Answer:
Explanation:
The equation of above line , y = 0.0005x+ 0.458
This can be compared with y = mx+c
Hence slope, m = 0.0005 and Y-intercept, c = 0.458
Or it can be plotted manually where straight line has to be drawn touching maximum number of data points. After drawing a straight linear line, we need to take any two points from the straight line and slope is calculated
Slope,
and y -intercept is calculated using extraplotting backwards such that it touches the Y-axis. the point where straight line touches Y-axis is Y-intercept (c).

Answer:
D all above yes I think it's all above
Equation of reaction
Hcl+NaoH-->Nacl+H2O
1:1
Using the formula CaVa/CbVb=na/nb
Ca(Concentation of acid)= 0.100M
Cb(Concentration of base)=0.200M
Va=?
VB=50.00ml
na=1
nb=1
from the formula
Va= CbVbna/Canb
Va= 0.2*50*1/0.1*1
=10/0.1=100ml
Therefore volume of acid = 100ml
Answer:
Elements
Explanation:
Each kind of atom is an element. Elements are pure substances that cannot be broken down into simpler substances by ordinary chemical means.
We know that
1 calorie = 4.184 Joules
so let us convert the joules to calories first
1 Joule = 1 / 4.184 Cal
150000 = 150000 / 4.184 Cal = 35850.86 Cal
Now in case of food articles
one calorie = 1 Kcal
Therefore on food label it will = 35.851 Cal
