Hello!
The balanced chemical equation for the reaction between sodium and chlorine is the following:
2Na + Cl₂ → 2NaClTo know the mass of Sodium Chloride produced, we are going to use the following conversion factor to go from grams of Chlorine gas to grams of Sodium Chloride:
So,
56,007 g of NaCl are produced
Have a nice day!
Explanation:
Density = mass/volume
1. Work out the density of ethanol and benzene
Ethanol - mass = 3.9 g and volume = 5 mL
Density = mass/volume =3.9/5=0.78g/mL
Benzene - mass=4.4g and volume = 5 mL
Density = mass/volume = 4.4/5=0.88g/mL
So Benzene is more dense
2. Density=mass/volume=25/7-2=5g/mL
The reason why the volume of the object is 7mL - 2mL is because the amount of displaced water is the volume of the object
3. For the Bohr Model, google the image of it.
Protons are positive charged
Neutrons are neutral
Electrons are negative charged
4. Main difference is the location of the electron in the atom.
Bohr Model : electrons orbits the nucleus in fixed paths
Electron cloud model: only the electron's probable location is determined
Q: Which type of severe weather is related to high-pressure systems
A: A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies. A high pressure system is represented as a big, blue H.
If you take this answer into consideration knowing the weathers, you will get your answer
Answer:
The temperature in Celsius is 383, 7°C
Explanation:
We use the formula PV=nRT. We convert the pressure in KPa into atm:
101,325kPa---1 atm
114kPa--------x=(114kPa x 1 atm)/101,325kPa=1, 125 atm
PV=nRT ---> T= PV/nR
T=1, 125 atm x 35, 9 L/ 0,750 mol x 0,082 l atm/K mol
T= 656, 7 K
0°C= 273K---> 656,7 -273K= <em>383,7°C</em>
Answer:
d) 41.20 mi/gal.
Explanation:
Initial odometer reading, D1 = 651.1 mi
Final odometer reading, D2 = 1314.4 mi
Volume of gas used = 16.1 gal
Gas mileage = (D2 - D1)/V
= (1314.4 - 651.1)/16.1
= 41.2 mi/gal.
