Answer:
The answer is "[tex]41.23 \ L\ N_2[/tex]"
Explanation:
[tex]2 NO_3^{-} + 10 e^{-} + 12 H^{+} \longrightarrow N_2 + 6 H_2O\\\\= \frac{( 215 \ g \ NO_3^{-})}{(62.0049 \frac{\ g NO_3^{-}}{mol})} \times \frac{(1 \ mol \ N_2}{ 2 \ mol \ NO_3^{-})}\\\\[/tex]
[tex]=3.46746789 \times 0.5\\\\= 1.733 \ mol \ N_2 \\\\\to V = \frac{nRT}{P} \\\\= (1.733 \ mol) \times (0.08205746 \frac{L\ atm}{Kmol}) \times \frac{ (17 + 273) K}{(1.00 atm)}\\\\= 41.23[/tex]
The volume of CO2 is 206.27 L
The ideal gas equation is used to determine the volume, pressure, temperature, or number of moles. It can be mathematically expressed as:
PV = nRT
From the given information:
The equation for the reaction can be expressed as:
[tex]\mathbf{2NO_3^-_{(aq)} + 5CO_{(g)} + 2H^+_{(aq)} \to N_2{(g)} + 5CO_2_{(g)} + H_2O_{(l)}}[/tex]

When 100.0 mL of 1.000 M HCl is reacted with 100.0 mL of 1.000 M NH4OH, the solution’s temperature increases 7.01 °C. Calculate LaTeX: \DeltaΔHreaction in units of kJ/mol. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL.
Do not use units or labels in answer. Make sure answer has the correct sig figs.
Answer:
Explanation:
volume of solution = 100 + 100 = 200 mL
mass of reaction mixture = 200 x 1.010 = 202 g
specific heat of solution mixture = 4.184 J/g-°C
heat evolved = mass x specific heat x rise in temperature
= 202 x 4.184 x 7.01
= 5924.63 J
100 mL of 1 M HCl
= .1 L of 1M HCl will contain .1 mole of HCl
.1 mole reacts with .1 mole of NH₄OH to make 5924.63 J of heat
1 mole reacts with 1 mole of NH₄OH to make 59246.3 J of heat
heat of reaction = 59246.3 J / mol
= 59.246 kJ / mol
= 59.3 kJ / mol .
Can you use mass and volume to predict whether an object will sink or float in water? Explain your thinking.
Answer:
Yes. u can because its easy to tell if an item will sink or float usually by the weight or the width
Explanation:
Can someone please tell me the answer
Answer:
52.068 amu
Explanation:
To calculate the average atomic mass of chromium, you have to first multiply the abundance of an isotope with its mass.
49.946 × 0.0435 = 2.173
51.941 × 0.838 = 43.527
52.941 × 0.0235 = 1.244
53.939 × 0.095 = 5.124
Next, add up all of the values, and you will get the average atomic mass.
2.173 + 45.527 + 1.244 + 5.124 = 52.068 amu
The definition of is the study of quantitative relationships between the amounts of reactants and products.
a)chemical equations
b) stoichiometry
c) molar mass
d)coefficient
Answer:
b) stoichiometry
Explanation:
Stoichiometry is the study of quantitative relationships between the amounts of reactants and products.
The word is coined from two Greek words; stoicheon which means atom and metron which means measurement. It deals with chemical calculations based on the elementary particles of matter. Such calculations highlights the relationships between the composition or chemical reactions of matter and the mole.In order for photosynthesis to take place

A sample of 18.0 g of O2 has a temperature of 350 K, and pressure of 0.720 atm. What is the volume of the sample?
Answer:
V = 22.36 L
Explanation:
Given data:
Mass of oxygen = 18.0 g
Temperature = 350 K
Pressure = 0.720 atm
Volume of gas = ?
Solution:
Number of moles of oxygen :
Number of moles = mass/molar mass
Number of moles = 18.0 g/ 32 g/mol
Number of moles = 0.56 mol
Volume of oxygen:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
0.720 atm × V = 0.56 mol × 0.0821 atm.L/ mol.K × 350 K
V = 16.1 atm.L /0.720 atm
V = 22.36 L

4. Answer, Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.
5. Answer The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.
6.Answer is solid
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
7. Answer Water behaves differently to most other substances because, in its solid state (ice), its particles are less densely packed than in its liquid state. This is why ice floats.
8. Answer 212 degrees F.
Sea Level: Water boils at 212 degrees F. and simmers at 190 degrees F.
9. Answer When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
10. Answer CHEMISTRY TERM PHASE CHANGE
Fusion/Melting Freezing Vaporization/Boilin Condensation Sublimation Deposition Solid to a Liquid Liquid to a Solid Liquid to a Gas Gas to a Liquid Solid to a Gas Gas to a Solid
11. Answer is Energy is consumed (endothermic) to melt ice (solid to liquid) so the opposite process (liquid to solid) must be exothermic.
12.In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.
ok alright. But where’s the question?
