One step in the industrial production of nitric acid is the reaction of ammonia with oxygen gas. 4NH3(g)+5O2(g)-->4NO(g)+6H2O
balu736 [363]

Answer:

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

Explanation:

Equation of reaction:  4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)

From the equation of reaction, 5 moles of oxygen gas produces 4 moles of nitrogen monoxide gas

1 mole of a gas at STP occupies a volume of 22.4 L

5 moles of oxygen gas occupies a volume of 5 * 22.4 L = 112 L

4 moles of nitrogen monoxide as occupies a volume of 4 * 22.4 L = 89.6 L

Therefore, 89.6 L of nitrogen monoxide gas are produced from 112.0 L of oxygen

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 8.0 * (89.6/112

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

The volume of 1.0 g of nitrogen in a balloon is increased, it causes
Contact [7]

The volume of 1.0 g of nitrogen in a balloon is increased. It causes: the mass of the gas to decrease the density of the gas to increase and the pressure of the gas to decrease the temperature of the gas decrease.

<h3>What is volume?</h3>

How much space an object or substance takes up.

If you increase the temperature of the gas in the balloon, the pressure will initially increase.  The balloon will expand until the pressure inside drops back down and is equal to the pressure outside.

If you increase the atmospheric pressure, the balloon will compress until the pressure inside equals the new pressure outside.

If you remove gas from the balloon, the pressure will drop, causing the balloon to compress until the pressure is again equal to the pressure outside.

if you place the balloon underwater, it will be under greater pressure, causing the balloon to compress until the inside pressure equals the new outside pressure.

CHEM FINAL PLEASE HELP
marta [7]

Answer:

Potassium (K) and Fluorine (F)

Explanation:

A salt is formed with a metal and non-metal element from the periodic table of elements. if you look at the online ptable.com the upper right hand corner of each element shows the valence electrons for each element, and how many are in each shell for that element. Fluorine (F) has 7 valence electrons in its outer most shell, which means there is room for 1 more electron since the second shell can hold a max of 8. Potassium(K) has 1 electron in its outer most shell- which means is can fill in the 1 space available that fluorine has in its outer most shell. Since Potassium(K) is a metal and Fluorine(F) is a non-metal they can form an ionic compound, salt.
