I am guessing it is B. Non-metal, metals, metalloids
Metals: located in the South and West of Periodic Table. Tend to give up electrons (form cations) and form simple ionic compounds with non-metal anions. Most of the 118 known elements are metals.
2. Non-Metals : located in the North and East of the Periodic Table. Tend to attract electrons (form anions) and combine with metal cations to make ionics, or share them with other non-metals and form covalent compounds . There are nineteen nonmetals, if we consider the ‘latest” two, which are not well characterized and have fleeting lifetimes.
3. Metalloids: straddle a staircase-like region between metals and non-metals. Their properties are intermediate between metals and non metals (in varying proportions). There are only seven metalloids.
So the answer is B ❤️

If you want to change the mass of your atom by 1 or more mass units, you can either? Add a proton and Add a neutron.
Explanation:
Option A and Option B is your answers.
To change the mass of your atom by more mass units ; you can add a proton or add a neutron ( A and B )
The nucleus of an atom is composed of a neutron and a proton while the outer shell of an atom comprises of the electrons.
The mass of an atom is dependent on the mass of the nucleus of the atom therefore to increase the mass of the atom by any number of mass units you can either add a proton or a neutron to the nucleus of the cell.
Hence we can conclude that to change the mass of your atom you can add a proton or add a neutron to the nucleus of the atom

what is the order in which types of elements are found as you move from left to right across a period? metals, nonmetals, and metalloids?
Answers
Answer:
metals, metalloids, nonmetals
Explanation:
a p e x, just took the quiz
The order is metals, metalloids, non metals in which elements are found as you move from left to right across a period.
MetalsWhen we move from left to right across a period Metals are located on the left hand side of the periodic table. Metals have high thermal conductivity.
MetalloidsWhen we move from left to right across a period Metalloids are located between metals and nonmetals. Metalloids are present p-block elements. Metalloids have good thermal conductivity.
NonmetalsWhen we move from left to right across a period Nonmetals are located on the right hand side of the periodic table. Non metals have low melting point and boiling point. Non metals have low thermal conductivity.
Thus, from conclusion we can say that the order is metals, metalloids, non metals in which elements are found as you move from left to right across a period.

A sports car requires 10 kg of 93 octane to fill the tank. How many grams of octane are in the tank when it is full?
Answers
Answer:
There are 10,000 grams of octane in the tank of the sports car when it is full
Explanation:
To solve this problem, we simply need to convert the mass of octane- 93 from kilograms to grams, using the standard conversion factor which is given below.
it will take 10kg of octane-93 to fill up the tank
1 kg = 1000grammes
therefore 10 kg = 10 X 1000 = 10,000 grams.
Hence, there are 10,000 grams of octane in the tank of the sports car when it is full.

explain why copper 2 oxide is a base although it does not turn litmus paper to blue
Answers
Answer:
See explanation
Explanation:
Copper II oxide is a base but not an alkali. An alkali is a soluble base. Since Copper II oxide is not soluble in water then it is not an alkali.
Let us recall that the change of colour of litmus with an alkali requires the presence of water. In the absence of water, solid Copper II oxide does not turn red litmus paper blue.
The ability to turn red litmus paper blue is commonly observed with alkalis and Copper II oxide is not an alkali.
Also recall that since Copper II oxide is not soluble, hydroxide ions are absent hence Copper II oxide does not turn red litmus paper blue.

Explanation:
Número de iones [H⁺] de 3.6x10⁻¹⁰M
El pH es una medida en química utilizada para determinar si una sustancia es ácida o básica.
Si el pH < 7 La sustancia será ácida (Jugo de Naranja)
Si el pH > 10 La sustancia será básica (Leche de Magnesia)
Ahora, el pH es definido como el -log[H⁺], el pH de la solución será:
pH = -log[3.6x10⁻¹⁰M]
pH = 9.44Como el pH > 7, probablemente se trate de leche de magnesia

Answers
Answer:
Saturated alkyne
Explanation:
The hydrocarbons are known as the compounds which is made up of only carbon and hydrogen atoms. They may be saturated or unsaturated based on the number of bonds present. The molecule H-C≡C-H is an Unsaturated alkyne. The correct option is B.
The hydrocarbons in which the carbon and hydrogen atoms are connected through double or triple bonds are known as unsaturated hydrocarbons. Here ethyne is an unsaturated hydrocarbon.
Ethyne is an alkyne which have the C-C and C-H atoms connected through triple and single bonds.
Thus ethyne is option B.
