Lower temperature

Let's verify

  • Pressure=P
  • volume=V
  • Temperature=T

As per Boyles law

\\ \rm\Rrightarrow V\propto \dfrac{1}{P}

As per Charles law

\\ \rm\Rrightarrow V\propto T

\\ \rm\Rrightarrow T\propto \dfrac{1}{P}

So

At higher altitudes lower the pressure so lower the temperature

Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g) Which half reaction correctly describes the oxidation that is taking place?
abruzzese [7]
Zn (s) -> Zn+2 (aq) + 2e-

Zn (s) with a neutral charge is oxidized and looses two electrons in the process to form ZnCl2 (aq) where Zn has a charge of 2+.

An atom X has 2 electrons in its outer orbit. What will it do to form a stable ion?
matrenka [14]

Answer:

In a neutral molecule, the sum of the bonding valance electrons must be equal. So the products of the negative element and its charges and the positive element and its charge must be equal.

Explanation:

C1×N1 = C2×N2

If we have a 3 valance electrons , the 'A' charge will be either +3 or -5 for a full octet and valance electron in 'B' atoms will mostly result in acquisition of additional electrons (2) for an octet and relative charge of -2.

Balancing the two,

3 × A = -2 × B

To be equal, A = 2 and B = 3

Therefore, A²B³
