The first three terms of the sequence -8,x,y,72... form an arithmetic sequence, while the second, third and fourth terms form a geometric sequence. Determine x and y.
Some metallic carbonates, when heated, decompose to form the metal oxide and carbon dioxide, so: Li2CO3 ---> Li2O + CO2
yes you always need to balance the equation.It's in the law of conservation of mass..
2Li2CO3 -> 4Li+2CO2+O2
I NEED HELP ASAP WITH SCIENCE PLEASE IT'S IMPORTAN
Mitochondria are involved in aerobic cellular respiration. Fermentation is part of the process of cellular respiration. In the presence of oxygen, further processing of the fermentation products will occur in the mitochondria, yielding more ATP. Without oxygen -- well, ferment...
a. 4(-2)^2 + 3(-2) + 2 = 12 b. 4(-x)^2 + 3(-x) + 2 4x - 3x + 2 =x + 2 c. -[ 4x^2 + 3x + 2] = -4x^2-3x-2 d.4(x+h)^2 + 3(x+h) +2 (4x^2 + 8xh + 4h^2) + 3x + 3h + 2 = 4x^2 + 8xh + 4h^2 + 3x + 3h + 2 I'm not sure about the last part.
oh yes.. sorry:)
if we convert it into hours: in 1 hour there are 60 min so, 105 min ( 1hr/ 60 min) it's 1 hr. and 75 min. maybe you can ask your teacher about that..
