this is an example of β radiation,
n -> p + e
Rb-87 -> Sr-87 + e
(rem to write atomic numbers in, Rb is 37 and Sr is 38)
The halflife 87Rb is 4,88.1010 years.

Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
The phase change represented by the equation I2s to I2g is called sublimation. This process occurs when a solid directly turns into a gas without passing through the liquid phase.
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O
The equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) using phenolphthalein indicator is: NaOH + HCl → NaCl + H2O Phenolphthalein is a pH indicator that turns pink in basic solutions and colorless in acidic solutions.
3 O2(g) + 2 S(s) --> 2 SO3(g) (This turns into liquid below 45°C)

A quadratic equation can have a maximum of 2 solutions. If the discriminant (b2-4ac) turns out to be less than 0, the equation will have no real roots. If the Discriminant is equal to 0, it will have equal roots. But, if the discriminant turns out to be more than 0,then the equation will have unequal and real roots.
ENERGY + OXYGEN > CARBON DIOXIDE + GLUCOSE. Not sure if this is quite right, but hope it helps:/x

The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
The magnetic field equation for a solenoid is given by B nI, where B is the magnetic field strength, is the permeability of free space, n is the number of turns per unit length, and I is the current flowing through the solenoid. This equation shows that the magnetic field strength inside a solenoid is directly proportional to the current flowing through it and the number of turns per unit length. As a result, increasing the current or the number of turns per unit length will increase the magnetic field strength within the solenoid.
Through the use of the basic transformer voltage equation.
The phase change represented by the equation I2s to I2g is called sublimation. This process occurs when a solid directly turns into a gas without passing through the liquid phase.
Fe2+Cl=FeCl (Original)Fe2+2Cl=2FeCl (Balanced)---- The two in front of the FeCl balances Fe by making it Fe2, but also turns Cl into Cl2. So you put a 2 in front of the Cl reactant, balancing Cl and Fe.
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O
The equation between potassium iodate (KIO3) and sodium thiosulfate (Na2S2O3) involves a redox reaction. In the presence of an acid, potassium iodate is reduced to iodine (I2), while sodium thiosulfate is oxidized to form sodium tetrathionate (Na2S4O6). The balanced chemical equation for this reaction is 5Na2S2O3 + 2KIO3 + 8HCl → 5Na2S4O6 + 2I2 + 2KCl + 6H2O.
