100% no.

Blood cells and white cells, for example, have different colors.

White cells are larger with not much of them while blood cells are opposite.

They are in our body

5.00 ml of commercial bleach was diluted to 100.0 ml. 25.0 ml of the diluted sample was titrated with 4.56 ml of 0.100 m s2o3 2-

aev [14]

The solution would be like this for this specific problem:

4 NaOCl + S2O3{2-} + 2 OH{-} → 2 SO4{2-} + H2O + 4 NaCl

(0.00456 L) x (0.100 mol/L S2O3{2-}) x (4 mol NaOCl / 1 mol S2O3{2-}) x (100.0 mL / 25 mL) x 
(74.4422 g NaClO/mol) = 0.54313 g

(5.00 mL) x (1.08 g/mL) = 5.40 g solution

(0.54313 g) / (5.40 g) = 0.101 = 10.1%

So, the average percent by mass of NaClO in the commercial bleach is 10.1%.

What's a good way to remember Newtons Laws?

allsm [11]

Fist law of motion is piece of cake
Things don’t move to get a shake 

Second law of ,motion 
Is all about the force 
If something hits hard 
Then the object takes that force 

Third of motion is to give you satisfaction 
For ever forth mate there is opposite reaction

Hope this helps. :)

Which term describes this reaction? upper c upper h subscript 3 upper b r (a q) plus upper o upper h superscript minus (a q) rig

Veronika [31]

The reaction is a substitution reaction since bromide ion was replaced by hydroxide ion.

<h3>What is a chemical reaction?</h3>

A chemical reaction is a change which results in a the permanent rearrangements of the atoms and constituents of a substance such that new substances are formed.

The given reaction is a as follows:

$CH_3Br (aq) + OH^{-} (aq) \rightarrow CH_3OH (aq) + Br^{-} (aq) \\$

Bromide ion was replaced by hydroxide ion.

Therefore, the reaction is a substitution reaction.

what is the point of intersection when the system of equations below is graphed on the coordinate plane -x+y=4 6x+y=-3

Ilia_Sergeevich [38]

Answer:

POINTS OF INTERSECTION ARE:

x = -1

y = 3

coordinates : (-1,3)

Coordinates :

Explanation:

Condition for intersecting lines

$\frac{a_{1}}{a_{2}}\neq\frac{b_{1}}{b_{2}}$

here

a1 ,a2 = coefficients of x (a1 = -1 , a2 = 6)

b1 ,b2 = coefficients of y(b1 = 1 , b2 = 1)

$frac{-1}{6}\neq\frac{1}{1}\neq\frac{1}{1}$

Calculation :

Here substitution method is used : Value of y from eq (1) is substitued in equation (2)

-x + y = 4

y = 4 + x.............(i)

put value of x in equation (2)

6x + y = -3

6x + 4 + x = -3 ( from i)

7x = -3 - 4

7x = -7

x = $frac{-7}{7}$

x = -1

using equation(i)

y = 4 + (-1)

y = 4 - 1

y = 3

Check:

The values of x and y should satisfy equation (1) and (2)

for equation 1

-x+y =4

= -(-1) + 3

= 1 + 3

= 4

Hence coordinates satisfy equation 1
