Answer:
La fuerza resultante o de reacción por parte de la pared es igual a cero
Explanation:
Aunque se aplique una fuerza de 13 kgf sobre la pared ,esta fuerza no es lo suficiente para que se mueva por lo tanto la pared o el objeto al que se le aplica la fuerza está en equilibrio estático.
El que el objeto o la pared esté en equilibrio estático quiere decir que la resultante de las fuerzas que actúan sobre el objeto es cero.

How many moles are in 12.56 grams of CH4?
Answer:
About 0.783
Explanation:
Answer:
0.7830 mol
Explanation:
Just divide by the molar mass, which is 16.04 g/mol. That will take away grams so youre left with moles and your answer will be .783042. Using significant figures (4) so it will be 0.7830.

how many atoms of argon gas are in 137 ml container at the pressure in the container is 8.80 X 10^5 mmhg and the temperature to 794 K
Answer:
#Ar atoms = 1.47 x 10²²
Explanation:
PV = nRT => n = PV/RT
P = 8.80 X 10⁵ mmHg = 8.80 X 10⁵ mmHg/760mmHg·atm⁻¹ = 11.58atm
V = 137ml = 0.137 Liter
n = ? moles Ar = ? moles Ar x 6.02 x 10²³ Atoms Ar/mole Ar
R = 0.08206 L·atm/mol·K
T = 794K
PV = nRT => n = PV/RT = 11.58atm·0.137L / 0.08206L·atm/mol·K·794K
=> n = 0.0243mole Ar = 0.0244mole Ar x 6.02 x 10²³ atoms Ar/mole Ar
= 1.47 x 10²² atoms Ar

The particles of a liquid are able to move around each other. What property of a liquid does this behavior create?
Answer:
Behaviour is in the form of surface tension.
Explanation:
The particles of the liquid are quite close to each other and move with the random movement around the containers. These particles tend to move rapidly in all directions due to the shorter distances between particles. The property of the liquids to flow is their viscosity. Described as the quality of the liquid to flow. They have no fixed shape, as they are made by tiny vibrating particles that are held together by intermolecular bonds. liquids don't disperse like the gases they have surface tension.newtons forst law of motion is also known as___?

What is the mass in grams of 5.90 moles of aluminum. AI?
Answer:
159.3 grams Al
Explanation:
1 Mol of Al = 27 grams, so:
5.9 Mol Al (27g/1mol) = 159.3 grams Al
The Mol gets canceled out, leaving the unit of grams.

B.) A drought caused there to be less food and water available to the deer.
C.)The number of births was equal to the number of deaths in the deer population.
D.) The deer had a better food source so they had 2-3 fawns per year instead of 1 fawn
per year.
Answer:
i think it is C but not 100% sure.
Explanation:
Answer:
D) The deer had a better food source so they had 2-3 fawns per year instead of 1 fawn per year.

What is a chemical equation, and
how do scientists use these
equations to represent chemical
reactions?
Answer:
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.
In mathematic equations we use an equal sign (=) for example 2 + 2 = 4, but in scientific chemical equations, we use an arrow (→), for example C + O2→ CO2. To the left of the arrow, we have the 'before' situation. This side represents the substances we have beforethe reaction takes place. They are called the reactants.

Which statement describes a way in which a mole is useful
Answer:
A mole in chemistry is defined as the number or quantity of a chemical substance that consists of as many fundamental entities such as atoms, molecules, and ions. Therefore, the statement that best describes a mole is that, it is used for directly comparing the amounts of substances.
Explanation:
I found this hope it helps!! (read and try your best)
Th statement which describes a way in which moles is useful is that it can be used to keep track of chemical amounts.
What is mole?Mole is unit to calculate the amount of chemical substances and it is represented as:
n = W/M, where
W = given mass
M = molar mass
It can be useful in chemical reactions to calculate the relative amount of species present before and after the reaction. In one mole of substance 6.022 × 10²³ atoms of that substance is present.
Hence, option (A) is correct.
