Help me!!!!!!!!!!!!!<br>what is the most important factor in determining climate
cestrela7 [59]

The correct answer is - latitude.

The latitude in many ways is the most important factor in determining the climate of a place. The reason for that is mostly the shape of the planet, which doesn't allow the Sun light to be equally distributed on all of its surface. The lower the latitude, the more direct and more concentrated the Sun light, thus the place will be warmer. The higher the latitude, the sharper the angle of the fall of the Sun light, thus more dispersed Sun light, which will result in a much colder climate.

A 4-g mass of NaOH is dissolved in 5mL of water.
lapo4ka [179]
Molar mass NaOH = 40.0 g/mol

Volume in liters of solution :

5 mL / 1000 => 0.005 L 

number  of moles :

4 / 40 => 0.1 moles

M = n / V

M = 0.1 / 0.005

 = 20 mol/L or 20 M

hope this helps!

A gas has a volume of 200. mL at 350. mm Hg. What will its volume be if the pressure is changed to 555. mm Hg
mrs_skeptik [129]

Answer:

The final volume when pressure is changed is 126.1mL

Explanation:

Based on Boyle's law, in a gas the volume is inversely proportional to its pressure when temperature remains constant. The equation is:

P₁V₁ = P₂V₂

<em>Where P is pressure and V volume of 1, intial state and 2, final state.</em>

<em />

Computing the values of the problem:

350mmHg*200mL = 555mmHgV₂

126.1mmHg = V₂

<h3>The final volume when pressure is changed is 126.1mL</h3>

A three-step mechanism has been suggested for the formation of carbonyl chloride: Step 1: Cl2 → 2 Cl Step 2: Cl + CO → COCl Step
ladessa [460]

Answer:

COCl species is an intermediate in the mechanism.

Explanation:

Intermediates are those chemical species which only appears for a short time in a course of a chemical reaction. They act as product and reactant during the reaction. Also they do not appear in overall chemical reaction.

Step 1: Cl_2\rightarrow 2 Cl

Step 2: Cl + CO\rightarrow COCl

Step 3: COCl + Cl_2\rightarrow COCl_2 + Cl

Overall reaction :

2Cl_2+CO\rightarrow COCl_2+2Cl

As we can see that all the chemicals are present in the overall reaction beside COCl.

COCl species is an intermediate in the mechanism.
