If the volume occupied by the gas molecules shown below were doubled, what would happen to the pressure they exert? (Assume cons

there's no picture here but I guess the answer would be:

considering the constant temperature, if you double the volume, the pressure would be halved.

like: volume is 2, pressure is 4

if 2×2, then:4÷2

What is the mole ratio between H2O and O2

Bess [88]

The balanced equation is 2H2 + O2 –> 2 H2O. It takes two hydrogen atoms for every oxygen atom to produce this reaction, so the mole ratio between hydrogen and oxygen is 2:1

Answer is 2:1

Ammonium nitrate decomposes to dinitrogen monoxide and water. If given 45.7 grams of ammonium

statuscvo [17]

Answer:

20.54 g of H₂O

Explanation:

Since you already have a balanced equation, the next step is to see the ratio between the ammonium nitrate and water in the equation:

NH4NO3(s)—N2O(g)+2H2O

1 mole of ammonium nitrate produces 2 moles of H2O

So we have the ration:

$\dfrac{1\;mole\;of\;NH_4NO_3}{2\;moles\;of\;H_{2}O}$

Let's leave that for later use.

Next step is to covert the mass given into moles. We do that by getting the molar mass of the given and using that as a conversion factor:

Element number of molar mass

atoms of each element

N = 2 x 14.01 g/mole = 28.02 g/mole

H = 4 x 1.01 g/mole = 4.01 g/mole

O = 3 x 16.00 g/mole = <u>48.00 g/mole </u>

80 .03 g/mole

Now we can convert:

$45.7g\;of\;NH_4NO_3\times\dfrac{1\;of\;NH_4NO_3}{80.03\;g\;of\;NH_4NO_3}=0.57\;moles\;of\;NH_4NO_3$

Now we can use this to determine how many moles of H2O this would produce by using the ration we solved for earlier.

$0.57\;moles\;of\;NH_4NO_3\times\dfrac{2\;moles\;of\;H_{2}O}{1\;mole\;of\;NH_4NO_3} =1.14\;moles\;of\;H_{2}O$

And we convert that by getting the molecular mass of H2O, which is 18.02 g/mole:

$1.14\;moles\;of\;H_{2}O\times\dfrac{18.02\;g\;of\;H_{2}O}{1\;\;mole\;of\;H_{2}O} =20.54\;g\;of\;H_{2}O$

But this is only if the whole 45.7 g of ammonium nitrate is used up.

the relationship between the heated air particles inside a hot air balloon and the cooler air outside the balloon?

Tamiku [17]

The heated air temperature from inside the balloon more likely rises since it can't escape its trapped resulting in different density from the cooler air, the cooler air from the outside is a bit denser than the heated.

Answer:

Let's start with the fact that cereals , are made of grains and are mostly carbohydrates. therefore they contain carbon oxygen and hydrogen. They also contain proteins so have nitrogen. Plants have the minerals that are in the soil where they grow, so the list you have is correct. They also generally have added vitamins ad minerals. The vitamins contain C, H, O N, and a few others such as sulfur, The added minerals might contain:copper, iron, zinc, cobalt, selenium, silicon and molybdenum .
