We have a solution of phosphoric acid (H3PO4) 100mL, concentration 3.0mol / L, they want to neutralize this acid, they use 250mL of potassium hydroxide. A. Write the reaction equation. B. Calculate the number of moles of phosphoric acid and potassium hydroxide used. C. Calculate the molecular concentration of the potassium hydroxide solution. (K = 39, P = 31, O = 16 H = 1)

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them  

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
