I think the correct answer from the choices listed above is option A. When you drink milk of magnesia for an upset stomach, most likely, it would raise the pH in your body since it reacts with the acid inside reducing the amount of acid. Hope this answers the question.

Answer:

It raises the pH of your stomach.

Explanation:

Milk of magnesia raises the pH of your stomach. This is because the pH of your acidic stomach is well below 7. Adding something with a high pH (a base) will raise the pH back to where it should be.

Calculate the solubility of o2 in water at a partial pressure of o2 of 120 torr at 25 ̊c. the henry's law constant for o2 at 25

Vladimir79 [104]

Answer:

1) 2.054 x 10⁻⁴ mol/L.

2) Decreasing the temperature will increase the solubilty of O₂ gas in water.

Explanation:

1) The solubility of O₂ gas in water:

We cam calculate the solubility of O₂ in water using Henry's law: Cgas = K P,

where, Cgas is the solubility if gas,

K is henry's law constant (K for O₂ at 25 ̊C is 1.3 x 10⁻³ mol/l atm),

P is the partial pressure of O₂ (P = 120 torr / 760 = 0.158 atm).

Cgas = K P = (1.3 x 10⁻³ mol/l atm) (0.158 atm) = 2.054 x 10⁻⁴ mol/L.

2) The effect of decreasing temperature on the solubility O₂ gas in water:

Decreasing the temperature will increase the solubilty of O₂ gas in water.

When the temperature increases, the solubility of O₂ gas in water will decrease because the increase in T will increase the kinetic energy of gas particles and increase its motion that will break intermolecular bonds and escape from solution.

Decreasing the temperature will increase the solubility of O₂ gas in water will because the kinetic energy of gas particles will decrease and limit its motion that can not break the intermolecular bonds and increase the solubility of O₂ gas.

How many formula units make up 36.0 g of magnesium chloride (MgCl2)?

zalisa [80]

Answer: There are $2.29\times 10^{23}$ formula units

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{36.0g}{95g/mol}=0.38moles$

1 mole of $MgCl_2$ contains = $6.023\times 10^{23}$ formula units

Thus 0.38 moles of $MgCl_2$ contains = $\frac{6.023\times 10^{23}}{1}\times 0.38=2.29\times 10^{23}$ formula units

Thus there are $2.29\times 10^{23}$ formula units

Carbon dioxide is a molecule made up of a single carbon atom double bonded to two oxygen atoms. The electrons are shared equally

wolverine [178]

Answer:

The type of bonding does carbon dioxide have is covalent bonding.

Explanation:

There are 2 broadly types of chemical bonds present:

1. Covalent bond: This bond is present when there is sharing of electrons between two elements.

2. Ionic bond: This type of bond is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.

We are given that a carbon atom is double bonded to two oxygen atoms. Carbon and oxygen both are non-metals and hence, the bonds between them will be purely covalent in nature.

Also, the valency of the carbon atom is 4. Thus, in the given case, the carbon atom is bonded to 2 oxygen atoms via double bonds. Thus, they all complete their octet by sharing the electrons.

Hence, the type of bonding does carbon dioxide have is covalent bonding.
