Which type of reaction is described by the following equation Na2O (s) + 2CO2 (g) + H2) (g) Produces 2 NaHCO3 (s)

Answers

Answer 1

Answer:

If the reaction is going from left to right it would be synthesis, if going right to left it would be decomposition.

Explanation:

Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)

Left Side

Na = 2

O = 6

C = 2

H = 2

Right Side

Na = 2

O = 6

C = 2

H = 2

Ok so is balanced already, though initial equation in question had an error in regards to the left hand side the ) should have been an O.

Hmm

Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)

If it was going from right to left would be decomposition

But going from left to right it would be synthesis

What is the energy of light with a wavelength of 652 nm? (The speed of light in a vacuum is 3.00 x 108 m/s, and Planck's constant is 6.626 x 10-34 J·s.)
O A 3.05 x 10-²⁸ j
O B. 3.28 x 10¹⁸ j
O C. 3.05 x 10-¹⁹ j
D. 3.28 x 10²⁷ j

A and C have negative exponents pleas help me​

Answers

Answer:

C. 3.05 x 10⁻¹⁹ J

Explanation:

Given;

wavelength of the light, λ = 652 nm = 652 x 10⁻⁹ m

speed of light, c = 3.00 x 10⁸ m/s

Planck's constant, h = 6.626 x 10⁻³⁴J·s

Energy of electromagnetic wave is calculated as;

E = hf

where;

f is frequency of the light wave

f = c / λ

[tex]E = hf = h\frac{c}{\lambda} \\\\E = \frac{hc}{\lambda} \\\\E = \frac{6.626*10^{-34}*3*10^8}{652*10^{-9}} \\\\E = 3.05*10^{-19} \ J[/tex]

Therefore, the energy of the light is 3.05 x 10⁻¹⁹ J

The correct option is "C"

C. 3.05 x 10⁻¹⁹ J

Answer:

Option C. 3.05 x 10¯¹⁹ J

Explanation:

Step 1:

Data obtained from the question.

wavelength (λ) 652 nm = 652x10^–9m

Velocity of light (v) = 3.00x10^8 m/s

Planck's constant (h) = 6.626x10^-34J·s

Step 2:

Determination of the frequency of the light.

The frequency can be obtained as follow

v = λf

3x10^8 = 652x10^–9 x f

Divide both side by 652x10^–9

f = 3x10^8 / 652x10^–9

f = 4.6x10^14s¯¹

Step 3:

Determination of the energy of the light wave.

This can be obtained as follow:

Planck's constant (h) = 6.626x10^-34J·s

Frequency (f) = 4.6x10^14s¯¹

Energy (E) =..?

E = hf

E = 6.626x10^-34 x 4.6x10^14s¯¹

E = 3.05 x 10¯¹⁹ J

Baking soda, NaHCO3, can be commercially produced during a series of chemical reactions called the Solvay process. In this process, NH3(aq), NaCl(aq), and
other chemicals are used to produce NaHCO3(s) and NH Cl(aq).
To reduce production costs, NH3(aq) is recovered from NHCl(aq) through a different series of reactions. This series of reactions can be summarized by the
overall reaction represented by the unbalanced equation below.
NHACH(aq) + Ca(s) - NH3(aq) + H20() + CaCl(aq)
Balance the equation below for the overall reaction used to recover NH3(aq), using the smallest whole-number coefficients.

Answers

Answer:

CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)

Explanation:

The solvay process is an important process in the chemical industry. In this process, ammonia gas is first dissolved in concentrated brine to form a mixture known as ammoniacal brine. This solution is made to trickle down the tower. A counter stream of carbon dioxide is forced up the tower. The two substances react to form sodium hydrogen trioxocarbonate IV. This substance is only slightly soluble and separates out as a solid sludge. The product is now dried and heated to give sodium trioxocarbonate IV.

The overall reaction of the process can be given as;

CaO(s) + 2NH4Cl(aq) -------> CaCl2(aq) + H2O(l) + 2NH3(g)

Calcium chloride is merely a by-product.

