why would a pregnant mother need more calcium than a woman her age that is not pregnant?​

Answers

Besides building teeth and bones, calcium also keeps your blood and muscles moving and helps your nerves send messages from your brain to the rest of your body. Your body can't make calcium, so you need to get it from food or supplements. While you're pregnant, try to get at least 1,000 mg of calcium every day.

Calcium is a vital mineral. Your body uses it to build strong bones and teeth. calcium is also needed for your heart and other muscles to function properly

Volume of 8.625 g of sulphur di oxide at RTP in cm3

Answers

Answer:

The volume of 8.625 g of sulphur dioxide at RTP is approximately 3,230.84 cm³

Explanation:

The question requires the determination of the volume occupied by the gas based on the molar volume of a gas at STP

The given parameters of the sulphur dioxide, SO₂, gas are;

The mass of the given SO₂ gas = 8.625 g

The molar mass of SO₂ = 64.07 g/mol

The number of moles, 'n', in the given sample of SO₂ gas = Mass of SO₂/(Molar Mass of SO₂)

∴ The number of moles of SO₂ in the gas sample = 8.625 g/(64.07 g/mol) ≈ 0.134618386 moles

The molar volume of a gas at RTP is approximately 24 dm³/mole

24 dm³ = 24,000 cm³

∴ The molar volume of a gas at RTP is approximately 24,000 cm³/mole

The volume occupied by a gas at RTP = (The number of moles of the gas) × (The Molar Volume of a gas at RTP)

∴ The volume occupied by the 8.625 g of SO₂ gas at RTP = 0.134618386 moles × 24,000 cm³/mole ≈ 3,230.84 cm³

The volume occupied by the 8.625 g of SO₂ gas at RTP ≈ 3,230.84 cm³.

2C3H7OH + 9O2 -> 6CO2 + 8H2O

How Many Moles of CO2 can be produced by reacting 6 moles of C3H7OH with oxygen?

Answers

Answer:

Up to [tex]18\; \rm mol[/tex] [tex]\rm CO_2[/tex].

Explanation:

The equation for this reaction: [tex]2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O[/tex] is indeed balanced.

Notice that the coefficient of [tex]\rm C_3 H_7 OH[/tex] is [tex]2[/tex] while that of [tex]\rm CO_2[/tex] is [tex]6[/tex].

Therefore, each unit of this reaction would consume [tex]2[/tex] units of [tex]\rm C_3H_7OH[/tex] while producing [tex]6[/tex] units of [tex]\rm CO_2[/tex]. In other words, this reaction would produce three times as much [tex]\rm CO_2\![/tex] as it consumes [tex]\rm C_3H_7OH\![/tex].

If all that [tex]6\; \rm mol[/tex] of [tex]\rm C_3H_7OH[/tex] molecules are actually consumed through this reaction, three times as many [tex]\rm CO_2[/tex] molecules would be produced. That corresponds to [tex]3 \times 6\; \rm mol = 18\; \rm mol[/tex] of [tex]\rm CO_2\![/tex] molecules.

2.7 x 10-2 grams of Pb(C2H302)4 are dissolved to make 3.5 mL of
solution. What is the molarity?
Your Answer

Answers

Answer:

The molarity is 0.0174 [tex]\frac{moles}{liter}[/tex]

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.

[tex]Molarity=\frac{number of moles of solute}{volume of solution}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case, being the molar mass of compound Pb(C₂H₃O₂)₄ equal to 443.38 g / mol, then the following rule of three can be applied: if 443.38 grams are contained in 1 mol, 2.7*10⁻² grams in how many moles they are present?

[tex]amount of moles=\frac{2.7*10^{-2} grams*1 mol}{443.38 grams}[/tex]

amount of moles= 6.09*10⁻⁵ moles

Being 1,000 mL= 1 L, then 3.5 mL= 3.5*10⁻³ L

So:

[tex]Molarity=\frac{6.09*10^{-5} moles}{3.5*10^{-3} L}[/tex]

Solving:

Molarity=0.0174 [tex]\frac{moles}{liter}[/tex]

The molarity is 0.0174 [tex]\frac{moles}{liter}[/tex]

Neon is used in lighting advertising displays.

Which statement can be applied to an atom of neon?

A The atom has the same electron arrangement as Cl– ion.
B The atom has two more electrons than an atom of oxygen.
C The atom has the same number of outer electrons as an atom of helium.
D The atom has the same number of electrons as a Ca2+ ion.

Answers

Answer:

B. The atom has two more electrons than an atom of oxygen.

Explanation:

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.

This ultimately implies that, an [tex] O^{2-} [/tex] atom contains the same number of electrons as an atom of neon.

Hence, a neon atom has two more electrons than an atom of oxygen.

Additionally, Neon is used in lighting advertising displays.


Help out please????

Answers

Answer:

B. X= Elements, Y= Compounds

Explanation:

An element is a substance that is made up of only one type of atom. The atoms of an element can combine together chemically to form a molecule but can still exist as an individual atom e.g. Hydrogen atom; H can form molecule H2. Since only one atom makes up an element, its electrons act independently.

Compounds, on the other hand, are substances that are made up of more than one type of atom chemically combined. A compound can only exist as a molecule because it always contains more than one atom bonded together. However, since more than one atom are involved in the chemical bond that holds them together, electrons are shared with other atoms. Example of a compound is H20 containing atoms of hydrogen and oxygen that are chemically combined.
