Explanation:

Answer:

2.5 g

Explanation:

The balanced chemical equation for the reaction is:

CH4 + 2O2 → CO2 + 2H2O

From the equation, we can see that for every 1 mole of methane reacted, 2 moles of water are produced. Therefore, we need to first calculate the number of methane and oxygen moles in the reaction mixture.

The molar mass of methane is 16.04 g/mol, so the number of moles of methane present is:

2.41 g / 16.04 g/mol = 0.15 mol

The molar mass of oxygen is 32.00 g/mol, so the number of moles of oxygen present is:

4.6 g / 32.00 g/mol = 0.14 mol

We can see insufficient oxygen to react completely with all of the methane, so oxygen is the limiting reagent. To determine the maximum amount of water that can be produced, we need to use the number of moles of oxygen to calculate the number of moles of water produced and then convert that to a mass using the molar mass of water.

The balanced equation shows that 2 moles of water are produced for every 2 moles of oxygen. Therefore, the number of moles of water produced is:

0.14 mol O2 × (2 mol H2O / 2 mol O2) = 0.14 mol H2O

The molar mass of water is 18.02 g/mol, so the mass of water produced is:

0.14 mol H2O × 18.02 g/mol = 2.53 g

Rounding to 2 significant digits, the maximum mass of water that could be produced is 2.5 g.

The balanced chemical equation for the reaction is

Cl2 + 2HO → 2HCl + O2

If Lysozyme is an enzyme that breaks bacterial cell walls. The molar mass is: 1.40×104 g/mol..

Osmotic pressure (Π):

Π = M × R × T

where:

M is the molarity of the solution

R is the ideal gas constant

T is the absolute temperature.

So,

M = Π / (R × T)

Π = 0.953 torr × (0.001316 atm / 1 torr) = 0.001254 atm

R = 0.0821 atm L mol-1 K-1

T = 25.0°C + 273 = 298 K

Molarity of lysozome solution = (0.001254 atm) / (0.0821 atm L mol-1 K-1 × 298 K) = 0.00005126 mol/L

Molarity of lysozome solution = 0.00005 mol/L

(0.15 g lysozome) × (1 L soln/ 0.00005126 mol lysozome) × (1 / 0.21 L soln) = 13934.56 g/mol

Molar mass of lysozome = 13934.56 g/mol

What is temperature ?

Temperature is a unit used to represent how hot or cold something is. It can be stated using the Celsius or Fahrenheit scales, among others. Temperature shows which way heat energy will naturally flow, i.e., from a hotter (body with a higher temperature) to a colder (body with a lower temperature) (one at a lower temperature).

What is convection currents?

By the mass motion of a fluid, such as water, air, or molten rock, convection currents move heat from one location to another. The ocean currents, atmospheric weather, and geology of the earth are all driven by the heat transfer function of convection currents.

Water boiling in a pot can be seen to have convection currents. The water is heated by the heat source at the pan's base, which also gives the water more energy and causes its molecules to flow more quickly. Water density is impacted by temperature changes as well.

Answer:

molar mass = 79.90 g/mol

Explanation:

Argon as a gas is Ar₂. Molar mass, as found on a standard IUPAC Periodic table, located on most high school chemistry and physics textbooks, as well as data sheets in examinations, is 2×39.95 = 79.90 g/mol.

Answer:

413.9 grams.

Explanation:

First, we need to calculate the molar mass of propylamine (C3H9N):

Molar mass of propylamine = (3 × atomic mass of carbon) + (9 × atomic mass of hydrogen) + atomic mass of nitrogen

Molar mass of propylamine = (3 × 12.01 g/mol) + (9 × 1.01 g/mol) + 14.01 g/mol

Molar mass of propylamine = 59.11 g/mol

Next, we can use Avogadro's number to convert the number of molecules to moles:

1 mole of propylamine = 6.022 × 10^23 molecules

moles of propylamine = (4.21 × 10^24 molecules) / (6.022 × 10^23 molecules/mol)

moles of propylamine = 7.001 mol

Finally, we can use the molar mass to convert moles to grams:

mass of propylamine = moles of propylamine × molar mass of propylamine

mass of propylamine = 7.001 mol × 59.11 g/mol

mass of propylamine = 413.9 g

Therefore, the mass of 4.21×1024 molecules of propylamine is 413.9 grams.

Sickle cell anemia is a genetic blood disorder that affects shape and function of red blood cells.

Sickle cell anemia is a genetic blood disorder that affects the shape and function of red blood cells. Hemostasis refers to process of maintaining balance between clotting and bleeding and sickle cell anemia can disrupt this balance in several ways.

One of the main effects of sickle cell anemia on hemostasis is that it can cause Vaso-occlusion, which is blockage of small blood vessels by sickle cells. This can cause tissue damage, inflammation and pain, which in turn can trigger an overactive clotting response.

Sickle cell anemia is caused by mutations in HBB gene, which provides instructions for making protein called hemoglobin.

Sickle cell anemia is most commonly found in people of African descent, although it can also occur in people of Hispanic, Middle Eastern, and Mediterranean ancestry.

Diagnosis of sickle cell anemia involves blood test to look for the presence of sickle hemoglobin.

Answer:

Explanation:

We can use Boyle's Law, which states that the product of pressure and volume is constant for a fixed amount of gas at a constant temperature. We can use this law to find the final pressure in the cylinder after filling the balloon.

The initial pressure and volume of the helium gas in the cylinder are:

P1 = 38.5 atm

V1 = 32.0 L

The final volume of the gas after filling the balloon is:

V2 = 355 L

Using Boyle's Law, we can write:

P1V1 = P2V2

where P2 is the final pressure in the cylinder.

Solving for P2, we get:

P2 = (P1V1) / V2

Plugging in the values, we get:

P2 = (38.5 atm x 32.0 L) / 355 L

P2 = 3.48 atm

Therefore, the final pressure in the cylinder after filling the balloon is 3.48 atm.

To calculate the energy consumed by the client, we need to use the following formula:

Energy (in calories) = (grams of carbohydrate x 4) + (grams of protein x 4) + (grams of fat x 9)

First, let's calculate the amount of each nutrient in the 180ml serving:

Carbohydrates: (75 ml / serving) x (13.5 g / 75 ml) x 180 ml = 32.4 g

Protein: (75 ml / serving) x (10 g / 75 ml) x 180 ml = 24 g

Fat: (75 ml / serving) x (4 g / 75 ml) x 180 ml = 9.6 g

Now we can calculate the energy consumed:

Energy = (32.4 g x 4) + (24 g x 4) + (9.6 g x 9) = 129.6 + 96 + 86.4 = 312 calories

Therefore, the client has consumed 312 calories from the 180 ml serving of the product.
