I saw this question in class today

Explanation:

Answer:

 H₃PO₄    +    3NaBr  →    3HBr        +    Na₃PO₄

Explanation:

The unbalanced reaction expression is given as:

            H₃PO₄    +    NaBr  →    HBr        +    Na₃PO₄

We need to balance the expression.

Let us assign variable a, b, c and d and solve mathematically;

       aH₃PO₄    +    bNaBr  →    cHBr        +    dNa₃PO₄

Conserving H : 3a  = c

                   P:   a  = d

                   O :  4a  = 4d

                   Na:   b = 3d

                    Br:    b  = c

Let a  = 1, c  = 3, d  = 1, b  = 3

So:

     H₃PO₄    +    3NaBr  →    3HBr        +    Na₃PO₄

Simplify the expression.

Answer:

This is called negative adsorption. Hence if the concentration of the adsorbate is less on the surface of the adsorbent than in the bulk, it is known as negative adsorption.

Answer:

Chlorine and sodium iodide. (see options attached)

Explanation:

Options:

(A) bromine and sodium chloride (B) bromine and sodium fluoride (C) chlorine and sodium fluoride (D) chlorine and sodium iodide

In the reactivity series, chlorine would displace all the other halogens down the group. The order goes:

The order of reactivity is chlorine > bromine > iodine.

Of all the halogens, iodine is the darkest in colour. Hence, the most likely mixture to give off dark coloration after displacement reaction would be that of chlorine and sodium iodide.

I hope this explanation was easy to understand.

Answer:

So the answer is gonna be how to get enough energy for your daily life

Explanation:

Sometimes the human body cant get enough energy from the food and protein the food gives out.

Answer:

C. Yes, if each sample contains 6.02 x 10²³ atoms.

Explanation:

It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.

6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.

A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.

Answer:

Answer: C (Yes, if each sample contains 6.02 x 1023 atoms.) for all the edge speed runners ;)

Got it right on the test review edge 2022

Answer:

HCl

Explanation:

Given data:

Mass of Zn = 50 g

Mass of HCl = 50 g

Limiting reactant = ?

Solution:

Chemical equation:

Zn + 2HCl      →     ZnCl₂ + H₂

Number of moles of Zn:

Number of moles = mass / molar mass

Number of moles = 50 g/ 65.38 g/mol

Number of moles = 0.76 mol

Number of moles of HCl:

Number of moles = mass / molar mass

Number of moles = 50 g/ 36.5 g/mol

Number of moles = 1.4 mol

Now we will compare the moles of Reactant with product.

                 Zn         :          ZnCl₂

                  1           :             1

                 0.76     :           0.76

                Zn         :             H₂

                  1           :             1

                 0.76     :           0.76

               HCl         :          ZnCl₂

                  2           :             1

                 1.4         :           1/2×1.4 = 0.7

                HCl         :             H₂

                  2           :             1

                 1.4         :           1/2×1.4 = 0.7

Less number of moles of product are formed by HCl it will act limiting reactant.

Answer:

The answer is, in fact, Calcium Nitrate. I even looked it up to make sure, and according to PubChem, it is Calcium Nitrate. I suggest asking your teacher what this question is trying to ask because if it says it is not Calcium Nitrate, someone got it wrong.

Explanation:

The only other name I can think of, though, is Calcium Dinitrite.

Answer:

See explanation and image attached

Explanation:

Lewis structures dot structures that show the number of valence electron in a molecule. Sometimes, we show bonded electrons using a single line as in the image attached.

Two images are shown. They are the both resonance structures of diazene. The both structures only differ in the arrangement of electrons as we can see from the image.

Answer:

2 : 2

Explanation:

The balanced chemical equation is given as:

            2K   +     Cl₂   →    2KCl

From the balanced reaction equation, we can conclude that;

Therefore, the mole ratio is 2:2 or 1:1 in the simplest form.

Answer: The answer is c

Explanation:

The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.

Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of the earth shields its people by absorbing dangerous sun rays and preserving a constant temperature. It protects Earth from many space hazards and enables life there. As a result, it is crucial for regulating climate and a source of life on planet.

The majority of the infrared energy from the Sun is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds, creating the greenhouse effect. This causes the lower atmosphere and the Earth's surface to warm.

Thus, the gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.

mass Ag = 59.5 g

Given

64 g of Ag2O

Required

Mass of Ag

Solution

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

mass of Ag in Ag2O :

= ((2 x Ar Ag)/molar mass Ag2O )x mass Ag2O

[tex]\tt mass~Ag=\dfrac{2.Ar~Ag}{MW~Ag_2O}\times mass~Ag_2O[/tex]

Ar Ag : 107,8682 g/mol

MW Ag₂O = 231,735 g/mol

Input the value :

mass Ag = ( (2 x 107,8682 g/mol )/ 231.735) x 64 g

mass Ag = 59.5 g

Or we can use reaction

2Ag₂O ⇒ 4Ag + O₂

mol Ag₂O :

= 64 : 231.735

= 0.276

mol Ag :

= 4/2 x moles Ag₂O

= 4/2 x 0.276

= 0.552

mass Ag :

= 0.552 x 107,8682 g/mol

= 59.54 g

Answer:

0.16 moles of Ar

Explanation:

One mole is equal to 6.022×10^23 atoms
