1. mol = 77.56/100 = 0.7756 mol
2. mol = 2.55 × 10^24/6.02 × 10^23 = 4.236 mol mass = 4.236 × 74.5 = 315.582 g
3. mass = 0.0931 × 208.3 = 19.393 g
4. mol = 1.55 × 10^22/6.02 × 10^23 = 0.0257 mol
5. molecules = 0.664 × 6.02 × 10^23 = 3.997 × 10^23 molecules
6. mol = 86/242 = 0.355 mol
7. mol = 7.88 × 10^23/6.02 × 10^23 = 1.309 mol mass = 1.309 × 44 = 57.596 g
8. mass = 7.56 × 62 = 468.72 g
9. mol = 7.56/84 = 0.09 mol
10. mol = 8.55 × 10^21/6.02 × 10^23 = 0.014 mol mass = 0.014 × 58.5 = 0.819 g

How many grams of ammonia are produced from 6 moles of nitrogen?
Answers
Answer: The equation is 3H2 + N2 → 2NH3
If 6 moles of H2 gas react with N2 (assuming all reactants react)
6 * 2/3 moles of ammonia must be produced.
Therefore 4 moles of ammonia can be produced.
Since it is a gaseous equation (all reactants/products are gases), we can just assume that the Mr of the gases do not affect the amounts of the reactants or the products.

The enthalpy of combustion of 1 mole of benzene is 3169 kJ/mol .
The first step in answering this question is to obtain the balanced thermochemical equation of the reaction. The thermochemical equation shows the amount of heat lost or gained.
The thermochemical equation for the combustion of benzene is;
2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(g) ΔrH° = -3169 kJ/mol
We can see that 1 mole of benzene releases about 3169 kJ/mol of heat.

Answer:
hola espero que mi respuesta ayude
Explanation:
The concentration of hydroxide ion (-OH) in 1.37 x10^-5 m solution of Ba(OH)2 is calculated as follows
write the equation for dissociation of Ba(OH)2
Ba(OH)2 = Ba^2+(aq) + 2OH^-(aq)
by use of mole ratio between Ba(OH)2 to OH^- which is 1:2 the concentration of OH^- = 2x ( 1.37 x10^-5) = 2.74 x10^-5 M

In giant covalent structures the atoms form strong bonds by sharing electrons.
Answers
Answer:
True
Explanation:
its true don't lie on here please
In giant covalent structures such as graphite or diamond, the atoms form strong bonds by sharing electrons. Therefore, the given statement is true.
What is a covalent bond?A covalent bond can be defined as a chemical connection formed by the sharing of electron sets between particles. A covalent bond can be created by the mutual sharing of electrons from both atoms.
The pair of electrons that are shared in this kind of bonding is known as the shared or bonding pair. Covalent bonds are the sharing of bonding pairs of electrons that will provide the stability of the atom in its outer shell.
Elements that have very high ionization energies are incapable of exchanging electrons or elements having low electron affinity cannot accept electrons. Covalent bonding between two non-metallic atoms is characterized by the equal sharing of electrons between the atoms and covalent bonds with an electronegativity difference of participating atoms is more than 2.0.
Therefore, a giant structure like a diamond has strong covalent bonds that require a lot of energy to break.

The boiling points of five liquids have been measured 10 times each by a team of scientists, with fairly consistent results. Which next step would be the most logical?
1. Test a sixth liquid to see if it follows patterns in the rest of the data.
2. Use a new thermometer to make sure that the original one was not faulty.
3. Continue collecting data until exact boiling points can be found.
4. Test the results an eleventh time, and average the new trial into the data.
Answers
Answer: Test a sixth liquid to see if it follows patterns in the rest of the data.
Explanation:
took the test
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option A. Temperature is a physical quantity.
What is temperature?Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
