negative bonded electrons. ... Hence, the hydrogen bond is weaker than ionic and covalent bonds. Example: Water molecules are held to each other by intermolecular forces of attraction.

Which of the following statements are true concerning the creation of magnetic fields?
Soloha48 [4]

Answer:

A moving electric charge creates a magnetic field at all points in the surrounding region.

An electric current in a conductor creates a magnetic field at all points in the surrounding region.

A permanent magnet creates a magnetic field at all points in the surrounding region.

Explanation:

Magnetic field can be produced by:

- moving charges (i.e. a moving electron, or a current in a conductor)

- A magnet

The strength of the magnetic field produced by a current-carrying wire is

B=\frac{\mu_0 I}{2\pi r}

where

I is the current

r is the distance from the wire

As we see from the formula, the magnetic field is produced at all points in the surrounding region, because B becomes zero only when r becomes infinite. The same is true for the magnetic field created by a single moving charge or by a magnet.

The following choices instead are not correct:

- A single stationary electric charge creates a magnetic field at all points in the surrounding region.

- A distribution of electric charges at rest creates a magnetic field at all points in the surrounding region.

Because they involve the presence of stationary charges, and stationary charges do not produce magnetic fields.

Look at the chemical equation. There is a number in the chemical equation that is not a subscript. What do you think the number
Dominik [7]

Answer:

Number of moles or volume

Explanation:

The number 2 on the right hand side signifies the number of moles of the product being formed.

It is necessary to include this number so as not to flout the law of conservation of mass when writing a chemical equation. The law of conservation of mass states that "matter is neither created nor destroyed during the course of a chemical reaction".

Since we must have equal number of matter on both sides of the expression, the coefficient number like the 2 seen in the expression is used to create a balance.

Here, 2 moles of HCl is formed which consists of 1 hydrogen atom and 1 chlorine atom.
