Answer:
In the film version, they discover that he is still alive by noticing two things on the satellite imagery:
The Rover has been moved from where it was parked originally (prior to the evacuation)
The solar panels had been cleaned.
They also spotted tents attached to the hab for growing potatoes. In the film, the potatoes were grown completely inside the HAB, so no external tents would have been seen by the satellite.

What is the formula mass of NaCl?
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 = ?

Compared to atoms of metals, atoms of nonmetals generally
A)have higher electronegativities
B)have lower first ionization energies
C)conduct electricity more readily
D)lose electrons more readily
Compared to atoms of metals, atoms of nonmetals generally conduct electricity more readily. Therefore, option C is correct.
What are metal atoms ?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)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:

A compound is determined to have the empirical formula C2OH4. If the molar mass of the compound is 132 g/mol, determine the molecular formula of the compound.
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]

Calculate the number of sucrose molecules in a 75.0 gram sample.
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)

Which pair best represents a metallic bond?
A. carbon and oxygen two
B. hydrogen atoms two
C. gold atoms
D. sodium and chlorine
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.
Which ion forms the strongest ionic bond with a given anion?
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.
