Answer from: photon22

The balanced chemical equation for the reaction that occurs when titanium metal undergoes combination reaction with oxygen is;

$Ti(s+ O_{2}(g) = TiO_{2}(s)$

Further Explanation: Chemical equations Chemical equations are equations showing reactions between reactants to form products. Chemical equations show the reactants or starting substances and products or substances formed during the reaction. Law of conservation of mass The law of conservation requires that when writing chemical equations, the mass of the reactants should be equal; to the mass of the products. This is done by making sure the number of atoms of each element involved in the chemical equation is equal on both sides of the equation. To ensure the law of conservation in chemical equations is observed we balance chemical equations. Balancing chemical equation: Balancing chemical equations is a try and error method that ensures the number of atoms in the side of the reactants is equal to the number of atoms in the side of products. Balancing chemical equations may also require inclusion of state symbols which shows the state of each compound or element involved in the chemical reactions. For example; the equation;

$Ti(s+ O_{2}(g) = TiO_{2}(s)$ is balanced as the number of titanium and oxygen atoms are equal on both sides of the equation.

Answer from: cchavcchav9606

$Ti_{(s)}+O_{2}_{(g)}=TiO_{2}_{(s)}$

Explanation:

Titanium reacts slowly with oxygen at high temperatures in the presence of air to form Titanium dioxide.

The reaction is slow due to the resistance of the metal itself to corrosion which forms a layer to decrease the action of oxygen.

The balanced chemical reaction is the following:

$Ti_{(s)}+O_{2}_{(g)}=TiO_{2}_{(s)}$

High-energy and unstable.

Answer from: Quest

Answer : option a) 84explanation :

considering the question as per the attachment

$^{222}_{86}> ^{218}_{84}po+^{4}_{2}he$

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
