Cyanide is one of those pesky polyatomic ions that just must be memorized. Its formula is CN^{-}. The formula for a sodium ion is Na^{+}. These combine in equal proportions to make NaCN. Its high affinity for metals make this really nasty stuff!

Can you locate any mountains in the tropical zones?
krek1111 [17]

Answer:

At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra. The largest and highest area of mountain lands occurs in the Himalaya -Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south.

In general, the solubility of ________ in water decreases as temperature increases.
Ghella [55]

Solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the liquid and is inversely proportional to the temperature.

So, the solubility of <u>gas </u>in water decreases as the temperature increases.

(II) To make a secure fit, rivets that are larger than the rivet hole are often used and the rivet is cooled (usually in dry ice
KiRa [710]

Given:

Rivet diameter, d_{r} = 1.872 cm

Hole diameter, d_{h} = 1.870 cm

Temperature,  T_{2} = 22 °C

Formula Used:

\alpha = \frac{\Delta d}{d\times \Delta T}

where,

\alpha = coefficient of linear expansion

\Delta d = change in diameter =   d_{h} - d_{r}

\Delta T} = change in temperature =  T_{2} - T_{1}

Solution:

we know that coefficient of linear expansion of steel,  \alpha = 12\times 10^{-6}/^{\circ}C

Using the above formula :

\alpha = \frac{\Delta d}{d\times \Delta T}

12\times 10^{-6}/^{\circ}C = \frac{1.870 - 1.872}{1.872\times \T_{2} - T_{1}}[/tex]

T_{2} - 20/^{\circ}C =   \frac{1.870 - 1.872}{12\times 10^{-6}}}[/tex]

T_{2} = -67.03/^{\circ}C

Therefore, the rivet must be cooled to  -67.03/^{\circ}C
