A = change in velocity / time
so change in velocity = 13-7 = 6
so 6/1 =6:
acceleration = 6m/s^2
Answer:a line or a circle but i think circle
Explanation:
Answer:
When cosmetics companies use chemicals to make their products, they could dump their waste into rivers and oceans, causing water pollution to occur. The wildlife that lives in these habitats will probably die from them, causing some species to die out and become extinct.
Explanation:
Also, greenhouse gases could be released into the atmosphere, which would cause global warming.
Answer:
165.5 g of CO2
Explanation:
We must first put down the balanced reaction equation:
C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H2O(g)
From the reaction equation, one mole of butane occupies 22.4 L hence we can establish the stoichiometry of the reaction thus:
22.4 L of butane created 174 g of CO2
Therefore 21.3 L of butane will create 21.3 × 174/22.4 = 165.5 g of CO2
Answer:
When dissolved in water, acids donate hydrogen ions (H+). Hydrogen ions are hydrogen atoms that have lost an electron and now have just a proton, giving them a positive electrical charge. ... The H+ ions in the acid join with and are neutralized by the OH- ions of the base to form H2O.
