How to tell if an equation is acidic or basic?

1 answer:

8 0

<span>Chemical equations are neither acidic nor basic, but you can evaluate the products of the reaction (and maybe the reactants too) and identify the existence of acids or bases which will indicate what kind of effects the reaction will have on the acidity. However, I'm not sure if you're asking the question you want to know the answer to, maybe you're wondering about balancing redox equations (which you do differently in acidic vs basic environments), in which case you'll need additional information beyond just an equation, but if the equation is redox and it's balanced just look for the presence of H+ ions or OH- ions on either side and that will tell you if it is acidic or basic (respectively), if neither is present, it'll be neutral.</span>

Hanna hypothesizes that granite is denser than sandstone. How can Hanna test her hypothesis?

kherson [118]

To test if the hypothesis is correct, a good way is to think of it this way:
Density = mass/volume, right?
Calculate the mass and volume of each and do the equation; this will test your hypothesis.
You will be left with the density of each. But, make sure that the sample sizes are the same (controlled variable) otherwise it will be an unfair test.

44.8% of a 250. mL acid solution is used in an experiment, what volume of acid (in mL) was used?

postnew [5]

Answer:

112 mL

Explanation:

The formula for percent by volume is

$\text{Percent by volume} = \dfrac{\text{Volume of solute}}{\text{Volume of solution}}\times 100 \, \%$

If you have 250 mL of a solution that is 44.8 % v/v,

$\begin{array}{rcl}44.8\, \% & = & \dfrac{\text{Volume of solute}}{\text{250 mL}}\times 100 \, \%\\\\44.8 \times \text{ 250 mL} & = & \text{Volume of solute} \times 100\\\text{Volume of solute} & = & \dfrac{44.8 \times 250\text{ mL}}{100}\\\\ & = & \textbf{112 mL}\\\end{array}$

Car manufacturers use radiation for which task?

Lilit [14]

ANSWER: B) drying paint

EXPLANATION: Car manufacturers use UV radiation to dry the paint o the vehicle. The high reflectivity of infrared radiation helps to keep the car interior cool. It also gives advantages over convection heating. It can provide both high intensity and low intensity heat and is a low cost heat source when compared in dollars per unit of energy consumed. The IR heating also doesn't penetrate deeply and apply heating only on the outer surface.

How many energy levels contain electrons in an atom of zirconium (Zr)?

ad-work [718]

<h3>Answer: five cause </h3>

The number of energy levels of zirconium is 5, and I know this because it is located in family five. Families are the rows across on the periodic table. The family number is always equal to the number of energy levels.Zirconium: properties of free atoms. Zirconium atoms have 40 electrons and the shell structure is 2.8.
