Which of the following statements are true about whether atoms tend to gain
or lose electrons?

Answer:

Mass = 64 g

Explanation:

Given data:

Mass of water produced = 36 g

Mass of oxygen needed = ?

Solution:

Chemical equation:

CH₄ + 2O₂       CO₂ + 2H₂O

Number of moles of water produced:

Number of moles = mass/molar mass

Number of moles = 36 g/ 18 g/mol

Number of moles = 2 mol

Now we will compare the moles of water and oxygen.

             H₂O       :          O₂

                2         :           2

Mass of oxygen:

Mass = number of moles × molar mass

Mass =  2 mol × 32 g/mol

Mass = 64 g

Answer:

25 g

Explanation:

N/No = (1/2)^t/t1/2

N= amount of radioactive material at time t

No = amount of radioactive material initially present

t= time taken

t1/2 = half life of the radioactive material

Substituting values;

N/800 = (1/2)^80/16

N/800= (1/2)^5

N/800= 1/32

32N = 800

N= 800/32

N= 25 g

Answer:

Divide; mass.

Explanation:

The acceleration of an object is equal to the net force exerted on the object divided the object's mass. This theory is known as Newton's second law of motion.

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]

Where;

F represents force.

m represents the mass of an object.

a represents acceleration.

Making acceleration (a) the subject, we have;

[tex]Acceleration (a) = \frac{F}{m}[/tex]

Therefore, the acceleration of an object is equal to the net force exerted on the object divided the object's mass.

The acceleration of an object is equal to the net force exerted on the object divided by the object's mass.

The net force applied to an item divided by its mass gives the object's acceleration.

To put it another way, the equation that connects mass (m), net force ([tex]F_{net[/tex]), and acceleration (a) is:

a = [tex]F_{net[/tex] / m

This equation is derived from Newton's second rule of motion, which states that an object's acceleration is inversely proportional to its mass and directly proportional to the net force acting on it.

Thus, it shows that an item accelerates more quickly the more net force that is applied to it, and that an object accelerates more quickly the more mass that is added to it.

I think it's alkyne!

Please give brainliest!

The compounds containing triple bonds between carbon atoms are called alkynes. The given compounds contains one triple bond between two carbons atoms hence, it is an alkyne.

Hydrocarbons are organic compounds containing carbon- hydrogen bonds. There are three types of hydrocarbons namely alkanes, alkene and alkynes.

Alkanes are compounds containing only single bonds between all carbon atoms in the chain. Alkanes are called saturated hydrocarbons. Alkenes are unsaturated because they contains one or more double bonds between carbon atoms.

Alkynes are compounds with one or more triple bonds between carbon atoms in the chain. Alkynes are also unsaturated. The given compound contains one triple bond between a pair of carbon atoms. Thus, it is an alkyne.

Using gas stoichiometry find the volume of sulfur burned in excess of oxygen: Gas pressure inside a vessel: 1.60 grams of methane (CH4) is combusted.

Answer:

Why?  Because of electron shells.  Technically, they're not fully inert.  They have very low reactivity potential, and can only be forced to become reactive with difficulty.

Explanation:

All chemical reactivity is made possible through the atom's electron arrangement.  Electrons basically have shelves where they live, called "levels" or "shells".  Each level is farther from the nucleus than the previous one.  Atoms are most stable when their outer most shell (called the valence shell) is full.  Atoms with an incomplete shell will react with other atoms, in an attempt to either fill out the outer shell, or to rid itself of it's valence electrons so that that previous level becomes a full valence level.  If the valence shell ils already full, the atom will not be inclined to create compounds.

The first shell can hold up to two electrons.  After the first two electrons, any additional electrons have to begin a new shell.  The second shell can hold eight electrons before it becomes full.  Helium is the first noble gas on the periodic table, having two protons and two electrons.  Because helium's outer most shell is full, it does not react with other atoms.

By comparison, look at hydrogen and oxygen.  Oxygen has eight electrons.  The first two electrons occupy the first shell.  The remaining six go to the second shell.  This leaves the second shell with two empty spaces that can potentially be filled.  Meanwhile, hydrogen has one electron, with it's valence shell having an empty space for one additional electron.  Two hydrogen atoms give up their single electrons to an oxygen atom, so that all three end up with stable valence levels.

By the time an atom can fill out the second electron shell on it's own (10 total electrons) you end up with neon, the second noble gas.

4d - orbital makes the given electronic configuration wrong.

Explanation:

The order of electronic configuration is written as;

1s²

2s²      2p⁶

3s²      3p⁶      3d¹⁰

4s²      4p⁶      4d¹⁰        4f¹⁴

6s²      6p⁶      6d¹⁰        6f¹⁴

7s²      7p⁶       7d¹⁰        7f¹⁴

In order of energy level from the lowest to the highest, the configuration of the given atom in ground state can be written as;

1s²    2s²   2p⁶   3s²   3p⁶   4s²  3d¹, when compared to the given configuration, 4d orbital makes the given configuration wrong, because the next orbital after 4s is 3d.

Answer:

D (Decomposition)

Explanation:

This reaction is a decomposition reaction because one substance (NaNO3) is being separated into two substances (NaNO2 and O2). Alternatively, you could use the process of elimination. The reaction can't be single/double replacement because there's only one reactant, it can't be synthesis because substances are being broken down, not formed, and it can't be combustion because O2 is a product, not a reactant, and CO2 and H2O aren't being produced, as is common with combustion reactions.

Answer:

Ca reducing agent

Fe2+ Oxidizing agent

Explanation:

Ca ------> Ca2+ +2electrons.

Calcium loses two electrons and oxidises itself and reduces others so Ca is a reducing agent.

Fe2+ +2electrons ------> Fe

Fe 2+ reduces itself by gaining electron and oxidizes other so Fe2+ is Oxidizing agent.
