Answer:

<h3>OF2 Molecular Geometry</h3><h3 /><h3>As only atoms are bonded with the central atom, it has a molecular geometry similar to AX2 that corresponds to linear geometry. Although the electron geometry of OF2 is tetrahedral, its molecular geometry is linear.</h3>

Calcium metal reacts with water to form calcium hydroxide and hydrogen gas. How much hydrogen is formed when 0.50 g of calcium a
olga55 [171]

Answer:

0.025g

Explanation:

Firstly, we need to write a balanced chemical equation.

Ca + 2H2O —-> Ca(OH)2 + H2

From the chemical equation, we can see that one mole of calcium metal yielded one mole of hydrogen gas.

Now, we need to know the actual number of moles of hydrogen gas given off.

The number of moles is the mass divided by the atomic mass. The atomic mass of calcium is 40g/mol. The number of moles is thus 0.5/40 = 0.0125 mole

Since the mole ratio is 1:1, the number of moles of hydrogen gas produced too is 0.0125 moles.

We now Proceed to get the mass of the hydrogen gas produced. This is the number of moles of hydrogen multiplied by the molar mass of the diatomic hydrogen gas. The molar mass of the diatomic hydrogen gas is 2g/mol.

The amount given off is thus 2 * 0.0125 = 0.025g

Below are shown, for five metals, reduction reactions and standard electrode potential values. which of these metals is the leas
just olya [345]
Above question is incomplete. Complete question is attached below
........................................................................................................................
Solution:
Reduction potential of metal ions are provided below. Higher the value to reduction potential, greater is the tendency of metal to remain in reduced state.

In present case, reduction potential of Au is maximum, hence it is least prone to undergo oxidation. Hence, it is least reactive.

On other hand, reduction potential of Na is minimum, hence it is most prone to undergo oxidation. Hence, it is most reactive.

NISA [10]
<span>Answer for the given question is CaBr2. Although, the given equation requires balancing of by adding one more HBr and one more H2o in resultant. The given equation will product at least one CaBr2. Hence the answer for the given equation is Calcium bromide i.e. CaBr2.</span>
