<u>Answer:</u> The mass of hydrogen gas is 12 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of hydrogen gas = 2 g/mol

Moles of hydrogen gas = 6.0 moles

Putting values in above equation, we get:

6.0mol=\frac{\text{Mass of hydrogen gas}}{2g/mol}\\\\\text{Mass of hydrogen gas}=(6.0mol\times 2g/mol)=12g

Hence, the mass of hydrogen gas is 12 grams

Mass = moles x molar mass
so mass of 6 moles of h2 is: 6×1×2 = 12g

How many atoms are in 35 grams of table salt
Slav-nsk [51]
Adopting the number of avogrado 6.02 * 10²³ / mol 
<span>Sodium chloride (table salt)</span> Molar Mass = 58.44 g / mol 
We will first have to find the number of moles in 35 grams of the element, like this: 
 
1 mol ----------------- 58.44 g 
X ---------------------- 35 g 
 
58.44 * x = 35 * 1 
58.44x = 35 
X = \frac{35}{58.44}
X = 0.598904...
X ≈ 0.60<span> mol </span>
 
Now we will find how many atoms there are in 0.60 mol of this element, like this: 
 
1 mol -------------------- 6.02 * 10²³ atoms 
0.60 mol ----------------- X 
 
X = 0.60 * 6.02 * 10²³ 
\boxed{\boxed{x \approx 3.612 * 10^{23}\:atoms}}\end{array}}\qquad\quad\checkmark

A student made a graph to show the chemical equilibrium position of a reaction.
pogonyaev

Answer:

Concentration, because the amounts of reactants and products remain constant after equilibrium is reached.

Explanation:

The rate of reaction refers to the amount of reactants converted or products formed per unit time.

As the reaction progresses, reactions are converted into products. This continues until equilibrium is attained in a closed system.

When equilibrium is attained, the rate of forward reaction is equal to the rate of reverse reaction, hence the concentration of reactants and products in the system remain fairly constant over time.

When deducing the rate of reaction, concentration of the specie of interest is plotted on the y-axis against time on the x-axis.

Answer:

Explanation:

Food moves through the digestive system with a wave-like motion called peristalsis. Muscles in the walls of the hollow organs contract and relax to cause this movement, which pushes food through the esophagus into the stomach.Apr 25, 2018
