The number of grams of hydrogen gas in 2600 ml container at 35 degrees celsius and a pressure of 165 mmHg is 0.045g.
How to calculate mass?The mass of a substance can be calculated by multiplying the number of moles of a substance by its molar mass.
However, the number of moles of the substance must first be calculated as follows:
PV = nRT
Where;
P = pressureV = volumen = number of molesR = gas law constantT = temperature0.217 × 2.6 = n × 0.0821 × 308
0.5642 = 25.29n
n = 0.5642 ÷ 25.29
n = 0.0223 moles
molar mass of hydrogen gas = 2g/mol
mass of hydrogen gas = 0.0223 × 2 = 0.045grams
Therefore, 0.045grams is the mass of hydrogen gas.

N2(g) + 3H2(g) → 2NH3(g)
b. How many grams of NH3 result from this reaction?
Work:____________
Ans:_________
Please Help ASAP please
N2(g) + 3H2-> 2NH3(g) This is the balanced equation
Note the mole ratio between N2, H2 and NH3. It is 1 : 3 : 2 This will be important.
moles N2 present = 28.0 g N2 x 1 mole N2/28 g = 1 mole N2 present
moles H2 present = 25.0 g H2 x 1 mole H2/2 g = 12.5 moles H2 present
Based on mole ratio, N2 is limiting in this situation because there is more than enough H2 but not enough N2.
moles NH3 that can be produced = 1 mole N2 x 2 moles NH3/mole N2 = 2 moles NH3 can be produced
grams of NH3 that can be produced = 2 moles NH3 x 17 g/mole = 34 grams of NH3 can be produced

What is the chemical compound that can cause algal blooms and cultural eutrophication in streams?
Phosphorous and nitrogen are the chemical compound that can cause algal blooms and cultural eutrophication in streams.
The cultural eutrophication is the natural aging process of aquatic ecosystems over time. Cultural eutrophication is the human-caused acceleration of aging usually resulting from increased nutrient input. This results in algal blooms, which in marine environments may cause red tides and dead zones. Eutrophication is characterized by excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis such as sunlight, carbon dioxide, and nutrient fertilizers. Eutrophication occurs naturally over centuries as lakes age and are filled in with sediments. human activities have accelerated the rate and extent of eutrophication through nitrogen and phosphorus, into aquatic ecosystem.

A gasoline engine absorbs 2500 j of heat and performs 1000 j of mechanical work in each cycle. The efficiency of the engine is.
The efficiency of the engine that absorbs 2500 J of heat and performs 1000 J of mechanical work in each cycle is 40%.
The formula for the engine's efficiency is as follows:
η = (W/Q) x 100
η = the engine efficiency
W = work done by the engine
Q = heat absorbed by the engine
Q = 2500 J is the amount of heat that a gasoline engine can absorb.
Engine performs mechanical work at a rate of W = 1000 J.
The idea of engine efficiency is frequently used to rate and quantify the propensity to perform work. The ratio of work produced to the amount of heat supplied is used to express it.
So, the efficiency of the engine:

