Answer : The correct option is, (B) NaOH

Explanation :

Indicators : It is a substance that gives the visible sign by the color change of the chemical species like an acid or a base.

Universal Indicator : It changes color when mixed with an acid or base.

Universal Indicator turns red when it is added to a strong acid, it turns blue or purple when it is added to a strong base and it turns a yellowish-green when it is added to a neutral solution.

The pH range is, 1 to 14.

When the value of pH is less than 7 then the solution is acidic.

When the value of pH is more than 7 then the solution is basic.

When the value of pH is equal to 7 then the solution is neutral.

According to the pH chart, HCl is a strong acid whose pH is 1, saliva is also an acid whose pH is less than 7 that is 6.8. NaOH is a strong base whose pH is 14. The blood is slight basic in nature and the pH of blood is 7.4.

Hence, the strongest base is, (B) NaOH

Answer:

NaOH

Explanation:

HCl is a strong acid

Blood has a pH around 7.35, making it only slightly basic

Saliva has a pH around 6.7, making it slightly acidic

1.Convert 2.37 moles of Al(NO3)3 to grams.. Single choice.

aleksley [76]

Answer:

1. 504.8 g Al(NO3)3

2. 14.3 moles O2

Explanation:

g = moles x molar mass = 2.37 x 212.996 = 504.8 g Al(NO3)3

MM Al(NO3)3 = 212.996 g/mol

moles = mass : molar mass = 456.89: 32 = 14.3 moles O2

An agent of weathering where liquid water seeps into the cracks of rocks is called?

babunello [35]

Answer:

Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze. ... This specific process (the freeze-thaw cycle) is called frost weathering or cryofracturing.

OLEGan [10]

Answer:

T2=324.29k

Explanation:

V1=3.4L T1=25+273=298k

V2=3.7L T2=?

V1 V2

---- = ----

T1 T2

T2= V2×T1/V1

Which of the following is NOT true about ions? (1 point)

weeeeeb [17]

Answer:

When a cation forms, more electrons are transferred to it

Explanation:

Ions can either be cations (positively charged species) or anions (negatively charged species).

Cations are produced when atoms, typically metal atoms, lose their valence electrons to become positively charged.

Anions are produced when nonmetal atoms gain electrons to become negatively charged.

These definitions already eliminate the majority of choices: cations are positively charged ions. Anions are common among nonmetals.

Thinking about nomenclature, charges are represented by a superscript of a number with either a plus (for positive charges) or a minus (for negative charges).

It is false, however, that when a cation forms, electrons are transferred to it. In reality, cations lose electrons rather than gain.
