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.

Which of the following is NOT true about the role tectonic forces play in the rock cycle?
1. When plates pull apart, rocks melt, and magma forms igneous rocks.
2. When plates crash together, rocks are buried and form metamorphic rocks.
3. When plates slide over & under each other, the heat & pressure form igneous rocks.
4. When rocks push upward & form mountains, the erosion of the mountains can produce sediment.

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.Provide a brief description of how the respiratory system works
Answer:
The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.

What caused the deer population to grow early on?
A.) An abnormally cold winter caused offspring to die.
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.
The other options show that the populations actually decreased, due to cold temperatures and droughts.

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.
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.
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
