A word equation is one that is written in words rather than using the normal symbols of the elements that are involved.

<h3>What is a word equation?</h3>

A word equation is one that is written in words rather than using the normal symbols of the elements that are involved. In this case we are asked to write the word equation for certain reactions and the states of matter of each of the terms in the reaction must be stated.

The word equations are as follows;

  • sodium carbonate solution(aq) +  silver nitrate solution(aq) ----> sodium nitrate(aq) + silver carbonate(aq)
  • potassium carbonate solution(aq) + nitric acid (hydrogen nitrate) solution(aq) -----> potassium nitrate(aq) + water(l) + carbon dioxide
  • barium nitrate solution (aq)+  potassium chromate solution(aq) -----> potassium nitrate (aq) + barium chromate (s)

Usimov [2.4K]

Answer:

m=7.07gH_{2}SO_{4}

Explanation:

1. Take in account the sulfuric acid at STP:

1840\frac{g}{L}

2. Density is expressed as the ratio between the mass and the volume of a substance so:

d=\frac{m}{V}

Solving for m:

m=\frac{V}{d}

3. Replace values:

m=\frac{1.30*10^{4}L}{1840\frac{g}{L}}

m=7.07gH_{2}SO_{4}

You measure the emission spectrum of an atom that you suspect to be hydrogen. You have no absolute calibration of the wavelength
trapecia [35]

Answer:

Explanation:

What we need to do here is to determine the ratios by using  the Rydberg equation starting with the transition to n1 = 1, 2,3, etc and see which one fits the data. Remember the question states that they are series and the wavelengths will be for increasing  energy levels.

1/λ = Rh x ( 1/n₁² - 1/n₂²)

Lyman series  ( n₁=1 and n₂= 2,3 etc)  for the first two lines, the ratios will be:

1/λ₁ /1/λ₂  =(1/1 -1/ 2²) / (1/1 -1/ 3²) ⇒ 0.84 ≠ 0.74  (the first ratio)

For Balmer series n₁ = 2  and n₂ = 3,4,5, etc

1/λ₁ /1/λ₂  =(1/4 -1/3²) / (1/4 -1/4²) ⇒ 0.741 = 0.741 (match!)

Lets use the third line to check our answer:

1/λ₁ /1/λ₂  =(1/4 -1/3²) / (1/4 -1/5²) = 0.66

A certain sample of a liquid has a mass of 42 grams and a volume of 35 centimeters3. What is the density of the liquid?
BabaBlast [244]

Answer:

            1.2 g.cm⁻³

Solution:

Data Given:

                             Mass  =  42 g

                             Volume  =  35 cm³

Formula Used:

                             Density  =  Mass ÷ Volume

Putting values,

                             Density  =  42 g ÷ 35 cm³

                             Density  =  1.2 g.cm⁻³
