How would frictional force be affected in space?
Answer:
when two surfaces rub together in outer space, there will be friction. Friction is a surface effect and doesn't depend upon there being air. There is also a force like air resistance from the very sparse gas in space, but it will be very, very small, since space is a very good vacuum.
Explanation:
select the correct word or phrase to complete the statements about ionic compounds. The melting point of an ionic compound is likely to be _____ a molecular compound
Answer:
1. Higher than
2. Soultion and the liquid state
3. hard
4. Have varying solubilities
Explanation:
Ionic bond is a type of intermolecular force formed between a metal and non metal by losing electrons from the metal. The correct phrase which complete the statement is "higher than" a molecular compound.
What is melting point?Melting point is the temperature at which a substance converts to liquid state from solid state where both the phases are in equilibrium. Melting point of a compound depends on the bond type, purity, mass etc.
Ionic compounds are formed between a metal and non metal of higher electronegativity. Metals are electron rich and thus are able to donate electrons to an electronegative atom.
Non- metals such as O,N, halogens forms ionic bond with metals, Ionic bond are strongest of all bond types. Therefore, its very hard to break. As well the ionic network is hard to disorder because they have perfect crystal lattice structure.
To melt a compound the intermolecular attraction have to be reduced in order to liquify the compound. Ionic bond is strong and more thermal energy have to be applied to weaken the bond.
Hence, melting point of ionic compounds is likely to be higher than molecular compounds.

How many mg is 76.0 kg? Express your answer in scientific notation. Use the ^ symbol before the exponent, eg 1x10^3
Milligram and kilograms are two common units of mass. one milligram is 10⁻⁶ kg. Hence, 76 Kg is 76 × 10⁶ mg.
What is mass?Mass of a substance is the measure of its total amount. The standard unit of mass is grams (g). Mass is an extensive property which is dependant on the amount of particles in it.
There are several units of expressing mass, like gram, milligram (mg), kilogram (kg), nanogram (ng), etc. They can be interchanged between each other by certain relations.
Milligram unit is generally used to express the doses of drugs and small quantities.
One milligram = 10⁻⁶ kilograms.
Hence, 1 kg = 10⁶ mg
Therefore, 76 Kg is 76 × 10⁶ mg.

What is the correct formula for carbon ( II ) oxide
Answer:
CO
Explanation:
Carbon(ii) oxide is CO, carbon monoxide. Carbon(iv) oxide is CO2, carbon dioxide. Carbon dioxide, CO2, is caused by the complete burning of any substance containing carbon
The correct formula for the compound carbon (II) oxide is CO.
The formula of a compound is a representation of the types and numbers of atoms present in a chemical substance. It shows the chemical symbols of the elements involved and indicates the ratio of atoms in the compound.
The subscripts in the formula represent the number of atoms of each element in a molecule or unit of the compound. For example, the formula of water is H₂O, indicating that it consists of two hydrogen atoms (H) and one oxygen atom (O) bonded together.

Why is the supply of oil in Texas decreased from its supply fifty years ago? A. Oil is a nonrenewable resource B. Oil is a renewable resource C. Oil takes sixty years to replenish itself. D. Oil wells are no longer being dug.
Answer:
A
Explanation:
The supply of oil in Texas decreased from its supply fifty years ago because oil is a nonrenewable resource.
A nonrenewable resource is one that cannot be replenished naturally at the same pace as its usage and hence, decreases and eventually gets exhausted with usage or exploitation over time. This is unlike renewable energy resource that gets replenished even with usage.
The more the oil in Texas is exploited, the more its supply or reserve will decrease. This is why the supply of oil has decreased from what it is fifty years ago.
The correct option is A.

One way that steel makers can keep steel from rusting is to coat it with zinc metal. If the
workers combine excess steel (FeNiO,) and 75.00g of zinc, how much coated steel (ZnFeNiO)
should they be able to make?

Answer:
225.4 g
Explanation:
The equation of the reaction is;
Zn(s) + FeNiO(s) ------> ZnFeNiO(s)
Since FeNiO is in excess then Zn must be the limiting reactant.
Molar mass of Zn = 65.38gmol-1
Number of moles of Zn reacted = 75g/65.38gmol-1 =1.15 moles
If 1 mole of Zn yields 1 mole of ZnFeNiO
1.15 moles of Zn yields 1.15 moles of ZnFeNiO
Mass of ZnFeNiO produced= 196gmol-1 * 1.15moles = 225.4 g
In the reaction below, how would adding more of reactant A affect the equilibrium of the system? (2 points)
A + B ⇄ C + D
a
Shift it to the right toward the products.
b
Shift it to the left toward the reactants.
c
Equally create more products and reactants.
d
It would have no effect.
Answer:
a . Shift it to the right toward the products.
Explanation:
In the reaction, if more of the reactant A is added to the system, the reaction will shift towards the products.
If a system at equilibrium is disturbed by changing the concentration of one of the substances, all the concentration will change until a new equilibrium point is reached. If we add more reactants, the concentration is increased and the reaction shifts to the right so as to maintain the constancy of the equilibrium constant.Answer: a . Shift it to the right toward the products.

Answer:
Electron cloud
Explanation:
In an atom, the nucleus contains neutrons and protons. Electrons surround the nucleus.Protons are positively charged while electrons are negatively charged.The space in which electrons are located is called an electron cloud. Because this region is composed only of electrons and empty space, it has an overall negative charge.

List the protons, neutrons, and electrons for Ge2+
Please hurry
Answer:
32, 30 and 41
Explanation:
The problem here is to find the number of:
Protons, neutrons and electrons in Ge²⁺
In this ion,
We must understand that for a net positive charge to remain on an atom, the number of protons must be greater than the number of electrons.
Ge is Germanium with atomic number of 32;
So the number of protons is 32
Since the atom has lost two electrons;
Number of electrons now is 32 - 2 = 30
Number of neutrons is 41 from the periodic table.

The new pressure of the gas : 0.75 atm
Further explanationBoyle's Law
At a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
P₁=1 atm ⇒ standart temperature and pressure (STP)
V₁=3 L
V₂=4 L
