High-temperature superconducting oxides hold great promise in the utility, transportation, and computer industries.
-Dominant- [34]

The main class of high-temperature superconductors are in the class of copper oxides (only some particular copper oxides) especially the Rare-earth barium copper oxides (REBCOs) such as Yttrium barium copper oxide (YBCO).

<h3>What superconducting material works with the highest temperature?</h3>

As of 2020, the material with the highest accepted superconducting temperature is an extremely pressurized carbonaceous sulfur hydride with a critical transition temperature of +15°C at 267 GPa.

<h3>How do high-temperature superconductors work?</h3>

High-temperature superconductivity, the ability of certain materials to conduct electricity with zero electrical resistance at temperatures above the boiling point of liquid nitrogen, was unexpectedly discovered in copper oxide (cuprate) materials in 1987.

Which statement accurately describes covalent bonds
DaniilM [7]
Options are as follow,

<span>A) Covalent bonds are formed by metals and nonmetals.
B) Covalent bonds are are typical of carbon compounds.
C) Covalent bonds are created by the attractions between oppositely charged ions.
D) Covalent bonds break apart when dissolved in water and allow for the conduction of electricity.

</span><span>Answer:
            Covalent bonds are formed by mutual sharing of electrons between two atoms of having electronegativity difference less than 1.7.  Among given options only option-B seems correct.

Explanation:
                    Carbon containing compounds are almost covalent in nature. Majority of organic compounds are made up of carbon, hydrogen, oxygen and nitrogen. And carbon makes covalent bonds with all these atoms.

Result:
          </span>Option-B is correct.

How do I do scientific notation
lina2011 [118]
1. First, move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 0.0000073 you will get 7.3.
2. Next, count how many places you moved the decimal point.

You are to give ampicillin, with a recommended dose of 25 mg/kgmg/kg , to a child with a mass of 24 kgkg . If stock on hand is 2
Anastasy [175]

Answer:

2.4 capsules

Explanation:

You are to give ampicillin, with a recommended dose of 25 mg/kg (25 mg of ampicillin per kg of body weight), to a child with a mass of 24 kg. The mass of ampicillin to be given is:

24 kg body mass × (25 mg ampicillin/ 1 kg body mass) = 600 mg ampicillin

The stock on hand is 250 mg/capsule (250 mg ampicillin per capsule). The number of capsules required to supply 600 mg of ampicillin is:

600 mg ampicillin × (1 capsule/250 mg) = 2.4 capsule
