Which set of properties does a substance such as CO2(g) have?

Answers

Answer 1

Answer: Since CO2 (Carbon Dioxide) is a gas these properties would be: -no definite shape and volume. A gas is invisible and colorless to the human naked eye. An example of pure gas would be like air. Just like air, you see no definite shape and weight or volume.

A radioactive nuclide is used to detect eye tumors. An atom of this radionuclide contains 15 protons, 15 electrons, and 17 neutrons. Which is symbol of this radionuclide?

Answers

15 protons and 15 electrons, but 17 neutrons.

Having 17 neutrons (not even to the # of protons) would result in a radioactive isotope. An isotope is when the neutrons in the nucleus aren't equivalent to the protons.

The symbol of radionuclide would be : An isotope

Hey there

We know that a radioactive nuclide is used to detect eye tumors. An atom of this radionuclide contains 15 protons, 15 electrons, and 17 neutrons.

The answer is isotope. Atoms that have the same number of protons but different numbers of neutrons are called isotopes.

When a liquid is cooled, the kinetic energy if the particles A. Decrease B. Increases C. Remains the same. The force of attraction between the particles A. Decrease B. Increases C. Remains the same , the space between the particles A. Decrease B. Increases C. Remains the same

Answers

Answer:

(A.) Kinetic energy decreases
(B.) Force of attraction increases
(C.) Space between particles remains the same

Explanation:

Kinetic energy is the energy in motion. Cooling if liquid would cause decreased temperature and hence slow down the oscillation of the particles.

Likewise, increased heat reduces the force of attraction between said particles, which allowed for their free movement. So the cooling would have opposite effect.

Finally, the space between the particles would remain the same as it was originally, as their force of attraction is increased in the cooling process, they would take the form they are held in.

What is the approximate pH at the equivalence point of a weak acid-strong base titration if 25 mL of aqueous formic acid requires 29.80 mL of 0.3567 MNaOH? Ka = 1.8×10−4 for formic acid.

Answers

Explanation:

Below is an attachment containing the solution

Answer:

pH= 0.369

Explanation:

The formic acid reacts with NaOH as

HCOOH + NaOH= HCOONa + H2O

Apply CaVa/ CbVb = Na/Nb

Ca×25/(29.8×0.3587) = 1/1

Ca= (29.8×0.3587)/25= 0.428M

pH = - log(H+)

Since only 0ne H+ is in the stoichiometric equation, it means H+ = 0.428M

pH = -log(0.428) =0.369

Mg(s) + 2HCI(aq) -> MgCl2(aq) + H2(g) a. How many grams of HCI are consumed by the reaction of 2.50 moles of magnesium? Given: Requested:

Answers

Answer:2.50 moles of magnesium will consume approximately 182.30 grams of hydrochloric acid in the given reaction.

Explanation:To find out how many grams of hydrochloric acid (HCl) are consumed when 2.50 moles of magnesium (Mg) react with it, you can use stoichiometry and the balanced chemical equation:

Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2(g)

From the balanced equation, you can see that 1 mole of magnesium (Mg) reacts with 2 moles of hydrochloric acid (HCl).

Now, let's use this information to calculate the moles of HCl required to react with 2.50 moles of Mg:

Moles of HCl = (2.50 moles Mg) * (2 moles HCl / 1 mole Mg)

Moles of HCl = 2.50 moles * 2

Moles of HCl = 5.00 moles

Now that we know we need 5.00 moles of HCl, we can calculate the grams of HCl needed using the molar mass of HCl:

The molar mass of HCl is the sum of the atomic masses of hydrogen (H) and chlorine (Cl):

Molar mass of HCl = 1.01 g/mol (for hydrogen) + 35.45 g/mol (for chlorine)

Molar mass of HCl = 36.46 g/mol

Now, calculate the grams of HCl:

Grams of HCl = (5.00 moles) * (36.46 g/mol)

Grams of HCl = 182.30 grams

So, 2.50 moles of magnesium will consume approximately 182.30 grams of hydrochloric acid in the given reaction.
