Answer:

They add to its hardness.

Explanation:

Hello,

Water in ecosystems are likely to have dissolved metallic cations such those alkalies and alkaline earth metals form when present in aqueous systems, in this manner, more specifically speaking, calcium ions promote the formation of unsoluble salts such as calcium carbonate, which lead to the increase of the water's hardness that accounts for such cation's content into the water. Therefore, among the following options:

A. They reduce its pH.

B. They decrease its salinity.

C. They add to its hardness.

D. They increase its acidity.

The correct is C. They add to its hardness.

Best regards.

What is the absorbance of the permanganate in the diluted waste solution?
Snowcat [4.5K]
<span>Not to be confused with tetration. This article is about volumetric titration. For other uses, see Titration (disambiguation). Acid–base titration is a quantitative analysis of concentration of an unknown acid or base solution. Titration, also known as titrimetry,[1] is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator[2] is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand[3] to determine concentration. The volume of titrant reacted is called titration volume</span>

Someone help me with this please, it’s overdue:(
Zolol [24]

Answer:

See explanation.

Explanation:

Hello there!

3. In this case, according to the given question, it turns out possible for us to say that any chemical formula, for an ionic compound, has the cation (positive) on the left and the anion (negative) on the right; thus, since Mg is a metal, which tends to lose electrons and become positively charged whereas the Cl is a nonmetal, which tends to gain electrons and become negatively charged, we have the following:

Mg^{2+}Cl^-\\\\Mg^{2+}Cl^-_2\\\\MgCl_2

4. In this case, since lithium is a metal, as well as magnesium, it is not possible for them to switch around their charges as they will not be bonded because they will be repelled rather than attracted because of their equal positive charges.

Regards!

What is the frequency, in hertz, of blue light having a wavelength of 4.25 x 10-?m? Your answer should be
Naddik [55]

Answer:

7.05*10^16(when wavelength =4.25*10^-9m)

Explanation:

c=wavelength *frequency (f)

i.e. f=c/wavelength =3*10^8/4.25*10^-9=7.05*10^16
