Calculate the co, emissions from the combustion of a kilogram of (a) methane and (b) diesel to verify the numbers in table 1.1. problem 1.3 the 2014 ford focus bev with a 24 kwh battery pack has upstream emissions of 68 gco, km in los angeles, 162 gco, km in detroit, and 118 gco,/km as an average in the usa. the gasoline 2.0 l'automatic 2014 ford focus has upstream emissions of 221 gco/km. how many kilometers must be driven for an electric ford focus to result in lower carbon emissions than the gasoline ford focus in (a) los angeles, (b) detroit, and (c) the usa, if the cradle-to-grave emissions of co, for the electric car and gasoline car are 10,300 kg and 7,500 kg, respectively. if each car is driven for the usa annual average of 21,700 km per year over 8 years, determine the combined total for the cradle-grave and tailpipe and upstream emissions for the three locations using electric and gasoline. norway has electricity emissions of about 50 times less than the usa, or about 2.5 gco,/km. what are the combined cradle-grave and upstream emissions if the bev is driven in norway for 21700 km per year over 8 years a representative hev has cradle-to-grave emissions of 7,500 kg and total emissions of 118 gco2/km. determine the combined total for the cradle- to-grave and tailpipe and upstream emissions for the various locations us ing the electric, hybrid and gasoline vehicles when driving 12,000 km per year over eight years.

the atomic mass is the bottom number on the element.

-steel jelly

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

the answer is 0.8m.
