Please be specific.

Chemistry
reaction balanced equation. Al2C3 + O2 ----> CO2 + Al3 therefore 3Al2C3 + 9O2 = 9CO2 + 2Al3 so try to find the mass of CO2 from the equation, then n= m/M

chemistry
CO + 2H2 = CH3OH 2mol 1mol ?gr 45gr 45 x 2 = 90 grams hope i got it right for you

Math
seem right to me.

Numerical & Proportional Reasoning
first: $300US = 300x0.821774= 246.53euro. she spent 100euro, so she had 146.53 euro left going to Japan. then you can change 146.53 euro back to US dollar. 146.53 euro = (146.53/0.821774)=178.31US dollar then change US dollar to Yen, therefore 173.31 US= 173.31 x (110.565)= 19...

algebraic reasoning
have your grap on the y-axis represents the height, and the x-axis represents the time. when she goes down, draw a line going down according to the time and the elevation, and the line will go up when she goes up with the time given. for the total time will be 5min down, 5 min...

Algebra
-8x + 4y = -12 +8x +8x --- ---- 0 +4y = -12 + 8x divide both sides by 4 (4y)/4 = (-12)/4 +(8x)/4 y = -3 + 2x or y= 2x -3 good luck

math
y=mx + 2 means 2 is the y-intercept when x=0, m is the slope, if m>0, the line will go up to the right, (/) if m<0, the line will go down to the right(\) good luck
