Based on the balanced equation, the molar ratio of CuCl2 to Al should be 3:2

1) The chemical equation is:
 

Al +  CuCl2 ---> Cu + AlCl3


2) You have to balance the equation to state the coefficients:


2Al + 3CuCl2 ---> 3Cu + 2Al Cl3


3) Now the coefficients tell you the molar ratios.

2 mol Al : 3 mol CuCl2 : 3 mol Cu : 2 mol AlCl3



4) The molar ratio of CuCl2 to Al is:


3 mol Cu Cl2 / 2 mol Al = 3/2 = 1.5

Cyanide and water react in a proton transfer reaction to form hydrogen cyanide and hydroxide
alukav5142 [94]

The proton transfer reaction between Cyanide and water can be written as; X^- + H2O -----> HX + OH^-

<h3>What is a proton transfer reaction?</h3>

A proton transfer reaction is one in which a proton is moved from one chemical specie to another.It is in fact and acid - base reaction in the Brownstead - Lowry sense.

The proton transfer reaction between Cyanide and water can be written as(Let the cyanide ion be shown as X);

X^- + H2O -----> HX + OH^-

Combustion of hydrocarbons such as undecane (_____) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's
____ [38]

Answer: Undecane, C11H24 is a liquid hydrocarbon from the alkane homologue ( family ).

Explanation:

All hydrocarbons burn in air to release H20 and CO2.

Combustion of hydrocarbons thus increases the percentage of CO2 present in the atmosphere which is not so good as CO2 is a greenhouse gas. Greenhouse gases produce the greenhouse effect. The green house effect is the warming effect produced when gases present in the atmosphere allow and retain the radiation from the sun to the earth. Examples of greenhouse gases are CO2, CH4, SO3, NO, CFCs. The greenhouse effect leads to an increase in the temperature of the earth subsequently leading to (I) melting of large amounts of ice at the poles causing flooding. (II) rapid evaporation of water from Earth’s surface. (III) decrease in crop yield.

Also, high concentration CFCs ( chlorofluorocarbons ), as widely used in aerosols, coolants and packaging foams, in the atmosphere depletes the ozone layer leading to global warming. In 1996 an international agreement was reached for a complete ban of CFCs and more countries are now going Green ( using alternative energy sources ) so as to minimize emissions of these greenhouse gases

A man weighing 75 kg takes 5 minutes to reach a height of 5 m when he climbs a staircase. What is his power?
Naddika [18.5K]

Answer: B. 12.25 W

please give brainliest!

Explanation:

1) Force = Weight = 75 x 9.8 = 735 N

2.)Work = Force x Height = 735 x 5 = 3675 J

3.)Power = Work / Time = 3675 / (5 x 60) = 12.25 W
