Answer:
35.9 grams
Step-by-step explanation:
We use the formula:
Where
q is heat released
m is mass
C_p is the constant 2.44
ΔT is change in temperature
We put the info in the formula and solve for m (mass):
The mass of ethanol is 35.9 grams
Answer:
B
Step-by-step explanation:
For a line to be parallel it must have the same slope
6x-2y=-5
+5 +5
6x-2y+5 = 0
+2y +2y
6x+5 =2y
/2 /2
3x+5/2=y So the slope is 3 and we know it can only be either B or D
Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D
B. -2= 21-23 TRUE
D. -2 = 21+ 23 FALSE
So the answer is B
The equation is false because the real answer is z5/4. The variable doesn't just disappear.
