Answer:

The correct answers are sunlight is bent at a smaller angle and the electrical conductivity of seawater decreases.

Explanation:

In seawater, the refraction angle changes according to salinity and temperature, becoming higher when salt concentration increases and temperature decreases.

The conductivity of water depends on the amount of salt dissolved in it. The electric current is caused by the movement of electrically charged particles and in response to the forces acting on these particles due to an applied electric field. Conductivity increases as the amount of solids dissolved in water increases. So if salinity decreases, does salinity.

Give the spectator ions for the reaction that occurs when aqueous solutions of H 2SO 4 and KOH are mixed.

Sever21 [200]

Answer:

The spectator ions is: $K^+$ and $SO^{2-}_4$

Explanation:

The equation of reaction between H₂ SO₄ and KOH is:

$H_2SO_{4(aq)} + 2KOH _{aq} \to K_2SO_{4(aq)} +2H_2O _{(l)}$

Rewriting this equation as ionic;

$[2H^{+} + SO^{2-}_4 + 2K^+ +2OH^- \to 2K^+ SO_4^{2-} + 2H_2O ]$

Spectators ions are ions present on both sides of the ionic equation by the same quantity but do not take part in the net reaction.

Convert 27.7 kilometers to centimeters.

Stolb23 [73]

Answer:

The correct answer is - 2770000 cm.

Explanation:

1 kilometer = 1000 meter

1 meter = 100 centimeter

1 kilometer = 100*1000 cm

1 km = 100000 cm.

then,

27.7 kilometers = 2.77 × 10^6 centimeters

So, 27.7 kilometers = 27.7 × 100000

= 2.77 × 106 or 2770000 centimeters.

If there were an element above fluorine in the periodic table what phase would you expect it to be in (at room temp)?

AysviL [449]

If there were an element above fluorine, its state would be a gas. This is because fluorine is located in the non-metal section of the periodic table which can all be found as a gas at room temperature.

Which element has higher ionization energy? chlorine or carbon

PtichkaEL [24]

Answer:

chlorine has higher ionization than carbon

Explanation:

Chlorine is only one row below carbon, but it is three columns to the right in this case the IP of chlorine would be predicted to be greater than the IP of carbon.
