We first determine the complete reaction of the substances given above to tell whether precipitates are formed.

NaCl + NaBr  = no reaction
NaCl + Na2CO3 = no reaction
<span>NaCl + BaCl2  = no reaction</span>
<span>NaCl + HCl = no reaction 
</span>
From all the substances given, reaction cannot happen therefore no precipitates are formed.

If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume
Liula [17]

Answer:

<h3>The answer is 200 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}\\

From the question

mass = 150 g

density = 0.75 g/cm³

We have

volume =  \frac{150}{0.75}  \\

We have the final answer as

<h3>200 cm³</h3>

Hope this helps you

Determine whether the graph is that of a function by using the vertical-line test. If it is, use the graph to find (a) its domai
Ilia_Sergeevich [38]

Answer:

Following are the solution to this question:

Explanation:

If the draw a line perpendicular with y-axis thru the diagonal line check but it meets only one curved point, therefore the curve indicates a function not otherwise.  They draw a vertical line perpendicular to the y-axis there, it just intersects one more chart point, which is why a graph is a feature:

In point a:

\to Domain= [-\pi ,\pi ]\\\\\to Range = [-1,1]

In point b:

Its y-axis length cut also by understanding the benefits of y-interception and the x-axis length gives the x-intercept.  

\to y-intercept = 1\\\\\to x-intercept = \frac{\pi}{2} ,- \frac{\pi}{2} \\\\

In point C:

Every graph is y-axis symmetric because the left side of the column as well as the middle side of the graph is about the same.
