Explanation:

Formula when magnesium reacts with hydrochloric acid is given by;

Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)

So, from the equation, we can see that the gas formed is hydrogen.

This hydrogen gas is collected by a method known as water displacement.

This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.

Answer:  Assuming the question: 3.54 ml (3 sig figs)

Explanation:

I don't see a question, but will assume it is "What volume is needed to obtain 26.5 grams?

If so:

(26.5 g)/(7.48 ml) = 3.54 ml (3 sig figs)

Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. Therefore, the volume of solution is 3.54 ml.

Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water.

Mathematically, the formula for density can be given as

Density = Mass of the solution÷ volume marked on the graduated cylinder

7.48 g/mL=Density

Mass of the solution=26.5 g

substituting all the given values in the above equation, we get

7.48 =26.5÷ volume marked on the graduated cylinder

Volume of solution= 26.5/7.48

volume of solution=3.54 ml

Therefore, the volume of solution is 3.54 ml.

A drop of medication is delivered to a patient every 45 s . if 5 drop of this medication occupy 1.0 ml then the medication will be delivered in 15 sec is 4 ml.

According to the question,

1 drop delivered = 45 sec = 0.75 min

and, 5 drop contains = 1.0 ml

then , 1 drop = 1 / 5 ml = 0.2 ml

this mean, 0.2 ml in = 0.75 min

so, how much ml in 1 min,

1 min = 0.2 ml / 0.75

        = 0.266 ml

now, how many ml in 15 min ,

in 15 min = 0.2667 ml × 15

Explanation:

50.68 grams of sodium hydroxide were consumed in the reaction.

Since the balanced chemical equation for this reaction is:

2 Na + 2 H2O -> 2 NaOH + H2

We can see that for every 2 moles of Na used, 2 moles of NaOH are produced, and 1 mole of H2O is produced. Therefore, the moles of NaOH produced in the reaction can be calculated by dividing the moles of H2O produced by 1.

First, let's calculate the moles of H2O produced:

m(H2O) = 45.6 g / 18.015 g/mol = 2.534 mol

Since the stoichiometric ratio of NaOH to H2O is 2:1, we know that the number of moles of NaOH produced is half the number of moles of H2O produced:

n(NaOH) = 1/2 x n(H2O) = 1.267 mol

Now we can use the molar mass of NaOH to calculate the mass of NaOH consumed:

m(NaOH) = n(NaOH) x MM(NaOH) = 1.267 mol x 40.00 g/mol = 50.68 g

(a) To get the pH of the media to 5.8, you would add NaOH solution. NaOH is used as a basic solution, and when it is added to a solution, it will increase the pH of the solution.

(b) The molecular weight of BA is 225.3. To prepare a 1M solution, you would have to weigh out 225.3 grams of BA.(c) To convert a 1M solution of BA to mg/mL, you can use the following equation: 1 mole = molecular weight in grams; 1000 millimoles = 1 mole. So, 1 M = 1000 mg/mL. Therefore, a 1M solution of BA is equivalent to 1000 mg/mL .(d) To convert a concentration of 1000 mg/mL .

Therefore, to calculate the weight required for a 5 mM solution, use the following formula :Mass of BA = molarity × volume × molecular weight= 5 × 0.001 × 225.3= 1.1265 grams(f) To convert a concentration of 5 mM to mg/mL, we use the following formula: Concentration (mg/mL) = (Concentration (mM) × Molecular weight) / 1000= (5 × 225.3) / 1000= 1.1265 mg/mL(g)

To convert a concentration of 1.1265 mg/mL to mg/L, we multiply by 1000, so 1.1265 mg/mL = 1126.5 mg/L.(h) Given that the stock solution of BA is 5 mM and the working solution is 0.2 mg/mL.

Explanation:

The camel consumed approximately 2.24 kg of protein from the Bermudagrass hay.

To calculate the amount of protein the camel consumed, we need to consider the dry matter basis of the hay. Here's how you can calculate it:

Calculate the dry matter weight of the hay:

Dry Matter Weight = Total Weight of Hay × Dry Matter Percentage

Dry Matter Weight = 18.3 kg × (83.4/100)

Dry Matter Weight = 18.3 kg × 0.834

Dry Matter Weight = 15.2442 kg

Calculate the protein content in the dry matter;

Protein Content = Dry Matter Weight × Protein Percentage

Protein Content = 15.2442 kg × (14.7/100)

Protein Content = 15.2442 kg × 0.147

Protein Content = 2.2414194 kg

Therefore, the camel consumed approximately 2.24 kg of protein from the Bermudagrass hay.

To calculate the mass of a chemical that a person ingested, you need to know the concentration of the chemical in the media ingested (water, food). This concentration can be expressed as a ratio or percentage.

Determine the concentration of the chemical in the media ingested. This can be done by measuring the amount of the chemical present in a given volume or weight of the media. Convert the concentration to a standardized unit of measurement, such as milligrams per liter (mg/L) or parts per million (ppm), depending on the chemical and its concentration range.

Multiply the concentration by the volume or weight of the media ingested to calculate the mass of the chemical ingested.  For example, if the concentration of a chemical in water is 10 mg/L and a person ingested 1 liter of water, the mass of the chemical ingested would be 10 mg.

The internal energy change and temperature change for the two processes involving 1 mole of an ideal monatomic gas for (a) ΔU = 3200 J, ΔT = 256.7 K and for (b) ΔU = -3200 J, ΔT = -256.7 K.

The internal energy change and temperature change for the two processes involving 1 mole of an ideal monatomic gas  can be computed using the following formula:

ΔU = Q - W

Where ΔU is the internal energy change, Q is the heat added or taken away from the gas, and W is the work done by or on the gas.

For process (a), 3200 J of heat are added to the gas and the gas does no work and no work is done on the gas. Therefore, the internal energy change is:

ΔU = Q - W = 3200 J - 0 = 3200 J

The temperature change can be computed using the following formula:

ΔT = ΔU / (n * Cv)

Where ΔT is the temperature change, ΔU is the internal energy change, n is the number of moles of gas, and Cv is the molar heat capacity at constant volume.

For an ideal monatomic gas, Cv = 3/2 R, where R is the gas constant. Therefore, the temperature change is:

ΔT = 3200 J / (1 mol * 3/2 * 8.314 J/mol*K) = 256.7 K

For process (b), 3200 J of work are done on the gas and the gas does no work and no heat is added or taken away from the gas. Therefore, the internal energy change is:

ΔU = Q - W = 0 - 3200 J = -3200 J

The temperature change can be computed using the same formula as above:

ΔT = -3200 J / (1 mol * 3/2 * 8.314 J/mol*K) = -256.7 K

Therefore, the internal energy change and temperature change for the two processes are:

(a) ΔU = 3200 J, ΔT = 256.7 K
(b) ΔU = -3200 J, ΔT = -256.7 K