Values for the molar mass of nitrogen, oxygen, and nitrogen dioxide molecules are given in the table below. What mass of nitrogen dioxide molecules is formed when 1 mole of nitrogen reacts with 2 moles of oxygen and forms nitrogen dioxide? Choices: A). 92.02g B). 46.01g C). 23.00g D) 2.00g

Answers

Answer:

A). 92.02g

Explanation:

Equation of the reaction;

N2 (g)+ 2O2(g)------> 2NO2(g)

Note that the balanced reaction equation is the first step in solving any problem on stoichiometry. Once the reaction equation is correct, the question can be easily solved.

Reaction of one mole of nitrogen gas with two moles of oxygen gas yields two moles of nitrogen dioxide.

Mass of two moles of nitrogen dioxide= 2[14 + 2(16)] = 2[14+32]= 2[46]= 92 gmol-1

Therefore; Mass of two moles of nitrogen dioxide is 92

An experimental procedure says to accurately weigh approximately 1 g of

O 0.99

Answers

Answer:

1.0456 g and 0.9811g

Explanation:

The measurements that are consistent with the approximate 1 g instruction would be 1.0456 g and 0.9811g.

Analytical balance generally weighs to an accuracy of 4 decimal places. Hence, every other option that is short of being in 4 decimal places is incorrect.

Also, 1.0456 g and 0.9811g when approximated to the nearest whole number give 1 g.

Answer:

C.ratio of elements in the compound.

Explanation:

A compound is a substance that constitutes two or more elements in a defined proportion. A chemical compound is different from another compound in what it contains i.e. elements. A chemical formula shows the elements contained in a specific compound. For example, the chemical formula of sodium chloride (NaCl) shows us that it contains Sodium (Na) and Chlorine (Cl) elements as represented by symbols.

In addition to this, a chemical formula also shows the ratio of each element that makes up the compound. An element can have more than one atom in a compound. For example, CaCl2 is the chemical formula for Calcium chloride and it shows is that the ratio of Calcium (Ca) to Chlorine (Cl) is 1:2.

The correct answer is C, the ratio of elements in the compound.

1. How many acetate ions are in the compound strontium acetate?

Answers

Answer: 2 Acetate ions

Explanation:

Strontium Acetate, has the molecular formular to be; C4H6O4Sr ( or in a linear form, Sr(CH3COO)2), contains two acetate ions.

In one molecule of strontium acetate (Sr(CH₃COO)₂), there are two acetate ions (CH₃COO⁻).

We must first comprehend the chemical composition of strontium acetate in order to calculate the quantity of acetate ions present.

Acetate ions (CH₃COO⁻) and strontium ions (Sr²⁺) combine to linear form the ionic compound strontium acetate. Sr(CH₃COO)₂ is the chemical formula for strontium acetate.

(CH₃COO)₂ stands for two acetate ions in the formula. The (CH₃COO⁻) ion, also referred to as the acetate ion, is a polyatomic ion made up of two carbon (C), three hydrogen (H), and two oxygen (O) atoms. It has a -1 charge overall.

Thus, there are two acetate ions (CH₃COO⁻) in a single molecule of strontium acetate (Sr(CH₃COO)₂).

It's crucial to understand that in ionic compounds like strontium acetate, the ratio of positively charged ions (cations) to negatively charged ions (anions) must be balanced in order to produce a neutral compound. In this instance, the two -1 charges of the acetate ions (CH₃COO⁻) counterbalance the two +2 charges of the strontium ions (Sr²⁺), creating a neutral molecule.

Answer: A)  0.20 L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to the neutralization law,

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1[/tex] = molarity of stock [tex]H_2SO_4[/tex] solution = 10.0 M

[tex]V_1[/tex] = volume of stock [tex]H_2SO_4[/tex]   solution = ?

[tex]M_2[/tex] = molarity of dilute [tex]H_2SO_4[/tex]  solution = 0.50 M

[tex]V_2[/tex] = volume of dilute [tex]H_2SO_4[/tex]  solution = 4.0 L

[tex]10.0\times V_1=0.50\times 4.0[/tex]