Sodium azide NaN3 decomposes when heated according to the equation 2 NaN3 (s) → 2 Na(s) + 3 N₂ (g) The reaction is used to fill balloons, called air bags, inside motor vehicles to protect passengers during accidents. Calculate the mass of sodium azide needed to fill a 48dm³ air bag with gas, measured at r.t.p.
Answer:
Explanation:
To calculate the mass of sodium azide needed to fill a 48dm³ air bag with gas at r.t.p., you need to use the ideal gas law. The ideal gas law states that the pressure of a gas is directly proportional to its temperature (in Kelvins) and the number of moles of gas present, and inversely proportional to its volume. The ideal gas law can be expressed as:
PV = nRT
Where:
- P is the pressure of the gas
- V is the volume of the gas
- n is the number of moles of the gas
- R is the ideal gas constant
- T is the temperature of the gas
You can rearrange the ideal gas law to solve for the number of moles of gas present:
n = PV / RT
To solve this problem, you need to plug in the known values. At r.t.p., the pressure is 1 atm, the temperature is 273 K, and the volume is 48 dm³. The ideal gas constant is 8.31 J/mol*K. Plugging in these values, you get:
n = (1 atm * 48 dm³) / (8.31 J/mol*K * 273 K)
Solving for n, you get:
n = 0.0174 moles
Now that you have the number of moles of gas present, you can use the balanced chemical equation for the decomposition of sodium azide to calculate the number of moles of sodium azide needed. The balanced chemical equation is:
2 NaN3 (s) → 2 Na(s) + 3 N₂ (g)
This equation tells you that for every 2 moles of sodium azide that decompose, you get 3 moles of nitrogen gas. Since you need 0.0174 moles of nitrogen gas, you can divide that number by 3 to get the number of moles of sodium azide needed:
0.0174 moles N₂ / 3 moles N₂/2 moles NaN3 = 0.0087 moles NaN3
To convert the number of moles to mass, you need to know the molar mass of sodium azide. The molar mass of sodium azide is 65.01 g/mol. Plugging in the number of moles and the molar mass, you get:
0.0087 moles NaN3 * 65.01 g/mol = 0.5686 g NaN3
So, the mass of sodium azide needed to fill a 48dm³ air bag with gas at r.t.p. is approximately 0.5686 grams.

What is the partial pressure of oxygen when this mixture is delivered at a total pressure of 7.8 atm
When this mixture is supplied at a total pressure of 7.8 atm, the partial pressure of oxygen will be 0.0198 atm.
The amount of pressure that each gas in a mixture exerts is referred to as "partial pressure." This is found by using the formula, Partial pressure = Mole fraction × Total pressure.
First, find the mole fraction of the oxygen gas. This is calculated as follows,

What is iron III carbonate's chemical formula?The chemical name for iron III carbonate is [Fe 2 (CO 3) 3].The substance having the chemical formula Fe2(CO3)3 Fe 2 (C O 3) 3 is known as iron (III) carbonate.Fe2(CO3)3 + H2SO4 is a neutralisation reaction, which results in the formation of a salt as the carbonate and acid combine. Iron (4 Fe (s) + 3 O 2) ( g ) Oxygen 2 Fe Ferric oxide is 2 O 3 (s).The formula just lists the first element's name. By taking the element name's stem and adding the suffix -ide, the second element is given a name. A series of numerical prefixes are used to describe how many atoms there are in a given molecule.Learn more about fernic carbonate here:

The table shows the relative atomic masses of some common elements. Use this information to work out the relative formula mass of magnesium sulfate. The formula for magnesium sulfate is MgSO4.
The relative atomic mass of Mg is 24.3, the relative atomic mass of S is 32.1, and the relative atomic mass of O is 16.0.
What is relative atomic mass?The relative atomic mass is a unit of measurement used in chemistry to express the mass of an atom of an element.It is defined as the ratio of the mass of an atom of an element to one twelfth of the mass of an atom of carbon-12.It is often used to compare the masses of atoms of different elements.The relative atomic mass is usually represented by the symbol "A" or "Ar" and is measured in atomic mass units (amu).It is important to note that the relative atomic mass is different from the atomic mass, which is the actual mass of an atom in grams.To calculate the relative formula mass of magnesium sulfate, we add up the relative atomic masses of each element in the formula:Mg = 24.3S = 32.14 x O = 4 x 16 = 64.0So, the relative formula mass of magnesium sulfate is 24.3 + 32.1 + 64.0 = 120.4.To learn more about relative atomic mass refer:

What causes the trend in atomic radius across a period and within a group?
Atomic radius is the distance from the atom’s nucleus to the outer edge of the electron cloud.
Atomic radius decreases across a Period, but increases down a Group.
In a period, from left to right, with increase in the atomic number, the atomic radius decreases due to increase in the nuclear charge which increases the attraction of the nucleus for the valence electrons.
In a group, on moving from top to bottom, the ionic radius increases as a new energy level is added at each succeeding element but the number of valence electrons remains same.
