Just pay attention in school big bones, stop asking people because if they mislead you that will not be good for you're college education.
I think the correct answers from the choices listed above are the first and the last options. It would be helium that is the lightest monoatomic element and that an<span>tacid tablets neutralize stomach. Hope this answers the question. Have a nice day.</span>
Answer:
a. 1/3
In the picture- D. 4
Explanation:
The product of the gradients of perpendicular lines =-1
m1m2=-1
Given an equation of a line in the form y=mx+c, m is the gradient of the line.
For y= -3x-9, m=-3
m1m2=-1
-3×m2=-1
m2=1/3
The gradient of the perpendicular line is 1/3
For the question in the picture, y=-1/4x-9, m=-1/4
m1×m2=-1
-1/4m2=-1
m2=4
The slope of the line perpendicular to y=-1/4x-9 is 4
Answer: The difference between rapid combustion and spontaneous combustion...
Explanation:
Rapid combustion is a form of combustion, otherwise known as a fire, in which large amounts of heat and light energy are released, which often results in a flame.Whereas spontaneous combustion is the ignition of organic matter (e.g. hay or coal) without apparent cause, typically through heat generated internally by rapid oxidation.
The molar concentration of the solution is 1.55 mol/L.
1. Convert grams to moles.

2. Convert millilitres to litres

3. Calculate the molar concentration (c)
