Answer:True

Explanation:

Answer:

The molar mass of sodium is 22.990 g/mol.

The molar mass of chlorine is 35.45 g/mol.

To calculate the molar mass of NaCl, we need to multiply the subscript of each element times its molar mass, then add them together. In this case since there is no subscript, it is understood to be

( 1 × 22.990 g/mol ) + ( 1×35.45 g/mol ) = ?

22.990 g/mol + 35.45 g/mol = ?

58.44 g/mol = ?

Answer:

Option #2 (Green seeds)

Explanation:

Since both the plants are true-breeding, both plants only have the green allele. Therefore, their offspring must also only have the green allele and will therefore have green seeds.

Answer:

1)They have different densities.

2) The molecules are packed differently

Explanation:

Oil and Water have different densities The first reason that water and oil don’t mix is because their molecules are packed differently. The molecules of water are packed very densely. (Would be good to show water molecules packed densely) In one glass of water, there are more molecules than the number of known stars in the universe!

Answer:

diff densities

Answer: here is your answer

Explanation:

The oxygen family consists of the elements that make up group 16 on the periodic table: oxygen, sulfur, selenium, tellurium, and polonium. These elements all have six electrons in their outermost energy level, accounting for some common chemical properties among them.

Answer:

they all have 6 valence electrons

Explanation:

all elements in group 16 have 6 valence electrons

Answer: The molecular formula will be [tex]C_6O_3H_{12}[/tex]

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

Empirical weight of [tex]C_2OH_{4}[/tex] is [tex]12\times 2+16\times 1+1\times 4=44g[/tex]

Molecular mass of compound is = 132 g

Now we have to calculate the molecular formula.

[tex]n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{132}{44}=3[/tex]

The molecular formula will be=[tex]3\times C_2OH_4=C_6O_3H_{12}[/tex]

Answer:

C. gold atoms

Explanation:

Metallic bonds are found between atoms of metals. Since gold is the only metal given here, it is the solution to the problem.

Metallic bonds join atoms of metals and alloys together.

The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.

The metallic bond is actually an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.

Answer:

Explanation:

A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge. A larger ion makes a weaker ionic bond because of the greater distance between its electrons and the nucleus of the oppositely charged ion.

Compared to atoms of metals, atoms of nonmetals generally conduct electricity more readily. Therefore, option C is correct.

The term metal atom is defined as an atom of an element that exhibits typical metallic properties, being typically shiny, with high electrical and thermal conductivity.

Metallic bonds form when the charge is spread over a greater distance than the size of individual atoms in solids. Most left elements in the periodic table form metallic bonds, such as zinc and copper.

Metals are defined as elements to the left of the line. Elements just to the right of the line have both metal and nonmetal properties and are referred to as metalloids. Nonmetals are elements at the far right of the periodic table.

Thus, option C is correct.

Answer:

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)
