Answer:

Equal

Explanation:

According to Newton's third law of motion, the strength of a reaction is equal and opposite to the strength of the action force.

Newton's third law of motion states that "action and reaction forces are equal in magnitude but opposite in direction".
Therefore, if an object exerts a force of magnitude KN on a body.
The body will in return exert the same amount of force back on the object.
The law gives us an idea that force is paired in their action.

Consider the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2. If 8 moles of FeS2 react with 15 moles of O2, what is the limiting reactant?

omeli [17]

Answer:

Explanation:

for find the limiting reactant you must calculate the moles of the reactants from the amount that you have and from the MM:

MM FeS2 = 120n = 26.2g / 120g/mol = 0,218 mol

MM O2 = 32n = 5,44g/32g/mol = 0,17 mol

The limiting reactant is

If 30.0 mL of a 12.0 M hydrochloric acid (HCI) stock solution is diluted to a volume of 500.0 mL,

klemol [59]

Answer:

The concentration of dilute solution is 0.72M

Explanation:

According to the given question

V1=30 ml

S1 = 12 M

V2= 500 ml

then S2 =?

we all know that V1S1=V2S2

or S2= V1S1÷V2

or S2 = 30×12÷500

or S2= 360÷500

or S2 =0.72 M.

The concentration of dilute solution is 0.72 M

Radium decays to form radon. Which equation correctly describes this decay?<br><br> its D

netineya [11]

Answer:

The equation that correctly describes the decay is :

$\frac{226}{88}$ Ra -----> $\frac{222}{86}$ Rn + $\frac{4}{2}$ He

Explanation:

When the solid radium start decaying in order to form the radon gas, it starts losing two protons with one neutron. The two neutron as well as one proton together forms an alpha particle, hence a type of radiation is formed. Also we know that radon itself is radioactive as it also leads to the decay, after that it loses an alpha particle and also form an element called as polonium. Radium being the most stable form of isotope, radium 226, also holds a half life of 1600 years. It will decay into radon 222 through the alpha decay or can also lead 212 by ejecting a carbon 14 nucleus.
