Answer 1

Answer:

A compound ‘X’ reacts with dilute HCl and forms a gas ‘Y’. Then the gas ‘Y’ reacts with

compound ‘Z’ and forms compound ‘X’ back. Identify X, Y and Z. Write all the reaction

involved in itFigure 1. Beryllium hydride.

Figure 2. Boron trichloride.

Figure 3. The Lewis structure for nitrogen dioxide, an odd electron molecule.

Figure 4. Phosphorus pentachloride. Left image: Lewis structure Right image: molecular model.

Figure 5. Sulfur hexafluoride.Write rational numbers that are equal to their reciprocals.1 and -1 are the only rational numbers which are their own reciprocal. No other rational number is equal to its own reciprocal. So the rational numbers that are equal to their reciprocals are 1 and -1.The force that the body feels, therefore, is dissipating the kinetic energy of the recoiling gun mass. A heavier gun, that is a gun with more mass, will manifest lower recoil kinetic energy, and, generally, result in a lessened perception of recoil. ... Lowering momentum lowers recoil, all else being the same
