<span>b) earths outer iron core

</span><span>A coil of wire that is carrying a current and produces a magnetic field is called a solenoid. So the correct option is option "B", in regards to the question given. The term solenoid was first invented by the famous French physicist named Andre-Marie Ampere. In the terms of a physicist, it indicates a coil that has a far greater lenth than the diameter and is wrapped around a core made of metal to create a uniform magnetic field. If a compass is brought near the wire through which current is passing, it will indicate the direction in which the current is flowing. </span>

The Lewis dot notation for two atoms is shown.

Iteru [2.4K]

Answer:

Mg donates two electrons to O

Explanation:

Lewis dot notation uses dots and crosses to represent valence electrons on atoms.

Magnesium is a metal and would donate or lose electrons during bonding.

Oxygen is a non metal and would gain electrons during bonding.

The correct option is;

Mg donates two electrons to O

Which mineral(s) might you be examining if you place some hydrochloric (hcl) acid on a sample and it fizzes?

makvit [3.9K]

The minerals that one might be examining if you place some hydrochloric acid on a sample and it fizzes are Calcite and Dolomite.
Calcite and dolomite are very similar minerals. Both have the same hardness, the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test; A drop of 1 M HCl on calcite produces an instant , obvious Fizz; a drop on dolomite produces slow or no obvious bubbling.

Calculate the % composition of the unknown liquid using your most precise result. It is a mixture of ethanol (D[ETOH] = 0.7890 g

Rufina [12.5K]

% composition of ethanol = 34.51%

% composition of water = 65.49%

<h3>What is density?</h3>

A material's density is defined as its mass per unit volume.

Given data:

The density of ethanol = 0.7890 g/mL

The density of water = 0.9982 g/mL

The density of mixture = 0.926 g/mL
