What is the correct formula for magnesium sulfate

Answers

Answer 1
Answer: MAGNESIUM SULFATE is a small colorless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of pre-eclampsia and eclampsia. It causes direct inhibition of action potentials in myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions. (From AMA Drug Evaluations Annual, 1992, p1083).MgSO4
Answer 2
Answer: i guess the answer is MgO4S

Iron has a density of 7.86 g/cm3 (1 cm3=1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.01 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm3 = 1 mL) before calculating the volume for the piece of iron.

Answers

510.17 cm³ is the volume of Iron has a density of 7.86 g/cm3 (1 cm3=1 mL) and has a mass of 4.01 kg.

What is density?

Density is the amount of mass of a substance present per volume of the cubic centimeter and it is the ratio of the mass of a substance to the volume of the substance with a unit centimeter cube.

The Iron has a density of 7.86 g/cm³ and mass of 4.01 kg so,

mass in gram = 4.10 / 1000 = 0.041

Density = mass/volume

Substituting the value in the equation,

volume =  0.041 /7.86 g/cm³

volume = 510.17 cm³

Therefore, the volume of Iron has a density of 7.86 g/cm3 (1 cm3=1 mL) and has a mass of 4.01 kg is 510.17 cm³.

4.01 kg in grams :

4.01 x 1000 = 4010 g

Density = mass / volume

7.86 = 4010 / volume

Volume = 4010 / 7.86

Volume = 510.17 cm³ 

hope this helps!

A student had two dilute, colorless solutions, HCl(aq) and NaOH(aq), which were at the same temperature. The student combined the solutions, and the reaction represented above occurred. Which of the following results would be evidence that a chemical reaction took place

Answers

Answer:

The reaction of an aqueous hydrochloric acid solution with an aqueous sodium hydroxide solution is represented by the neutralization chemical equation:

HCl(aq) + NaOH(aq) --> NaCl(aq) + H2O(l) + Energy

Explanation:

This is called a neutralization reaction, which is a reaction in which an acid and a base react to form water and a salt. This reaction involves the combination of H+ ions and OH- ions to generate water. pH equal to 7 is a neutralization of a strong acid and strong base. The neutralization of a strong acid and weak base will have a pH of less than 7, and conversely, the resulting pH when a strong base neutralizes a weak acid will be greater than 7.

When a solution is neutralized, it means that salts are formed from equal weights of acid and base. The amount of acid needed is the amount that would give one mole of protons (H+) and the amount of base needed is the amount that would give one mole of (OH-).

The production of sodium chloride and water is the indication that reaction took place.

  • The formation of sodium chloride and water would be evidence that a chemical reaction took place because new substances are formed from the reaction hydrochloric acid (HCl) and sodium hydroxide (NaOH).
  • When  hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the sodium of NaOH combine with chlorine of HCl produces sodium chloride (NaCl).
  • Whereas the hydrogen of HCl combine with hydroxide of NaOH so we can conclude that production of sodium chloride and water is the indication that reaction took place.
