If a object has a mass of 10 kilograms, how much does it weigh in newtons?

Depends on where the object is. On earth, moon , or somewhere without any other mass (theoretically). I think you mean how much does weigh on earth. So, the average gravitational acceleration on earth is : 9.83 m/s^2 To find out how much an object weighs, this is the formula : G=m.g where m is mass of the object g is the gravitational acceleration and G is weight. So, G = 10.9,83 = 98,3 N is the answer.

Answer:

Molecules

Explanation:

If you had more than one atom chemically bonded together, then regardless of the types of atoms that are bonded, you're going to have a molecule regardless.

Energy of motion or change in position
Sholpan [36]
<span>Kinetic energy is the energy at move or at motion. The kinetic energy of objects depend on its mass (m) and its </span>velocity (v)<span>. The mass of an object can be measured in kilograms while its mass can be measured in meters per second. The objects' energy at motion is very dependent to its mass and velocity therefore, the formula in finding the kinetic energy of an object is </span>

K = 1/2 x mass (m) x velocity (m/s)2

<span>On the other hand, the kinetic energy of atoms and molecules are measured differently. It is measured through temperature.<span>

3. How many atoms are found in 5.20 g of magnesium (Mg)?
Ganezh [65]

Explanation:

In order to go from mass of magnesium to atoms of magnesium, we have to do two things:

   Convert mass of Mg to moles of Mg using the molar mass of Mg as a conversion factor

   Convert moles of Mg to atoms of Mg using Avogadro's number (6.02×1023) as a conversion factor

Step 1:

Before we start, I should note that the molar mass of Mg is 24.31gmol. We can go from mass to moles using dimensional analysis. The key to dimensional analysis is understanding that the units that you don't need any more cancel out, leaving the units that are desired:

48.60g

×1mol24.31g

=2.00mol

Step 2:

We'll use this relationship:

Using the moles of Mg that we just obtained, we can use Avogrado's number to perform dimensional analysis in order to cancel out units of mol to end up with atoms of Mg:

2.00mol

×6.02×1023atoms1mol

=1.204×1024atoms

Thus, 48.60g of Mg is equivalent to 1.204×1024atoms

Hope this helped :)

1. Propane gas (C3H8) burns completely in the presence of oxygen gas (O2) to yield carbon dioxide gas (CO2) and water vapor (H2O
vovikov84 [41]
1) Balanced equation

C3H8 + 5O2 -> 3 CO2 + 4 H2O

2) 0.700 L C3H8

Given the pressure and temperature do not change, the molar ratio is equivalent to volume ratio

1molC3H8 / 5 mol O2 => 1 L C3H8 / 5 L O2

0.700 L C3H8 / x L O2 = 1 L C3H8 / 5 L O2 => x = 0.700 L C3H8 * 5 L O2 / 1 L C3H8

x = 3.500 L O2

3) CO2 produced

1 L C3H8 / 3 L CO2 = 0.700 L C3H8 / x L CO2 =>

x = 0.700 L C3H8 * 3 L CO2 / 1 L C3H8 = 2.100 L CO2

4) Water vapor produced

1) 1 L C3H8 / 4 L H2O = 0.700 LC3H8 / x L H2O =>

x = 0.700 L C3H8 * 4 L H20 / 1 L C3H8 = 2.800 L H2O
