U.S. Census Bureau changed the way it records information about relationships by increasing the number of relationship categories to include same-sex partner options and is denoted as option B.

<h3>What is Relationship?</h3>

This is a close connection between people and is characterized by physical or emotional intimacy.

There has been changes in the way U.S. Census Bureau records information is recorded in this aspect by  increasing the number of relationship categories for inclusiveness of other types of people such as those who have same-sex partners and so on.

This is therefore the reason why option B was chosen as the correct choice.

Answer:

H₂O + CO₂      →    H₂CO₃

Option D is correct.

Law of conservation of mass:

According to this law, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Now we will apply this law to given chemical equations:

A) H₂ + O₂   →    H₂O

There are two H and two O atoms present on left side while on right side only one O and two H atoms are present so mass in not conserved. This option is incorrect.

B) Mg + HCl   →   H₂ + MgCl₂

In this equation one Mg, one H and one Cl atoms are present on left side of equation while on right side two H, one Mg and two chlorine atoms are present. This equation also not follow the law of conservation of mass.

C) KClO₃      →     KCl + O₂

There are one K, one Cl and three O atoms are present on left side of equation while on right side one K one Cl and two oxygen atoms are present. This equation also not following the law of conservation of mass.

D)  H₂O + CO₂      →    H₂CO₃

There are two hydrogen, one carbon and three oxygen atoms are present on both side of equation thus, mass remain conserved. This option is correct.

Outline how fresh water could be extracted from salt water if fresh water was no longer available.
leva [86]

You can boil the salt water. The water will evaporate while the salt will be left behind because it's a solid. Salt has a much higher boiling point than water (2,575° F), so that's why it won't evaporate with the water.

Which of the following is the correct wedge and dash conformation for the following Newman projection?
kakasveta [241]

We have that  the correct wedge and dash conformation for the following Newman projection is

IV

From the Diagrams above

Two CH_3 groups points on opposite sides in plane

Two Br are on same side  of plane

Two H also on same side of the plane so the plausible  structure is IV

Therefore

The Correct option is IV

What is the amount of energy for a photon that has a 125 cm wavelength
Lera25 [3.4K]

Answer:

1.59 x 10⁻²⁵ J.

Explanation:

  • The energy of a photon is calculated Planck - Einstein's equation:

E = h ν , where

E is the energy of the photon,

h is  Planck's constant <em>(h = 6.626  x 10 ⁻³⁴ J.s)</em>

ν  is the frequency of the photon

  • There is a relation between the frequency (ν ) and wave length (λ).

λ.ν = c,

where c is the speed of light in vacuum (c = 3 .0 x 10 ⁸ m/s).

λ = 125 cm = 1.25 m.

<em>Now, E = h.c/λ.</em>

∴ E = h.c/λ = (6.626  x 10 ⁻³⁴ J.s) (3 .0 x 10 ⁸ m/s) / (1.25 m) = 1.59 x 10⁻²⁵ J.
