How many chlorine atoms are there in 100 g of carbon tetrachloride
Answer:
1.566x10²⁴ atoms of Cl
Explanation:
In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:
Moles CCl₄: 153.82g/mol
100g * (1mol / 153.82g) = 0.65 moles CCl₄
Moles Cl:
0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl
Atoms Cl:
2.6 moles Cl * (6.022x10²³ atoms / mol) =
1.566x10²⁴ atoms of ClThe shape of the directly sunlit portion of the Moon as viewed from

A una sustancia que tenia una etiqueta poco legible se le determina de iones de 3.16x10 a la -10 M.Calcula su pH determina si se trata de jugo de naranja o leche magneisa
Answer:
pH = 9.44, leche de magnesia
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

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?
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.

H-C=C-H
ethyne CxHy
A. Unsaturated alkene
B. Unsaturated alkyne
O C. Saturated alkyne
O D. Saturated alkene
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.

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?
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.
