Calculate the volume of a clear liquid that has a mass of 20 g and a density of 15.77 g/mL.

Answer:

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

Explanation:

Answer:

1800g

Explanation:

b/c d=m/v

m=dv

m=300×6=1800g

The mass of the liquid in the container is equal to 1800 g.

The density of an object can be described as the mass per unit volume of the object. The average density of any substance equals the total mass of the substance divided by its total volume.

The mathematical formula of the density can be expressed as follows:

The density of material = Mass/Volume

Mass = density × Volume

The S.I. unit of the density of any substance is Kg/m³ and it is an intrinsic property. If the size of the substance increases, the mass increases as well but the density of the substance will stay constant.

Give, the density of the liquid, d = 6.0 g/cm³

The volume of the container, V = 300 cm³

The mass of the liquid = 6 ×300 = 1800 g

Therefore, the mass of the liquid is equal to 1800 g.

ELEMENT IS A GROUP OF ATOMS THAT CANNOT BE BROKEN DOWN BY ANY CHEMICAL OR PHYSICAL MEAN

Answer:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.

Explanation:

protons

The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

Answer: A, Carbon Dioxide

Explanation:

A. Soda water, like other carbonated beverages, contains carbon dioxide that has dissolved under pressure. When the pressure is released by opening the soda container, the liquid cannot hold as much carbon dioxide, so the excess bubbles out of the solution.

Answer:

charges, & mass

Explanation:

Since we weren't given the moles of hydrogen, we have to find it. However, we can do it all in one step if we set up the equation correctly.

Since   Mass = moles × molar mass

&         Moles = #molecules ÷ Avogadro's Number

∴ mass = (#molecules ÷ Avogadro's Number) × molar mass

            =  (3.7 × 10⁴⁵ mcules ÷ (6.022 × 10²³ mcules/mole)) × 1.008 g/mol)

            = 6.19 × 10²¹ g

Answer:The answer to your question is It will be formed 0.39 moles of H₂

Data

moles of H₂ = ?

moles of HCl = 0.78

moles of Zinc = excess

Balanced chemical reaction

             2 HCl  +  Zn  ⇒  1 H₂  +  ZnCl₂

Process

Explanation:

1.- Use proportions to solve this problem. Consider the coefficients of the balanced reaction.

              2 moles of HCl ---------------------- 1 mol of H₂

              0.78 moles of HCl -----------------  x

              x = (0.78 x 1) / 2

- Simplification

             x = 0.78 / 2

- Result

             x = 0.39 moles of H₂

Answer:

The answer is 36 atoms

Explanation: I took the test and i got 100%

There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".

We have the expression "6 C₆H₁₂O₆", which represents 6 molecules of C₆H₁₂O₆.

The subscripts are the atomicities of the element, that is, the number of atoms of each element in 1 molecule.

There are 6 atoms of oxygen per molecule of C₆H₁₂O₆. Considering that there are 6 molecules, the total number of atoms of oxygen are:

[tex]6 Molecules \times \frac{6\ O\ atoms}{1Molecule} = 36\ O\ atoms[/tex]

There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".

Most periodic tables have a staircase thick line on their right side. This line separates the metals from the non metals.

O (oxygen) and N (nitrogen) are on the right side of the staircase.

Fe is on the left.

Those elements on the right side of the staircase are non metals.

Those elements on the left of the staircase are metals, so Fe is a metal.

Ionic liquids offer numerous advantages over conventional organic solvents for carrying out organic reactions, Malhotra notes. "In many cases, product recovery is easier, catalysts can be recycled, and the ionic liquids can be reused," he says. "In addition, their thermodynamic and kinetic behavior is different.

Answer:

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.
