Answer:
No.
Explanation:
During chemical reaction, atomes cannot be created or destroyed, they can only react together to form <em>E</em><em>l</em><em>e</em><em>m</em><em>e</em><em>n</em><em>t</em><em> </em>or <em>C</em><em>o</em><em>m</em><em>p</em><em>o</em><em>u</em><em>n</em><em>d</em><em> </em>at the <em>P</em><em>r</em><em>o</em><em>d</em><em>u</em><em>c</em><em>t</em><em> </em>side.
Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The equation to describe the decay is
Nt=N0(1/2)
where N0 is the initial quantity, Nt is the remaining quantity after time t, t1/2 is the half-time. So work out the equation, t1/2 = t (-ln2)/ln(Nt/N0) = 11.5*(-ln2)/ln(12.5/100) = 3.83 days
A = change in velocity / time
so change in velocity = 13-7 = 6
so 6/1 =6:
acceleration = 6m/s^2
Answer with explanation:
1) general word equation=acid + metal= salt + hydrogen gas
chemical/balanced equation= 2HCl+Mg=MgCl2+H2
2)The gas thus formed is an effervescent carbon di oxide when calcium chloride reacts with hydrochloric acid. the carbon di oxide gas also acts as an extinguisher for fires. Hence the burning candle is extinguished.
Answer:
Equal parts are needed to make glucose and oxygen. The excess oxygen is released into the air
